实验环境
- Apache 192.168.200.101
- Tomcat1 192.168.200.102
- Tomcat2 192.168.200.103
一、安装tomcat1
（1）解压jdk
tar xf jdk-7u65-linux-x64.gz
mv jdk1.7.0_65 /usr/local/java
（2）配置环境变量
vim /etc/profile.d/java.sh #添加以下内容
export JAVA_HOME=/usr/local/java #设置java的根目录
export PATH=$PATH:$JAVA_HOME/bin
（3）生效脚本
source /etc/profile.d/java.sh
（4）安装tomcat
tar xf apache-tomcat-7.0.54.tar.gz
mv apache-tomcat-7.0.54 /usr/local/tomcat7
mkdir -p /webapp
cd /webapp
vim index.jsp // 设置默认网页，新建jsp页面并添加以下内容
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title> JSP test1 page</title>
</head>
<body>
<% out .println("welcom to test sits,http://www.text1.com");%>
</body>
</html>
编辑主配置文件
vim /usr/local/tomcat7/conf/server.xml #在130行下添加以下红色部分内容
128 <Host name="localhost" appBase="webapps"
129 unpackWARs="true" autoDeploy="true"
130 xmlValidation="false" xmlNamespaceAware="false">
<Context docBase="/webapp" path="" reloadable="false" >
</Context>
启动tomcat
/usr/local/tomcat7/bin/startup.sh
二、安装tomcat2
（1）解压jdk
tar xf jdk-7u65-linux-x64.gz
mv jdk1.7.0_65 /usr/local/java
（2）配置环境变量
vim /etc/profile.d/java.sh #添加以下内容
export JAVA_HOME=/usr/local/java #设置java的根目录
export PATH=$PATH:$JAVA_HOME/bin
（3）生效脚本
source /etc/profile.d/java.sh
（4）安装tomcat
tar xf apache-tomcat-7.0.54.tar.gz
mv apache-tomcat-7.0.54 /usr/local/tomcat7
mkdir -p /webapp
cd /webapp
vim index.jsp #设置默认网页，新建jsp页面并添加以下内容
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title> JSP test2 page</title>
</head>
<body>
<% out .println("welcom to test sits,http://www.text2.com");%>
</body>
</html>
编辑主配置文件
vim /usr/local/tomcat7/conf/server.xml #在130行下添加以下红色部分内容
128 <Host name="localhost" appBase="webapps"
129 unpackWARs="true" autoDeploy="true"
130 xmlValidation="false" xmlNamespaceAware="false">
<Context docBase="/webapp" path="" reloadable="false" >
</Context>
启动tomcat
/usr/local/tomcat7/bin/startup.sh
保证tomcat能够正常访问
三、安装apache
tar xf httpd-2.2.17.tar.gz
cd httpd-2.2.17
./configure --prefix=/usr/local/httpd --enable-so --enable-cgi --enable-charset --enable-charset-lite --enable-rewrite --enable-proxy --enable-proxy-http --enable-proxy-ajp --enable-proxy-balabcer --enable-lbmenthod-heartbeat --enable-slotmem-shm --enable-slotmem-plain --enable-watchdog
make && make install
ln -s /usr/local/httpd/bin/* /usr/local/bin
cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
vi /etc/init.d/httpd #编辑启动脚本 ，增加红色部分内容
#!/bin/sh
#chkconfig:345 66 88
#description:http apache
chmod +x /etc/init.d/httpd
chkconfig --add httpd
vim /usr/local/httpd/conf/httpd.conf #修改配置文件
// 去掉388行的注释，改为：
Include conf/extra/httpd-vhosts.conf
// 修改虚拟主机配置文件
vim /usr/local/httpd/conf/extra/httpd-vhosts.conf
<VirtualHost *:80>
DocumentRoot /webapp/index.jsp
ServerName CentOS6-node1
ProxyVia Off
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://192.168.200.102:8080/
ProxyPassReverse / http://192.168.200.102:8080/
</VirtualHost>
<VirtualHost *:80>

启动apache
/etc/init.d/httpd start //出现以下warning不用管
Warning: DocumentRoot [/webapp/index.jsp] does not exist
Warning: DocumentRoot [/webapp/index.jsp] does not exist
四、==测试==
使用浏览器访问http://192.168.200.101
刷新轮流出现tomcat1和tomcat2界面如下：
