This guide is a step-by-step installation guide for CentOS 7. It also assumes that you have administrative rights, either as root or a user with sudo permissions. If you want to run this guide with root, ignore the sudo
at the beginning of the lines, unless it calls a user like sudo -Hu pleroma
; in this case, use su <username> -s $SHELL -c 'command'
instead.

sudo systemctl enable --now postgresql-11.service
sudo useradd -r -s /bin/false -m -d /var/lib/pleroma -U pleroma
Note: To execute a single command as the Pleroma system user, use sudo -Hu pleroma command
. You can also switch to a shell by using sudo -Hu pleroma $SHELL
. If you don’t have and want sudo
on your system, you can use su
as root user (UID 0) for a single command by using su -l pleroma -s $SHELL -c 'command'
and su -l pleroma -s $SHELL
for starting a shell.
sudo mkdir -p /opt/pleroma
sudo chown -R pleroma:pleroma /opt/pleroma
sudo -Hu pleroma git clone -b master https://git.pleroma.social/pleroma/pleroma /opt/pleroma
cd /opt/pleroma
yes
if it asks you to install Hex
:sudo -Hu pleroma mix deps.get
Generate the configuration: sudo -Hu pleroma mix pleroma.instance gen
yes
if it asks you to install rebar3
.config/generated_config.exs
.Check the configuration and if all looks right, rename it, so Pleroma will load it (prod.secret.exs
for productive instance, dev.secret.exs
for development instances):
mv config/{generated_config.exs,prod.secret.exs}
config/setup_db.psql
, with which you can create the database:sudo -Hu postgres psql -f config/setup_db.psql
sudo -Hu pleroma MIX_ENV=prod mix ecto.migrate
sudo -Hu pleroma MIX_ENV=prod mix phx.server
If you want to open your newly installed instance to the world, you should run nginx or some other webserver/proxy in front of Pleroma and you should consider to create a systemd service file for Pleroma.
sudo yum install nginx
sudo yum install certbot-nginx
and then set it up:
sudo mkdir -p /var/lib/letsencrypt/
sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --standalone
If that doesn’t work, make sure, that nginx is not already running. If it still doesn’t work, try setting up nginx first (change ssl “on” to “off” and try again).
sudo cp /opt/pleroma/installation/pleroma.nginx /etc/nginx/conf.d/pleroma.conf
sudo systemctl enable --now nginx
If you need to renew the certificate in the future, uncomment the relevant location block in the nginx config and run:
sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --webroot -w /var/lib/letsencrypt/
You can find example configurations for them in /opt/pleroma/installation/
.
sudo cp /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service
pleroma.service
:sudo systemctl enable --now pleroma.service
If your instance is up and running, you can create your first user with administrative rights with the following task:
sudo -Hu pleroma MIX_ENV=prod mix pleroma.user new <username> <your@emailaddress> --admin
Questions about the installation or didn’t it work as it should be, ask in #pleroma:matrix.org or IRC Channel #pleroma on Freenode.
