设置静态IP，网络服务将不再启动

  • 772

nmtui edit我使用（编辑的有线连接 1）为我的 CentOS 7 服务器设置了一个静态 IP ：

在此处输入图像描述

现在网络服务 ( systemctl restart network) 不再启动。

日志输出：

有什么我想念的吗？该硬件只有一个连接到它的以太网。

命令输出nmcli -p dev：

nmcli -p dev

    日志显示 enp0s25 和 eth0，它们都不会显示在您的 nmcli 列表中。你确定你编辑的连接是正确的吗？

    我不会搞乱编辑内核参数，而是会追查并修复名称错误的原因。

    /etc/sysconfig/network-scripts 文件的名称和内容是否正确？名称应与您的接口相对应：ifcfg-enp12s0 和 DEVICE=enp12s0。如果没有其他东西看起来不合适systemctl restart NetworkManager并检查。

    在我的 Centos 7 服务器文件名上，DEVICE=、nmcli 和 nmtui 都显示相同的内容 - 你不应该只有一个网卡有 3 个条目。我会删除 2 并修复一个。也许您更改了导致 Centos 重命名的网卡或 bios 设置。其他 2 个通用条目可能是无意中添加的。

  2. 看起来您正在尝试启动eth0，但您的设备名称是enp12s0。

    您可以biosdevname=0 net.ifnames=0在内核命令行上设置旧的 NIC 名称。
