IPMI配置网络，有两种方式： ipmi over lan（大体意思是通过网卡来进行连接） 独立 （给服务器单独插一个网线） DELL服务器可以在小面板中设置ipmi 云主机我们不需要考虑IPMI
[q] [c] [C] [S] [n] 运维必会！ 参数说明 d指定每两次屏幕信息刷新之间的时间间隔。当然用户可以使用s交互命令来改变之。 p通过指定监控进程ID来仅仅监控某个进程的状态。 q该选项将使top没有任何延迟的进行刷新。如果调用程序有超级用户权限，那么top将以尽可能高的优先级运行。 S指定累计模式。 s使top命令在安全模式中运行。这将去除交互命令所带来的潜在危险。 i使top不显示任何闲置或者僵死进程。 c显示整个命令行而不只是显示命令名。 下面介绍在top命令执行过程中可以使用的一些交互命令 从使用角度来看，熟练的掌握这些命令比掌握选项还重要一些。 这些命令都是单字母的，如果在命令行选项中使用了s选项，则可能其中一些命令会被屏蔽掉。 Ctrl+L 擦除并且重写屏幕。 h或者? 显示帮助画面，给出一些简短的命令总结说明。 k 终止一个进程。系统将提示用户输入需要终止的进程PID，以及需要发送给该进程什么样的信号。一般的终止进程可以使用15信号；如果不能正常结束那就使用信号9强制结束该进程。默认值是信号15。在安全模式中此命令被屏蔽。 i 忽略闲置和僵死进程。这是一个开关式命令。 q 退出程序。 r 重新安排一个进程的优先级别。系统提示用户输入需要改变的进程PID以及需要设置的进程优先级值。输入一个正值将使优先级降低，反之则可以使该进程拥有更高的优先权。默认值是10。 s 改变两次刷新之间的延迟时间。系统将提示用户输入新的时间，单位为s。如果有小数，就换算成m s。输入0值则系统将不断刷新，默认值是5 s。需要注意的是如果设置太小的时间，很可能会引起不断刷新，从而根本来不及看清显示的情况，而且系统负载也会大大增加。 f或者F 从当前显示中添加或者删除项目。 o或者O 改变显示项目的顺序。 l 切换显示平均负载和启动时间信息。 m 切换显示内存信息。 t 切换显示进程和CPU状态信息。 c 切换显示命令名称和完整命令行。 M 根据驻留内存大小进行排序。 P 根据CPU使用百分比大小进行排序。 T 根据时间/累计时间进行排序。 W 将当前设置写入~/.toprc文件中。这是写top配置文件的推荐方法。 Shift+M 可按内存占用情况进行排序。
