• CentOS 停止网络服务，输入命令：systemctl stop network.service，或 systemctl stop network。

2. centos重启命令

root下执行reboot或者shutdown -r now
如果是生产环境不要随便重启。
网上找到的命令建议自己先在虚拟机上测试，不要随便用，比如某个坑人的回答的rm -rf / 执行后会导致系统挂掉。

3. 懂linux 进，CentOS7.3设置定时重启的命令是什么

用root用户登录系统

7. centos7 怎么重启网络配置

1.首先找到网关：

打开虚拟机，“编辑”-“虚拟网络编辑器”，即可看到各个信息

(7)centos重启命令扩展阅读：

CentOS（Community Enterprise Operating System，中文意思是：社区企业操作系统）是Linux发行版之一，它是来自于Red Hat Enterprise Linux依照开放源代码规定释出的源代码所编译而成。由于出自同样的源代码，因此有些要求高度稳定性的服务器以CentOS替代商业版的Red HatEnterprise Linux使用。两者的不同，在于CentOS并不包含封闭源代码软件

8. 如何centos 系统反复重启命令

用root用户登录系统 crontab -e #创建计划任务 按i进入输入模式，添加如下行 01 2 * * * reboot #该行表示每天2：01重启机器
