centos6.3 varnish3.03 get the wrong backend
- by Sola.Shawn
I install varnish3.03 with yum! I got a problem with it
my varnish config bellow:**
#
#backend weibo {
.host = "192.168.1.178";
.port = "8080";
.connect_timeout=20s;
.first_byte_timeout=20s;
.between_bytes_timeout=20s;
}
#backend smth {
.host = "192.168.1.115";
.port = "8080";
.connect_timeout=20s;
.first_byte_timeout=20s;
.between_bytes_timeout=20s;
}
#sub vcl_recv {
if (req.restarts == 0) {
if (req.http.x-forwarded-for) {
set req.http.X-Forwarded-For =
req.http.X-Forwarded-For + ", " + client.ip;
} else {
set req.http.X-Forwarded-For = client.ip;
}
}
if (req.request != "GET" &&
req.request != "HEAD" &&
req.request != "PUT" &&
req.request != "POST" &&
req.request != "TRACE" &&
req.request != "OPTIONS" &&
req.request != "DELETE") {
# /* Non-RFC2616 or CONNECT which is weird. */
return(pipe);
}
if (req.request != "GET" && req.request != "HEAD") {
# /* We only deal with GET and HEAD by default */
return(pass);
}
if (req.http.Authorization || req.http.Cookie) {
/* Not cacheable by default */
return(pass);
}
if (req.http.host ~ "^(hk.)?weibo.com"){
set req.http.host = "hk.weibo.com";
set req.backend = weibo;
}
elseif (req.http.host ~ "^(www.)?newsmth.net"){
set req.http.host = "www.newsmth.net";
set req.backend = smth;
}
else {
error 404 "Unknown virtual host";
}
return(lookup);
}
##sub vcl_pipe {
return(pipe);
}
#sub vcl_pass {
return(pass);
}
#sub vcl_hash {
hash_data(req.url);
if(req.http.host) {
hash_data(req.http.host);
} else {
hash_data(server.ip);
}
return(hash);
}
#sub vcl_hit {
if(req.http.Cache-Control~"no-cache"||req.http.Cache-Control~"max-age=0"||req.http.Pragma~"no-cache"){
set obj.ttl=0s;
return (restart);
}
return(deliver);
}
#sub vcl_miss {
return(fetch);
}
#sub vcl_fetch {
if (beresp.ttl <= 120s ||
beresp.http.Set-Cookie ||
beresp.http.Vary == "*") {
/*
* Mark as "Hit-For-Pass" for the next 2 minutes
*/
set beresp.ttl = 10s;
return (hit_for_pass);
}
return(deliver);
}
#sub vcl_deliver {
return(deliver);
}
#sub vcl_init {
return(ok);
}
#sub vcl_fini {
return(ok);
}
and my Win7's hosts file add bellow:
192.168.1.178 www.newsmth.net
192.168.1.178 hk.weibo.com
start varnish
varnishd -f /etc/varnish/dd.vcl -s malloc,100M -a 0.0.0.0:8000 -T 0.0.0.0:3500<br>
but when I access the "hk.weibo.com:8000" it fine, and got:
Hello,I am hk.weibo.com!
but when access http://www.newsmth.net:8000/, got:
Hello,I am hk.weibo.com! <br>
My question is why it isn't "Hello,I am www.newsmth.net!"?
varnish fetched the content from the wrong backend. Does anyone know how to fix this?
