===== 安装启动 =====

安装命令
<code>
sudo apt update
sudo apt install squid
</code>

启动/关闭服务
<code>
sudo systemctl start squid
sudo systemctl enable squid
sudo systemctl stop squid
# 查看服务情况
sudo systemctl status squid 
</code>

===== 查询 =====

<color #ff7f27>''%%squid -k parse%%''</color> 查看所有的配置情况

查看端口
<code>
ss -tuln | grep squid
netstat -tuln | grep squid
</code>

如果不行的话，
<code shell>
# 查看是否在运行
ps -ef | grep squid
# 查看所有的端口
sudo netstat -tuln
</code>



===== 开通/关闭服务 =====
外网 HTTP

<code>
# http_access deny all
http_access allow all
</code>

端口: 我的服务器开通了3129端口
<code>
http_port 3128
</code>

开通 socks 代理服务
<code >
http_port 3128
http_port 1080 socks
</code>

===== 用户认证 =====
建立密码文档
<code>
sudo apt install apache2-utils
sudo htpasswd -c /etc/squid/passwords <your_squid_username>
</code>

修改config文件

<file >
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
include /etc/squid/conf.d/*
auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
# Example rule allowing access from your local networks.
acl localnet src your_ip_address
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
#http_access allow localnet
http_access allow localhost
http_access allow authenticated
# And finally deny all other access to this proxy
http_access deny all
</file>
===== 测试服务 =====

测试方式
    * curl 命令 <color #ff7f27>''%%curl -v -x http://217.160.61.19:3129 https://google.com%%''</color>
    * nc -v <proxy_ip> <proxy_port> <color #ff7f27>''%%nc -v 217.160.61.19 3129%%''</color> (仅仅测试端口是否开通，如果要看内容，使用上一条测试命令)
    * telnet <proxy_ip> <proxy_port>
    * ++ 当前服务 | http://tonny:T0dayfine1@217.160.61.19:3129 ++  查看 ''serverv2ray::/etc/squid''




第二种方式 <color #ff7f27>''%%curl -x 217.160.61.19:3129 -U "username:passwd" ipinfo.io%%''</color>
