centos8如何重启网卡
1、查看系统
[root@centos8pc2 network-scripts]# hostnamectl Static hostname: centos8pc2 Icon name: computer-vm Chassis: vm Machine ID: f021cde3a91b4a2688dbedfe0884e052 Boot ID: ffbe1ee973aa4d44a7b8b9d1a58683f1 Virtualization: vmware Operating System: CentOS Linux 8 CPE OS Name: cpe:/o:centos:centos:8 Kernel: Linux 4.18.0-240.el8.x86_64 Architecture: x86-64
2、修该网卡配置文件(自定义一个ip地址,然后重启网卡使其生效)
[root@centos8pc2 network-scripts]# vim /etc/sysconfig/network-scripts/ifcfg-ens160 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens160 UUID=77656063-2595-411d-8b36-49caab425c3e DEVICE=ens160 ONBOOT=yes IPADDR=192.168.3.10 NETMASK=255.255.255.0 GATEWAY=192.168.3.1 DNS1=119.29.29.29
3、重启网卡
[root@centos8pc2 network-scripts]# ifconfig | head -n 3 ens160: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.3.91 netmask 255.255.255.0 broadcast 192.168.3.255 inet6 fe80::c0fe:36f:3a46:9188 prefixlen 64 scopeid 0x20<link> [root@centos8pc2 network-scripts]# systemctl restart network Failed to restart network.service: Unit network.service not found.
