安装squid3.0,配置squid3.0笔记

1.解开压缩包
tar xzf squid-3.0.RELEASE-src.tar.gz 
cd /usr/local/squid/src/ squid-*.*.RELEASE / 

2.安装到/opt/case/squid目录
./configure --prefix=/opt/case/squid
make
make install 

3.启动服务
(1)产生Squid所有的缓存目录,执行./sbin/squid –z
如果提示 visible_hostname错误 ,找到 visible_hostname ， 
加一行 visible_hostname xx.xx就好了
如果提示 Permission denied ,执行 chmod -R 777 var/cache
(2)启动服务 ./sbin/squid
观察Squid是否运行使用命令 ./sbin/squid -k check
