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：
- 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。
