tomcat部署

web服务器：
websphere:IBM
weblogic:BEA，被Oracle收购
oc4j:Oracle收
JBoss:RedHat

Sun-->Tws(记不清了)
    RI:Reference Implimentation
    参考实现
    
    ASF:Apache Software Foundation
        Jserv
        
    Sun-->ASF（贡献给ASF）
    catalina(代码名称)
        O'Reilly:Tomcat（程序名称）
下载tomcat
解压：
catalina.sh start/stop
可以编写service脚本：
tomcat.sh

A Tomcat init script for Linux
#!/bin/sh
# Tomcat init script for Linux.
#
# chkconfig: 2345 96 14
# description: The Apache Tomcat servlet/JSP container.
JAVA_HOME=/usr/java/jdk1.7.0_05
CATALINA_HOME=/opt/apache-tomcat-7.0.29
export JAVA_HOME CATALINA_HOME
exec $CATALINA_HOME/bin/catalina.sh $*

export:定义变量，文件位置不同作用域不同，/etc/profile等文件中配置全局环境变量，全局有效
        普通文件中定义，只在当前shell进程中有效
exec:shell中执行指定的命令
     终端中执行命令后退出终端

修改文件执行权限：chmod +x stop.sh
chkconfig --add tomcat(删除：chkconfig --del tomcat)
chkconfig --list tomcat
如果：2 3 4 5状态为on，说明开启了开机自启动
可以执行service tomcat start
        service tomcat stop
        这里要看catalina.sh -help中有哪些命令，则参数可以传哪些命令，如start，stop，...，注意：没有restart
配置开机自启动：
chkconfig tomcat on
chkconfig tomcat off

完整tomcat启动脚本：
