• Ruby on Rails - How to migrate code from float to decimal?

  - by user1723110

  So I've got a ruby on rails code which use float a lot (lots of "to_f"). It uses a database with some numbers also stored as "float" type. I would like to migrate this code and the database to decimal only. Is it as simple as migrating the database columns to decimal (adding a decimal column, copying float column to decimal one, deleting float column, renaming decimal column to old float column name), and replacing "to_f" with "to_d" in the code? Or do I need to do more than that? Thanks a lot everyone Raphael

• trouble running multiple domains on tomcat behind apache via mod_jk

  - by mkoryak

  I am having trouble setting up tomcat6 with 2 virtual hosts, behind apache2. if i have just one host defined in tomcat, and one jk worker, everything works fine. as soon as i define another jk worker and a corresponding tomcat host i get this error in jk.log: 9:3075328656] [info] ajp_connect_to_endpoint::jk_ajp_common.c (922): Failed opening socket to (69.164.218.75:8009) (errno=111) [Tue Feb 08 03:08:13 2011] [17159:3075328656] [error] ajp_send_request::jk_ajp_common.c (1507): (dogself) connecting to backend failed.

• Apache, Tomcat and mod_jk for load balancing

  - by pHk

  Hi guys. I've set-up a basic Apache (2.2.x) and Tomcat (6.0.x) set-up using mod_jk for load balancing using the worker.properties file. Preliminary testing seems to show that this works relatively well, and it was quite easy to set-up. However; the fact that it was so easy to set-up has got me a little worried. We're dealing with 100 - 300 concurrent users using the same web application (deployed on 2 or 3 Tomcat instances). I have done a little Googling and looking around on here and there seems to be more than 1 way to accomplish this (one example on here used a balancer:// style URL, which I've never seen before in an Apache config). For example, one question I ask myself is how reliable the load detection on mod_jk really is (Busyness, Session, Request, etc). In your experience, does this set-up prove to be reliable in real world scenarios? Any pointers on improvements, pit falls or interesting literature/articles? I've worked with Apache before, but am in no way an expert. Thanks in advance.

• RewriteRule Works With "Match Everything" Pattern But Not Directory Pattern

  - by kgrote

  I'm trying to redirect newsletter URLs from my local server to an Amazon S3 bucket. So I want to redirect from: https://mysite.com/assets/img/newsletter/Jan12_Newsletter.html to: https://s3.amazonaws.com/mybucket/newsletters/legacy/Jan12_Newsletter.html Here's the first part of my rule: RewriteEngine On RewriteBase / # Is it in the newsletters directory RewriteCond %{REQUEST_URI} ^(/assets/img/newsletter/)(.+) [NC] # Is not a 2008-2011 newsletter RewriteCond %{REQUEST_URI} !(.+)(11|10|09|08)_Newsletter.html$ [NC] ## -> RewriteRule to S3 Here <- ## If I use this RewriteRule to point to the new subdirectory on S3 it will NOT redirect: RewriteRule ^(/assets/img/newsletter/)(.+) https://s3.amazonaws.com/mybucket/newsletters/legacy/$2 [R=301,L] However if I use a blanket expression to capture the entire file path it WILL redirect: RewriteRule ^(.*)$ https://s3.amazonaws.com/mybucket/newsletters/legacy/$1 [R=301,L] Why does it only work with a "match everything" expression but not a more specific expression?

• Having trouble keeping a 1GB RAM Centos server running

  - by Josh

  This is my first time configuring a VPS server and I'm having a few issues. We're running Wordpress on a 1GB Centos server configured per the internet (online research). No custom queries or anything crazy but closing in on 8K posts. At arbitrary intervals, the server just goes down. From the client side, it just says "Loading..." and will spin more or less indefinitely. On the server side, the shell will lock completely. We have to do a hard reboot from the control panel and then everything is fine. Watching "top" I see it hovering between 35 - 55% memory usage generally and occasional spikes up to around 80%. When I saw it go down, there were about 30 - 40 Apache processes showing which pushed memory over the edge. "error_log" tells me that maxclients was reached right before each reboot instance. I've tried tinkering with that but to no avail. I think we'll probably need to bump the server up to the next RAM level but with ~120K pageviews per month, it seems like that's a bit overkill since it was running fairly well on a shared server before. Any ideas? httpd.conf and my.cnf values to add? I'll update this with the current ones if that helps. Thanks in advance! This has been a fun and important learning experience but, overall, quite frustrating!

• PHP files are downloaded, not executed in UserDir on Apache

  - by Fabian

  We're running a webserver using Debian 6.0.3 with Apache 2, we recently upgraded from Debian 5 to 6. Since then php scripts in the user directories (using mod_userdir) have stopped working, they are downloaded instead of being executed. There is also a website using php outside of the user directories, and that one continues to work fine, so PHP seems to generally work on the server. I tested it with several PHP files, among the a simple phpinfo file that works fine on the main site, but is just downloaded when copying it to one of the user directories. The php files and the directory containing them are executable for everyone. The option in the Apache php5.conf that by default disables PHP in the user directories, is commented out, so the php5.ini looks like this: <IfModule mod_php5.c> <FilesMatch "\.ph(p3?|tml)$"> SetHandler application/x-httpd-php </FilesMatch> <FilesMatch "\.phps$"> SetHandler application/x-httpd-php-source </FilesMatch> # To re-enable php in user directories comment the following lines # (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it # prevents .htaccess files from disabling it. #<IfModule mod_userdir.c> # <Directory /home/*/public_html> # php_admin_value engine Off # </Directory> #</IfModule> </IfModule> We restarted Apache after changing this. I'm running out of ideas now what the problem could be, and I don't know how I could really determine which problem is preventing those php files from being executed. Any ideas on how I can solve this? Update: Strangely, PHP seems to work fine in subfolders of user directories, so if I copy a PHP file from /home/user/public_html/ to /home/user/public_html/test/ it suddenly works.

• how do I setup Apache's Content-Encoding Header?

  - by Nick

  When attempting to validate my site with the W3C validator, it returns the error, "Don't know how to decode Content-Encoding 'none'". Firebug confirms that my server is sending the header, "Content-Encoding: none". But I can't find any directive in apache2.conf or in my vhost that sets the Content-Encoding header. Where does the directive go, and what should it be set to? UPDATE: On further examination it seems something is wrong with mod_deflate (gzip). It's zipping my css files just fine, but is not zipping the html generated by my php scripts. I have: AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css And the pages are showing a mime type of: "text/html". But content encoding is "none" and they aren't zipping. Perhaps these issues are related?

  just wondering how I add a trailing slash at the end of my URL's using Mod_Rewrite?

• Apache inflate application/ with mod_filter

  - by BGT

  I need to prevent pdf objects from being gzipped. Really, this only needs to take place if the request is from the Mozilla browser (but since I can't get something as seemingly simple as no-gzip for application/pdf, I figure it's wiser to start there). From looking at the apache documentation on mod_filter, I've got the following: <Location /> FilterDeclare gzipDeflate CONTENT_SET FilterDeclare gzipInflate CONTENT_SET FilterProvider gzipDeflate deflate req=User-Agent $Mozilla/ FilterProvider gzipInflate inflate resp=Content-Type $application/ FilterChain +gzipDeflate +gzipInflate </Location> From my testing, the gzipDeflate filter is doing its job and all the pages without the Content-Type starting with application are being gzipped. But, the gzipInflate doesn't seem to be working at all. I've inspected the response in Firebug and verified that the Content-Type being sent down is application/pdf. I'll go ahead and ask a potentially stupid question though: The response's Content-Type header in its entirety read "application/pdf; charset=Windows-1252". Does that make any sort of difference or is $application/ presumably enough to catch that? Any help is greatly appreciated. One other point, the URL that returns the pdf object does not have the .pdf extension. The pdf itself is stored in an Oracle database as a blob and appended to the page when appropriate (all the urls in the system use the same baseline). This was part of an original inquiry by a helpful member at stackoverflow who pointed me towards mod_filter and suggested I post the question here.

• Apache server rewrite rules: how to avoid "implicitly forcing redirect (rc=302)"?

  - by Olivier Pons

  Hi! I've got a very annoying problem: our webserver handles 2 (more actually but let's say 2 for a simpler example): pretassur.fr pretassuragentimmobilier.fr Here's what I want to do: change (whatever1).pretassuragentimmobilier.fr(/whatever2) to (whatever1).pretassur.fr(/whatever2)?theme=agentimmobilier So here's my rewriterule: RewriteCond %{SERVER_NAME} (([a-z]+\.)*)pretassuragentimmobilier.(fr|com) RewriteRule ^(.+) http://%1pretassur.fr$1 [E=THEME:pretassur_agent,QSA] # if THEME not empty, set it : RewriteCond %{ENV:THEME} ^(.+)$ RewriteRule (.*) $1?IDP=%{ENV:THEME} [QSA] The big (huge) problem is: let's have a look at the rewrite logs: [pretassurmandataireimmo.com] (5) => setting env variable 'THEME' to 'pretassur_mandataire' [pretassurmandataireimmo.com] => (2) implicitly forcing redirect (rc=302) with http://pretassur.fr/ Aaaaaaaaarg! "implicitly forcing redirect" = I don't want that ! I want to internally redirect to pretassur.fr, not to make a real redirect! Now if you type: http://pretassurmandataireimmo.com it is redirected to http://pretassur.fr/?IDP=pretassur_mandataire (try it) I don't want that! I want to display this page http://pretassur.fr/?IDP=pretassur_mandataire but without touching the original host! Any idea? Thanks a lot!

• Apache SSL for login and NON-SSL for everything else (.htacces)

  - by The Devil

  Hey I've almost figured it out on my own but there's something I'm missing. I want to set a couple of directories and files to require SSL and everything else that's not related to those files and dirs to point back to http. So far I have this: RewriteEngine on RewriteBase / # Force ssl for login & admin RewriteCond %{HTTPS} !on RewriteRule ^/?(admin(.*)|login\.php)$ https://%{SERVER_NAME}/$1 [R,NC,L] # Force non-ssl for others RewriteCond %{HTTPS} on RewriteRule ^/?(admin(.*)|login\.php)$ http://%{SERVER_NAME}/$1 [R,NC,L] I'm sure I'm doing something wrong but I just can't figure it out.... The first condition works perfect - whenever I access login.php or /admin/ it points to https. But the second one doesn't... Where have I mistaken ? Thanks in advance!

• AJP Connector Apache-Tomcat with php and java application

  - by Safari

  I have a question about proxy and ajp module. On my machine I have a Apache web server and a Tomcat servlet container. On Tomcat is running a my java webapplication. On Apache I have some services and I can call these in this way: http://myhos/service1 http://myhos/service2 http://myhos/service3 I would configurate a ajp connector to call my tomcat webapplication from Apache. I would somethin as http://myhost to call the Tomcat webapp. So, I configurated my apache in this way..and I have what I wanted: I can use http://myHost to visualize the Tomcat webApp by Apache. <VirtualHost *:80> ProxyRequests off ProxyPreserveHost On ServerAlias myserveralias ErrorLog logs/error.log CustomLog logs/access.log common <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /server-status !

• Forgot password to development database

  - by ninja08

  I've created a database using terminal while following along with a tutorial. Although I had a lot of trouble getting the databases to install. Now after finally getting it to work I changed a few things, actually just the name of the database using the rake command to just "next". The password should be 'secret password'. How can I change the password or find out what it is or change it? It doesn't seem to be edited my databases.yml file with the password, especially since it still just says 'root' as username with now password in there.

• Question about RewriteRule and HTTP_HOST server variable

  - by SeancoJr

  In evaluating a rewrite rule that redirects to a specific URL and say the rewrite condition is met, would it be possible to use HTTP_HOST as part of the URL to be redirected to? Example in question: RewriteRule .*\.(jpg|jpe?g|gif|png|bmp)$ http://%{HTTP_HOST}/no-leech.jpg [R,NC] The motive behind this question is a desire to create a single htaccess file that would match against an addon domain (on a shared hosting account) and an infinite amount of subdomains below it to prevent hotlinking of images.

• Apache htaccess with mod_expires Not Working for certain directories

  - by keyboarddrummer

  I have a Joomla site that I am trying to enable caching using mod_expires. I have the .htaccess in the root of the site and have added the options as found on the page http://www.pactsoftware.nl/tools/joomla-optimization.html Using the PageSpeed extension in Chrome, prior to adding this in my .htaccess, my site scores a 55 (Caching is at the top, and lists a lot of images, CSS, and JS files). After these directives, it scores 70, with caching in the yellow, but still lists some image files (some are two directories deep and the rest are four). I checked for any other .htaccess files in the Joomla root, but none are between those folders and the root. It is almost as if htaccess only works in that one directory, not the subfolders. I have tried putting a .htaccess in each affected subdirectory, but it does not work. Does anyone have any ideas?

• mod_rpaf problems with Nginx front, Apache back-end after Ubuntu upgrade

  - by Kenn

  I'm running an Nginx front-end for static files, and proxying to an Apache backend for PHP and Passenger, using Apache's mod_rpaf to set the correct remote IP address on the backend. Everything worked fine until I upgraded to Ubuntu 12.04 (Precise). Now Apache reports all connections coming from 127.0.0.1. Here's the relevant configuration. Nothing here changed with the upgrade. Nginx: proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; mod_rpaf: <IfModule mod_rpaf.c> RPAFenable On RPAFsethostname On RPAFproxy_ips 127.0.0.1 ::1 RPAFheader X-Forwarded-For </IfModule> I'm using %{X-Forwarded-For}i in my Apache LogFormat directive and the access logs are showing the correct remote address, so I know Nginx is passing the address along properly. In a phpinfo() test, HTTP_X_FORWARDED_FOR is showing the correct remote address, but REMOTE_ADDR is 127.0.0.1. This is reflected in PHP applications as well, such as WordPress comments. I've tried switching Nginx and mod_rpaf to X-Real-IP with no effect. Did something change that I missed? Relevant version info, everything installed from the Ubuntu repository: Nginx 1.1.19 Apache 2.2.22 mod_rpaf 0.6

• How to Remove Extensions From, and Force the Trailing Slash at the End of URLs?

  - by Kronbernkzion

  Example of current file structure: example.com/foo.php example.com/bar.html example.com/directory/ example.com/directory/foo.php example.com/directory/bar.html example.com/cgi-bin/directory/foo.cgi I want to remove HTML, PHP and CGI extensions from, and then force the trailing slash at the end of URLs. So, it could look like this: example.com/foo/ example.com/bar/ example.com/directory/ example.com/directory/foo/ example.com/directory/bar/ example.com/cgi-bin/directory/foo/ I've searched for solution for 17 hours straight and visited more than a few hundred pages on various blogs and forums. I'm not joking. So I think I've done my research. Here is the code that sits in my .htaccess file right now: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(([^/]+/)*[^./]+)/$ $1.html RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]|/)$ RewriteRule (.*)$ /$1/ [R=301,L] As you can see, this code only removes .html (and I'm not very happy with it because I think it could be done a lot simpler). I can remove the extension from PHP files when I rename them to .html through .htaccess, but that's not what I want. I want to remove it straight. This is the first thing I don't know how to do. The second thing is actually very annoying. My .htaccess file with code above, adds .html/ to every string entered after example.com/directory/foo/. So if I enter example.com/directory/foo/bar (obviously /bar doesn't exist since foo is a file), instead of just displaying message that page is not found, it converts it to example.com/directory/foo/bar.html/, then searches for a file for a few seconds and then displays the not found message. This, of course, is bad behavior. So, once again, I need the code in .htaccess to do the following things: Remove .html extension Remove .php extension Remove .cgi extension Force the trailing slash at the end of URLs Requests should behave correctly (no adding trailing slashes or extensions to strings if file or directory doesn't exist on server) Code should be as simple as possible I would very much appreciate any help. And to first person that gives me the solution, I'll send two $50 iTunes Store gift cards for US store. If this offend anyone, I am truly sorry and I apologize. Thanks in advance. And sorry for such a long post.

• Windows + Django + mod_wsgi = "DLL load failed"

  - by Kyle MacFarlane

  For a long time I was using Python 2.5 to do all this fine but recently upgraded to 2.7 since building stuff for 2.5 is a real pain. I also updated mod_wsgi to 3.3 for Python 2.7. Everything is working fine with Apache + mod_wsgi on CentOS and also in the Django runserver on both Windows and CentOS, but not with Apache + mod_wsgi on Windows. Whenever I try to access a page in my Django app I get the following (note that Apache starts fine): ImportError at / DLL load failed: The specified module could not be found. Which is caused by things like: from Crypto.Cipher import AES Etree and others cause the exact same error and it is not limited to any specific packages. Anything with pyd files fails. Googling around suggests reinstalling Python "for all users", but the installer doesn't give you that option anymore anyway. For good measure I've tried reinstalling Python 2.7 as an administrator and also told it to register itself as the default version of Python but neither helped. I think the solution might have something to do with: The fact that I have 2.5, 2.6 and 2.7 installed on this machine and mod_wsgi might be loading the DLLs for 2.5 instead of 2.7. Something to do with WSGIPythonPath, which I usually don't need to set.

  Hello, Whenever I try to import a mysqldump export on another server, the triggers are never created, and if I remember correctly, I get an error messages that super user permission is required. IF I remove the definer it usually works but if there is a way I would prefer not having to edit the sql file. When I just simply copy over the mdi, mdy and frm files everything works perfectly. How could I import a mysqldump file so that triggers are created as well?

• How to change .htaccess file to work right in localhost?

  - by Manolo Salsas

  I have this snippet code in my .htaccess file to prevent users from hotlinking the server's images: RewriteEngine On RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} !^http://(www.)?itransformer.es/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ http://itransformer.es [R,L] Of course, it is not working in my localhost, but don't know how to achieve it. My guess is that I should change the domain name with any wildcard. Any idea? Update I've finally found out the answer thanks to @Chris solution: RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} ^https?://%{HTTP_HOST}/.*/usuarios/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ http://%{HTTP_HOST} [R=301,L] The /usuarios/ directory is because I only want to deny direct access to files inside this directory. Update2 For some reason, it doesn't work again. Finally I think that I found out a better solution: RewriteCond %{REQUEST_FILENAME} .*/usuarios/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ http://%{HTTP_HOST} [R=301,L] I say better solution because what I want to deny is direct access to a file (image). Update3 Well, after a while I discovered above wasn't exactly what I wanted, so the next is definitive: RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} !^https?://itransformer.*$ [NC] RewriteRule /usuarios/.*\.(gif|jpe?g|png|wbmp)$ - [R=404,L] Just two doubts: If I change the above to: RewriteCond %{HTTP_REFERER} ^$ [OR] RewriteCond %{HTTP_REFERER} !^https?://%{HTTP_HOST}.*$ [NC] RewriteRule /usuarios/.*\.(gif|jpe?g|png|wbmp)$ - [R=404,L] it doesn't work. I don't understand why, because %{HTTP_HOST} is equal to itransformer in my localhost, and it should work. The second doubt is why is shown the default 404 page and not my custom page (that is shown in all other 404 responses).

• mod_fcgi in virtualmin: graceful kill fail, sending SIGKILL?

  - by mgjk

  Yesterday around 1am, our server ground to a crawl. This doesn't happen often, but I'm trying to get to the bottom of it. There is no unusual traffic volume, no unusual processes running, just all of the sudden the server started killing fcgid processes. [Thu Aug 02 01:17:32 2012] [warn] mod_fcgid: process 26460 graceful kill fail, sending SIGKILL ... for as many fcgid processes as we have... CPU idle fell to 0% and I/O seemed to take up most of the load. The issue lasted about 5 minutes. I suspect there was some swap activity, although I'm not sure if it was due to killed processes being swapped in to die, or if it was because some process ramped up memory usage faster than my process watching scripts can see them. The oom-killer wasn't triggered (at least it's not logged), so I think this was Apache for some reason restarting the processes. This is not regular, and nothing obvious appears in cron. Is there a normal Apache process which might cause this? We run dozens of different sites, and it was late at night, so volume was very, very low. (maybe 200 requests in a 10 minute period).

• rewrite redirect issue in debian squeeze

  - by hd01

  My server os is debian squeeze. I have these lines to redirect non-www to www in htaccess file of my website: RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC] RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] but it cause this error in firefox: The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies. when I comment those lines in htaccess mysite appears but in non-www format. I'm sure it works well before on the Ubuntu . but I don't know why it doesn't work now. would you help me?
