Tomcat启动脚本

记录一个比较好的tomcat启动脚本，截取《OneinStack》，修改如下两个参数即可用。

使用之前修改下面2个参数：

    #Location of JAVA_HOME (bin files)
    export JAVA_HOME=/usr/java/jdk1.7.0_80    #jdk路径
    #CATALINA_HOME is the location of the configuration files of this instance of Tomcat
    CATALINA_HOME=/usr/local/tomcat    #tomcat路径  
    #TOMCAT_USER is the default user of tomcat
    TOMCAT_USER=www    #tomcat启动用户，需要shell权限

tomcat启动、停止、重启，如下图：

脚本内容如下：

    #!/bin/bash  
    #  
    # chkconfig: - 95 15   
    # description: Tomcat start/stop/status script  
      
    #Location of JAVA_HOME (bin files)  
    export JAVA_HOME=  
      
    #Add Java binary files to PATH  
    export PATH=$JAVA_HOME/bin:$PATH  
      
    #CATALINA_HOME is the location of the configuration files of this instance of Tomcat  
    CATALINA_HOME=/usr/local/tomcat  
      
    #TOMCAT_USER is the default user of tomcat  
    TOMCAT_USER=www  
      
    #TOMCAT_USAGE is the message if this script is called without any options  
    TOMCAT_USAGE="Usage: $0 {\e[00;32mstart\e[00m|\e[00;31mstop\e[00m|\e[00;32mstatus\e[00m|\e[00;31mrestart\e[00m}"  
      
    #SHUTDOWN_WAIT is wait time in seconds for java proccess to stop  
    SHUTDOWN_WAIT=20  
      
    tomcat_pid() {  
            echo `ps -ef | grep $CATALINA_HOME | grep -v grep | tr -s " "|cut -d" " -f2`  
    }  
      
    start() {
