Creating a User Group and a User

In a server environment, independent users are assigned to each process to implement permission isolation for security purposes. The user groups and users are created for the OS, not for the database.

1. Create a user group and a user. Both the user group name and user name are mysql.

   1 2	groupadd mysql useradd -g mysql mysql

   

   To delete the user group and user, run the following command:

   1 2	id mysql userdel -r mysql

2. Set the password of user mysql. Enter the same password twice as prompted.

   1	passwd mysql
