Operating System Compatibility
It is recommended that you use Ubuntu 16.04, as there have been nearly no problems with it. Music features are currently not working on CentOS. Also, 32-bit systems are incompatible.
Compatible operating systems
Ubuntu: 16.04, 18.04, 20.04
Mint: 17, 18
Debian: 9, 10
CentOS: 7, 8
Getting Started
Use the following command to get and run the linuxAIO.sh installer
(PS: Do Not rename the linuxAIO.sh file)
cd ~ && wget -N https://github.com/Wizkiller96/WizBot-BashScript/raw/1.9/linuxAIO.sh && bash linuxAIO.sh
You should see the main menu with the following options:
1
1. Download WizBot
2
2. Run WizBot (Normally)
3
3. Run WizBot with Auto Restart (Run WizBot normally before using this.)
4
4. Auto-Install Prerequisites (For Ubuntu, Debian and CentOS)
5
5. Set up credentials.json (If you have downloaded WizBot already)
6
6. Set up pm2 for WizBot (see README)
7
7. Start WizBot in pm2 (complete option 6 first)
8
8. Exit
Copied!
Downloading and Installing the Prerequisites
If you are running WizBot for the first time on your system and never had any prerequisites installed, press 4 and enter key, then y once you see the following:
1
Welcome to WizBot Auto Prerequisites Installer.
2
Would you like to continue?
Copied!
That will install all prerequisites your system needs in order to run WizBot.
(Optional) If you prefer to install them manually, you can try finding them here.
Once it finishes, the installer should automatically take you back to the main menu.
Installing WizBot
Choose Option 1 to get the most updated build of WizBot. When installation is complete, you will see the options again.
If you haven't set up your Discord bot application and invited the bot to your server yet, do it now.
Only the ClientID, Bot Token and OwnerID are required. Everything else is optional.
The Google API Key is required if you want WizBot to play music.
Once you have acquired them, choose Option 5 to set up your credentials.
You will be asked to enter your credentials. Just follow the on-screen instructions and enter them as requested. (i.e. If you are asked to insert the Bot's Token, then just copy and paste the Bot's Token and hit Enter. Rinse and repeat until it's over.)
If you want to skip any optional information, just press Enter without typing/pasting anything.
Once you're done with the credentials, you should be taken back to the main menu.
Checking if WizBot is working
Choose Option 2 to Run WizBot (Normally).
Check in your Discord server if your new bot is working properly. Once you're done testing, type .die to shut it down and return to the main menu.
You can now choose Option 3 and have WizBot run with auto restart. It will work just fine, however it's strongly advised that you use WizBot with a process manager like pm2 or tmux, as they will keep WizBot running in the background, freeing up your terminal for other tasks.
Setting up, Running and Updating WizBot with pm2 [strongly recommended]
WizBot can be run using pm2, a process manager that seamlessly handles keeping your bot up. Besides, it handles disconnections and shutdowns gracefully, ensuring any leftover processes are properly killed. It also persists on server restart, so you can restart your server or computer and pm2 will manage the startup of your bot. Lastly, there is proper error logging and overall logging. These are just a few features of pm2, and it is a great way to run WizBot with stability.
Setting up pm2/NodeJS for WizBot
Before proceeding, make sure your bot is not running by either running .die in your Discord server or exiting the process with Ctrl+C.
You may be presented with the installer main menu once you shut your bot down. If not, simply run bash linuxAIO.sh.
Run Option 6 to install NodeJS and pm2.
If you already have NodeJS and pm2 installed on your system, you can skip this step (which is a one-time thing).
There is an automated script built in the installer so installation and startup is a breeze. Just select Option 7 to bring you to a menu of choices. These are the normal choices you have for running WizBot.
1
[1] Start with auto-restart with .die and no auto-update.
2
[2] Start with auto-restart with .die and auto-update on restart as well.
3
[3] Run normally without any auto-restart or auto-update functionality.
Copied!
Simply choose one of these and WizBot will start in pm2! If you did everything correctly, you can run the following to check your WizBot setup:
sudo pm2 status to see all pm2 processes
sudo pm2 info WizBot information about WizBot
sudo pm2 logs WizBot to view real-time logs of WizBot, or
sudo pm2 logs WizBot --lines number (number = how many lines you wish to output) to see a specific amount of lines of the log. The logfile is also stored and presented at the top of these commands
Updating WizBot with pm2
If you have set up WizBot with auto-update, simply run .die on your Discord server. That's it!
If you have set up WizBot with no auto-update:
Shut your bot down with sudo pm2 stop WizBot
Open the installer with bash linuxAIO.sh and choose Option 1
Once it's done, exit the installer with Option 8 and run sudo pm2 restart WizBot
You can watch your bot going online with sudo pm2 logs WizBot
Running WizBot on tmux [if you don't want to use pm2]
Before proceeding, make sure your bot is not running by either running .die in your Discord server or exiting the process with Ctrl+C. If you are presented with the installer main menu, exit it by choosing Option 8.
Create a new session: tmux new -s WizBot  
The above command will create a new session named WizBot (you can replace “WizBot” with anything you prefer, it's your session name).
Run the installer: bash linuxAIO.sh
Choose 2 to Run WizBot normally.
NOTE: With this option, if you use .die in Discord, the bot will shut down and stay offline until you manually run it again.
Choose 3 to Run WizBot with Auto Restart.
NOTE: With this option, the bot will auto run if you use .die, making it to function as restart.
You will be shown the following options:
1
1. Run Auto Restart normally without Updating.
2
2. Run Auto Restart and update WizBot.
3
3. Exit
Copied!
With option 1. Run Auto Restart normally without Updating, the bot will restart on .die command and will not download the latest build available.
With option 2. Run Auto Restart and update WizBot, the bot will restart and download the latest build available everytime the .die command is used.
Now check your Discord server, the bot should be online
To move the bot to the background, press Ctrl+B, release the keys then hit D. That will detach the session, allowing you to finally close the terminal window and not worry about having your bot shut down in the process.
Updating WizBot
If you're running WizBot with auto-update, just type .die in your Discord server. That's it!
If you're running WizBot with no auto-update:
Kill your previous session.
Check the session name with tmux ls
Kill with tmux kill-session -t WizBot (don't forget to replace "WizBot" with whatever you named your bot's session).
Create a new session: tmux new -s WizBot
Run this command: cd ~ && wget -N https://github.com/Wizkiller96/WizBot-BashScript/raw/1.9/linuxAIO.sh && bash linuxAIO.sh
Choose Option 1 to download the most up to date version of WizBot.
Once it's done, choose Option 2 or 3 and detach the session by pressing Ctrl+B, release then D.
Additional Information
If you want to see the active sessions, run tmux ls. That will give you the list of the currently running sessions.
If you want to switch to/see a specific session, type tmux a -t WizBot (WizBot is the name of the session we created before so, replace “WizBot” with the session name you have created).
If you want to go through the log, press Ctrl+B, release the keys then hit Page Up or Page Down to navigate.
Don't forget to always detach from the session by pressing Ctrl+B then D once you're done.
If you want create a new session, run tmux new -s WizBot. If you want to kill it, run tmux kill-session -t WizBot
Making WizBot persist upon system restarts (tmux - For Advanced Users)
This procedure is completely optional. We'll be using systemd to handle WizBot during system shutdowns and reboots.
1. Start off by downloading the necessary scripts:
cd ~ && wget https://raw.githubusercontent.com/Wizkiller96/WizBot-BashScript/1.9/wizbot.service
cd ~ && wget https://raw.githubusercontent.com/Wizkiller96/WizBot-BashScript/1.9/WizBotARN.sh
cd ~ && wget https://raw.githubusercontent.com/Wizkiller96/WizBot-BashScript/1.9/WizBotARU_Latest.sh
2. If you are logged in as root and don't want WizBot to auto-update, ignore the procedures below and go straight to step 3.
Let's edit the script systemd is going to use to start WizBot: nano wizbot.service
You should see the following:
1
[Unit]
2
Description=WizBot
3
​
4
[Service]
5
WorkingDirectory=/root
6
User=root
7
Type=forking
8
ExecStart=/usr/bin/tmux new-session -s WizBot -d '/bin/sh WizBotARN.sh'
9
ExecStop=/bin/sleep 2
10
​
11
[Install]
12
WantedBy=multi-user.target
Copied!
Change /root from "WorkingDirectory" to the directory that contains your WizBot folder.
For example, if your  bot is located in /home/username/WizBot, you should change /root to /home/username.
Change root from "User" to whatever username you're using.
Optional: If you want WizBot to auto-update upon restarts, change WizBotARN.sh to WizBotARU_Latest.sh.
Once you're done, press Ctrl+X to exit nano, type y to confirm the changes and Enter to go back to the terminal.
3. Now the script needs to be moved to where systemd stores their services. On Ubuntu, it's usually in /etc/systemd/system. If you are not using Ubuntu and are unsure about where systemd stores stuff, Google is your best friend.
To do that, run this command: sudo mv wizbot.service /etc/systemd/system/wizbot.service
4. Now it's time to reload systemd, so it loads our new script up: sudo systemctl daemon-reload
5. Set the script to run upon system restarts: sudo systemctl enable WizBot
6. Start WizBot on the current session: sudo systemctl start WizBot
And that's it. Every time your system restarts, systemd should automatically startup your bot with tmux. If everything has gone well, you should be able to see WizBot on the list of processes being handled by tmux by running the tmux ls command.
Managing WizBot on tmux with systemd
Here is a list of useful commands if you intend on managing WizBot with systemd.
tmux ls - lists all processes managed by tmux.
tmux a -t WizBot - shows WizBot's log (press Ctrl+B then D to exit).
sudo systemctl start WizBot - starts WizBot, if it has been stoped.
sudo systemctl restart WizBot - restarts WizBot. Can be used while the bot is being run.
sudo systemctl stop WizBot - completely shuts WizBot down.
sudo systemctl enable WizBot - makes WizBot start automatically upon system reboots.
sudo systemctl disable WizBot - stops WizBot from starting automatically upon system reboots.
sudo systemctl status WizBot - shows some information about your bot (press Ctrl+C to exit).
Setting up WizBot on a Linux VPS (Digital Ocean Droplet)
If you want WizBot to play music for you 24/7 without having to hosting it on your PC and want to keep it cheap, reliable and convenient as possible, you can try WizBot on Linux Digital Ocean Droplet using the link DigitalOcean (by using this link, you will get $10 credit and also support WizBot)
Setting up WizBot Assuming you have followed the link above to setup an account and a Droplet with a 64-bit operational system on Digital Ocean and got the IP address and root password (in your e-mail) to login, it's time to get started.
This section is only relevant to those who want to host WizBot on DigitalOcean. Go through this whole section before setting the bot up.
Prerequisites
Download PuTTY​
Download WinSCP (optional)
​Create and invite the bot.
Starting up
Open PuTTY and paste or enter your IP address and then click Open.
If you entered your Droplets IP address correctly, it should show login as: in a newly opened window.
Now for login as:, type root and press enter.
It should then ask for a password. Type the root password you have received in your e-mail address, then press Enter.
If you are running your droplet for the first time, it will most likely ask you to change your root password. To do that, copy the password you've received by e-mail and paste it on PuTTY.
To paste, just right-click the window (it won't show any changes on the screen), then press Enter.
Type a new password somewhere, copy and paste it on PuTTY. Press Enter then paste it again. Save the new password somewhere safe.
After that, your droplet should be ready for use. Follow the guide from the beginning to set WizBot up on your newly created VPS.
