本篇內(nèi)容主要講解“varnish怎么配置”，感興趣的朋友不妨來(lái)看看。本文介紹的方法操作簡(jiǎn)單快捷，實(shí)用性強(qiáng)。下面就讓小編來(lái)帶大家學(xué)習(xí)“varnish怎么配置”吧!
server1:172.25.254.20 varnish
server2:172.25.254.21 http
主機(jī):172.25.254.44
Varnish是一款高性能的開源HTTP加速器
在server1上:
#yum install varnish-3.0.5-1.el6.x86_64.rpm varnish-libs-3.0.5-1.el6.x86_64.rpm -y
# vim /etc/varnish/default.vcl
backend web1 {
.host = "127.0.0.1";
.port = "8080";
} #定義本機(jī)端口
sub vcl_deliver {
if (obj.hits > 0) {
set resp.http.X-Cache = "HIT from westos cache";
}
else {
set resp.http.X-Cache = "MISS from westos cache";
}
return (deliver);
} #定義是否命中
# yum install httpd -y
# cd /var/www/html
# echo server20.example.com > index.html
# vim /etc/httpd/conf/httpd.conf
# Listen 12.34.56.78:80
Listen 8080 #修改http端口，防止和varnish端口沖突
# /etc/init.d/httpd start
# netstat -antlp #查看http 8080 端口是否開啟
# vim /etc/sysconfig/varnish
VARNISH_LISTEN_PORT=80 # varnish端口
# /etc/init.d/varnish start
[root@server20 html]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination #查看本機(jī)火墻是否關(guān)閉
[root@foundation44 Desktop]# curl -I 172.25.254.20

# vim /etc/varnish/default.vcl
backend web2 {
.host = "172.25.254.21";
.port = "80";
}
director lb random { #把多個(gè)后端聚合在一起
{ .backend = web1;
.weight = 1;
}
{ .backend = web2;
.weight = 2;
}
}
sub vcl_recv {
if (req.http.host ~ "^(www.)?westos.org") {
set req.http.host = "www.westos.org";
set req.backend = lb;
return(pass); #為了方便，所以定義不緩存
} elsif (req.http.host ~ "^bbs.westos.org") {
set req.backend = web2;
} else {
error 404 "westos cache";
}
} #如果訪問(wèn)其他會(huì)報(bào)錯(cuò) 404
# /etc/init.d/varnish reload
在server2上進(jìn)行的操作
yum install httpd -y
# cd /var/www/html
# echo server21.example.com > index.html
# /etc/init.d/httpd start
# vim /etc/httpd/conf/httpd.conf
NameVirtualHost *:80
DocumentRoot /var/www/html
ServerName www.westos.org
serveralias westos.org
DocumentRoot /var/www/virtualhost/bbs
ServerName bbs.westos.org
# mkdir -p /var/www/virtualhost/bbs
# cd /var/www/virtualhost/bbs/
# echo bbs.example.com > index.html
# /etc/init.d/httpd restart
# vim /etc/httpd/conf/httpd.conf
# /etc/init.d/httpd restart
然后在主機(jī)上加上 server1上和server2上相關(guān)的解析，在主機(jī)上火狐訪問(wèn)，或者用 curl -I www.westos.org
