服务器中服务众多，每次重启服务器、或者服务器宕机。都需要重新启动服务，费时耗力。因此想到将所有的服务全部干成系统服务，并开机自启。

以下操作均在centos6中进行

整体流程如下：

1. 编写启动脚本

2.将脚本设置为系统服务

chkconfig --add script_name
chkconfig script_name on

3.验证是否已开机自启

chkconfig --list script_name
script_name          0:off  1:off   2:on    3:on    4:on    5:on    6:off

0-6代表启动7种运行级别，脚本中可设置

以上内容网络上很多，也更加详细，各位有兴趣可自行网上查阅。
