I have 1 server with 2 IP addresses:
eth0 = 1.2.3.4
eth0:0 = 5.6.7.8
/etc/hosts
127.0.0.1 localhost
1.2.3.4 domain1.com
5.6.7.8 domain2.net
In this server I have Apache running with the following configuration (/etc/httpd/conf/httpd.conf):
...
Listen 1.2.3.4:8080
Listen 5.6.7.8:8080
...
<VirtualHost 1.2.3.4:8080>
DocumentRoot /var/www/domain1.com/public_html
...
</VirtualHost>
<VirtualHost 5.6.7.8:8080>
DocumentRoot /var/www/domain2.net/public_html
...
</VirtualHost>
So far so good, and I can have my webserver working OK.
Then I have installed Varnish Cache, with the following parameters:
/etc/sysconfig/varnish
NFILES=131072
MEMLOCK=82000
NPROCS="unlimited"
RELOAD_VCL=1
VARNISH_LISTEN_PORT=80
DAEMON_OPTS="-a domain1.com:80 \
-T domain1.com:6082 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,256m"
DAEMON_OPTS="-a domain2.net:80 \
-T domain2.net:6083 \
-f /etc/varnish/default.vcl \
-S /etc/varnish/secret \
-s malloc,512m"
/etc/varnish/default.vcl
backend domain1 {
.host = "1.2.3.4";
.port = "8080";
}
backend domain2 {
.host = "5.6.7.8";
.port = "8080";
}
sub vcl_recv {
if (req.http.host == "domain1.com") {
set req.http.host = "domain1.com";
set req.backend = domain1;
return (lookup);
}
if (req.http.host == "domain2.net") {
set req.http.host = "domain2.net";
set req.backend = domain2;
return (lookup);
}
}
But I can reach the website domain2.net but not the domain1.com.
When querying the ports listening on my server, I can notice the following:
user@host# netstat -an | more
tcp 0 0 5.6.7.8:80 0.0.0.0:* LISTEN
tcp 0 0 5.6.7.8:8080 0.0.0.0:* LISTEN
tcp 0 0 1.2.3.4:8080 0.0.0.0:* LISTEN
tcp 0 0 5.6.7.8:6083 0.0.0.0:* LISTEN
Does anyone know why is Varnish ignoring all 1.2.3.4 / domain1.com configuration? And how to make it work?
Thanks in advance.
