# 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
