Iv. Q & A and Summary 1. Partition Rules

If you want to work in an enterprise, when you need to install the CentOS operating system, the partition should follow the requirements of the company's leaders. If the leaders do not have requirements, follow the rules described in this article. The details are as follows:

2. Set the ROOT password.

The ROOT user password should be as complex as possible, preferably a combination of uppercase and lowercase letters and numbers. Otherwise, the password may be easily cracked.
