Installation

Please don’t install PeerTube for production on a device behind a low bandwidth connection (example: your ADSL link).
If you want information about the appropriate hardware to run PeerTube, please see the FAQ.

🔨 Dependencies

Follow the steps of the dependencies guide.

👷 PeerTube user

Create a peertube user with /var/www/peertube home:

sudo useradd -m -d /var/www/peertube -s /bin/bash -p peertube peertube

Set its password:

sudo passwd peertube

Ensure the peertube root directory is traversable by nginx:

ls -ld /var/www/peertube # Should be drwxr-xr-x

On FreeBSD

sudo pw useradd -n peertube -d /var/www/peertube -s /usr/local/bin/bash -m
sudo passwd peertube

or use adduser to create it interactively.

🗃️ Database

Create the production database and a peertube user inside PostgreSQL:

cd /var/www/peertube
sudo -u postgres createuser -P peertube

Here you should enter a password for PostgreSQL peertube user, that should be copied in production.yaml file.
Don’t just hit enter else it will be empty.

sudo -u postgres createdb -O peertube -E UTF8 -T template0 peertube_prod

Then enable extensions PeerTube needs:

sudo -u postgres psql -c "CREATE EXTENSION pg_trgm;" peertube_prod
sudo -u postgres psql -c "CREATE EXTENSION unaccent;" peertube_prod

📄 Prepare PeerTube directory

Fetch the latest tagged version of Peertube:

VERSION=$(curl -s https://api.github.com/repos/chocobozzz/peertube/releases/latest | grep tag_name | cut -d '"' -f 4) && echo "Latest Peertube version is $VERSION"

Open the peertube directory, create a few required directories:

cd /var/www/peertube
sudo -u peertube mkdir config storage versions
sudo -u peertube chmod 750 config/

Download the latest version of the Peertube client, unzip it and remove the zip:

cd /var/www/peertube/versions
# Releases are also available on https://builds.joinpeertube.org/release
sudo -u peertube wget -q "https://github.com/Chocobozzz/PeerTube/releases/download/${VERSION}/peertube-${VERSION}.zip"
sudo -u peertube unzip -q peertube-${VERSION}.zip && sudo -u peertube rm peertube-${VERSION}.zip

Install Peertube:

cd /var/www/peertube
sudo -u peertube ln -s versions/peertube-${VERSION} ./peertube-latest
cd ./peertube-latest && sudo -H -u peertube yarn install --production --pure-lockfile

🔧 PeerTube configuration

Copy the default configuration file that contains the default configuration provided by PeerTube.
You must not update this file.

cd /var/www/peertube
sudo -u peertube cp peertube-latest/config/default.yaml config/default.yaml

Now copy the production example configuration:

cd /var/www/peertube
sudo -u peertube cp peertube-latest/config/production.yaml.example config/production.yaml

Then edit the config/production.yaml file according to your webserver and database configuration. In particular:

• webserver: Reverse proxy public information
• secrets: Secret strings you must generate manually (PeerTube version >= 5.0)
• database: PostgreSQL settings
• redis: Redis settings
• smtp: If you want to use emails
• admin.email: To correctly fill root user email

Keys defined in config/production.yaml will override keys defined in config/default.yaml.

PeerTube does not support webserver host change. Even though PeerTube CLI can help you to switch hostname there’s no official support for that since it is a risky operation that might result in unforeseen errors.

🚚 Webserver

We only provide official configuration files for Nginx.

Copy the nginx configuration template:

sudo cp /var/www/peertube/peertube-latest/support/nginx/peertube /etc/nginx/sites-available/peertube

Set the domain for the webserver configuration file by replacing [peertube-domain] with the domain for the peertube server:

sudo sed -i 's/${WEBSERVER_HOST}/[peertube-domain]/g' /etc/nginx/sites-available/peertube
sudo sed -i 's/${PEERTUBE_HOST}/127.0.0.1:9000/g' /etc/nginx/sites-available/peertube

Then modify the webserver configuration file. Please pay attention to:

• the alias, root and rewrite directives paths, the paths must correspond to your PeerTube filesystem location
• the proxy_limit_rate and limit_rate directives if you plan to stream high bitrate videos (like 4K at 60FPS)

sudo vim /etc/nginx/sites-available/peertube

Activate the configuration file:

sudo ln -s /etc/nginx/sites-available/peertube /etc/nginx/sites-enabled/peertube

To generate the certificate for your domain as required to make https work you can use Let’s Encrypt:

sudo systemctl stop nginx
sudo certbot certonly --standalone --post-hook "systemctl restart nginx"
sudo systemctl reload nginx

Certbot should have installed a cron to automatically renew your certificate.
Since our nginx template supports webroot renewal, we suggest you to update the renewal config file to use the webroot authenticator:

# Replace authenticator = standalone by authenticator = webroot
# Add webroot_path = /var/www/certbot
sudo vim /etc/letsencrypt/renewal/your-domain.com.conf

If you plan to have many concurrent viewers on your PeerTube instance, consider increasing worker_connections value: https://nginx.org/en/docs/ngx_core_module.html#worker_connections.

If using FreeBSD

On FreeBSD you can use Dehydrated security/dehydrated for Let’s Encrypt

sudo pkg install dehydrated

⚗️ Linux TCP/IP Tuning

sudo cp /var/www/peertube/peertube-latest/support/sysctl.d/30-peertube-tcp.conf /etc/sysctl.d/
sudo sysctl -p /etc/sysctl.d/30-peertube-tcp.conf

Your distro may enable this by default, but at least Debian 9 does not, and the default FIFO
scheduler is quite prone to “Buffer Bloat” and extreme latency when dealing with slower client
links as we often encounter in a video server.

🧱 systemd

If your OS uses systemd, copy the configuration template:

sudo cp /var/www/peertube/peertube-latest/support/systemd/peertube.service /etc/systemd/system/

Check the service file (PeerTube paths and security directives):

sudo vim /etc/systemd/system/peertube.service

Tell systemd to reload its config:

sudo systemctl daemon-reload

If you want to start PeerTube on boot:

sudo systemctl enable peertube

Run:

sudo systemctl start peertube
sudo journalctl -feu peertube

If using FreeBSD

On FreeBSD, copy the startup script and update rc.conf:

sudo install -m 0555 /var/www/peertube/peertube-latest/support/freebsd/peertube /usr/local/etc/rc.d/
sudo sysrc peertube_enable="YES"

Run:

sudo service peertube start

If using OpenRC

If your OS uses OpenRC, copy the service script:

sudo cp /var/www/peertube/peertube-latest/support/init.d/peertube /etc/init.d/

If you want to start PeerTube on boot:

sudo rc-update add peertube default

Run and print last logs:

sudo /etc/init.d/peertube start
tail -f /var/log/peertube/peertube.log

🧑‍💻 Administrator

The administrator username is root and the password is automatically generated. It can be found in PeerTube
logs (path defined in production.yaml). You can also set another password with:

cd /var/www/peertube/peertube-latest && NODE_CONFIG_DIR=/var/www/peertube/config NODE_ENV=production npm run reset-password -- -u root

Alternatively you can set the environment variable PT_INITIAL_ROOT_PASSWORD,
to your own administrator password, although it must be 6 characters or more.

🎉 What now?

Now your instance is up you can:

• Add your instance to the public PeerTube instances index if you want to: https://instances.joinpeertube.org/
• Check available CLI tools

Upgrade

PeerTube instance

Check the changelog (in particular the IMPORTANT NOTES section): https://github.com/Chocobozzz/PeerTube/blob/develop/CHANGELOG.md

Run the upgrade script (the password it asks is PeerTube’s database user password):

cd /var/www/peertube/peertube-latest/scripts && sudo -H -u peertube ./upgrade.sh
sudo systemctl restart peertube # Or use your OS command to restart PeerTube if you don't use systemd

You may want to run sudo -u peertube yarn cache clean after several upgrades to free up disk space.

Prefer manual upgrade?

Make a SQL backup
