购买一台服务器设置为代理服务器
目前购买系统为CentOS 8.2 64位
这次安装squid软件作为设置代理服务器
squid软件就不多介绍了，google下很多解释
直接讲解安装过程
1. 检测squid是否安装过
[php]rpm -qa squid[/php]
或者
[php]whereis squid[/php]
2. 没有安装的话进行安装
[php]yum install -y squid[/php]
或者
[php]dnf install -y squid[/php]
3. 安装完成后启用代理
[php]systemctl enable –now squid.service[/php]
[php]systemctl status squid.service[/php]
返回结果如下：
[php]
[root@Server-i-v4e3m1nid9 ~]# systemctl enable –now squid.service
Created symlink /etc/systemd/system/multi-user.target.wants/squid.service → /usr /lib/systemd/system/squid.service.
[root@Server-i-v4e3m1nid9 ~]# systemctl status squid.service

4. 好后看下防火墙是否开启，有开启的话设置允许squid代理服务
[php]firewall-cmd –permanent –add-service=squid[/php]
[php]firewall-cmd –reload[/php]
5. 进入配置文件目录
[php]cd /etc/squid/[/php]
编辑配置文件，允许所有ip访问：
[php]
$ vim squid.conf
http_port 3228 # 修改端口，默认为 3128
http_access allow all # 添加 ，为允许所有ip
[/php]
保存后可以检查配置文件是否有误：
[php]squid -k parse #配置文件解析日志中，没有出现ERROR 就没有问题[/php]
6. 重启squid服务
[php]systemctl restart squid[/php]
查看监听端口
[php]netstat -lnpt[/php]
如果有出现squid的监听端口就正常了
