## Introduction This tutorial will walk you through creating a script to restart AzerothCore after a shutdown, restart, or crash when using a Linux server.

The easiest way to setup a restarter is by using our [integrated scripts or docker](how-to-restart-and-debug.md)

However, the following guy will show you how to create your own restarter from scratch.

## Creating The Scripts #### Prerequisites - Verify that your Linux server has screen and nano installed.

```sh sudo apt-get update && sudo apt-get install screen nano ```

- Once you've installed screen and nano, continue on to the next step.

#### Script Creation - Navigate to your server bin directory `~/azeroth-server/bin` and type `nano auth.sh` - In the new nano screen, enter the following script:

```sh #!/bin/sh while :; do ./authserver sleep 20 done ```

- Once entered, press Ctrl + O, hit Enter, and then Ctrl + X. That will save the new script and return you to the terminal. We've just created the Authserver restart script. Let's next create the Worldserver script. - Type `nano world.sh` - In the new nano screen, enter the following script:

```sh while :; do ./worldserver sleep 20 done ```

- Once entered, press Ctrl + O, hit Enter, and then Ctrl + X. That will save the new script and return you to the terminal. We've just created the Worldserver restart script. Let's next create a script that will launch both the Authserver and Worldserver restarter scripts. - Type `nano restarter.sh`

```sh #!/bin/bash screen -AmdS auth ./auth.sh screen -AmdS world ./world.sh ```

- Once entered, press Ctrl + O, hit Enter, and then Ctrl + X. Finally, let's create our server shutdown script. - Type `nano shutdown.sh`

```sh #!/bin/bash screen -X -S “world” quit screen -X -S “auth” quit ```

- Once entered, press Ctrl + O, hit Enter, and then Ctrl + X. Next, let's start our server.

## Server Management #### Server Startup - To start your server with the scripts, ensure you are in you server bin directory `~/azeroth-server/bin`. - We will start the restart scripts by typing the following command `./restarter.sh` - Side note: If you wish to start the server and see the worldserver console, use the following command `./restarter.sh; screen -r world`

#### Server Monitoring - To access and view the Authserver or Worldserver consoles: – Authserver: `screen -r auth` – Worldserver: `screen -r world` - When you want to exit the screen and return to your terminal, type Ctrl + A, followed by D.

#### Server Shutdown - To terminate the restarter and shutdown your server, ensure you are in you server bin directory `~/azeroth-server/bin`. - Type `./shutdown.sh` and the scripts will turn off and your server will terminate.
