centons 6.2_x64 搭建 jdk1.7+tomcat7

 实验步骤：
下载所需的两个文件包jdk和tomcat：
apache-tomcat-7.0.29.tar.gz
jdk-7-linux-x64.rpm


删除系统自带的jdk

yum -y remove java

安装jdk1.70

rpm -ivh jdk-7-linux-x64.rpm

安装完成后在新建软连接：

cd /usr/java/
 ln -s /usr/java/jdk1.7.0/ /usr/java/jdk

安装tomcat 7

tar xf apache-tomcat-7.0.29.tar.gz
mv apache-tomcat-7.0.29 /usr/local/tomcat7

增加全局变量到/etc/profile

export JAVA_HOME=/usr/java/jdk
export JRE_HOME=/usr/java/jdk/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export TOMCAT_HOME=/usr/local/tomcat7
export CATALINA_HOME=/usr/local/tomcat7
export PATH=$PATH:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:$JAVA_HOME/bin

应用全局变量：

source /etc/profile

编写服务脚本/etc/init.d/tomcat：

#!/bin/bash
#service tomcat by xzr
source /etc/init.d/functions
source /etc/profile
tomcatbin=/usr/local/tomcat7/bin
case $1 in
        start)
                action "start" $tomcatbin/startup.sh
        ;;
        stop)
                action "stop" $tomcatbin/shutdown.sh
        ;;
        restart)
                action "stop" $tomcatbin/shutdown.sh
                action "start" $tomcatbin/startup.sh
        ;;
        *)
esac

修改/usr/local/tomcat/conf/tomcat-users.xml文件增加管理员帐号：
在</tomcat-users>字段上面增加一句

<user username="xzr" password="xzr" roles="manager-gui"/>

启动tomcat

service tomcat start

浏览：http://localhost:8080
测试代码：

<%@page language="java" import="java.util.*" %>
this is server 10 !!Now, the time&date is: <%out.println(new Date());
out.println("<br>X-Real-IP : " + request.getHeader("X-Real-IP") + "<br>");
%>
