centos6重启命令

CentOS是一款常用的服务器操作系统，尤其在企业级应用中得到广泛使用。在日常使用中，不可避免地会遇到需要重启系统的情况。那么，在CentOS6操作系统下，如何通过命令行进行系统重启呢？下面将为大家介绍具体操作步骤。

首先，使用root账户登录系统。一般情况下，CentOS6的默认登录名为root，密码为用户自行设定。如果是多用户系统，则使用管理员账户登录系统。

进入终端界面，使用以下命令进行系统重启：

```

shutdown -r now

```

其中，`shutdown`表示系统关闭命令，`-r`表示执行重启操作，`now`表示立即执行。此命令执行后，系统会自动关闭并重新启动。

除了使用`now`参数，还可以使用`+m`参数，表示在m分钟后执行重启操作，如：

```

shutdown -r +15

```

上述命令表示在15分钟后重启系统。

如果需要取消重启操作，可以使用`-c`参数，如：

```

shutdown -c

```

上述命令可以取消当前已经排队的重启操作。

除了`shutdown`命令外，还可以使用`reboot`命令进行系统重启，如：

```

reboot

```

上述命令表示立即重启系统。如果希望在m分钟后重启系统，则可以使用`reboot`命令与`sleep`命令相结合，如：

```

sleep 900 && reboot

```

上述命令表示系统会在15分钟后重启。

总之，CentOS6中进行系统重启的命令非常简单，只需要使用`shutdown`或`reboot`命令即可。在使用这些命令时，需要注意确认当前用户具有管理员权限，以避免出现权限不足等问题。

CentOS6 Reboot Command

CentOS is a commonly used server operating system, especially in enterprise-level applications. In daily use, it is inevitable to encounter situations where the system needs to be restarted. So, how to reboot the system through the command line in CentOS6? The following introduces the specific operational steps.

First, log in to the system using the root account. In general, the default login name for CentOS6 is root, and the password is set by the user. If it is a multi-user system, use the administrator account to log in to the system.

Enter the terminal interface and use the following command to restart the system:

```

shutdown -r now

```

Among them, `shutdown` means system shutdown command, `-r` means execute restart operation, and `now` means execute immediately. After the command is executed, the system will automatically shut down and restart.

In addition to using the `now` parameter, the `+m` parameter can also be used, which means to perform the restart operation m minutes later, such as:

```

shutdown -r +15

```

The above command means to restart the system in 15 minutes.

If you need to cancel the restart operation, you can use the `-c` parameter, such as:

```

shutdown -c

```

The above command can cancel the restart operation that is already queued.

In addition to the `shutdown` command, the `reboot` command can also be used to restart the system, such as:

```

reboot

```

The above command means to immediately restart the system. If you want to restart the system in m minutes, you can use the `reboot` command combined with the `sleep` command, such as:

```

sleep 900 && reboot

```

The above command means the system will restart in 15 minutes.

In summary, the command for restarting the system in CentOS6 is very simple, just use the `shutdown` or `reboot` command. When using these commands, it is important to confirm that the current user has administrator privileges to avoid problems such as insufficient permissions.
