Second, the configuration

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root @ localhost Network-scripts] # LS # 'll see a card configuration profiles
[root @ localhost Network-scripts] # vim the ifcfg-ens33 # into the NIC configuration file
The following profile: bold red is modified; when adding yellow background; black is bold to add a comment.
| TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE = yes IPADDR=192.168.10.111 NETMASK=255.255.255.0 GATEWAY=192.168.10.1 DNS1 = 114114114114 IPV4_FAILURE_FATAL=no #IPV6INIT=yes #IPV6_AUTOCONF=yes # IPV6_DEFROUTE = yes #IPV6_FAILURE_FATAL=no #IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens33 UUID=7afc67d5-b767-4d89-97b4-2558f8dc33c3 DEVICE=ens33 ONBOOT=yes |
[Root @ localhost network-scripts] # nmcli c reload # restart card
