Install Multicraft on Ubuntu Server
This article is for those looking for a detailed and straightforward guide on installing Multicraft on Ubuntu Server.
Multicraft is a complete Minecraft server hosting solution.
In this guide, we will consider the case when you already have a server with the Ubuntu Server 22.04 LTS operating system installed on it.
You can read more about how to install Ubuntu Server 22.04 LTS in my guide “Install Ubuntu Server 22.04 LTS”.
In addition, OpenSSH must be installed on the server, and port 22 must be open in order to be able to connect to the server using the SSH protocol.
To install OpenSSH on a server, you can use the command:
sudo apt install openssh-serverIf you plan to connect to the server using the Windows operating system, you can use PuTTY or MobaXterm.
This guide describes how to connect to a server using the iTerm2 terminal emulator installed on the macOS operating system.
Please note that you will need to open the following TCP ports to access your server:
- TCP port 80 - to get a free cryptographic certificate through Let’s Encrypt CA.
- TCP port 443 - to access the Multicraft control panel.
- TCP port 25565 - for Minecraft client access to the Minecraft server.
Note that port 25565 is used by default to connect a Minecraft client to a Minecraft server, but you can use other ports to run multiple Minecraft servers.
For example, the first Minecraft server launched with Multicraft will use port 25581; the second server, launched with Multicraft, will use port 25582, and so on. In this case, the Minecraft client will need to specify not only the IP address or name of the Minecraft server but also the port through which to connect to the server. For example minecraft.heyvaldemar.net:25581.
We connect to the server on which you plan to install Multicraft.
To obtain and subsequently renew a free SSL certificate, we will use the Let’s Encrypt certification authority, as well as the Certbot software client, which is designed to make it as easy as possible to obtain and renew a certificate through the Let’s Encrypt certification authority.
Update the local package index to the latest changes in the repositories using the command:
sudo apt update
Now let’s install the packages required for Multicraft to work using the command:
sudo apt install -y apache2 apt-transport-https certbot python3-certbot-apache mysql-server php libapache2-mod-php php-mysql php-gd php-cli php-common php-mbstring php-ldap php-odbc php-pear php-xml php-xmlrpc php-bcmath php-pdo default-jdk git zip unzipPlease note that in this tutorial, MySQL will be used as a database management system, and Apache will be used as a webserver.
Let’s configure Apache for further work with the Multicraft control panel.
We enable the Apache webserver module called “rewrite” using the command:
sudo a2enmod rewriteNote that the “rewrite” module is one of the most commonly used modules in the Apache webserver and provides a flexible and powerful way to manipulate URLs.
Now you need to make changes to the Apache configuration file by opening it in a text editor using the command:
sudo vim /etc/apache2/apache2.conf
Press the “i” button to switch to edit mode, find the “AllowOverride” parameter for the “/var/www/” directory, and set the “All” value for the parameter.
Please note, “AllowOverride All” - indicates that “.htaccess” should be used for the root directory of the virtual host and all subfolders.
Now press the “Esc” button to exit edit mode, then type “:x” and press the “Enter” button to save your changes and exit the editor.
Now you need to create a virtual host file (called a block in Nginx), with which the Multicraft control panel will work in the future.
Let’s create a virtual host file using a text editor using the command:
sudo vim /etc/apache2/sites-available/multicraft.heyvaldemar.net.confIn this manual, the multicraft.heyvaldemar.net subdomain will be used to access the Multicraft control panel from the Internet. You will need to specify your domain or subdomain by which your Multicraft control panel will be available from the Internet.
Hit the “i” button to go into edit mode, then insert the following configuration for the webserver to work.
In this manual, the multicraft.heyvaldemar.net subdomain will be used to access the Multicraft control panel from the Internet. You will need to specify your domain or subdomain by which your Multicraft control panel will be available from the Internet.
Now press the “Esc” button to exit edit mode, then type “:x” and press the “Enter” button to save your changes and exit the editor.
We activate the created virtual host using the command:
sudo a2ensite multicraft.heyvaldemar.net.confIn this manual, the multicraft.heyvaldemar.net subdomain will be used to access the Multicraft control panel from the Internet. You will need to specify your domain or subdomain by which your Multicraft control panel will be available from the Internet.
Deactivate the default virtual host using the command:
sudo a2dissite 000-default.conf
Verify that there are no errors in the syntax of the new Apache config file using the command:
sudo apache2ctl configtest
Restart Apache to apply the changes made using the command:
sudo systemctl restart apache2
Let’s check that Apache has started successfully using the command:
sudo systemctl status apache2
Now, in order to increase the security level of the webserver, it is necessary to obtain a cryptographic certificate for the domain or subdomain, through which the Multicraft control panel will be accessible from the Internet.
To obtain and subsequently renew a free SSL certificate, we will use the Let’s Encrypt certification authority, as well as the Certbot software client, which is designed to make it as easy as possible to obtain and renew a certificate through the Let’s Encrypt certification authority.
In this manual, the multicraft.heyvaldemar.net subdomain will be used to access the Multicraft control panel from the Internet. You will need to specify your domain or subdomain by which your Multicraft control panel will be available from the Internet.
Request a cryptographic certificate using the command:
sudo certbot --apache -d multicraft.heyvaldemar.net
Next, we indicate the email address to which Let’s Encrypt will send notifications about the expiration of the cryptographic certificate and press the “Enter” button.
The next step is to read and accept the terms of use of the services provided.
Press the button “a”, then “Enter”, if you agree with the terms of use of the services provided.
The next step is to choose whether you would like to share the above email address with the Electronic Frontier Foundation in order to receive newsletters.
Press the “n” button, then “Enter”.
At the next stage, you need to choose: do you want the parameters to be automatically added to the Apache configuration file for automatically redirecting HTTP traffic to HTTPS.
Press the button “2”, then “Enter”.
Please note that cryptographic certificates obtained through Let’s Encrypt CA are valid for ninety days. Certbot automatically adds a script to renew the certificate to the task scheduler and the script runs twice a day, automatically renewing any cryptographic certificate that expires within thirty days.
You can check the functionality of the cryptographic certificate renewal process using the command:
sudo certbot renew --dry-run
Now let’s configure MySQL for further work with the Multicraft control panel.
First, you need to run the “mysql_secure_installation” script, which is designed to provide a basic level of MySQL security.
Run the script using the command:
sudo mysql_secure_installation
Next, you need to answer a few questions to ensure a basic level of MySQL security.
The first question is whether you want to use the password strength plugin, which will need to be set later for the “root” user who has administrator rights in MySQL.
Press the “y” button, then “Enter”.
The next step is to select the level of password complexity checking, which will need to be set later for the “root” user who has administrator rights in MySQL.
In this tutorial, we will look at the highest level of password strength checking for the “root” user.
Press the button “2”, then “Enter”.
The next step is to provide a strong password for the “root” user who has administrator rights in MySQL.
Specify a strong password for the “root” user and press the “Enter” button.
Next, specify the password for the “root” user again and press the “Enter” button.
The next question is if you would like to proceed to the next step in setting up a basic MySQL security level with the obtained password strength value.
Please note that if the password you specified will have a value of “Estimated strength of the password” less than 100, it means that the password you specified earlier for the “root” user is not strong enough, and you need to specify a stronger password.
In this tutorial, the “Estimated strength of the password” value is 100, which indicates that the previously specified password is strong enough.
Press the “y” button, then “Enter”.
The next question is if you want to delete anonymous users.
Press the “y” button, then “Enter”.
The next question is if you want to disable remote MySQL connectivity for the “root” user.
Press the “y” button, then “Enter”.
The next question is if you want to drop the test databases.
Press the “y” button, then “Enter”.
Now you need to apply the changes you made.
Press the “y” button, then “Enter”.
Now you need to create databases that will be used by the Multicraft control panel and the Multicraft daemon in the future, as well as users with the necessary rights in these databases.
We connect to the MySQL management console using the command:
sudo mysql -u root -p
Specify the password for the “root” account specified earlier and press the “Enter” button.
In this manual, “multicraft_panel” will be used as the database name for the Multicraft control panel.
Let’s create a database, which will be used by the Multicraft control panel in the future, using the command:
CREATE DATABASE multicraft_panel CHARACTER SET utf8 COLLATE utf8_general_ci;
In this manual, “multicraftpaneldbuser” with the password “c7_Qm,A+;eq}=UHq5yW” will be used as the username with rights to the database for the Multicraft control panel.
Create a user and assign a password to it using the command:
CREATE USER 'multicraftpaneldbuser'@'localhost' IDENTIFIED BY 'c7_Qm,A+;eq}=UHq5yW';
We grant the new user rights to the previously created database using the command:
GRANT ALL ON multicraft_panel.* TO 'multicraftpaneldbuser'@'localhost';
This tutorial will use “multicraft_daemon” as the database name for the Multicraft daemon.
Let’s create a database that will be used by the Multicraft daemon in the future using the command:
CREATE DATABASE multicraft_daemon CHARACTER SET utf8 COLLATE utf8_general_ci;
In this manual, “multicraftdaemondbuser” with the password “zkJ3Xpr7f>/TLSYw6Zk” will be used as the username with rights to the database for the Multicraft daemon.
Create a user and assign a password to it using the command:
CREATE USER 'multicraftdaemondbuser'@'localhost' IDENTIFIED BY 'zkJ3Xpr7f>/TLSYw6Zk';
We grant the new user rights to the previously created database using the command:
GRANT ALL ON multicraft_daemon.* TO 'multicraftdaemondbuser'@'localhost';
Apply the changes made using the command:
FLUSH PRIVILEGES;
Disconnect from the MySQL Management Console using the command:
quit
Now download the “multicraft.tar.gz” archive containing the files for installing Multicraft using the command:
sudo wget http://www.multicraft.org/download/linux64 -O multicraft.tar.gz
Unpack the downloaded archive “multicraft.tar.gz” using the command:
sudo tar xvzf multicraft.tar.gz
Let’s go to the “multicraft” folder using the command:
cd multicraft
Now let’s run the Multicraft installation script using the command:
sudo ./setup.sh
Next, you need to answer a few questions from the Multicraft installer.
The first question is whether you need to run each Minecraft server using a separate user.
Press the “y” button, then “Enter”.

Press the “n” button, then “Enter”.
The next step is to specify a database management system that will be used to work with the Multicraft daemon.
This tutorial will use MySQL as the database management system.
Specify “mysql”, then press the “Enter” button.
At the next stage, you need to specify the IP address of the server on which the database for the Multicraft daemon is located.
In this tutorial, the database for the Multicraft daemon is located on the same server as the Multicraft control panel.
Leave the default value and press the “Enter” button.
In the next step, you need to specify the name assigned to the database for the Multicraft daemon, which was created earlier.
This tutorial uses “multicraft_daemon” as the database name for the Multicraft daemon.
Leave the default value and press the “Enter” button.
At the next stage, you need to specify the name assigned to the user who was created earlier and to whom the rights to the database were granted for the Multicraft daemon to work.
In this tutorial, “multicraftdaemondbuser” is used as the database username for the Multicraft daemon.
Specify “multicraftdaemondbuser”, then press the “Enter” button.
At the next stage, you need to specify the password assigned to the user who was granted rights to the database for the Multicraft daemon to work.
