Linux的網(wǎng)絡(luò)配置
作為一個(gè)linux的瘋狂熱愛(ài)者，我們首先需要掌握的就是在linux系統(tǒng)下怎么配置IP、路由和主機(jī)名基本的linux網(wǎng)絡(luò)配置，本篇文章重點(diǎn)為大家講解一下Linux的網(wǎng)絡(luò)配置。
進(jìn)入Linux界面后，右擊選擇open terminal：
會(huì)出現(xiàn)命令行窗口：
用ifconfig命令查看網(wǎng)絡(luò)配置：
[root@localhost ~]# ifconfig
ens33: flags=4163
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 0 lo: flags=73
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 0 virbr0: flags=4099
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是本地網(wǎng)絡(luò)，不用管，virbr0是虛擬網(wǎng)卡，可以刪除，主要配置ens33，刪除virbr0：
[root@localhost ~]# ifconfig virbr0 down #關(guān)閉virbr0網(wǎng)卡
[root@localhost ~]# brctl delbr virbr0 #刪除virbr0網(wǎng)卡
[root@localhost ~]# systemctl disable libvirtd.service #因?yàn)樘摂M網(wǎng)卡是libvirtd服務(wù)創(chuàng)建的，而該服務(wù)在Linux中沒(méi)有太大用處，因此此處直接禁止開(kāi)機(jī)啟動(dòng)
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/ #網(wǎng)絡(luò)配置文件路徑
[root@localhost network-scripts]# ls
ifcfg-ens33 ifdown-isdn ifup ifup-plip ifup-tunnel
ifcfg-lo ifdown-post ifup-aliases ifup-plusb ifup-wireless
ifdown ifdown-ppp ifup-bnep ifup-post init.ipv6-global
ifdown-bnep ifdown-routes ifup-eth ifup-ppp network-functions
ifdown-eth ifdown-sit ifup-ib ifup-routes network-functions-ipv6
ifdown-ib ifdown-Team ifup-ippp ifup-sit
ifdown-ippp ifdown-TeamPort ifup-ipv6 ifup-Team
ifdown-ipv6 ifdown-tunnel ifup-isdn ifup-TeamPort
更改ifcfg-ens33（可能名字會(huì)有所不同，但基本是這個(gè)）:
[root@localhost network-scripts]# vim ifcfg-ens33
TYPE=Ethernet #網(wǎng)絡(luò)類(lèi)型
BOOTPROTO=none #IP獲取方式，有dhcp自動(dòng)獲取和靜態(tài)IP（none/static）
NAME=ens33 #網(wǎng)絡(luò)名稱(chēng)
UUID=d1755a41-8026-42f1-871d-9cd78fa2aa3c
DEVICE=ens33 #驅(qū)動(dòng)名稱(chēng)
ONBOOT=yes #設(shè)置開(kāi)機(jī)啟動(dòng)
IPADDR=192.168.137.3 #設(shè)置靜態(tài)IP地址
NETMASK=255.255.255.0 #子網(wǎng)掩碼
GATEWAY=192.168.137.254 #網(wǎng)關(guān)
DNS1=114.114.114.114 #DNS
DNS2=202.96.134.133
保存退出后重啟網(wǎng)絡(luò)服務(wù)：
[root@localhost network-scripts]# systemctl restart network.service
再查看下：
[root@localhost network-scripts]# ifconfig
ens33: flags=4163
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 0 lo: flags=73
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已經(jīng)變了，為保險(xiǎn)起見(jiàn)，可以ping一下：
[root@localhost network-scripts]# ping 192.168.137.2
PING 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 ms
64 bytes from 192.168.137.2: icmp_seq=2 ttl=64 time=0.045 ms
64 bytes from 192.168.137.2: icmp_seq=3 ttl=64 time=0.030 ms
64 bytes from 192.168.137.2: icmp_seq=4 ttl=64 time=0.063 ms
64 bytes from 192.168.137.2: icmp_seq=5 ttl=64 time=0.033 ms
至此，網(wǎng)絡(luò)配置完成。
