CentOS7.5 新装系统如何查看网络，配置网卡信息

1.查看ip信息
ip a

ip a1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:50:56:25:19:1c brd ff:ff:ff:ff:ff:ff inet 192.168.1.227/24 brd 192.168.1.255 scope global noprefixroute ens33 valid_lft forever preferred_lft forever inet6 fe80::36fd:c3d4:ea0a:5ab4/64 scope link noprefixroute valid_lft forever preferred_lft forever

2.查看编辑网卡信息

vim /etc/sysconfig/network-scripts/ifcfg-ens33（网卡名）

TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=noneDEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6INIT=yesIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_FAILURE_FATAL=noIPV6_ADDR_GEN_MODE=stable-privacyNAME=ens33UUID=bf5bb7c5-da27-44a9-b4be-7f6e4138abfdDEVICE=ens33ONBOOT=yesIPADDR=192.168.1.227PREFIX=24GATEWAY=192.168.1.1

重启网络服务
systemctl restart network

查看ens33网卡信息
ifconfig ens33

ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.227 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::36fd:c3d4:ea0a:5ab4 prefixlen 64 scopeid 0x20<link> ether 00:50:56:25:19:1c txqueuelen 1000 (Ethernet) RX packets 29155875 bytes 2426699185 (2.2 GiB) RX errors 0 dropped 108161 overruns 0 frame 0 TX packets 32605674 bytes 12952561612 (12.0 GiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

启用ens33网卡
ifconfig ens33 up

禁用ens33网卡
ifconfig ens33 down
