1，解压jdk到/usr/local/jdk下
 
2， 解压apache-tomcat到/usr/local/tomcat下
 
3 ，设置环境变量(方法有好几种，只写我用的那种)
     
       将以下三行输入到tomcat目录下startup.sh和shutdown.sh上方
         export JAVA_HOME="/usr/local/jdk"
         export JRE_HOME="/usr/local/jdk"
         export CATALINA_HOME="/usr/local/tomcat"
 
4，启动并验证
      
      /usr/local/tomcat/bin/startup.sh
       curl http://localhost:8080/index.jsp
 
5，apache与tomcat配合： proxy_ajp
   
       在apache配置文件下找proxy_ajp.conf文件，将内容改为：
              LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
              ProxyPass / http://192.168.109.4:8080/
              ProxyPass /tomcat/ http://192.168.109.4:8080/
             ProxyPass /examples/ http://192.168.109.4:8080/jsp-examples/
 
6，设定tomcat与apache共同目录
    
      将   加到以下三句的下一行：
                    unpackWARs="true" autoDeploy="true"
          xmlValidation="false" xmlNamespaceAware="false">
      然后重启apache和tomcat
 
7，设定tomcat的文件访问权限
    
     [root@xxw conf]# cat tomcat-users.xml
     
    
     
      
     
     
     
     
     
    
    
 
8，写一个启动脚本tomcat,放在/etc/init.d目录下，并赋予+x权限
#!/bin/bash
# chkconfig: 2345 10 90
# description: Start and Stop the Tomcat daemon.
TOMCAT_HOME=/usr/local/tomcat
TOMCAT_START=$TOMCAT_HOME/bin/startup.sh
TOMCAT_STOP=$TOMCAT_HOME/bin/shutdown.sh
# necessary environment variables export
CATALINA_HOME=$TOMCAT_HOME
export JAVA_HOME=/usr/java/jdk1.6.0_11
# source function library.
. /etc/rc.d/init.d/functions
# source networking configuration.
. /etc/sysconfig/network
# check that networking is up.
[ "${NETWORKING}" = "no" ] && exit 0
# check for tomcat script
if [ ! -f $TOMCAT_HOME/bin/catalina.sh ]
then echo "Tomcat not valilable..."
exit
fi
start(){
    echo -n "Starting Tomcat: "
    daemon $TOMCAT_START
    echo
    touch /var/lock/subsys/tomcat
}
stop(){
    echo -n $"Shutting down Tomcat: "
    daemon $TOMCAT_STOP
    rm -f /var/lock/subsys/tomcat.pid echo
}
restart(){
    stop
    start
}
status(){
    ps ax --width=1000 | grep "[o]rg.apache.catalina.startup.Bootstrap start" | awk '{printf $1 " "}' | wc | awk '{print $2}' > /tmp/tomcat_process_count.txt
    read line < /tmp/tomcat_process_count.txt
    if [ $line -gt 0 ]; then
        echo -n "tomcat ( pid "
        ps ax --width=1000 | grep "org.apache.catalina.startup.Bootstrap start" | awk '{printf $1 " "}'
        echo -n ") is running..."
        echo
    else
        echo "Tomcat is stopped"
    fi
}
case "$1" in
    start)
        start ;;
    stop)
        stop ;;
    restart)
        stop
        sleep 3
        start ;;
    status)
        status ;;
    *)
    echo "Usage: tomcatd {start|stop|restart|status}"
    exit 1
esac
exit 0

9，排错：503
    
        从外面来看，是服务器无法接受响应了，其实是后台tomcat没响应。可以看看它是否启动，或者apache转发IP和端口是否正确。
       能否实现动静分开，使apache提供静态内容，让tomcat专门解析jsp，亟待研究。
