Apache-mod-proxy-balancer

要启用负载均衡, 除了要加载 mod_proxy 和 mod_proxy_balancer 以外, 还要至少加载一个 balancing scheduler algorithm 模块:

• mod_lbmethod_byrequests
• mod_lbmethod_bytraffic
• mod_lbmethod_bybusyness
• mod_lbmethod_heartbeat

示例:

<Proxy "balancer://mycluster">
    BalancerMember "http://192.168.1.50:80" route=backend1 loadfactor=1
    BalancerMember "http://192.168.1.51:80" route=backend2 loadfactor=2
</Proxy>
ProxyPass        "/test" "balancer://mycluster"
ProxyPassReverse "/test" "balancer://mycluster"
