squid 3.5配置实现用户认证

安装squid

yum -y install squid

修改配置

1. 将原有的配置文件/etc/squid/squid.conf 清空

2. 贴上自己的配置

   http_port 0.0.0.0:8888 # 支持ipv4和ipv6，代理端口
   cache_dir ufs /var/spool/squid 1000 64 1024 #缓存目录
   cache_access_log /var/log/squid/access.log #接入的日志文件
   cache_log /var/log/squid/access.log #缓存的日志
   cache_store_log /var/log/squid/store.log #存储日志
   pid_filename /var/run/squid.pid # 进程id

   cache_mem 32 MB #缓存的大小
   cache_swap_low 90 #最小的交换空间
   cache_swap_high 95 #最大的交换空间
   maximum_object_size 4096 KB
   #maximum_object_size_in_memory 8 KB

3. 创建加密的账户和密码文件

   touch /etc/squid/squid_passwd

   chmod o+r /etc/squid/squid_passwd

   htpasswd /etc/squid/squid_passwd [username] #提示输入两次密码

4. 检查配置

   squid -k parse

   [root@docker-test squid]# squid -k parse

   以上表示配置正确。

5. 启动代理服务

   service squid start

6. 测试代理服务器

   打开浏览器的高级-> 系统->代理

   添加ip和port

   代开浏览器：跳出登录账户和密码
