CentOS 网络接口未启动

CentOS 网络接口未启动

我们在“HP Proliant DL380p Gen8”上安装了 CentOS 的新副本,以太网接口出现了这种奇怪的、波动的连接问题,接口要么正常工作,要么完全死机。

以下是一些命令的输出:

答案1

Centos 通常会禁用网络,除非您在安装时手动启用。如果您的物理网络链路连接正常,您可以使用ip link命令检查链路。您可以在以下路径中找到的每个接口配置中ONBOOT=no设置线路。ONBOOT=yes

/etc/sysconfig/network-scripts/ifcfg-xxxx

nmcli c如果这是较新的 centos 7.x,您可以通过键入命令来获取更多信息

答案2

重命名接口文件名。

mv ifcfg-en01 ifcfg-eno1
