sudo apt install wget curl gnupg2 ca-certificates lsb-release gnupg zip libncurses5 libmagic-dev -y

In the next step, you need to install PostgreSQL. So you can add the official PostgreSQL repository to the Ubuntu resource list by running the following command:

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

Then you need to add the repository GPG key:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

Now you need to update the list of system packages by running the following command:

sudo apt update

sudo ufw allow OpenSSH

You also need to do the same for the HTTP and HTTPS ports:

sudo ufw allow 80
sudo ufw allow 443

Install Pleroma on Ubuntu 20.04 | Ubuntu 18.04

After successfully completing the previous steps, now we come to how to install Pleroma. Just follow the steps below step by step. In this article, we are going to install Pleroma from the OTP version. So in the first step, you have to create a Pleroma user without the ability to log in. It should also be noted that the following command creates a home directory in /opt/pleroma.

sudo adduser --system --shell /bin/false --home /opt/pleroma pleroma

Before going to the Pleroma user, you need to go to the root user by executing the following commands:

sudo su
su pleroma -s $SHELL -l

Now it’s time to download Pleroma to a temporary location using the following command

curl "https://git.pleroma.social/api/v4/projects/2/jobs/artifacts/stable/download?job=amd64" -o /tmp/pleroma_amd64.zip

Then you have to extract the downloaded file with the following command:

unzip /tmp/pleroma_amd64.zip -d /tmp/

Now you can easily install Pleroma:

mv /tmp/release/* /opt/pleroma

In the next step after installing Pleroma, you need to delete the temporary files:

rm -rf /tmp/pleroma_amd64.zip /tmp/release

You can now switch to the root user by executing the exit command:

exit

Another important point is that in the next step you need to create a directory for the uploads and public files:

mkdir -p /var/lib/pleroma/{uploads,static}

You can create a Pleroma configuration list using the following command:

mkdir -p /etc/pleroma

Finally, you can change the ownership of Pleroma directories to Pleroma users by running the following command:

chown -R pleroma /var/lib/pleroma /etc/pleroma

How to Configure Pleroma on Ubuntu 20.04

After you are fully acquainted with how to install Pleroma in the previous section, we now want to configure it. You must first return to the Pleroma user using the following command:

su pleroma -s /bin/bash -l

Use the following command to generate a Pleroma sample configuration file:

./bin/pleroma_ctl instance gen --output /etc/pleroma/config.exs --output-psql /tmp/setup_db.psql

You will be asked questions. You can ignore these questions if no error occurs. Note that you need to choose a strong password for your database. If you want to configure your instance from the admin panel, select “y” for the configuration storage question in the database.

In this step, you must go to the default PostgreSQL user created when installing PostgreSQL by executing the following commands:

exit
su postgres -s /bin/bash -l

You can then create a database using the SQL file:

psql -f /tmp/setup_db.psql

After you have successfully created the database, you need to return to the Pleroma user by executing the following commands:

exit
su pleroma -s /bin/bash -l

Finally, you can run the following commands to initialize the database we just created and go to the root user:

./bin/pleroma_ctl migrate
exit

In this section, you need to configure Nginx before launching Pleroma. You can install Nginx by moving it to the /etc/nginx/sites-available directory.

mv /opt/pleroma/installation/pleroma.nginx /etc/nginx/sites-available/pleroma.conf

Then you need to replace all the example.tld events with your domain in the next step using the following command:

sed -i 's/example\.tld/example.com/g' /etc/nginx/sites-available/pleroma.conf

Now you need to open the configuration file for editing using a text editor like nano:

nano /etc/nginx/sites-available/pleroma.conf

Now you should uncomment the location ~ /\.well-known/acme-challenge block. The server block of your configuration file should look like the following:

server {  server_name example.com;    listen 80;  listen [::]:80;    location ~ /\.well-known/acme-challenge {  root /var/lib/letsencrypt/;  }    location / {  return 301 https://$server_name$request_uri;  }  }

After making the changes, you can use the Ctrl+X key combination to save the file and exit it.

It’s time to enable the Pleroma Nginx configuration by running the following command:

ln -s /etc/nginx/sites-available/pleroma.conf /etc/nginx/sites-enabled/pleroma.conf

You must also enable the Nginx server with the following command to start it at boot time:

systemctl enable nginx
systemctl start nginx

Note that you need to install the Pleroma systemd service unit file in the distribution. To do this, use the following command:

mv /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service

Finally, you can enable and start the Pleroma service by executing the following commands:

systemctl enable pleroma
