redhat7使用nmtui配置网络

1、查看当前网卡

[root@localhost Desktop]# ifconfig
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 00:0c:29:af:60:a0  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 386  bytes 32780 (32.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 386  bytes 32780 (32.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

2、命令行输入nmtui，出现如下界面，直接回车

3、出现如下界面，选编辑，回车

4、将Automatically改为manual

5、选中show，然后后车

6、出现如下界面

7、设定ip

8、选ok，然后回车

9、选quit

10、再次查看网络

[root@localhost Desktop]# ifconfig
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 00:0c:29:af:60:a0  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 642  bytes 54540 (53.2 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 642  bytes 54540 (53.2 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

11、进入网卡配置文件目录

[root@localhost Desktop]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# ls
ifcfg-eno16777728  ifdown-ppp       ifup-eth     ifup-sit
ifcfg-lo           ifdown-routes    ifup-ippp    ifup-Team
ifdown             ifdown-sit       ifup-ipv6    ifup-TeamPort
ifdown-bnep        ifdown-Team      ifup-isdn    ifup-tunnel
ifdown-eth         ifdown-TeamPort  ifup-plip    ifup-wireless
ifdown-ippp        ifdown-tunnel    ifup-plusb   init.ipv6-global
ifdown-ipv6        ifup             ifup-post    network-functions
ifdown-isdn        ifup-aliases     ifup-ppp     network-functions-ipv6
ifdown-post        ifup-bnep        ifup-routes
[root@localhost network-scripts]# pwd
/etc/sysconfig/network-scripts

12、使用vim编辑网卡配置文件，将ONBOOT选项改为yes，意思是自动启动网卡

[root@localhost network-scripts]# vim ifcfg-eno16777728
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=eno16777728
UUID=2acdeb41-84b7-48c4-b552-a4ecca60729f
ONBOOT=yes
HWADDR=00:0C:29:AF:60:A0
IPADDR0=192.168.10.10
PREFIX0=20
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

13、重新启动网卡

[root@localhost network-scripts]# systemctl restart network

14、再次查看网络，配置已生效

[root@localhost network-scripts]# ifconfig
eno16777728: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.10.10  netmask 255.255.240.0  broadcast 192.168.15.255
        inet6 fe80::20c:29ff:feaf:60a0  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:af:60:a0  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 30  bytes 4121 (4.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 642  bytes 54540 (53.2 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 642  bytes 54540 (53.2 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
