cd /etc/sysconfig/network-scripts/

(Recommended tutorial: centos tutorial)

2. ls finds ifcfg-**** (the asterisk part is random) and open it with vi

3. Change ONBOOT=no to yes

4. :wq Save and exit

5. Restart the network service

service network restart

3. If possible The network is connected, but the installation of yum install links (example) fails. The reason is that the speed is too slow, just change the mirror source. As follows:

1. Back up your original image file so that you can restore it after making an error.

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

If you can’t find the original one, just use the new source directly.

2. Download the new CentOS-Base.repo to /etc/yum.repos.d/

CentOS 7:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

or

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3. Run yum makecache to generate cache
