In this case, sudo can be used instead. By default, the new user is not in The sudo group. You need to edit the/etc/sudoers file to add the user. The file can only use the mongodo command, First, you need to switch to root and su-(note that there are-, which is different from su. When you use the "su" command, you only need to switch to root, however, if the root environment variable is not passed, it is still the currently used environment variable. The "su-" command is used to bring the environment variable together, just like the root login ). Then mongodo or vim/etc/sudoers, and mongodo are used in the same way as vi. Move the cursor to the next line of root ALL = (ALL) ALL and enter your_user_name ALL = (ALL) ALL; Save and exit; In this way, you can add yourself to the sudo group and use the sudo command.
