Linux CentOS CentOS 7 設置網絡IP地址1，CentOS 7自動獲得一個IP地址
1，網卡的信息在/etc/sysconfig/network-scripts裏面，你可以編輯下面的ifcfg-ens33的文件，來手動綁定IP地址
(182.254.152.182) 56(84) bytes of data.

自動獲得IP地址
1，CentOS 7自動獲得一個IP地址
[root@aminglinux ~]# dhclient
2，查看網卡信息，會發現有一個ens33的網卡
[root@aminglinux ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:15:d9:1a brd ff:ff:ff:ff:ff:ff
inet 192.168.188.129/24 brd 192.168.188.255 scope global ens33
valid_lft forever preferred_lft forever
valid_lft forever preferred_lft forever
手動設置網卡的IP地址
1，網卡的信息在/etc/sysconfig/network-scripts裏面，你可以編輯下面的ifcfg-ens33的文件，來手動綁定IP地址
（紅色的部分是需要修改和添加的內容），修改完成後。按下ESC鍵，再輸入“：wq"並回車保存退出。
[root@aminglinux ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=a69273cd-4aab-4cb7-8a24-8a100dd6c011
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.188.129
NETMASK=255.255.255.0
GATEWAY=192.168.188.2
DNS1=119.29.29.29
2，重啟系統的網絡服務，再查看下IP地址
[root@aminglinux ~]# systemctl restart network.service
[root@aminglinux ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:15:d9:1a brd ff:ff:ff:ff:ff:ff
inet 192.168.188.129/24 brd 192.168.188.255 scope global ens33
valid_lft forever preferred_lft forever
inet6 fe80::e3ea:d232:efe0:c71/64 scope link
valid_lft forever preferred_lft forever
3，最後測試下網絡的連通性。
[root@aminglinux ~]# ping -c 4
