电脑环境:  windows 7, 64.

软件版本:  Apache http 2.2, tomcat-8.0.15, JDK jdk1.8.0,

**1. Apache httpd-2.2** 目录 E:\\PHPCMS\\Apache2.2

1.1 打开E:\\PHPCMS\\Apache2.2\\conf\\httpd.conf去掉以下文本前的注释符(\#)以便让Apache在启动时自动加载代理(proxy)模块

LoadModule proxy_module modules/mod_proxy.so
    
    LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
    
    LoadModule slotmem_module modules/mod_slotmem.so
    
    LoadModule manager_module modules/mod_manager.so
    
    LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
    
    LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
    
    LoadModule proxy_connect_module modules/mod_proxy_connect.so
    
    LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
    
    LoadModule proxy_http_module modules/mod_proxy_http.so

1.2 在下列节点中增加index.jsp , 目的是能看到首页（conf/httpd.conf文件）

#
    # DirectoryIndex: sets the file that Apache will serve if a directory
    # is requested.
    #
    <IfModule dir_module>
        DirectoryIndex index.php default.php index.html index.htm index.jsp default.jsp
    </IfModule>
    
    #开启虚拟站点配置
    #去掉Include/ conf/extra/httpd-vhosts.conf前面的注释（conf/httpd.conf文件）
    # Virtual hosts
    Include conf/extra/httpd-vhosts.conf

1.3 配置反向代理 tomcat.  
  
   说明 Tomcat 的webapps 路径: E:\\WebServer\\apache-tomcat-8.0.15\\webapps.  经过webapps.war 释放，有 aerchi-dev目录，  如下图

在E:\\PHPCMS\\Apache2.2\\conf\\extra\\httpd-vhosts.conf，配置虚拟站点，在下面加上

<VirtualHost *:80>
        ServerName localhost
        ServerAlias localhost
    
        <Proxy *>
            Order deny,allow
            Allow from all
        </Proxy>
    
        #OK 2019-05-08
    #    <Proxy balancer://cluster>
    #        BalancerMember http://192.168.128.99:8080 route=server1
    #        ProxySet stickysession=ROUTEID
    #    </Proxy>
    #    ProxyPass /aerchi-dev/luxiren balancer://cluster/aerchi-dev/luxiren 
    
    
        <Proxy balancer://cluster>
            BalancerMember http://192.168.128.99:8080 route=server1
            ProxySet maxattempts=30
            ProxySet nofailover=On
            ProxySet timeout=600
            ProxySet stickysession=StickyCookie
            ProxySet lbmethod=byrequests
            ProxySet stickysession=ROUTEID
        </Proxy>
    
        ProxyPreserveHost On
    
        ProxyPass /aerchi-dev/luxiren  balancer://cluster/aerchi-dev/luxiren stickysession=JSESSIONID|jsessionid nofailover=Off
        ProxyPassReverse /aerchi-dev/luxiren balancer://cluster/aerchi-dev/luxiren 
    
    
        #Please add vt proxy if use sub context
        #vt
        ProxyPass /aerchi-dev/vt balancer://cluster/aerchi-dev/vt stickysession=JSESSIONID|jsessionid nofailover=Off
        ProxyPassReverse /cumbria-dev/vt balancer://cluster/aerchi-dev/vt
    
        ErrorLog "logs/luxiren -error.log"
        CustomLog "logs/luxiren -access.log" common
    </VirtualHost>

2. Tomcat 配置，在 Tomcat E:\\WebServer\\apache-tomcat-8.0.15\\conf\\server.xml 里进行如下修改:  
Tomcat目录: E:\\WebServer\\apache-tomcat-8.0.15

<Engine name="Catalina" defaultHost="localhost" jvmRoute="server1">

Tomcat 运行 Server

关闭: shutdown.bat  
启动: startup.bat
