* Suggest TCP/IP CoDel and BBR congestion control in production guide This seems to be helping lots on my server, where the default (Debian 9) was to use FIFO queueing which would cause buffer bloat and huge latency for clients on slower network links.

## 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](https://github.com/Chocobozzz/PeerTube/blob/develop/FAQ.md#should-i-have-a-big-server-to-run-peertube).
|
|
|
|
### Dependencies
|
|
|
|
**Follow the steps of the [dependencies guide](dependencies.md).**
|
|
|
|
### 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](https://letsencrypt.org/):
|
|
|
|
```
|
|
$ 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](https://dehydrated.io/) `security/dehydrated` for [Let's Encrypt](https://letsencrypt.org/)
|
|
|
|
```
|
|
$ 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 cp /var/www/peertube/peertube-latest/support/freebsd/peertube /usr/local/etc/rc.d/
|
|
$ sudo chmod +x /usr/local/etc/rc.d/peertube
|
|
$ sudo echo peertube_enable="YES" >> /etc/rc.conf
|
|
```
|
|
|
|
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
|
|
```
|
|
|
|
### 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/
|
|
|
|

|
|
```
|
|
$ 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 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
|
|
```
