Installing Pterodactyl for Plesk

Pterodactyl is a software for managing game servers. As it’s still in development, installing it in some environments is not straight-forward. You should read the official docs along. The guide is written for Plesk with CentOS but could be helpful for other panel users like cPanel too.

Web host/Plesk configuration

WARNING: According to Pterodactyl MySQL 5 should still work, however I run into issues. You need MINIMUM MariaDB 10.2 (10.1 is too old, too). If mysql --version reports not 10.2 or higher, you will have to use this tutorial to upgrade your database.

Read very carefully. Especially if you are not that experienced with Linux. Don’t copy-paste multiple lines into the console; and think about what you are doing. I use CentOS 7/8 for this tutorial, but it can be easily applied to Ubuntu by simply googling the respective commands. If you are not comfortable with this, you probably should not try to use this panel.

Log into to your SSH console (we start with root) and install the Redis and PHP packages. Here are the commands for CentOS (the epel repository is a requirement on CentOS 7 for Redis):

# for CentOS 7
yum install epel-release

yum update
yum install redis
plesk installer --select-release-current --install-component php7.4
yum install plesk-php74-redis plesk-php74-cli plesk-php74-bcmath plesk-php74-gd plesk-php74-mbstring plesk-php74-mysql plesk-php74-pdo plesk-php74-xml

Start redis and enable autostart:

systemctl start redis
systemctl enable redis

Log into Plesk, go to Domain -> Add Domain (even if you use a subdomain like panel.example.com, click on Add Domain and not on Add Subdomain. This way you can separate the installation of your main homepage).

Type in the full URL of which it will be reached later and make sure to click on Secure the domain with Let’s Encrypt. Remember the username and click on save.

Add Domain (click to enlarge)

Now we will have to modify some settings on the domain. Go to Web Hosting Access and change Access to the server over SSH to /bin/bash. Also remember the username (gamepanel in this case), you will have to SU into it later.

Web Hosting Access

Go to Hosting Settings and set the document root to httpdocs/public and change PHP Support to 7.4 and run as FPM application served by nginx.

Hosting settings

Go to Apache & Nginx Settings, turn off Proxy Mode and write into additional NGINX directives:

sendfile off;
index index.php;
location = / {
	try_files $uri $uri/ /index.php?$query_string;
}

location ~ / {
	try_files $uri $uri/ /index.php?$query_string;
}
Apache & nginx settings

You should now create a new database for the panel in the Databases menu (Domain -> Databases (in the menu on the right side) -> Add Database). And remember its configuration. Don’t forget to check “Allow remote connections”.

Installing Pterodactyl

For security reasons and simply because we don’t want to get any permission problems later, we won’t work with root.

(It’s also a little paradox that the official wiki goes through the installation with root, as the Panel advertises with its security. Working with root, especially for beginners, is never safe).

Download and Configuration

While creating your domain/webspace you had to provide a user and a password. SU into that user with su yourusernameforvhost (I named it gamepanel in the screenshots). And simply type cd to get to the home directory.

Create a temporary alias for the PHP-command (you will have to do this each time, you open a ssh session or SU into an user):
PHP7=/opt/plesk/php/7.4/bin/php

Install composer locally into the vhost by typing:

curl -sS https://getcomposer.org/installer | $PHP7 -- --install-dir=. --filename=composer

Download and extract Pterodactyl and set permissions:

# Set this to the version you want to install. Look into the docs (see link at the beginning of this post)
PTEROVERSION=v1.1.1

cd httpdocs

# Delete old Plesk default index files
rm ./public/index.html ./index.html

curl -Lo panel.tar.gz https://github.com/pterodactyl/panel/releases/download/$PTEROVERSION/panel.tar.gz
tar xzvf panel.tar.gz

# Correct permissions of caches
chmod -R u+w storage/*
chmod -R u+w bootstrap/cache

# Correct permissions of all files
# folders
find . -type d -exec chmod g+rx {} +
find . -type d -exec chmod o+rx {} +
# files
find . -type f -exec chmod g+r {} +
find . -type f -exec chmod o+r {} +

Run composer:

cp .env.example .env
$PHP7 ../composer install --no-dev --optimize-autoloader

Run the configuration commands as stated in the wiki, but with the Plesk PHP installation. When asked for a database backend, use always the recommended one (Redis / MariaDB). And when asked for MariaDB user credentials, insert the ones you used while creating the database with Plesk:

# Run the first command only, when doing a **NEW** installation (not an upgrade)
$PHP7 artisan key:generate --force

# Choose redis there
$PHP7 artisan p:environment:setup

# Insert the database credentials you created in plesk
$PHP7 artisan p:environment:database

# Choosing SMTP with localhost should work automatically then
$PHP7 artisan p:environment:mail

$PHP7 artisan migrate --seed --force

# Create admin user
$PHP7 artisan p:user:make

You don’t need to set the user for permissions, as we didn’t work with root.

The panel should be available, you can try by going to your panels website.

Troubleshooting: If the panel is not available

If you’re just getting a white page, or a error 500, do a ls -l and make sure, that the files are owned by the user you set (e.g. gamepanel) and have the group psacln. Then make sure that files can be read by everyone (e.g. -rw-r–r–.) and folders can be accessed by everyone (e.g. drwxr-xr-x.); this seems to be a requirement by Plesk. Don’t do a chmod 777!

If there are still issues, look into the folder logs in the home directory of the user. E.g. cd && cd logs then look into the file error_log and especially into the file proxy_error_log

Setting up workers

Go back to Plesk and select your panel domain. Go to Scheduled Tasks (on the right side) and click on Add Task. Choose Script Path and use as file httpdocs/artisan and with arguments schedule:run

Under Run select Cron Style and type in * * * * *.

The following Screenshot shows the old method with Run a Command (which is fine too).

Scheduled Tasks

Click on Run Now to test it. Click then on OK.

Setting up SystemD unit

Make sure, that you are still inside SSH. If you’re still in the user, go back to root by typing exit.

As root, enable systemd of your user:

# Replace with the name of your gamepanel ssh user
BASHUSER=gamepanel

loginctl enable-linger $BASHUSER

# now go back to the user
su $BASHUSER
cd # go to home
# Set User ENV for systemd
echo XDG_RUNTIME_DIR=/run/user/$(id -ru) > .bashrc
source .bashrc

# This command now should return running
systemctl --user status

If the last command was successful, you can proceed.

If it is NOT successful, then there is a problem enabling SystemD for your user. In this case, you can create a system-wide daemon: https://pterodactyl.io/panel/1.0/getting_started.html#create-queue-worker. There you would have to use for user the user you created in plesk (e.g. gamepanel), for group use pscln and you would have to replace /usr/bin/php with the php path as done before in this tutorial. The path to artisan must be of course replaced, too.

You must now still be inside the gamepanel bash user. Create a systemd user file:

mkdir -p .config/systemd/user
touch .config/systemd/user/pteroq.service

Into this file .config/systemd/user/pteroq.service insert following:

[Unit]
Description=Pterodactyl Queue Worker User

[Service]
Restart=always
ExecStart=/opt/plesk/php/7.4/bin/php %h/httpdocs/artisan queue:work --queue=high,standard,low --sleep=3 --tries=3

[Install]
WantedBy=default.target

Now start and enable the service with the following command:

systemctl daemon-reload --user
systemctl enable --now pteroq.service --user

Now typing in systemctl status pteroq.service --user should return that it is running successfully.

Installing the Daemon

Proceed to the Wings Docs. I don’t recommend installing the daemon on the same (v)server where Plesk is installed!

When you found an error in my documentation write a comment. You can also write me on Discord: Sapd#4930

    1. Denis Arnst

      Simply repeat the chapter “Download and Configuration” but stop AFTER run composer install.

      Then do
      $PHP7 php artisan view:clear
      $PHP7 artisan config:clear
      $PHP7 artisan migrate –seed –force

      1. I tried with ubuntu 18.04. pterodactyl v1.6.3. not worked

        error is : No application encryption key has been specified.

  1. Hey there great work on keeping this updated. I am having a port binding issue maybe you could help me with. I do have the daemon on the same server. I have tried changing the ports to unused ones then get a binding error in the browser console. Any ideas would be great.
    Thanks.

  2. Hey, the onstallation complete sucessfull but if i open my Petrodactyl Domain, i see only the Plesk default page.

  3. Hi Denis,

    i do it like your how to but try to install the latest version 1.0.0 Beta Release 2. But i get some strange error. After artisan migrate command the tables were created but in the end i get this error.

    SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the
    manual that corresponds to your MariaDB server version for the right syntax to use near ‘json null aft
    er `server_id`’ at line 1 (SQL: alter table `subusers` add `permissions` json null after `server_id`)

    MariaDB: mysql Ver 15.1 Distrib 5.5.65-MariaDB, for Linux (x86_64) using readline 5.1
    Actual Plesk Version also

    i hope you have an idea 😉

  4. Really nice guide, but I’ve been pulling my hair out since last year because for some reason NGINX decides that it won’t load common file extensions (txt, png, jpeg, etc), even though I have the directives set correctly. Any ideas?

    1. Some directive is wrong.
      Open up ptero, open the browser console -> network -> Reload the site. Then see if the resources are 404 errors or 500.
      If 500, check the logs, if 404 make sure the location directives are correct (you can also take a look in the logs, it will point to where it searches for the file usually).

  5. hey in the beginning code you have an error, that confused the shit out of me 😀
    yum install redisplesk installer –select-release-current –install-component php7.2
    there is no space between redis and plesk 😀

    1. Oh yeah, you’re right I fixed it, thank you.

      But it’s not a white space missing, but a new line, so these are two separate commands:
      yum install redis
      plesk installer –select-release-current –install-component php7.2

    1. I just preferred nginx only in this case.
      With proxy mode it works like this:
      User request <-> nginx <-> apache

      It should theoretically work with proxy mode on too, you would have to leave “Additional nginx directives” empty then.

  6. so i am using a physical server with plesk and would like to install dameon on it can i just install docker through my panel as it gives me that option

    1. I would install Docker by hand. I am not sure how the docker option in the panel works, I guess it is specially designed for hosting. Installing by hand (package manager) has no disadvantages.

      It’s btw better when you partition the physical server into vservers (e.g. with Proxmox) and run Plesk and the gameservers on two different vservers.
