Centos服务器搭建Squid Http代理请求服务器教程

yum install squid -y
yum install httpd-tools -y

mkdir /etc/squid3/
#这里密码是 ceshi 
htpasswd -cd /etc/squid3/passwords ceshi
#回车 自己输入密码

/usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
#输入账号跟密码
ceshi 123456
#提示 ok 代表正确
ok

vim /etc/squid/squid.conf

# 在最后添加

auth_param basic program /usr/lib64/squid/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth required
http_access allow authenticated

# 这里是端口号，可以按需修改
# http_port 3128 这样写会同时监听ipv6和ipv4的端口，推荐适应下面的配置方法。
http_port 0.0.0.0:3128

# 开启启动
systemctl enable squid.service
# 启动
systemctl start squid.service
# 停止
systemctl stop squid.service
# 重启
systemctl restart squid.service
