Debian/Ubuntu命令方式快速安装squid

之前，我们介绍过如何通过源码方式在Debian下安装squid当然，那是个比较详细而且略微麻烦的过程。今天我们试试用较简单的apt命令方法安装squid服务。看看有与源码安装有何配置上的差异：

一、运行squid安装命令

root@netren:~# apt-get install squid

The following extra packages will be installed:
squid-common squid-langpack
Suggested packages:

squid squid-common squid-langpack  （这几个软件包将被安装）

二、完成安装，进行查看：

root@netren:~# netstat -tunlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN      1661/mysqld
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      2433/apache2
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      597/sshd
tcp        0      0 0.0.0.0:3128            0.0.0.0:*               LISTEN      2601/(squid) （squid端口正在监听运行）

三、squid在系统内的安装信息：

那么，它到底将安装目录及配置文件放在哪里了呢？
/etc/default/squid
/etc/init/squid.conf
/etc/init.d/squid （服务管理中添加了squid）
/etc/logrotate.d/squid （日志管理中添加了squid）  
/etc/resolvconf/update-libc.d/squid
/etc/squid/squid.conf （主要配置文件）
/usr/lib/squid/squid_session
/usr/lib/squid/squid_unix_group
/usr/lib/squid/unlinkd
/usr/lib/squid/wbinfo_group.pl
