Essential for centos installation-Basic settings and missing files

It is mainly because centos is installed on virtual machines and some settings are always made every time.

Purely Basic settings. For example, the local securecrt can connect to centos in the virtual machine.

For complex non-basic settings, see Linux Command collection.

Getcwd: cannot access parent directories Solution

The getcwd command cannot locate the current working directory. Generally, this is because you RM this directory after you CD it to a directory.
Getcwd is reported when you execute some service scripts.
You only need to run the CD command in any directory that actually exists.
The reason for this is that the current user does not have the executable permission for the current directory.
