1, the first page to make distinction

[root@web httpd]# cd /var/www/html/
[root@web html]# ls
[root@web html]# vim index.html
<h1>this is test1 web</h1>

2, based on the previous experiments, to open a server web2: 192.168.247.161

[root@localhost ~]# hostnamectl set-hostname web2
[root@localhost ~]# su
[root@web2 ~]# 
[root@web2 ~]# systemctl stop firewalld
[root@web2 ~]# setenforce 0
[root@web2 ~]# yum install httpd -y
[root@web2 ~]# cd /var/www/html/
[root@web2 html]# vim index.html
<h1>this is test2 web2</h1>
[root@web2 html]# systemctl start httpd
[root@web2 html]# netstat -natp | grep 80
tcp6       0      0 :::80                   :::*                    LISTEN      17713/httpd   
[root@web2 html]# route add -net 192.168.10.0/24 gw 192.168.247.206

3, switching to the squid reverse proxy configuration server 192.168.247.206

[root@squid sarg]# vim /etc/squid.conf
# Squid normally listens to port 3128
http_port 192.168.247.206:80 accel vhost vport      //修改
//下面为增加

cache_peer 192.168.247.161 parent 80 0 no-query orginserver round-robin max_conn=30 weight=1 name=web2

[root@squid sarg]# netstat -natp | grep 80

[root@squid sarg]# systemctl stop httpd             
[root@squid sarg]# netstat -natp | grep 80
[root@squid sarg]# service squid restart
正在关闭 squid...
正在启动 squid...
[root@squid sarg]# netstat -natp | grep 80
tcp        0      0 192.168.247.206:80      0.0.0.0:*               LISTEN  

4, turn off the firewall and enhanced security features

[root@squid sarg]# systemctl stop firewalld
[root@squid sarg]# setenforce 0

5, modify win10 client hosts file, use administer


and access squid
