Amazon Linux Varnish 3 配置

想起很久以前没有配置好的Varnish,于是便开始继续在自己的Instance上配置。

Amazon Linux Varnish

1.安装

yum install varnish

2.修改网站对应的端口

server
{
    listen 127.0.0.1:80;
    server_name aws.phodal.com;
    index index.html index.htm index.php default.html default.htm default.php;
    root  /home/www/MK_zhonghua;

    include wordpress.conf;
    location ~ .*\.(php|php5)?$
    {
        fastcgi_pass  unix:/tmp/php-cgi.sock;
        fastcgi_index index.php;
        include fcgi.conf;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
        expires      12h;
    }


}

注意: 这里需要将listen 80;改为127.0.0.1:80,以免Nginx Varnish端口之间的端口冲突。

3.修改/etc/sysconfig/varnish

查看一下自己的内网或者外网IP,如

ifconfig

就会得到下面的结果

eth0      Link encap:Ethernet  HWaddr 06:45:0E:9B:AA:77
          inet addr:172.31.26.24  Bcast:172.31.31.255  Mask:255.255.240.0
          inet6 addr: fe80::445:eff:fe9b:aa77/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:9001  Metric:1
          RX packets:201818 errors:0 dropped:0 overruns:0 frame:0
          TX packets:152864 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:23804259 (22.7 MiB)  TX bytes:190045784 (181.2 MiB)
          Interrupt:72

内网的IP就是172.31.26.24,拿到对应的结果,修改到/etc/sysconfig/varnish中。

VARNISH_LISTEN_ADDRESS=172.31.26.21
VARNISH_LISTEN_PORT=80

将VARNISH_LISTEN_ADDRESS改为内网的IP,PORT改为80.

4.修改/etc/varnish/default.vcl

backend phodalcms {
  .host = "127.0.0.1";
  .port = "80";
}

backend phodalblog {
  .host = "127.0.0.1";
  .port = "8080";
}

sub vcl_recv {
    if (req.http.host == "aws.phodal.com") {
            set req.http.host = "aws.phodal.com";
        set req.backend = phodalcms;
        return (lookup);
    } else if (req.http.host == "aws1.phodal.com") {
            set req.http.host = "aws1.phodal.com";
        set req.backend = phodalblog;
        return (lookup);
    } 
}

phodalcms对应的是80,对应的host是aws.phodal.com 而8080便是另外一个应用,对应的host是aws1.phodal.com

5.验证varnish default.vcl配置是否正确

varnishd -C -f /etc/varnish/default.vcl

6.重启服务

service nginx restart
service varnish restart

7.验证是否成功

curl -I -s aws.phodal.com

注意下面的X-Varnish

其他

查看端口占用

查看80端口

lsof -i:80

查看所有网络相关端口及信息

   netstat -punta

返回结果如下
