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

/usr/lib/squid/yp_auth

/usr/sbin/squid （添加了squid命令到sbin目录）

/usr/share/squid （添加了squid共享文档目录）

/usr/share/squid-langpack （添加了squid语言包的共享文档目录）

/usr/share/doc/squid （添加了squid说明文档目录）

/usr/share/squid/errors （添加了squid多国语言的报错文档目录）

/usr/share/squid-langpack/en/ERR_FTP_FAILURE

/usr/share/squid-langpack/zh-cn/ERR_CONNECT_FAIL （squid多国语言的报错文档目录）

/usr/share/squid-langpack/zh-cn/ERR_DIR_LISTING

/usr/share/squid-langpack/zh-tw/ERR_WRITE_ERROR

/usr/share/squid-langpack/zh-tw/ERR_ZERO_SIZE_OBJECT

/var/log/squid （squid日志文件目录）

/var/spool/squid （是其默认安装的缓冲目录）

root@netren:/var/spool/squid# ls

00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F swap.state

并且为系统新建了名为proxy的用户和组

root@netren:~# grep proxy /etc/passwd /etc/group

/etc/passwd:proxy:x:13:13:proxy:/bin:/bin/sh

/etc/group:proxy:x:13:

四、如何启动或停止squdi？

启动squid程序：

方法1、root@netren:~# squid 直接以命令形式运行squid

方法2、root@netren:~# /etc/init.d/squid start 通过程序管理器（脚本）来运行squid

Rather than invoking init scripts through /etc/init.d, use the service(8)

utility, e.g. service squid start

Since the script you are attempting to invoke has been converted to an

Upstart job, you may also use the start(8) utility, e.g. start squid

squid start/running, process 2718

停止squid程序：

方法1、root@netren:~# squid -k shutdown 进行停止

方法2、root@netren:~# /etc/init.d/squid stop 通过程序管理器（脚本）来停止squid

Rather than invoking init scripts through /etc/init.d, use the service(8)

utility, e.g. service squid stop

Since the script you are attempting to invoke has been converted to an

Upstart job, you may also use the stop(8) utility, e.g. stop squid

squid stop/waiting
