Linux中重启的两个命令:reboot和init 6之间的区别
- font size decrease font size increase font size
init命令用于改变操作系统的运行级别。
Init 6是重新启动机器。
reboot也是重新启动机器。
那么这两个命令到底有什么区别呢?
对这两个操作使用man命令看到的内容如下:
"init 6" 基于一系列/etc/inittab文件,并且每个应用都会有一个相应shutdown脚本。
'init 6' 调用一系列shutdown脚本(/etc/rc0.d/K*)来使系统优雅关机;
'reboot'并不执行这些过程,reboot更是一个kernel级别的命令,不对应用使用shutdown脚本。 .
我们应该在通常情况下使用 init 6.
reboot - reboot performs a sync(1M) operation on the disks, and then a
multi- user reboot is initiated. See init(1M) for details.
init 6 Stop the operating system and reboot to the
state defined by the initdefault entry in
/etc/inittab.
在出问题的状况下或强制重启时使用reboot.
