Varnish在Centos 7下的安装

Varnish在Centos 7下用yum安装很简单

yum install epel-release -y

执行后，会添加源在

more /etc/yum.repos.d/epel.repo

打开上面文件看内容

[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
enabled=1
failovermethod=priority
baseurl=http://mirrors.cloud.aliyuncs.com/epel/7/$basearch
gpgcheck=0
gpgkey=http://mirrors.cloud.aliyuncs.com/epel/RPM-GPG-KEY-EPEL-7

我是阿里云的机器，所以源是阿里云的。

php也直接有支持varnish的官方的函数了。
安装varnish的yum命令

yum install varnish -y

varnish的配置文件

vim /etc/varnish/default.vcl

具体的配置信息，看我另外一篇文章Varnish和WordPress的配置

vim /etc/varnish/varnish.params

varnish.params是varnish的端口和存储配置，默认是缓存到内存的
