Anonymity Setting up your own Matrix Server.

[Fixxx]

In this article, we will consider setting up your own Matrix server for communication.
To create your own server you need a dedicated server and a domain linked to server.
In this example Ubuntu 22.04 will be used as the operating system. So let's get started.

Connect to the server via SSH, update the packages and install the necessary packages with the following command:

sudo apt install curl wget gnupg2 apt-transport-https -y​

Add the GPG key for Matrix Synapse with the following command:

undefined​

Add the Matrix Synapse repository with the following command:

echo "deb [signed-by=/usr/share/keyrings/matrix-org-archive-keyring.gpg] https://packages.matrix.org/debian/
$(lsb_release -cs) main" | tee /etc/apt/sources.list.d/matrix-org.list​

Install Matrix Synapse with the following commands:

sudo apt-get update​

sudo apt-get install matrix-synapse-py3​

In the opened window, enter the address of our site in the format matrix.sitename.domainname.
In the next window select "<No>, Matrix Synapse is installed". Start the service with the following commands:

​

sudo systemctl start matrix-synapse​

sudo systemctl enable matrix-synapse​

Now it's necessary to configure Matrix Synapse. Generate a secret key with the following command:

cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1​

Copy the output value. Open the server configuration file with the command:

sudo nano /etc/matrix-synapse/homeserver.yaml​

Change the following lines:

bind_addresses: ['127.0.0.1']​

enable_registration: true​

registration_shared_secret: "paste the value from the previous command"​

Save the changes and restart the service with the following command:

sudo systemctl restart matrix-synapse​

Next, let's set up a reverse proxy on Nginx. Install Nginx:

sudo apt-get install nginx​

Create an Nginx configuration file:

sudo nano /etc/nginx/conf.d/matrix.conf​

Add the following lines to this file:

server {​

listen 80;​

server_name sitename.domainname; #your website address​

location / {​

proxy_pass http://localhost:8008;​

proxy_set_header X-Forwarded-For $remote_addr;​

}​

}​

Save the changes and check the configuration with the following command:

nginx -t​

If everything is correct, restart the service with the following command:

sudo systemctl restart nginx​

Create a root user on our server with the following command:

register_new_matrix_user -c /etc/matrix-synapse/homeserver.yaml http://localhost:8008​

Enter a username, then enter the password twice.
When prompted to make admin type yes and press Enter.
Enable Let's Encrypt. Install Certbot with the following command:

sudo apt install certbot python3-certbot-nginx​

Enter the following command to configure the SSL certificate:

certbot --nginx -d your_domain​

Enter your e-mail and agree to the service's rules. Next step: enter Y if you want to receive email newsletters from EEF.
Then check the functionality of your server by visiting your site, where an image with the text [matrix] will be displayed.

This completes the installation: you can register an account and start communicating.
