手写tomcat开机自启脚本

[root@localhost ~]$ chkconfig --list                 # 列出所有被chkconfig管理的服务
[root@localhost ~]$ chkconfig --add httpd            # 添加指定的服务，让chkconfig指令管理它
[root@localhost ~]$ chkconfig --del httpd            # 删除指定的服务，不再让chkconfig指令管理它
[root@localhost ~]$ chkconfig httpd on               # 设置开机运行服务，需要先执行 --add 才能执行该命令
[root@localhost ~]$ chkconfig httpd off              # 设置开机不运行服务，需要先执行 --add 才能执行该命令
[root@localhost ~]$ chkconfig --level 35 httpd on    # 设置服务在等级3和5时开机运行服务，默认是设置2345等级开机运行服务
