# Dependencies

## Debian / Ubuntu and derivatives
  1. On a fresh Debian/Ubuntu, as root user, install basic utility programs needed for the installation

```
# apt-get install curl sudo unzip vim
```

  2. It would be wise to disable root access and to continue this tutorial with a user with sudoers group access

  3. Install certbot (choose instructions for nginx and your distribution) :
     [https://certbot.eff.org/all-instructions](https://certbot.eff.org/all-instructions)
  4. Install NodeJS 8.x (current LTS):
     [https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions](https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions)
  5. Install yarn, and be sure to have a recent version (>= 1.5.1, the latest release):
     [https://yarnpkg.com/en/docs/install#linux-tab](https://yarnpkg.com/en/docs/install#linux-tab)
  6. Run:

```
$ sudo apt update
$ sudo apt install nginx ffmpeg postgresql postgresql-contrib openssl g++ make redis-server git
$ ffmpeg -version # Should be >= 3.x
$ g++ -v # Should be >= 5.x
```

If you still have a 2.x version of FFmpeg on Ubuntu:
```
$ sudo add-apt-repository ppa:jonathonf/ffmpeg-3
$ sudo apt-get update
$ sudo apt install ffmpeg
```

Now that dependencies are installed, before running PeerTube you should start PostgreSQL and Redis:
```
$ sudo systemctl start redis postgresql
```

## Arch Linux

  1. Run:

```
$ sudo pacman -S nodejs yarn ffmpeg postgresql openssl redis git wget unzip python2 base-devel npm nginx
```

Now that dependencies are installed, before running PeerTube you should start PostgreSQL and Redis:
```
$ sudo systemctl start redis postgresql
```

## CentOS 7

  1. Install NodeJS 8.x (current LTS):
     [https://nodejs.org/en/download/package-manager/#enterprise-linux-and-fedora](https://nodejs.org/en/download/package-manager/#enterprise-linux-and-fedora)
  2. Install yarn:
     [https://yarnpkg.com/en/docs/install](https://yarnpkg.com/en/docs/install)
  3. Install or compile ffmpeg:
     * Install - [https://linoxide.com/linux-how-to/install-ffmpeg-centos-7/](https://linoxide.com/linux-how-to/install-ffmpeg-centos-7/)
     * Compile - [https://gist.github.com/mustafaturan/7053900#file-latest-ffmpeg-centos6-sh](https://gist.github.com/mustafaturan/7053900#file-latest-ffmpeg-centos6-sh)
  4. Run:

```
$ sudo yum update
$ sudo yum install epel-release centos-release-scl
$ sudo yum update
$ sudo yum install nginx postgresql postgresql-server postgresql-contrib openssl gcc-c++ make redis git devtoolset-7
```

  5. You need to use a more up to date version of G++ in order to run the yarn install command, hence the installation of devtoolset-7.
```
$ sudo scl enable devtoolset-7 bash
```

Later when you invoke any node command, please prefix them with `CC=/opt/rh/devtoolset-7/root/usr/bin/gcc CXX=/opt/rh/devtoolset-7/root/usr/bin/g++`, such as with:

```
$ sudo -H -u peertube CC=/opt/rh/devtoolset-7/root/usr/bin/gcc CXX=/opt/rh/devtoolset-7/root/usr/bin/g++ yarn install --production --pure-lockfile
```

Now that dependencies are installed, before running PeerTube you should start PostgreSQL and Redis:
```
$ sudo service redis start
$ sudo service postgresql start
```

## Fedora

0. Upgrade your packages:
```
dnf upgrade
```
1. Add a user with sudoers group access:
```
useradd my-peertube-user
passwd my-peertube-user
usermod my-peertube-user -a -G wheel	# Add my-peertube-user to sudoers
su my-peertube-user
```
2. (Optional) Install certbot (choose instructions for nginx and your distribution) :
[https://certbot.eff.org/all-instructions](https://certbot.eff.org/all-instructions)
3. Install NodeJS 8.x (current LTS):
[https://nodejs.org/en/download/package-manager/#enterprise-linux-and-fedora](https://nodejs.org/en/download/package-manager/#enterprise-linux-and-fedora)
4. Install yarn:
[https://yarnpkg.com/en/docs/install](https://yarnpkg.com/en/docs/install)
5. Enable [RPM Fusion](https://rpmfusion.org) for Fedora (available for x86, x86_64, armhfp)
```
sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
```
This is necessary because `ffmpeg` is not in the Fedora repos.

6. Run:
```
sudo dnf install nginx ffmpeg postgresql-server postgresql-contrib openssl gcc-c++ make redis git
ffmpeg -version # Should be >= 3.x
g++ -v # Should be >= 5.x
```
7. Post-installation

_from [PostgreSQL documentation](https://www.postgresql.org/download/linux/redhat/):_
> Due to policies for Red Hat family distributions, the PostgreSQL installation will not be enabled for automatic start or have the database initialized automatically.
```
# PostgreSQL
sudo postgresql-setup initdb
sudo systemctl enable postgresql.service
sudo systemctl start postgresql.service
# Nginx
sudo systemctl enable nginx.service
sudo systemctl start nginx.service
# Redis
sudo systemctl enable redis.service
sudo systemctl start redis.service
```
8. Firewall

By default, you cannot acces your server via public IP. To do so, you must configure firewall:
```
# Ports used by peertube dev setup
sudo firewall-cmd --permanent --zone=public --add-port=3000/tcp
sudo firewall-cmd --permanent --zone=public --add-port=9000/tcp
# Optional
sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
# Reload firewall
sudo firewall-cmd --reload
```
9. Configure max ports

This is necessary if you are running dev setup, otherwise you will have errors with `nodemon`
```
echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
```

## FreeBSD

On a fresh install of [FreeBSD](https://www.freebsd.org), new system or new jail:

  1. bootstrap pkg, initialize db and install peertube's dependencies, always as root (sudo not yet installed):
```
# pkg
# pkg update
# pkg install -y sudo bash wget git python nginx pkgconf vips postgresql96-server postgresql96-contrib redis openssl node npm yarn ffmpeg unzip
```

  2. Allow users in the wheel group (hope you don't forgot to add your user on wheel group!) to use sudo
```
# visudo
```

     Uncomment the line 90
```
%wheel ALL=(ALL) ALL
```

  3. Enable nginx, redis, postgresql services and initialize database

```
# sysrc postgresql_enable="YES"
# sysrc redis_enable="YES"
# sysrc nginx_enable="YES"
```

	 Initialize database and start services
```
# service postgresql initdb
# service postgresql start
# service redis start
# service nginx start
```

## macOS
* Add the packages:

	```
	brew install ffmpeg nginx postgresql openssl gcc make redis git yarn
	```
* Run the services:

   ```
   brew services run postgresql
   brew services run redis
   ```

## Gentoo

* Add this to ``/etc/portage/sets/peertube``:
```
net-libs/nodejs
sys-apps/yarn
media-video/ffmpeg[x264] # Optionnally add vorbis,vpx
dev-db/postgresql
dev-db/redis
dev-vcs/git
app-arch/unzip
dev-lang/python:2.7
www-servers/nginx
media-libs/vips[jpeg,png,exif]

# Optionnal, client for Let’s Encrypt:
# app-crypt/certbot
# app-crypt/certbot-nginx
```

* Compile the peertube set:
```
emerge -a @peertube
```

* Initialize the PostgreSQL database if you just merged it:
```
emerge --config postgresql
```

* (For OpenRC) Enable and then start the services (replace with the correct PostgreSQL slot):
```
rc-update add redis
rc-update add postgresql-10
rc-service redis start
rc-service postgresql-10 start
```
