在CentOS6.3最小化安装环境中需要安装的软件包
[root@squid ~]# yum install wget gcc gcc-c++ make perl
编译安装Squid
[root@squid ~]# cd squid-3.3.1 [root@squid squid-3.3.1]# ./configure --prefix=/usr/local/squid [root@squid squid-3.3.1]# make all [root@squid squid-3.3.1]# make install
安装完成后查看安装文件目录及配置文件
[root@squid squid-3.3.1]# cd /usr/local/squid/ [root@squid squid]# ls bin etc include lib libexec sbin share var [root@squid squid]# ls etc/ cachemgr.conf mime.conf squid.conf cachemgr.conf.default mime.conf.default squid.conf.default errorpage.css msntauth.conf squid.conf.documented errorpage.css.default msntauth.conf.default [root@squid squid]#
初始化前准备工作
赋予相关目录写权限
[root@squid etc]# chmod -R 777 /usr/local/squid/var/
指定主机名
[root@squid etc]# vi squid.conf visible_hostname 192.168.11.181
指定cache_mem大小
查看当前系统内存
[root@squid ~]# free total used free shared buffers cached Mem: 4019920 521536 3498384 0 34080 420512 -/+ buffers/cache: 66944 3952976 Swap: 4161528 0 4161528 [root@squid ~]#
[root@squid etc]# vi squid.conf cache_mem 2048 MB
指定缓存目录
61 # Uncomment and adjust the following to add a disk cache directory. 62 #cache_dir ufs /usr/local/squid/var/cache/squid 100 16 256
cache_dir ufs /usr/local/squid/var/cache/squid 4096 16 256
