/etc/init.d/Standalone Service name Start|stop|status|restart
Service Standalone name Start|stop|status|restart

Chkconfig [--level runlevel, default 2345] [standalone service] [On|off]
Example: Chkconfig--level 2345 mysqld on
Modify the/etc/rc.d/rc.local file (recommended)
Managing self-booting using the NTSYSV command
2. Based on xinetd service
A.yum Installing xinetd with Telnet
B. Managing Telnet through xinetd
Note: Start-up and self-start are connected
(2) Management of source package service
1. Start
Use absolute path:/usr/local/apache/bin/apachectl start|stop
