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.
#### Creating the pleroma user
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 headerappend "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
listen on $ext_inet6 port https tls # Comment to disable listening on IPv6
protocol plerup
forward to <pleroma_server> port 4000 check http "/" code 200
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 in a tmux session (tmux is in base).
