启动脚本

启动脚本示例 https://github.com/cyclops26/service-scripts/blob/master/genericServiceScript

#!/bin/bash
#
# APPLICATION_NAME      This shell script takes care of starting and stopping APPLICATION_NAME

# chkconfig: - 80 20

centos/redhat使用chkconfig管理系统服务
1）将启动脚本拷贝到/etc/init.d目录下，假设脚本名称为 my-script

2）添加自己的系统服务
# chkconfig --add my-script

3）修改系统服务在不同level下的开关状态
# chkconfig  [--level [123456] ]  [服务名]  [on | off]

4）查看服务
 # chkconfig --list  [服务名]
