    作业一:临时配置网络(ip,网关,dns)+永久配置

    1. 配置网络信息

    [root@localhost ~]# ifconfig

    eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

            inet 192.168.202.131  netmask 255.255.255.0  broadcast 192.168.202.255

            inet6 fe80::20c:29ff:fe9d:a0df  prefixlen 64  scopeid 0x20<link>

            ether 00:0c:29:9d:a0:df  txqueuelen 1000  (Ethernet)

            RX packets 23620  bytes 2085149 (1.9 MiB)

            RX errors 0  dropped 0  overruns 0  frame 0

            TX packets 12933  bytes 1815875 (1.7 MiB)

            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 2767  bytes 389871 (380.7 KiB)

            RX errors 0  dropped 0  overruns 0  frame 0

            TX packets 2767  bytes 389871 (380.7 KiB)

            TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

    [root@localhost ~]# ifconfig eno16777736 192.168.202.132/24

    Connection closed by foreign host.

    [root@localhost network-scripts]# ifconfig

    eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

            inet 192.168.202.132  netmask 255.255.255.0  broadcast 192.168.202.255

            inet6 fe80::20c:29ff:fe9d:a0df  prefixlen 64  scopeid 0x20<link>

            ether 00:0c:29:9d:a0:df  txqueuelen 1000  (Ethernet)

            RX packets 23954  bytes 2108353 (2.0 MiB)

            RX errors 0  dropped 0  overruns 0  frame 0

            TX packets 13040  bytes 1827860 (1.7 MiB)

            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 2767  bytes 389871 (380.7 KiB)

            RX errors 0  dropped 0  overruns 0  frame 0

            TX packets 2767  bytes 389871 (380.7 KiB)

            TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

    1. 配置网关

    [root@localhost network-scripts]# vim /etc/resolv.conf

    [root@localhost network-scripts]# route add default gw 192.168.202.2 netmask 255.255.255.0

    [root@localhost /]# route -n

     [root@localhost /]# route del default gw 192.168.202.2 netmask 255.255.255.0

    [root@localhost /]# route -n

    3.永久配置

    [root@localhost /]# cd /etc/sysconfig/network-scripts/

    [root@localhost network-scripts]# ls

     [root@localhost network-scripts]# vim ifcfg-eno16777736
