Setting up NadekoBot on Linux

Setting up NadekoBot on Linux Digital Ocean Droplet
If you want Nadeko 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 Nadeko on Linux Digital Ocean Droplet using the link DigitalOcean (and using this link will be supporting Nadeko and will give you $10 credit)

Operating System Compatibility It is recommended that you get Ubuntu 16.04, as there have been nearly no problems with it. Also, 32-bit systems are incompatible.

Compatible operating systems: - Ubuntu: 14.04, 16.04, 16.10, 17.04, 17.10 - Debian 8 - CentOS 7

Setting up NadekoBot
Assuming you have followed the link above to setup an account and Droplet with 64bit OS in Digital Ocean and got the IP address and root password (in email) to login, its time to get started.

Go through this whole guide before setting up Nadeko

Prerequisites

Starting up

  • Open PuTTY.exe that you downloaded before, 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 password, type the root password you have received in your email address registered with Digital Ocean, then press Enter.

If you are running your VPS/ droplet for the first time, it will most likely ask you to change your VPS root password, to do that, type the password you received through email it won't show any changes on the screen like ****** when password is being typed, press Enter once done.
Type a new password, press Enter and type the new password again and you're done.
Write down and save the new password somewhere safe.
After you've done that, you are ready to use your VPS.

Getting NadekoBot

Part I - Downloading the installer

Use the following command to get and run linuxAIO.sh
(Remember Do Not rename the file linuxAIO.sh)

cd ~ && wget -N https://github.com/Kwoth/NadekoBot-BashScript/raw/1.9/linuxAIO.sh && bash linuxAIO.sh

You should see these following options after using the above command:

1. Download NadekoBot
2. Run Nadeko (Normally)
3. Run Nadeko with Auto Restart (Run Nadeko normally before using this.)
4. Auto-Install Prerequisites (For Ubuntu, Debian and CentOS)
5. Set up credentials.json (If you have downloaded NadekoBot already)
6. Set up pm2 for NadekoBot (see README)
7. Start Nadeko in pm2 (complete option 6 first)
8. Exit
Part II - Downloading Nadekobot prerequisites

If you are running NadekoBot for the first time on your system and never had any prerequisites installed and have Ubuntu, Debian or CentOS, Press 4 and enter key, then y when you see the following:

Welcome to NadekoBot Auto Prerequisites Installer.
Would you like to continue?

That will install all the prerequisites your system need to run NadekoBot.
(Optional) If you want to install it manually, you can try finding it here.

Once prerequisites finish installing,

Part III - Installing Nadeko

Choose 1 to get the most updated build of NadekoBot

and then press enter key.

When installation is complete, you will see the options again.

Next, check out:

Part IV - Setting up credentials

You will need the following for the next step: botimg

Once you have acquired them, press 5 to Set up credentials.json

You will be asked to enter the required informations, just follow the on-screen instructions and enter the required information.
i.e If you are asked Bot's Token, then just copy and paste or type the Bot's Token and press enter key.

(If you want to skip any optional infos, just press enter key without typing/pasting anything.)
Once done,

Part V - Checking if Nadeko is working

You should see the options again.
Next, press 2 to Run Nadeko (Normally). Check in your discord server if your new bot is working properly.

If you followed Part V and started Nadeko, make sure to exit the bot by using .die if it is running in your server, and/or by pressing 8 in the console to exit.

You may be presented with the installer main menu from Step I. If not, simply download it again as described in the following section.

Nadeko can be run using pm2, a process manager that seamlessly handles keeping your bot up. Besides this, 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 VPS/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 Nadeko with stability.

Setting up pm2/NodeJS for Nadeko

If you already have NodeJS and pm2 installed on your system, you can skip the Option 6 for installing pm2 which is a one-time thing. Scroll down to see startup instructions.

There is an automated script built in the Nadeko installer so installation and startup is a breeze. You may already have the linuxAIO.sh file downloaded from the first step, but you should download it again to keep up to date for potential changes in the installer. Download linuxAIO.sh:

cd ~ && wget -N https://github.com/Kwoth/NadekoBot-BashScript/raw/1.9/linuxAIO.sh

We can then run the script: sudo bash linuxAIO.sh and you will be presented with the normal Nadeko installer options.

Make sure you have installed Nadeko with the first option [1] before doing this, and also have installed the prerequisites with step [4].

Simply choose Option 6 to setup pm2 and install it along with NodeJS. This will update your NodeJS so there's no harm running it even if you have NodeJS on your system. It will also install pm2 and then exit to the installer menu again.

Running Nadeko with pm2 and Updating Nadeko within pm2

Once you are done installing pm2 with NodeJS, then you can select Option 7 which will bring you to a menu of choices. These are the normal choices you have for running Nadeko.

  • [1] Start with auto-restart with .die and no auto-update.
  • [2] Start with auto-restart with .die and auto-update on restart as well.
  • [3] Run normally without any auto-restart or auto-update functionality.

+Simply choose one of these and Nadeko will start in pm2! If you did everything correctly, you can run the following to check your Nadeko setup:

sudo pm2 status to see all pm2 processes

sudo pm2 info Nadeko information about Nadeko

sudo pm2 logs Nadeko to view real-time logs of Nadeko (you can do sudo pm2 logs Nadeko --lines <number>) (number = how many lines you wish to output) for viewing more lines of the log. The logfile is also stored and presented at the top of these commands.

Updating Nadeko within pm2:

If you don't auto-update Nadeko and manually do, one simply needs to run the linuxAIO.sh script: sudo sh linuxAIO.sh as we normally would and choose [1] Download NadekoBot, then after downloading is complete/build is done, just pm2 restart Nadeko -- that's all!

NOTE: If you did the pm2 setup, you are done! You do not need to follow the startup instructions later in the guide, as we've used the script and pm2 to start Nadeko up already. Wasn't that easy? :-)

Some other useful pm2 commands:

sudo pm2 startup && sudo pm2 save will setup pm2 to persist even on system reboot by saving the process ID information as a system service. Just need to do this once if you wish.

sudo pm2 stop Nadeko will stop Nadeko properly and ensure it is shut down. sudo pm2 restart Nadeko will restart Nadeko properly as well, shutting it down first and promptly restarting.

This is the recommended way to keep Nadeko running smoothly.

Part VII - Running Nadeko on tmux [if you wish not to use pm2]

If your bot is working properly in your server, type .die to shut down the bot, then press 8 on the console to exit. Next, Run your bot again with tmux.

Check this when you need to restart your NadekoBot anytime later along with tmux session.

Running NadekoBot

Create a new Session:

  • tmux new -s nadeko

The above command will create a new session named nadeko (you can replace “nadeko” with anything you prefer and remember its your session name) so you can run the bot in background without having to keep the PuTTY running.

Next, we need to run linuxAIO.sh in order to get the latest running scripts with patches:

  • cd ~ && wget -N https://github.com/Kwoth/NadekoBot-BashScript/raw/1.9/linuxAIO.sh && bash linuxAIO.sh

From the options,

Choose 2 to Run NadekoBot normally.
NOTE: With option 2 (Running normally), if you use .die command in discord. The bot will shut down and will stay offline until you manually run it again. (best if you want to check the bot.)

Choose 3 to Run NadekoBot with Auto Restart.
NOTE: With option 3 (Running with Auto Restart), bot will auto run if you use .die command making the command .die to function as restart.

It will show you the following options: 

1. Run Auto Restart normally without Updating.
2. Run Auto Restart and update NadekoBot.
3. Exit
  • With option 1. Run Auto Restart normally without Updating. Bot will restart on die command and will not be downloading the latest build available.
  • With option 2. Run Auto Restart and update NadekoBot. Bot will restart and download the latest build of bot available everytime die command is used.

Remember that, while running with Auto Restart, you will need to close the tmux session to stop the bot completely.

Now check your Discord, the bot should be online

Next to move the bot to background and to do that, press CTRL+B, release, D (that will detach the nadeko session using TMUX) and you can finally close PuTTY.

Restarting Nadeko

Restarting NadekoBot:

If you have chosen option 2 to Run Nadeko with Auto Restart from Nadeko's linuxAIO.sh (you got it from this step)
You can simply type .die in the server you have your NadekoBot to make her restart.

Restarting Nadeko with the Server:

Open PuTTY and login as you have before, type reboot and press Enter.

Restarting Manually:

  • Kill your previous session, check with tmux ls
  • tmux kill-session -t nadeko (don't forget to replace "nadeko" to what ever you named your bot's session)
  • Run the bot again.

Updating Nadeko

  • Connect to the terminal through PuTTY.
  • tmux kill-session -t nadeko (don't forget to replace nadeko in the command with the name of your bot's session)
  • Make sure the bot is not running.
  • tmux new -s nadeko (nadeko is the name of the session)
  • cd ~ && wget -N https://github.com/Kwoth/NadekoBot-BashScript/raw/1.9/linuxAIO.sh && bash linuxAIO.sh
  • Choose 1 to update the bot with latest build available.
  • Next, choose either 2 or 3 to run the bot again with normally or auto restart respectively.
  • Done.

Additional Information

tmux
  • If you want to see the sessions after logging back again, type tmux ls, and that will give you the list of sessions running.
  • If you want to switch to/ see that session, type tmux a -t nadeko (nadeko is the name of the session we created before so, replace “nadeko” with the session name you created.)
  • If you want to kill NadekoBot session, type tmux kill-session -t nadeko
Setting up SFTP
  • Open WinSCP
  • Click on New Site (top-left corner).
