# Installing on CentOS 7
## Installation
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](https://www.digitalocean.com/community/tutorials/how-to-create-a-sudo-user-on-centos-quickstart). 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 $SHELL -c 'command'` instead.
### Required packages
* `postgresql` (9,6+, CentOS 7 comes with 9.2, we will install version 11 in this guide)
* `elixir` (1.5+)
* `erlang`
* `erlang-parsetools`
* `erlang-xmerl`
* `git`
* Development Tools
#### Optional packages used in this guide
* `nginx` (preferred, example configs for other reverse proxies can be found in the repo)
* `certbot` (or any other ACME client for Let’s Encrypt certificates)
### Prepare the system
* First update the system, if not already done:
```shell
sudo yum update
```
* Install some of the above mentioned programs:
```shell
sudo yum install wget git unzip
```
* Install development tools:
```shell
sudo yum group install "Development Tools"
```
### Install Elixir and Erlang
* Add the EPEL repo:
```shell
sudo yum install epel-release
sudo yum -y update
```
* Install Erlang repository:
```shell
wget -P /tmp/ https://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
sudo rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
```
* Install Erlang:
```shell
sudo yum install erlang erlang-parsetools erlang-xmerl
```
* Download [latest Elixir release from Github](https://github.com/elixir-lang/elixir/releases/tag/v1.8.1) (Example for the newest version at the time when this manual was written)
```shell
wget -P /tmp/ https://github.com/elixir-lang/elixir/releases/download/v1.8.1/Precompiled.zip
```
* Create folder where you want to install Elixir, we’ll use:
```shell
sudo mkdir -p /opt/elixir
```
* Unzip downloaded file there:
```shell
sudo unzip /tmp/Precompiled.zip -d /opt/elixir
```
* Create symlinks for the pre-compiled binaries:
```shell
for e in elixir elixirc iex mix; do sudo ln -s /opt/elixir/bin/${e} /usr/local/bin/${e}; done
```
### Install PostgreSQL
* Add the Postgresql repository:
```shell
sudo yum install https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-centos11-11-2.noarch.rpm
```
* Install the Postgresql server:
```shell
sudo yum install postgresql11-server postgresql11-contrib
```
* Initialize database:
```shell
sudo /usr/pgsql-11/bin/postgresql-11-setup initdb
```
* Open configuration file `/var/lib/pgsql/11/data/pg_hba.conf` and change the following lines from:
```plain
# IPv4 local connections:
host all all 127.0.0.1/32 ident
# IPv6 local connections:
host all all ::1/128 ident
```
to
```plain
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
```
* Enable and start postgresql server:
```shell
sudo systemctl enable --now postgresql-11.service
```
### Install PleromaBE
* Add a new system user for the Pleroma service:
```shell
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.
* Git clone the PleromaBE repository and make the Pleroma user the owner of the directory:
```shell
sudo mkdir -p /opt/pleroma
sudo chown -R pleroma:pleroma /opt/pleroma
sudo -Hu pleroma git clone -b stable https://git.pleroma.social/pleroma/pleroma /opt/pleroma
```
* Change to the new directory:
```shell
cd /opt/pleroma
```
* Install the dependencies for Pleroma and answer with `yes` if it asks you to install `Hex`:
```shell
sudo -Hu pleroma mix deps.get
```
* Generate the configuration: `sudo -Hu pleroma mix pleroma.instance gen`
* Answer with `yes` if it asks you to install `rebar3`.
* This may take some time, because parts of pleroma get compiled first.
* After that it will ask you a few questions about your instance and generates a configuration file in `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):
```shell
mv config/{generated_config.exs,prod.secret.exs}
```
* The previous command creates also the file `config/setup_db.psql`, with which you can create the database:
```shell
sudo -Hu postgres psql -f config/setup_db.psql
```
* Now run the database migration:
```shell
sudo -Hu pleroma MIX_ENV=prod mix ecto.migrate
```
* Now you can start Pleroma already
```shell
sudo -Hu pleroma MIX_ENV=prod mix phx.server
```
### Finalize installation
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.
#### Nginx
* Install nginx, if not already done:
```shell
sudo yum install nginx
```
* Setup your SSL cert, using your method of choice or certbot. If using certbot, first install it:
```shell
sudo yum install certbot-nginx
```
and then set it up:
```shell
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).
---
* Copy the example nginx configuration to the nginx folder
```shell
sudo cp /opt/pleroma/installation/pleroma.nginx /etc/nginx/conf.d/pleroma.conf
```
* Before starting nginx edit the configuration and change it to your needs (e.g. change servername, change cert paths)
* Enable and start nginx:
```shell
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:
```shell
sudo certbot certonly --email <your@emailaddress> -d <yourdomain> --webroot -w /var/lib/letsencrypt/
```
#### Other webserver/proxies
You can find example configurations for them in `/opt/pleroma/installation/`.
#### Systemd service
* Copy example service file
```shell
sudo cp /opt/pleroma/installation/pleroma.service /etc/systemd/system/pleroma.service
```
* Edit the service file and make sure that all paths fit your installation
* Enable and start `pleroma.service`:
```shell
sudo systemctl enable --now pleroma.service
```
#### Create your first user
If your instance is up and running, you can create your first user with administrative rights with the following task:
```shell
sudo -Hu pleroma MIX_ENV=prod mix pleroma.user new <username> <your@emailaddress> --admin
```

## Questions
Questions about the installation or didn’t it work as it should be, ask in [#pleroma:matrix.org](https://matrix.heldscal.la/#/room/#freenode_#pleroma:matrix.org) or IRC Channel **#pleroma** on **Freenode**.
