怎么样在CentOS/Redhat中安装Varnish 3

    简单的说Varnish是一款高性能的开源HTTP加速器，具体的介绍大家可以从查看。

话不多说，直接开始操作过程。

本次介绍的是使用Varnish官方提供的发布包安装方式。安装说明可参考官方帮助文档

如果是在CentOS5/Redhat5系统下安装

# rpm --nosignature -i

如果是在CentOS6/Redhat6系统下安装

# rpm --nosignature -i 

然后

# yum install varnish

如果出现以下错误

  --> Missing Dependency: libedit.so.0()(64bit) is needed by package varnish-3.0.5-1.el5.centos.x86_64 (varnish-3.0)

Error: Missing Dependency: libedit.so.0()(64bit) is needed by package varnish-3.0.5-1.el5.centos.x86_64 (varnish-3.0)

 You could try using --skip-broken to work around the problem

 You could try running: package-cleanup --problems

                        package-cleanup --dupes

                        rpm -Va --nofiles --nodigest

The program package-cleanup is found in the yum-utils package.

修复处理方法如下，配置epel仓库即可

如果你的系统是centos5/redhat5的i386架构

# rpm -Uvh

如果是x86_64架构

# rpm -Uvh

同理，假如是centos6/redhat6的i386架构

# rpm -Uvh 

如果是x86_64架构

# rpm -Uvh 

安装完之后，再执行

# yum install varnish

配置varnish启动

# /etc/init.d/varnish start

# chkconfig --level 345 varnish on

Varnish配置

/etc/varnish/ 存放varnish VCL配置文件
/etc/sysconfig/varnish 【CentOS】 存放varnish服务器运行的参数
/usr/sbin/varnishd varnish服务器执行文件
/etc/init.d/varnish 运行程序
