Greetings, Dev! Do you want to host your own Mastodon server? If so, you’ve come to the right place. In this article, we’ll show you how to host a Mastodon server with detailed steps, tips, and tricks. Whether you’re a developer, a sysadmin or just a tech enthusiast, you’ll find everything you need to get started.
What Is Mastodon?
If you’re not familiar with Mastodon, it’s a free and open-source social networking software that allows you to create your own social network, just like Twitter. Mastodon is gaining more and more popularity, especially among users who are concerned about privacy and data ownership.
Mastodon is based on ActivityPub, an emerging standard for decentralized social networks. It’s designed to be user-friendly, scalable, and secure. Mastodon’s federated architecture means that you can create your own Mastodon instance and connect with other instances across the web.
Why Host Your Own Mastodon Server?
Hosting your own Mastodon server gives you complete control over your data and your network. You don’t have to rely on a third-party service to manage your social network. You can customize your server to meet your needs, and you can invite others to join your network.
Hosting your own Mastodon server also means that you can avoid the risks of centralized social networks, such as data breaches, censorship, and algorithmic manipulation. You can create a safer and more inclusive space for your community.
Getting Started: Requirements
Before you start hosting your own Mastodon server, you need to make sure your system meets the following requirements:
Requirement |
Description |
|---|---|
Operating System |
Linux (Ubuntu 18.04 or later recommended) |
Processor |
64-bit |
Memory |
At least 2GB RAM (4GB or more recommended) |
Storage |
At least 10GB free space (SSD recommended) |
Network |
A domain name and a static IP address |
Operating System
The first requirement for hosting your own Mastodon server is a Linux operating system. While it’s possible to install Mastodon on other platforms, such as macOS or Windows, we recommend using Ubuntu 18.04 or later for the best compatibility and support.
Ubuntu is a popular and user-friendly Linux distribution that comes with many preinstalled packages and tools. It’s also easy to set up and manage, even if you’re not a Linux expert.
If you don’t have a Linux system yet, you can download Ubuntu from the official website and install it on your computer or server. There are many tutorials and guides available online that can help you with the installation process.
Processor
Mastodon requires a 64-bit processor to run. This means that your system should have a modern CPU that supports 64-bit instructions. Most CPUs manufactured in the last decade support 64-bit, so this should not be a problem for most users.
However, if you’re using an older computer or a low-power device, such as a Raspberry Pi, you may need to check if it supports 64-bit. You can usually find this information on the manufacturer’s website or by running a command like `uname -a` on your Linux system.
Memory
Mastodon needs at least 2GB of RAM to run smoothly, but we recommend using 4GB or more for better performance. This is because Mastodon has many background processes and services that consume memory, such as the database, the web server, and the streaming server.
If your system has less than 2GB of RAM, you may experience slow performance, crashes, or other issues. You can check your system’s memory usage by running a command like `free -h` on your Linux system.
Storage
Mastodon requires at least 10GB of free disk space to store its data and files. We recommend using an SSD (solid-state drive) instead of an HDD (hard disk drive) for better I/O performance, especially if you expect high traffic or frequent database updates.
If your storage space is limited, you can reduce the disk usage by configuring Mastodon to delete old media files or limit the maximum file size. You can also use external storage solutions, such as Amazon S3 or Google Cloud Storage, to store the media files offsite.
Network
Mastodon needs a domain name and a static IP address to be accessible from the internet. You can register a domain name from a registrar, such as Namecheap or GoDaddy, and point it to your server’s IP address using DNS (domain name system).
You can check your server’s IP address by running a command like `ip addr show` on your Linux system. Make sure that your IP address is static (not dynamically assigned) to avoid DNS errors or IP blacklisting. You can usually configure your IP address via your router’s settings or your hosting provider’s control panel.
Installing Mastodon
Once you’ve met the requirements, you’re ready to install Mastodon on your server. Mastodon has several components that need to be installed and configured, including: Ruby, Node.js, PostgreSQL, Redis, and Nginx.
Fortunately, Mastodon comes with a script called `mastodon-install` that automates most of the installation process. You can download the script from the Mastodon GitHub repository and run it on your Linux system.
Step 1. Download the Mastodon source code
The first step is to download the Mastodon source code from the GitHub repository. You can use the `git` command to clone the repository to your local directory:
git clone https://github.com/tootsuite/mastodon.git mastodoncd mastodonThis will download the latest Mastodon code to the `mastodon` directory on your system.
Step 2. Run the `mastodon-install` script
The next step is to run the `mastodon-install` script, which will guide you through the installation process. This script will install all the required dependencies, configure the database, and set up the web server.
sudo ./bin/setupThis may take a few minutes to complete, depending on your system’s configuration and internet speed. Make sure that you have sudo privileges or run the script as the root user.
Step 3. Configure Mastodon settings
After the installation is complete, you need to configure Mastodon’s settings, such as the database credentials, the email settings, and the domain name. You can edit the `.env.production` file in the root directory to customize the settings:
nano .env.productionMake sure to set the correct values for each variable, such as the database name, user, and password, the email SMTP server, and the domain name. You can find more information about these settings in the Mastodon documentation.
Step 4. Build and start Mastodon
The final step is to build and start Mastodon. You can use the following commands to build the assets and start the services:
RAILS_ENV=production bundle exec rails assets:precompilesudo systemctl start mastodon-web mastodon-sidekiq mastodon-streamingThe `assets:precompile` command compiles the static assets, such as the CSS and JavaScript files, into a single file for faster loading. The `systemctl start` command starts the Mastodon services, including the web server, the background worker, and the streaming server.
You can now access your Mastodon instance by visiting your domain name in a web browser. Congratulations! You’ve just hosted your own Mastodon server!
