Linux adds sudo permissions to users

Linux, the general user will run the sudo command when the error message appears:such as Vurtne is isn't in the sudoers file. This incident would be reported.
here, Vurtne is the generic user name and then causes the sudo command to be unable to execute, at which point the following resolves:1. Enter the Super User mode, which is to log into the system with root. 2. Add Write permission to the/etc/sudoers file:chmod u+w/etc/sudoers
3. Edit the/etc/sudoers file. vim/etc/sudoersin root all= (All) alladd vurtne all= (All)all (here Vurtne for your username) and save the exit. 4. Revoke write access to the/etc/sudoers file:chmod u-w/etc/sudoers the sudo command can then be used normally by the general user.
