Linux网络配置的基本方法

LinuxProbe

进入Linux界面后，右击选择open terminal：

用ifconfig命令查看网络配置：

[root@localhost ~]# ifconfigens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500        ether 00:0c:29:b6:bb:ac txqueuelen 1000 (Ethernet)        RX packets 125 bytes 7500 (7.3 KiB)        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 0lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536        inet 127.0.0.1 netmask 255.0.0.0        inet6 ::1 prefixlen 128 scopeid 0x10        loop txqueuelen 1 (Local Loopback)        RX packets 76 bytes 6908 (6.7 KiB)        RX errors 0 dropped 0 overruns 0 frame 0        TX packets 76 bytes 6908 (6.7 KiB)        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500        inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255        ether 52:54:00:36:da:62 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是本地网络，不用管，virbr0是虚拟网卡，可以删除，主要配置ens33，删除virbr0：

[root@localhost ~]# ifconfig virbr0 down #关闭virbr0网卡[root@localhost ~]# brctl delbr virbr0 #删除virbr0网卡[root@localhost ~]# systemctl disable libvirtd.service  #因为虚拟网卡是libvirtd服务创建的，而该服务在Linux中没有太大用处，因此此处直接禁止开机启动Removed symlink /etc/systemd/system/multi-user.target.wants/libvirtd.service.Removed symlink /etc/systemd/system/sockets.target.wants/virtlockd.socket.Removed symlink /etc/systemd/system/sockets.target.wants/virtlogd.socket.

配置ens33：

[root@localhost ~]# cd /etc/sysconfig/network-scripts/ #网络配置文件路径[root@localhost network-scripts]# lsifcfg-ens33 ifdown-isdn ifup ifup-plip ifup-tunnelifcfg-lo ifdown-post ifup-aliases ifup-plusb ifup-wirelessifdown ifdown-ppp ifup-bnep ifup-post init.ipv6-globalifdown-bnep ifdown-routes ifup-eth ifup-ppp network-functionsifdown-eth ifdown-sit ifup-ib ifup-routes network-functions-ipv6ifdown-ib ifdown-Team ifup-ippp ifup-sitifdown-ippp ifdown-TeamPort ifup-ipv6 ifup-Teamifdown-ipv6 ifdown-tunnel ifup-isdn ifup-TeamPort更改ifcfg-ens33（可能名字会有所不同，但基本是这个）:[root@localhost network-scripts]# vim ifcfg-ens33 TYPE=Ethernet #网络类型BOOTPROTO=none #IP获取方式，有dhcp自动获取和静态IP（none/static）NAME=ens33 #网络名称UUID=d1755a41-8026-42f1-871d-9cd78fa2aa3c DEVICE=ens33 #驱动名称ONBOOT=yes #设置开机启动IPADDR=192.168.137.3 #设置静态IP地址NETMASK=255.255.255.0 #子网掩码GATEWAY=192.168.137.254 #网关DNS1=114.114.114.114 #DNSDNS2=202.96.134.133

保存退出后重启网络服务：

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

再查看下：

[root@localhost network-scripts]# ifconfigens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500        inet 192.168.137.2 netmask 255.255.255.0 broadcast 192.168.137.255        inet6 fe80::20c:29ff:feb6:bbac prefixlen 64 scopeid 0x20        ether 00:0c:29:b6:bb:ac txqueuelen 1000 (Ethernet)        RX packets 898 bytes 60524 (59.1 KiB)        RX errors 0 dropped 0 overruns 0 frame 0        TX packets 26 bytes 3920 (3.8 KiB)        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536        inet 127.0.0.1 netmask 255.0.0.0        inet6 ::1 prefixlen 128 scopeid 0x10        loop txqueuelen 1 (Local Loopback)        RX packets 100 bytes 9716 (9.4 KiB)        RX errors 0 dropped 0 overruns 0 frame 0        TX packets 100 bytes 9716 (9.4 KiB)        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

可以看到IP已经变了，为保险起见，可以ping一下：

[root@localhost network-scripts]# ping 192.168.137.2PING 192.168.137.2 (192.168.137.2) 56(84) bytes of data.64 bytes from 192.168.137.2: icmp_seq=1 ttl=64 time=0.142 ms64 bytes from 192.168.137.2: icmp_seq=2 ttl=64 time=0.045 ms64 bytes from 192.168.137.2: icmp_seq=3 ttl=64 time=0.030 ms64 bytes from 192.168.137.2: icmp_seq=4 ttl=64 time=0.063 ms64 bytes from 192.168.137.2: icmp_seq=5 ttl=64 time=0.033 ms

至此，网络配置完成。
