# Installing on OpenBSD
This guide describes the installation and configuration of akkoma (and the required software to run it) on a single OpenBSD 6.6 server.
This guide describes the installation and configuration of akkoma (and the required software to run it) on a single OpenBSD 7.2 server.
For any additional information regarding commands and configuration files mentioned here, check the man pages [online](https://man.openbsd.org/) or directly on your server with the man command.

To install them, run the following command (with doas or as root):
```
pkg_add elixir gmake git postgresql-server postgresql-contrib cmake ffmpeg ImageMagick erlang-wx-25
pkg_add elixir gmake git postgresql-server postgresql-contrib cmake ffmpeg erlang-wx libmagic
pkg_add erlang-wx # Choose the latest version as package version when promted
```
(Note that the erlang version may change, it was 25 at the time of writing)
Akkoma requires a reverse proxy, OpenBSD has relayd in base (and is used in this guide) and packages/ports are available for nginx (www/nginx) and apache (www/apache-httpd). Independently of the reverse proxy, [acme-client(1)](https://man.openbsd.org/acme-client) can be used to get a certificate from Let's Encrypt.

Akkoma will be run by a dedicated user, `_akkoma`. Before creating it, insert the following lines in `/etc/login.conf`:
```
akkoma:\

This creates a "akkoma" login class and sets higher values than default for datasize and openfiles (see [login.conf(5)](https://man.openbsd.org/login.conf)), this is required to avoid having akkoma crash some time after starting.

Enter a shell as `_akkoma` (as root `su _akkoma -`) and enter akkoma's installation directory (`cd ~/akkoma/`).
Then follow the main installation guide:
* run `mix deps.get`
* run `MIX_ENV=prod mix pleroma.instance gen` and enter your instance's information when asked
* copy config/generated\_config.exs to config/prod.secret.exs. The default values should be sufficient but you should edit it and check that everything seems OK.
* copy `config/generated_config.exs` to `config/prod.secret.exs`. The default values should be sufficient but you should edit it and check that everything seems OK.
* exit your current shell back to a root one and run `psql -U postgres -f /home/_akkoma/akkoma/config/setup_db.psql` to setup the database.
* return to a \_akkoma shell into akkoma's installation directory (`su _akkoma -;cd ~/akkoma`) and run `MIX_ENV=prod mix ecto.migrate`
* return to a `_akkoma` shell into akkoma's installation directory (`su _akkoma -;cd ~/akkoma`) and run `MIX_ENV=prod mix ecto.migrate`
As \_akkoma in /home/\_akkoma/akkoma, you can now run `LC_ALL=en_US.UTF-8 MIX_ENV=prod mix phx.server` to start your instance.
As `_akkoma` in `/home/_akkoma/akkoma`, you can now run `LC_ALL=en_US.UTF-8 MIX_ENV=prod mix phx.server` to start your instance.
In another SSH session/tmux window, check that it is working properly by running `ftp -MVo - http://127.0.0.1:4000/api/v1/instance`, you should get json output. Double-check that *uri*'s value is your instance's domain name.
##### Starting akkoma at boot
An rc script to automatically start akkoma at boot hasn't been written yet, it can be run in a tmux session (tmux is in base).
#### Create administrative user
If your instance is up and running, you can create your first user with administrative rights with the following command as the \_akkoma user.
