该脚本改自csdn上的一个shell,忘记出处了,只记得它能够简单的通过service tomcat [stop|start|restart]
来方便的管理Linux服务器上的tomcat,这可以满足大部分人的需求,然而并不适合我所管理的CentOS上的tomcat应用:通过端口区分的3台tomcat集群。如果每一次管理tomcat或查看日志,都cd /apps/test/tomcat0/log/
然后切换到另外一个cd ../../
或cd /apps/test/tomcat1/log/
,麻烦至极。因此“懒人”创造了这个脚本tomcat

使用说明:
1. 使用前设定好baseDir
(多tomcat所在路径),各tomcat命名如tomcat0
、tomcat1
…
2. 脚本名字为tomcat
,放到/etc/init.d/
下,并基于可执行权限chmod +x /etc/init.d/tomcat
3. 执行用户不允许用root
,特别是在线上环境
4. 已处理其他错误参数输入,可用于正式环境
5. 你也可以修改tcName
来适应管理一个tomcat服务的情形
6. 使用,以下针对tomcat0
(/apps/test/tomcat0
)
service tomcat 0 start 启动,默认回车会查看启动日志;已启动则仅输出进程号
service tomcat 0 stop 停止,默认回车会查看日志;已停止则无动作;无法停止,则提示是否`kill`(默认No)
service tomcat 0 restart 重启tomcat,有日志输出
service tomcat 0 status 查看tomcat是否启动
service tomcat 0 log 使用`tail -f`命令实时查看日志
service tomcat 0 kill 直接`kill`tomcat进程;尽量少用
TO-DO
加入service tomcat 0 clean
命令来清除work
和tmp
目录,正在运行的不允许清除。
这个脚本最近(2014/11/13)在使用过程中发现一个新的问题,因为服务器上tomcat一直开启着监控端口7091,所以在service tomcat 1 start
失败以后,7091端口就被占用了,但使用service tomcat 1 status
状态时stopped
,其实还是有这个失败的tomcat进程,但用service tomcat 1 kill
会失败。脚本里在考虑这个功能的话就有点臃肿了,还是老实结合手动管理吧。
