为Apache2.2添加mod_proxy模块:
先找到apache源码中modules/proxy目录并进入，然后使用bin/apxs进行编译安装。这里只是提供了安装扩展模块的方法，在实际安装过程中并没有执行，因为上面的安装过程已经安装了负载均衡的代理模块。
[root@apachehs~]#cd/usr/local/src/httpd-2.2.31/modules/proxy
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy.cproxy_util.c
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy_ajp.cajp*.c
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy_balancer.c
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy_connect.c
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy_http.c
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy_ftp.c
[root@apachehsproxy]#/usr/local/apache/bin/apxs-c-i-amod_proxy_scgi.c
-c表示进行编译，-i表示将生成的模块安装到apache的modules目录下，-a选项在httpd.conf中增加一条LoadModule指令以载入刚安装的模块，或者如
果此指令已存在，则启用之。
apxs会根据源码判断模块的名称，或者（在失败的情况下）根据文件名推测模块名称，可以用-n选项显式地指定模块名称。
安装成功以后将在apache的modules目录下生成mod_proxy.so文件，并且在httpd.conf中加入了一行
下面开始配置ApacheHttpServer
[root@apachehshome]#vihttpd.conf
LoadModuleproxy_modulemodules/mod_proxy.so
LoadModuleproxy_ajp_modulemodules/mod_proxy_ajp.so
LoadModuleproxy_balancer_modulemodules/mod_proxy_balancer.so

#Virtualhosts

找到#ServerName...一行，在下面添加

在文件的最后加上如下几行:
