redhat linux默认运行级别有哪些

Ubuntu的默认开机的runlevel是2,可以用runlevel来查看当前的默认运行级别。 debian系(ubuntu是基于debian)的Linux一直是用runlevel 2来默认启动，并且runlevel定义也与redhat有区别。 debian的runlevel级别定义如下: 0 - Halt 1 - Single 2 - Full multi-user with display manager (GUI) 3 - Full multi-user with display manager (GUI) 4 - Full multi-user with display manager (GUI) 5 - Full multi-user with display manager (GUI) 6 - Reboot 可以发现2~5级是没有任何区别的。 而redhat的runlevel级别定义如下: 0 - Halt 1 - Single 2 - Not used/User definable 3 - Full multi-user NO display manager 4 - Not used/User definable 5 - Full multi-user with display manager (GUI) 6 - Reboot
