First, add a normal user with the adduser command, as follows:

# adduser tommy// add a user named tommy # passwd tommy// change password Changing password for user tommy.New UNIX password: / / enter the new password here Retype new UNIX password: / / enter the new password passwd: all authentication tokens updated successfully.

2. Give root permission

Method 1: modify the / etc/sudoers file, find the following line, and remove the previous comment (#)

# # Allows people in group wheel to run all commands%wheel ALL= (ALL) ALL

Then modify the user to belong to the root group (wheel), with the following command:

# usermod-g root tommy

After the modification, you can now log in with your tommy account, and then use the command su-to get root permission to operate.

Method 2: modify the / etc/sudoers file, find the following line, and add a line under root, as follows:

# # Allow root to run any commands anywhereroot ALL= (ALL) ALLtommy ALL= (ALL) ALL

After the modification, you can now log in with your tommy account, and then use the command su-to get root permission to operate.
