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.
Pleroma 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.
Pleroma will be run by a dedicated user, \_pleroma. Before creating it, insert the following lines in login.conf:
```
pleroma:\
:datasize-max=1536M:\
:datasize-cur=1536M:\
:openfiles-max=4096
```
This creates a "pleroma" 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 pleroma crash some time after starting.
Create the \_pleroma user, assign it the pleroma login class and create its home directory (/home/\_pleroma/): `useradd -m -L pleroma _pleroma`
Enter a shell as the \_pleroma user. As root, run `su _pleroma -;cd`. Then clone the repository with `git clone -b stable https://git.pleroma.social/pleroma/pleroma.git`. Pleroma is now installed in /home/\_pleroma/pleroma/, it will be configured and started at the end of this guide.
You will need to specify pgdata directory to the default (/var/postgresql/data) with the `-D <path>` and set the user to postgres with the `-U <username>` flag. This can be done as follows:
```
initdb -D /var/postgresql/data -U postgres
```
If you are not using the default directory, you will have to update the `datadir` variable in the /etc/rc.d/postgresql script.
When this is done, enable postgresql so that it starts on boot and start it. As root, run:
```
rcctl enable postgresql
rcctl start postgresql
```
To check that it started properly and didn't fail right after starting, you can run `ps aux | grep postgres`, there should be multiple lines of output.
Do not forget to change *<IPv4/6 address\>* to your server's address(es). If httpd should only listen on one protocol family, comment one of the two first *listen* options.
Replace *<domain name\>* by the domain name you'll use for your instance. As root, run `acme-client -n` to check the config, then `acme-client -ADv <domain name>` to create account and domain keys, and request a certificate for the first time.
Make acme-client run everyday by adding it in /etc/daily.local. As root, run the following command: `echo "acme-client <domain name>" >> /etc/daily.local`.
Relayd will look for certificates and keys based on the address it listens on (see next part), the easiest way to make them available to relayd is to create a link, as root run:
# Forward some paths to the local server (as pleroma won't respond to them as you might want)
pass request quick path "/robots.txt" forward to <httpd_server>
# Append a bunch of headers
match request header append "X-Forwarded-For" value "$REMOTE_ADDR" # This two header and the next one are not strictly required by pleroma but adding them won't hurt
match request header append "X-Forwarded-By" value "$SERVER_ADDR:$SERVER_PORT"
match response header append "X-XSS-Protection" value "1; mode=block"
match response header append "X-Permitted-Cross-Domain-Policies" value "none"
match response header append "X-Frame-Options" value "DENY"
match response header append "X-Content-Type-Options" value "nosniff"
match response header append "Referrer-Policy" value "same-origin"
match response header append "X-Download-Options" value "noopen"
match response header append "Content-Security-Policy" value "default-src 'none'; base-uri 'self'; form-action 'self'; img-src 'self' data: https:; media-src 'self' https:; style-src 'self' 'unsafe-inline'; font-src 'self'; script-src 'self'; connect-src 'self' wss://CHANGEME.tld; upgrade-insecure-requests;" # Modify "CHANGEME.tld" and set your instance's domain here
match request header append "Connection" value "upgrade"
#match response header append "Strict-Transport-Security" value "max-age=31536000; includeSubDomains" # Uncomment this only after you get HTTPS working.
# If you do not want remote frontends to be able to access your Pleroma backend server, comment these lines
match response header append "Access-Control-Allow-Origin" value "*"
match response header append "Access-Control-Allow-Methods" value "POST, PUT, DELETE, GET, PATCH, OPTIONS"
match response header append "Access-Control-Allow-Headers" value "Authorization, Content-Type, Idempotency-Key"
match response header append "Access-Control-Expose-Headers" value "Link, X-RateLimit-Reset, X-RateLimit-Limit, X-RateLimit-Remaining, X-Request-Id"
# Stop commenting lines here
}
relay wwwtls {
listen on $ext_inet port https tls # Comment to disable listening on IPv4

protocol plerup

forward to <httpd_server> port 80 check http "/robots.txt" code 200
Again, change *<IPv4/6 address\>* to your server's address(es) and comment one of the two *listen* options if needed. Also change *wss://CHANGEME.tld* to *wss://<your instance's domain name\>*.
Replace *<network interface\>* by your server's network interface name (which you can get with ifconfig). Consider replacing the content of the authorized\_ssh\_clients macro by, for exemple, your home IP address, to avoid SSH connection attempts from bots.
* run `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.
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 pleroma at boot
An rc script to automatically start pleroma at boot hasn't been written yet, it can be run ina tmux session (tmux is in base).
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**.
