Linux 服务器管理员的12个有用的命令
|
||
================================================================================
|
||
|
||
我们已经读了很多教程和看了很多视频了，你现在是一名Linux高级用户了。好的，恭喜你。但是还有一些需要学习！下面一些命令在你成为全能的管理员时会派上用场！
|
||
|
||
|
||
|
||
1. **ifconfig**: 在修改内核中已有的网络接口时，你会用到ifconfig命令。这个命令通常用于系统调校和调试，但同时也可以用于在启动过程中设置接口。
|
||
|
||
2. **netstat**: 对于Linux用户来说这是一个用于显示网络相关信息的高级命令。它包括路由表、网络连接、伪装连接、接口统计等丰富信息。
|
||
|
||
3. **nslookup**: 在你需要找出关于网络服务的信息时可以用到这个命令。它能帮你找到用于查询DNS域的名称服务器信息。
|
||
|
||
4. **dig**: dig工具用于请求DNS域名服务器。如果你要找出主机地址、邮件交换、名称服务器和其他相关信息，那么这个工具就是最佳选择。你可以在Linux和Mac OS X操作系统上使用这个命令。
|
||
|
||
5. **uptime**: uptime命令用于验证服务器在无人照看下发生了什么。当你需要坐在服务器前查找错误的时候，这个命令尤其有用。
|
||
|
||
6. **wall**: 这个命令用于给所有已登录的用户发送消息。你可以只给那些消息权限设置成了'是'的用户发消息。消息是作为wall命令的参数给出的。
|
||
|
||
7. **mesg**: 用户可以使用'write'命令给你发送消息。但是作为服务器管理员，你可以使用mesg命令来决定他们是否能够使用write命令。你可以选择'n'和'y'，分别用于控制在屏幕上不弹出或者弹出消息。
|
||
|
||
8. **write**: 如果对于一个用户的'mesg'命令的状态设置为'y'，那么write命令就允许你发送消息给那个用户。
|
||
|
||
9. **talk**: 当上面所说的“消息”不够用时，使用talk命令与登陆的用户进行“会话”。
|
||
|
||
10. **w**: 这个命令是uptime和who命令的结合，其显示结果就好像连续先后执行了这两个命令一样。
|
||
|
||
11. **rename**:当你需要重命名特定的文件时，rename命令会派上用场。这个命令可以通过匹配替换来为多个文件批量重命名。
|
||
|
||
12. **top**:这个命令可以显示运行在CPU上的进程。命令会自动刷新并持续显示进程直到你使用中断命令停止它。
