1. Check the network profile
Probably because of the different systems, the configuration file is different, in general, the configuration files are prefix: ifcfg-eno + suffix: of random numbers
Into the / etc / sysconfig / network-scripts directory, and by the ls command to view the network profile, generally the first one is.
$ cd /etc/sysconfig/network-scripts
$ ls
2. Edit the ifcfg-eno profile
Amended as follows red marker place
$ vi ifcfg-eno16777736
Configuration instructions:
BOOTPROTO: Be sure to set as static, or after you configure through ifconfig to view, two IP addresses will appear;
GATEWAY: If CentOS is running on VMware, the gateway can "edit - Virtual Network Editor --NAT Settings" to see to;
HWADDR: MAC address can be viewed through the command ip addr
[root@localhost ~]# ip addr
1: lo:
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: eno16777736:
link/ether00:0f:19:10:12:f1 brd ff:ff:ff:ff:ff:ff
inet 192.168.38.135/24 brd 192.168.38.255 scope global dynamic eno16777736
valid_lft 1681sec preferred_lft 1681sec
inet6 fe80::20c:11aa:ae11:4fe4/64 scope link
valid_lft forever preferred_lft forever
Red font 0f: 19: 10: 12: f1 is the MAC address
3. Restart card
$ service network restart
If the configuration is successful in ..ok said that if ..failed appear, it is likely that HWADDR configuration problem.
