What should I do if centos cannot obtain an IP? Solution to the problem of not being able to obtain the IP after installing centos

Many times, after installing in the virtual machine, go into centos and use ifconfig to find that there is no such command. You can use ip a to check the IP,

If there is no ip, centos is generally installed without enabling the network card by default. Solution:

CentOS configures the network card to automatically obtain the IP address upon startup

Open /etc/sysconfig/network-scripts /ifcfg-eth0 Change ONBOOT="no" to ONBOOT="yes"

After saving: systemctl restart network

can solve this problem.
