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=tomcat #tomcat启动用户，需要shell权限

##################

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=/usr/java/jdk1.7.0_80

#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=tomcat

#TOMCAT_USAGE is the message if this script is called without any options
TOMCAT_USAGE="Usage: $0 {e[00;32mstarte[00m|e[00;31mstope[00m|e[00;32mstatuse[00m|e[00;31mrestarte[00m}"

#SHUTDOWN_WAIT is wait time in seconds for java proccess to stop
SHUTDOWN_WAIT=20
