4 guides
Create a sudo user on Ubuntu, Debian, AlmaLinux and Rocky Linux
Add a personal admin account with sudo rights, give it your SSH key, and test it properly before you stop logging in as root.
Edit the sudoers file safely with visudo
Change who can use sudo without breaking it. Learn the sudoers syntax, use visudo and drop-in files in /etc/sudoers.d, and grant full or limited admin rights.
Fix "permission denied" on the Docker socket
Fix the "permission denied while trying to connect to the Docker daemon socket" error. Add your user to the docker group, apply it without rebooting, and understand the security trade-off versus sudo.
Give a user sudo access to specific commands only
Grant a Linux user root rights for a short list of commands, such as restarting one service, using Cmnd_Alias and full paths, and avoid the wildcard and shell-escape traps.
