Apache Mod_proxy 模块

编译安装启用Proxy模块：

 

 

 

tar httpd-2.2.15.tar.gz

cd httpd-2.2.15

./configure --prefix=/usr/local/apache --enable-proxy --enable-proxy-connect --enable-proxy-http --enable-proxy-balancer

make –j 2

make install

 

 

 

修改Apache主配置文件：

 

 

 

# 检查有没编译进去proxy相关的模块：/usr/local/apache/bin/apachectl -l

 

# 在配置文件最后加入：vim /usr/local/apache/conf/httpd.conf

 

ProxyRequests Off

ProxyPass / balancer://cluster

BalancerMember loadfactor=1 route=jvm1

BalancerMember loadfactor=9 route=jvm2

 

 

 

其它配置示例：

 

 

1：将指定子目录分配不同的Server端：

 

ProxyRequests Off

proxypass /news  

proxypass /it   

 

 

2：会话保持 (session_stick) ：

 

ProxyRequests Off
ProxyPass /test   balancer://cluster stickysession=jsessionid nofailover=On

BalancerMember loadfactor=1
BalancerMember loadfactor=1

 

 

3：按流量分配负载并指定热备:

 

ProxyRequests Off
ProxyPass /test   balancer://cluster

BalancerMember loadfactor=1

BalancerMember loadfactor=1

BalancerMember loadfactor=1 status=+H

ProxySet lbmethod=bytraffic

 

 

4：状态查看，需编译mod_status模块:

 

ProxyRequests Off

ProxyPass /test   balancer://cluster stickysession=jsessionid nofailover=On

BalancerMember loadfactor=1
BalancerMember loadfactor=1
