CentOS5/6的启动流程centos
启动流程画了张图,看着更清晰些: (centos7的启动流程变化挺大的,这部分待补充)bash
补充(/etc/rc.d/rc.local 不属于任何服务,为特殊文件,可将不能定义为服务又想开机运行的命令定义在此文件中)ide
添加自定义服务:centos7
[root@el5 init.d]# vi /etc/init.d/testsrv spa #!/bin/bashblog #chkconfig: 223 92 60ip #description: programs at periodic scheduled times. vixie cron adds a \it # number of features to the basic UNIX cron, including better \io # security and more powerful configuration options.#table echo "hello"
[root@el5 init.d]# chkconfig --add testsrv
[root@el5 init.d]# service testsrv hello |
