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

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:

$ sudo -u postgres createuser -P peertube
$ sudo -u postgres createdb -O peertube 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 && cd versions

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

$ sudo -u peertube wget -q "https://github.com/Chocobozzz/PeerTube/releases/download/${VERSION}/peertube-${VERSION}.zip"
$ sudo -u peertube unzip peertube-${VERSION}.zip && sudo -u peertube rm peertube-${VERSION}.zip

Install Peertube:

$ cd ../ && 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 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 configuration.

PeerTube does not support webserver host change. Keep in mind your domain name is definitive after your first PeerTube start.

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

Then modify the webserver configuration file. Please pay attention to the alias keys of the static locations. It should correspond to the paths of your storage directories (set in the configuration file inside the storage key).

$ 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 vim /etc/nginx/sites-available/peertube # Comment ssl_certificate and ssl_certificate_key lines
$ sudo certbot --authenticator standalone --installer nginx --post-hook "systemctl start nginx"
$ sudo vim /etc/nginx/sites-available/peertube # Uncomment ssl_certificate and ssl_certificate_key lines
$ sudo systemctl reload nginx

Remember your certificate will expire in 90 days, and thus needs renewal.

Now you have the certificates you can reload nginx:

$ sudo systemctl reload nginx

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

$ sudo pkg install dehydrated

TCP/IP Tuning

On Linux

$ 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/

Update the service file:

$ 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

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

Administrator

The administrator password is automatically generated and can be found in the logs. You can 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:

• Subscribe to the mailing list for PeerTube administrators: https://framalistes.org/sympa/subscribe/peertube-admin
• Add you instance to the public PeerTube instances index if you want to: https://instances.peertu.be/
• Check available CLI tools

Upgrade

PeerTube instance

Check the changelog (in particular BREAKING CHANGES!): https://github.com/Chocobozzz/PeerTube/blob/develop/CHANGELOG.md

Auto (minor versions only)

The password it asks is PeerTube's database user password.

$ cd /var/www/peertube/peertube-latest/scripts && sudo -H -u peertube ./upgrade.sh

Manually

Make a SQL backup

$ SQL_BACKUP_PATH="backup/sql-peertube_prod-$(date -Im).bak" && \
    cd /var/www/peertube && sudo -u peertube mkdir -p backup && \
    sudo -u postgres pg_dump -F c peertube_prod | sudo -u peertube tee "$SQL_BACKUP_PATH" >/dev/null

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"

Download the new version and unzip it:

$ cd /var/www/peertube/versions && \
    sudo -u peertube wget -q "https://github.com/Chocobozzz/PeerTube/releases/download/${VERSION}/peertube-${VERSION}.zip" && \
    sudo -u peertube unzip -o peertube-${VERSION}.zip && \
    sudo -u peertube rm peertube-${VERSION}.zip

Install node dependencies:

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

Copy new configuration defaults values and update your configuration file:

$ sudo -u peertube cp /var/www/peertube/versions/peertube-${VERSION}/config/default.yaml /var/www/peertube/config/default.yaml
$ diff /var/www/peertube/versions/peertube-${VERSION}/config/production.yaml.example /var/www/peertube/config/production.yaml

Change the link to point to the latest version:

$ cd /var/www/peertube && \
    sudo unlink ./peertube-latest && \
    sudo -u peertube ln -s versions/peertube-${VERSION} ./peertube-latest

nginx

Check changes in nginx configuration:

$ cd /var/www/peertube/versions
$ diff "$(ls --sort=t | head -2 | tail -1)/support/nginx/peertube" "$(ls --sort=t | head -1)/support/nginx/peertube"

systemd

Check changes in systemd configuration:

$ cd /var/www/peertube/versions
$ diff "$(ls --sort=t | head -2 | tail -1)/support/systemd/peertube.service" "$(ls --sort=t | head -1)/support/systemd/peertube.service"

Restart PeerTube

If you changed your nginx configuration:

$ sudo systemctl reload nginx

If you changed your systemd configuration:

$ sudo systemctl daemon-reload

Restart PeerTube and check the logs:

$ sudo systemctl restart peertube && sudo journalctl -fu peertube

Things went wrong?

Change peertube-latest destination to the previous version and restore your SQL backup:

$ OLD_VERSION="v0.42.42" && SQL_BACKUP_PATH="backup/sql-peertube_prod-2018-01-19T10:18+01:00.bak" && \
    cd /var/www/peertube && sudo -u peertube unlink ./peertube-latest && \
    sudo -u peertube ln -s "versions/peertube-$OLD_VERSION" peertube-latest && \
    sudo -u postgres pg_restore -c -C -d postgres "$SQL_BACKUP_PATH" && \
    sudo systemctl restart peertube
