Its name is a portmanteau of "light" and "httpd": lighttpd is a simple, standards-compliant, secure, and flexible web server.
lighttpd is a powerful server, made long ago to handle upwards of 10,000 connections in parallel on one server. It was used in wikipedia server a long time ago and also some google services.
General information
| Feature/Artifact | Value/Name | Observations |
|---|---|---|
| Main package name | lighttpd | apk add lighttpd
|
| Manpages and DOCs packages | lighttpd-doc | apk add lighttpd-doc
|
| Configuration file | /etc/lighttpd/lighttpd.conf | A vanilla default configuration |
| Html place for system pages | /var/www/localhost/htdocs/ | Each web server in alpine has own path for that |
| Dynamic files (cache, extra) | /var/lib/lighttpd/ | Created dynamically, each server in alpine has own path for that |
| Log files (error, access, etc) | /var/log/lighttpd/ | Each web server in alpine has own path for that |
| User running the webserver | lighttpd | Others Linux used "www-data" alpine has as a group |
| Group to common to webserver | www-data | Used to share things amont others daemons or services, like redis or apache files |
| Programed on | C and lua | Main engine code in C, modules and config in Lua variants |
Important Limitations
Some common hosting panels do not handle lighttpd configuration management.
No HTTP/3 support.
As we read previously.. main purpose was handle several request on one server, so are focused on high load.
As main front end web server are perfect and it's recommended as reverse proxy server for apache2 or nginx.
Install Lighttpd
The installation works out of the box for static pages. After installing you can see webserver in action by putting any file inside the /var/www/localhost/htdocs/ directory.
Per user web files are supported by default in /home/<user>/public_html directory by default if we enable it (process are described below in further section "Lighttpd configuration".
lighttpd is available in the Alpine Linux repositories. To install, simple launch the commands below:
apk add lighttpd rc-update add lighttpd default rc-service lighttpd restart
Testing Lighttpd
This section is assuming that lighttpd is running. If you now launch a web browser from a remote system and point it to your web server, you will see a page that says "404 - Not Found". Well, at the moment there is no content available but the server is up and running.
Let's add a simple test page to get rid of the "404 - Not Found page":
echo '<!DOCTYPE html><html><head><title>✔️</title><meta charset="utf-8"></head><body>Lighttpd is running!</body></html>' > /var/www/localhost/htdocs/index.html
For testing open a browser and go to http://127.0.0.1/ and you should see "Lighttpd is running!". Note the example usage of "127.0.0.1" indicating that the lighttpd server and the web browser are running on the same machine.
If you are using alpine remotely, open a browser on your client machine, and go to http://<webserveripaddres>/. The "webserveripaddres" is the IP address of your lighttpd server machine.
Lighttpd Configuration
If you just want to serve simple HTML pages lighttpd can be used out-of-box. No further configuration needed.
For production purposes the Production LAMP system: Lighttpd + PHP + MySQL wiki page will explain in details all the needs, there's the Production Lets Encrypt: dehydrated wiki page with futher information to use HTTPS and lets encrypt certificates.
Due to the minimalism of alpine linux, unfortunately the lighttpd packaging only provided vanilla configurations not close to alpine or easy admin maintenance, see the Production LAMP system: Lighttpd + PHP + MySQL wiki page to goin in deep about configuring lighttpd web server.
Controlling Lighttpd
Start lighttpd: After the installation lighttpd is not running. As we made in first section was started already but if you want to start lighttpd manually use:
rc-service lighttpd start
You will get a feedback about the status.
* Caching service dependencies [ ok ] * Starting lighttpd... [ ok ]
Stop lighttpd: If you want to stop the web server use stop in the same way of previous command:
rc-service lighttpd stop
Restart lighttpd: After changing the configuration file lighttpd needs to be restarted.
rc-service lighttpd restart
Proper Runlevel: By default no services are added to start process, sysadmin must know what we want and what will services do, also other main reason are due in dockers there's no runlevels per se and Alpine linux are mostly used in dockers containers. You must added the servide only to the default runlevel, not to boot, because need networking activated
rc-update add lighttpd default

In production web, LAMP means Linux + Apache + Mysql + Php installed and integrated, but today the "A" of apache are more used as Nginx or Lighttpd, and the "M" of MySQL are more used as Mariadb, the LAMP focused documents are:
