How to setup a Pleroma instance.

Pleroma is a simple and lightweight way to install your own ActivityPub / Mastodon instance on your server.

Step 0: Requirements

Step 1: Install dependencies

First let’s install dependencies:

apt install curl unzip libncurses5 postgresql postgresql-contrib nginx certbot libmagic-dev
apt install imagemagick ffmpeg libimage-exiftool-perl

Step 2: Create a Pleroma user

Simple run:

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

Step 3: Download Pleroma

We can now download the Pleroma binaries and move them:

su pleroma -s $SHELL

curl '' -o ~/

mv release/* .
rm -r release/

Step 4: Create directories

Now let’s create the different directories pleroma require and set the ownership of the folder to “pleroma”.

exit # Exit the pleroma user
mkdir -p /var/lib/pleroma/uploads
mkdir -p /var/lib/pleroma/static
mkdir -p /etc/pleroma

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

Step 5: Run the scripts

You can now run the built-in scripts to setup the config, setup the database and test it.

su pleroma -s $SHELL # Login as pleroma
./bin/pleroma_ctl instance gen --output /etc/pleroma/config.exs --output-psql /tmp/setup_db.psql # Auto-Configure
psql -f /tmp/setup_db.psql # Setup the database
./bin/pleroma_ctl migrate # Migrate the database

Now let’s test everything worked properly:

./bin/pleroma daemon
sleep 20 && curl http://localhost:4000/api/v1/instance
./bin/pleroma stop
exit # Logout the pleroma user

Step 6: Configure nginx

Pleroma has a default nginx config file you can use as template:

cp /opt/pleroma/installation/pleroma.nginx /etc/nginx/sites-available/pleroma.conf
ln -s /etc/nginx/sites-available/pleroma.conf /etc/nginx/sites-enabled/pleroma.conf
nano /etc/nginx/sites-available/pleroma.conf

In that file simply replace all occurences of domain.tld by your actual domain, example:

Once that’s done, simply save and exit the file. Then type the following command to restart nginx:

systemctl restart nginx

Step 7: Create the service file for Pleroma

Now to manage Pleroma, we can use the default service file (systemd), no edit required.

cp /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service
systemctl start pleroma
systemctl enable pleroma

Step 8: Create an admin user

Let’s create an admin user now.

./bin/pleroma_ctl user new <username> <username>@<your domain name> --admin

Then simply go on the url that’s provided by that command to change your password.

Step 9: Use Pleroma

You now have a working instance of Pleroma. To use it simply connect using your user.

You can change your profile settings in the settings gear on the top right of the page.

Then you need to follow other instances of other servers, if you don’t, there will be no content. The “Known Network” is based on all your follows. Note you also won’t have the old content of accounts, only the new ones.

This is a quick guide to understand the different timelines in Pleroma (or Mastodon in general)
