Squid

1.Squid正向代理

 

【真机】

[root@foundation66 ~]# yum install squid -y

[root@foundation66 ~]# systemctl start squid

 

[root@foundation66 ~]# vim /etc/squid/squid.conf

 56 http_access deny all ------> http_access allow all

 62 #cache_dir ufs /var/spool/squid 100 16 256 ------> cache_dir ufs /var/spool/squid 100 16 256

 

[root@foundation66 ~]# systemctl restart squid

 

【虚拟机】

 

浏览器 -> Edit -> Preferences -> Advanced -> Network -> Settings -> Manual proxy cOnfiguration -> HTTP Proxy 172.25.254.29 Port 3128 -> OK

 

2.Squid反向代理加速

 

1）单代理

 

【无apache虚拟机】

 

[root@localhost ~]# yum install squid -y

[root@localhost ~]# systemctl start squid

 

[root@localhost ~]# vim /etc/squid/squid.conf

 56 http_access deny all ------> http_access allow all

 59 http_port 3128 ------> http_port 80 vhost vport

 60 【添加】cache_peer 172.25.254.129 parent 80 0 no-query

 62 #cache_dir ufs /var/spool/squid 100 16 256 ------> cache_dir ufs /var/spool/squid 100 16 256

 

[root@localhost ~]# systemctl restart squid

 

浏览器访问 172.25.254.229

 

2）多代理

 

【轮叫】

 

[root@localhost ~]# vim /etc/squid/squid.conf

 56 http_access deny all ------> http_access allow all

 59 http_port 3128 ------> http_port 80 vhost vport

 60 【添加】cache_peer 172.25.254.129 parent 80 0 no-query originserver name=route1 round-robin weight=3

 61 【添加】cache_peer 172.25.254.66 parent 80 0 no-query originserver name=route2 round-robin weight=1

 62 【添加】cache_peer_domain www.westos.com route1 route2

 64 #cache_dir ufs /var/spool/squid 100 16 256 ------> cache_dir ufs /var/spool/squid 100 16 256

 

##no-query 不查询  

##originserver当父级节点为route1时做加速

##round-robin检测轮叫次数（超过限制转向下一个代理）

##weight= 轮叫限制

 

[root@localhost ~]# systemctl restart squid
