Tmux is by far one of the most useful tools in the linux arsenal especially for long running jobs. Tmux is a linux terminal multiplexer, it allows terminal sessions to remain active long after the user has logged off their workstation.
In this tutorial I'll be using a CentOS 8 virtual machine.
First you will need to install the package for tmux.
yum install tmux -y
Create a new session:
Create a new tmux session. I will name my session NEW_SESSSION.
tmux new -s NEW_SESSION
Attach to new session:
The next step is to attach to the newly created session.
tmux attach -t NEW_SESSION
Detach from tmux session:
On your keyboard, press the following keys at the same time:
This will keep the session running in the background, but will not terminate it.
Check running session:
To check what running sessions are available to connect to. You can use the following command to list all of the active sessions.
Terminating a session:
When you no longer need the tmux session you can terminate it by using the
tmux kill-session -t NEW_SESSION
Tmux has been super valuable in my professional life! Instead of designing a script to run in the background or using nohup, tmux allows to run the process in foreground in a persistent terminal session. Ideal for running a Minecraft server because it has a tendency to cause issues if ran in the background.
