Controlling Service

1. #system-config-services (圖形介面)
2. #ntsysv(文字介面)
可以控制service是否在開機要啟動


3. service httpd [start|stop|restart|status]
手動啟動,停止, 重新啟動, 狀態

4. chkconfig httpd [on|off]
以命令的方式決定開機時是否啟動

5. chkconfig --list [service-name]

[root@server1 ~]# chkconfig --list xinetd
xinetd 0:off 1:off 2:off 3:on 4:on 5:on 6:off

列出所有執行服務狀態, 不指定服務列出全部服務的狀態
