1、開啟模組

LoadModule proxy_module modules/mod_proxy.so #proxy模組
LoadModule proxy_connect_module modules/mod_proxy_connect.so #連結的模組
LoadModule proxy_http_module modules/mod_proxy_http.so #給http做代理模組
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so #負載均衡模組
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so
 
 #演算法模組，根據server的請求量
LoadModule lbmethod_bytraffic_module modules/mod_lbmethod_bytraffic.so #演算法模組，根據server流量
LoadModule lbmethod_bybusyness_module modules/mod_lbmethod_bybusyness.so #演算法模組，根據server繁忙程度
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so #

2、配置負載均衡

<VirtualHost *:80> 
       ServerAdmin
 
 [email protected]
       ServerName www.todoliang.cn
       ProxyRequests Off 
       <Proxy *> 
       Options Indexes FollowSymLinks MultiViews
       AllowOverride None
           Order deny,allow 
           Allow from all 
       </Proxy>
    <Proxy balancer://studycluster>
        BalancerMember
 
 http://192.163.1.110/vote/
        BalancerMember http://192.163.1.210/vote/
    </Proxy>

     ProxyPass /demo balancer://studycluster
     ProxyPassReverse /demo balancer://studycluster
</VirtualHost>

3、測試

**linux:**
Apache安裝目錄：bin/apachectl -t

**windows:**
Apache安裝目錄：.\httpd.exe -t

4、重啟即可
