Centos7 设置完固定IP后无法连接网络

出现 Loaded: loaded (/etc/rc.d/init.d/network: bad: vendor preset: disabled) 的异常 按正常流程设置完成固定的 IP 地址后，主机无法连接到网络，观察了一下，连接网线的网口灯也没亮。很奇怪的影响。 执行如下指令查看网络连接状态： systemctl status network 发现在加载 /etc/rc.d/init.d/network 时出现了异常：

network.service - LSB: Bring up/down networking Loaded: loaded (/etc/rc.d/init.d/network: bad: vendor preset: disabled) Active: active (exited) since Thu 2023-04-20 13:38:58 EDT: 1min 3s ago Docs: man:systemd-sysu-generator(B)
