Installing Lighttpd
Lighttpd is available as a package
pkg_add lighttpd
Choose the version with just lighttpd, likely option 1
Configure
Config file is at /etc/lighttpd.conf
Lighttpd will be chrooted to /var/www so config paths are relative to that.
Change server.document-root to `"/htdocs/"
Check that the service will start
rcctl -df start lighttpd
You may see the following error on OpenBSD 6.4 or greater.
daemonized server failed to start; check error log for details
And the /var/www/logs/error.log shows:
2023-05-06 18:37:43: (configfile.c.1771) opening /dev/null failed: No such file or directory
2023-05-06 18:37:43: (server.c.1584) Opening errorlog failed. Going down.
The reason is the chroot to /var/www, which means /dev/null is no longer visible to the process. You have
to make a fake /dev/null.
Luckily, I found a post on daemonforums which linked to the the solution on Reddit.
The steps I followed were 1-4 from that post. There was no nodev restriction for /var
1. change into that directory
```
# cd /var/lighttpd/chroot/
```
2. create a dev/ directory in there
```
# mkdir dev
```
3. set the permissions on it
```
# chmod 755 dev
# chown root:wheel dev
```
4. make the expected null device in there and make it world-accessible
```
mknod dev/null c 2 2
chmod 666 dev/null
```
Re-running the rcctl start command was successful.
Next, enable lighttpd to start at boot
rcctl enable lighttpd
