What is causing apache2 proxy error when forwarding to tomcat?
- by Dark Star1
I set up apache to proxy for tomcat but I am getting the following error when I target the page. I sometimes get a blank page or a 503:
[Error]
[Mon Dec 03 04:58:16 2012] [error] proxy: ap_get_scoreboard_lb(2) failed in child 29611 for worker proxy:reverse
[Mon Dec 03 04:58:16 2012] [error] proxy: ap_get_scoreboard_lb(1) failed in child 29611 for worker https://localhost:8443/
[Mon Dec 03 04:58:16 2012] [error] proxy: ap_get_scoreboard_lb(0) failed in child 29611 for worker http://localhost:8080/
I have two vhosts configured on the vm as follows:
[http host]
<VirtualHost *:80>
ServerName www.mysite.net
ServerAlias mysite.net
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://localhost:8080/ retry=0
ProxyPassReverse / http://localhost:8080/ retry=0
</VirtualHost>
[ssl vhost]
<VirtualHost *:443>
ServerName www.mysite.net
ServerAlias mysite.net
ErrorLog /var/log/apache2/error.log
LogLevel warn
CustomLog /var/log/apache2/access.log combined
ServerSignature On
SSLEngine on
SSLProxyEngine on
SSLCertificateFile /etc/apache2/ssl/server.crt
SSLCertificateKeyFile /etc/apache2/ssl/server.key
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / https://localhost:8443/ retry=0
ProxyPassReverse / https://localhost:8443/ retry=0
</VirtualHost>
My system details are: Apache/2.2.22 (Ubuntu) mod_jk/1.2.32 mod_ssl/2.2.22 OpenSSL/1.0.1
mod proxy_http is also enabled.
