tomcat多功能启动脚本
tomcat bin目录下已经有了启动、关闭的脚本，写这个脚本主要是为了方便自动化运维，把tomcat和jdk推到服务器上解压后，把这个脚本传到PATH目录下，改个名字，给个执行权限就可以了，可以少设置很多东西，同时功能更加丰富。主要有以下几点功能：
- 只需配置JDK目录和tomcat目录即可，无需设置全局JDK环境变量和setenv.sh
- 可以指定tomcat启动运行的用户
- 系统中有多个tomcat时，可以公用一个脚本
- 每次启动tomcat都会先检查目录权限和清理临时目录，并调整ulimit，防止应用使用缓存和出现性能问题
- 可以查看tomcat运行详细情况，cpu/内存/RSS/VSZ/运行时间等
- 可以使用本脚本tail输出 catalina.out
- 安全停止tomcat，先正常关闭tomcat,等待一段时间后kill，确保tomcat能够关闭
- 可以在tomcat关闭时，清理缓存目录temp/webapp/work
- tomcat运行时，可以使用jinfo/jmap/jstack导出jvm信息
都在脚本里，详细的自己看脚本吧。可以实现tomcat start/stop/status/kill/tail/clean/dump等功能。

#tomcat install dir
export CATALINA_HOME=/opt/tomcat-9.0_blog/
#TOMCAT_USER is the default user of tomcat
export TOMCAT_USER=tomcat
#SHUTDOWN_WAIT is wait time in seconds for java proccess to stop
SHUTDOWN_WAIT=5
# add java JDK path
export JAVA_HOME=/opt/jdk1.8

#####以上是按需修改的地方######
#TOMCAT_USAGE is the message if this script is called without any options
TOMCAT_USAGE="用法: $0 {\e[00;32mstart\e[00m|\e[00;31mstop\e[00m|\e[00;31mkill\e[00m|\e[00;32mstatus\e[00m|\e[00;31mrestart\e[00m|\e[00;32mtail\e[00m|\e[00;32mclean|\e[00;31mdump\e[00m}\n\
参数模式: $0 {\e[00;32m[action] \e[00;31m[tomcat path] \e[00;31m[run user] \e[00m} \n\n
启动参数说明： \n
start: 启动tomcat \n
stop: 正常停止tomcat \n
kill: 杀掉tomcat进程 \n
status: 查看状态,是否运行/详细的运行状态 \n
restart: 调用stop/start重启tomcat \n
tail: 使用tail命令查看catalina.out日志 \n
clean: tomcat关闭时，清理缓存目录temp/webapp/work \n
dump: 使用jinfo/jmap/jstack导出jvm信息 \n\n
参数模式主要供脚本调用，或者多个tomcat公用一个init脚本;CATALINA_HOME和TOMCAT_USER通过参数传入，脚本中无需指定,使用方法： \n
$0 启动参数 tomcat路径 运行用户 \n
$0 status /opt/tomcat8/ tomcat \n
