squid3 配置要点

 

首先需要apt-get update

 

然后安装apt-get install squid

 

3、配置和开启

   vi /usr/local/squid/etc/squid.conf

   3.1更改监听端口

      http_port 9090

   3.2更改访问控制

      http_access allow all

   3.3开启squid

      3.3.1初始化squid.conf里的cache目录

------------------非常重要的命令-----------------

           /usr/local/squid/sbin/squid -z 

      3.3.2对squid.conf进行排错

           /usr/local/squid/sbin/squid -k parse

      3.3.3前台启动squid

           /usr/local/squid/sbin/squid -N -d1

      3.3.4后台运行squid

           /usr/local/squid/sbin/squid -s

      3.3.5 停止

           /usr/local/squid/sbin/squid -k shutdown

      3.3.5重新引导修改过的squid.conf

           /usr/local/squid/sbin/squid -k reconfigure

squid 最终的解决问题不在于上面的配置。而在于相关日志、缓存文件的权限；

squid 3 显示启动：squid3 -N -d1,发现     

直接赋予swap.state文件夹权限，即可。

同时，对于access.log,cache.log 的日志权限也需要考虑提前变更。这些在squid3 -k parse 中就已经提到。

2013年7月16日 

asset ion failure mem->swap out.sio=self  出现此错误，目前公网上找不到答案，唯一解决方案就是减少IP，不再分配新的ip；或者是通过squid3 -z 重新初始化目录

---

切记：以后再改动conf 文件的时候，先将原来的文件进行备份。
