linux运维-squid

1.squid正向代理
    在真机进行操作：
    yum install squid -y

    vim /etc/squid/squid.conf
        ##acl badurl dst www.baidu.com      ##访问不到www.baidu.com其他可以
        ##acl badurl dstdomain .baidu.com   ##所有的.baidu.com都访问不到
        ##http_access deny badurl       ##拒绝做badurl的代理
        http_access allow localnet      ##允许本机网络访问
        http_access allow localhost     ##允许本地主机访问

        # And finally deny all otheraccess to this proxy
        http_access allow all                           ##允许所有人通过http访问

        # Squid normally listens to port3128
        http_port 3128                              ##端口号为3128

        # Uncomment and adjust thefollowing to add a disk cache directory.
        cache_dir ufs /var/spool/squid 10016 256               ##访问缓存
        systemctl restart squid

   

测试：desktop
    firefox->edit->preferences->advanced->network->setting->manual:http:172.25.254.22port:3128

       
2.squid反向代理
    server:(关闭httpd服务）
    yum install squid -y

    vim /etc/squid/squid.conf
        http_access allow all
        cache_peer 172.25.254.122 parent80 0 no-query
        # Squid normally listens to port3128
        http_port 80 vhost vport
         
        # Uncomment and adjust thefollowing to add a disk cache directory.
        cache_dir ufs /var/spool/squid 10016 256

    systemctl restart squid
    测试：浏览器输入172.25.254.122可以访问到

\

3.squid访问多台服务器
    server:
    vim /etc/squid/squid.conf
        http_access allow all
        # Squid normally listens to port3128
        http_port 80 vhost vport
        cache_peer 172.25.254.122 parent80 0 no-query originserver name=web1 round-robin
        cache_peer 172.25.254.122 parent80 0 no-query originserver name=web2 round-robin
        cache_peer_domain www.westos.comweb1 web2
         
        # Uncomment and adjust thefollowing to add a disk cache directory.
        cache_dir ufs /var/spool/squid 10016 256

   

systemctl restart squid
    vim /etc/hosts
