First, the clone cannot be started:

Device eth0 does not seem to be present, delaying initialization

Fault background:

A virtual machine with an existing CentOS was completely cloned in vmware workstation, and after startup, it was found that the network card did not start. So restart the network service and find the error message "Device eth0 does not seem to be present, delaying initialization."

The cause of the failure:

Due to the cloning of the virtual machine, vmware only modifies the name of the virtual machine, but does not modify any information in the virtual hard disk, resulting in a discrepancy between the MAC address of the cloned network card and the mac address recorded in the operating system, resulting in the failure of eth0 startup. The operating system records the addition of a new network card. The name eth2,mac address of the new network card is the new mac address assigned by vmware.

Solution:

Modify / etc/udev/rules.d/70-persistent-net.rules file

Delete the information about eth0. Modify the name of the second eth2 network card to eth0.

The mac address in modified / etc/sysconfig/network-scripts/ifcfg-eth0 is the mac address of the modified eth0 in / etc/udev/rules.d/70-persistent-net.rules.

Restart the server.

There are several operating system environment variables set for language items, and I often set these two LANG and NLS_LANG. LANG is for the Linux system language, region, character set settings, valid for applications under linux, such as date;NLS_LANG is for Oracle language, region, character set settings, effective for oracle tools.
