2. Modify the configuration

2.1 Modify the host name

1. Temporarily modify the host name

sudo hostnamectl set-hostname 主机名

2. Modify the configuration file:

• /etc/hosts

sudo vi /etc/hosts

• /etc/sysconfig/network

sudo vi /etc/sysconfig/network

3. The reboot command restarts the server
4. Check the host name:

hostnamectl 或 hostname

2.2 Modify ip

vi /etc/sysconfig/network-scripts/ifcfg-eth32

Note: ifcfg-eth0 is the name of the network card, pay attention to what your network card name is.

2.3 Modify UUID

The UUID after cloning a virtual machine is generally the same and needs to be modified.

1. Generate new uuid

uuidgen

2. Write the generated uuid to the network card configuration file

vi /etc/sysconfig/network-scripts/ifcfg-eth32

2.4 Delete the /etc/udev/rules.d/70-persistent-net.rules file

mv –f /etc/udev/rules.d/70-persistent-net.rules rules.back

2.5 Modify the MAC address

Modify the configuration file and delete the HWADDR content.

cat /sys/class/net/eth0/address #查看eth0的MAC地址

2.6 Configure DNS Resolution

sudo vi /etc/resolv.conf

Add to:

nameserver  8.8.8.8  

Restart the gateway:

sudo service network restart
