在代理端
vi /etc/httpd/conf/httpd.conf
ProxyPass / http://192.168.1.142
ProxyPassReverse / http://192.168.1.142
去访问192.168.1.148.。就可以到192.168.1.142
*******************************************************************************************
负载均衡实现
使用三个服务器两个源站。一个代理142，144 为源站，148为代理
在代理写
vi /etc/httpd/conf/httpd.conf
ProxyRequests off
ProxyPass / balancer://mycluster/
ProxyPassReverse / balancer://mycluster/
<Proxy balancer://mycluster>
ProxySet lbmethod=byrequests
BalancerMember http://192.168.1.142 loadfactor=1 smax=5 max=20 ttl=120 retry=300 timeout=15
BalancerMember http://192.168.1.144 loadfactor=1 smax=5 max=20 ttl=120 retry=300 timeout=15
</Proxy>
systemctl restart httpd.service
源站写
systemctl restart httpd.service
访问148.。。可看到144和142 内容哦
