Darkhttpd is a simple, fast HTTP 1.1 web server for static content. It does not support PHP or CGI etc but is designed to serve static content, which it does very well. Darkhttpd would be an excellent alternative to Lighttpd for running an Alpine mirror
For a full list of features see the darkhttpd homepage
Install
apk add darkhttpd
Configure
Default location of files to serve: /var/www/localhost/htdocs
Default log path: /var/log/darkhttpd/access.log
There's no configuration file for darkhttpd, everything is controlled from the command line or in our case the OpenRC init file, which is stored in /etc/init.d/darkhttpd and by default looks like this:
#! /sbin/runscript description="darkhttpd web server" command="/usr/bin/darkhttpd" command_args="${document_root:-/var/www/localhost/htdocs} --chroot --daemon --uid darkhttpd --gid www-data --log /var/log/darkhttpd/access.log" procname="darkhttpd" pidfile="" stopsig="SIGTERM"
So by default we will serve pages from /var/www/localhost/htdocs and darkhttpd will run as a background daemon, chrooted to /var/www/localhost/htdocs with a user of darkhttpd
and group of www-data
.
Logs will go to /var/log/darkhttpd/access.log.
The default values have been chosen to provide sane, secure settings.
Change any of these values as you see fit, but it's a good idea to backup the file before making changes.
For a full list of available options, run:
darkhttpd
and amend the command_args
line as you see fit.
For example, you might wish to serve files from /var/files instead, so you can edit the /etc/init.d/darkhttpd file with an editor of your choice (vi, nano, vim or whatever) and make it like so:
#! /sbin/runscript description="darkhttpd web server" command="/usr/bin/darkhttpd" command_args="/var/files --chroot --daemon --uid darkhttpd --gid www-data --log /var/log/darkhttpd/access.log" procname="darkhttpd" pidfile="" stopsig="SIGTERM"
Use
Filesharing is made easy; simply add your files under the server root, by default /var/www/localhost/htdocs
Test
Create a test page under the server root, by default /var/www/localhost/htdocs
echo "this is a test page" > /var/www/localhost/htdocs/index.html
Start the daemon:
rc-service darkhttpd start
Output should be something like this:
* Starting darkhttpd ... darkhttpd/1.9, copyright (c) 2003-2013 Emil Mikulic. listening on: http://0.0.0.0:80/ chrooted to `/var/www/localhost/htdocs' set gid to 82 set uid to 100
Now point a browser to your darkhttpd server and you should get the index page, or a directory listing if you didn't create an index page.
Check the logfile:
tail /var/log/darkhttpd/access.log
Controlling darkhttpd status
Stop, start and restart the daemon in the usual fashion:
rc-service darkhttpd start
rc-service darkhttpd stop
rc-service darkhttpd restart
Auto-start darkhttpd at boot
To add the daemon to the default runlevel so it auto-starts at boot, do:
rc-update add darkhttpd
Troubleshooting
- When restarting the daemon you may see an error message:
Stopping darkhttpd ... /lib/rc/sh/runscript.sh: line 202: can't create /sys/fs/cgroup/openrc/darkhttpd/tasks: nonexistent directory Starting darkhttpd ...
This error message appears to be benign and of no consequence so can be ignored. I can only replicate this error on a VMWare vSphere client.
- If the daemon will not start, ensure you haven't made a syntax error in the init script.
- Ensure the daemon is running with
rc-status
- Make use of the logs to check it is receiving requests. To do this, run
tail -f /var/log/darkhttpd/access.log
and then send requests to the web server. If darkhttpd is receiving the requests, lines will be logged. If you don't see these lines, perhaps a firewall rule is blocking access to the server or there is a routing issue somewhere?
Use 'Ctrl C' to exit back to the prompt when finished testing.
man darkhttpd
darkhttpd/1.12, copyright (c) 2003-2016 Emil Mikulic. usage: darkhttpd /path/to/wwwroot [flags] flags: --port number (default: 8080, or 80 if running as root) Specifies which port to listen on for connections. Pass 0 to let the system choose any free port for you. --addr ip (default: all) If multiple interfaces are present, specifies which one to bind the listening port to. --maxconn number (default: system maximum) Specifies how many concurrent connections to accept. --log filename (default: stdout) Specifies which file to append the request log to. --chroot (default: don't chroot) Locks server into wwwroot directory for added security. --daemon (default: don't daemonize) Detach from the controlling terminal and run in the background. --index filename (default: index.html) Default file to serve when a directory is requested. --no-listing Do not serve listing if directory is requested. --mimetypes filename (optional) Parses specified file for extension-MIME associations. --default-mimetype string (optional, default: application/octet-stream) Files with unknown extensions are served as this mimetype. --uid uid/uname, --gid gid/gname (default: don't privdrop) Drops privileges to given uid:gid after initialization. --pidfile filename (default: no pidfile) Write PID to the specified file. Note that if you are using --chroot, then the pidfile must be relative to, and inside the wwwroot. --no-keepalive Disables HTTP Keep-Alive functionality. --forward host url (default: don't forward) Web forward (301 redirect). Requests to the host are redirected to the corresponding url. The option may be specified multiple times, in which case the host is matched in order of appearance. --forward-all url (default: don't forward) Web forward (301 redirect). All requests are redirected to the corresponding url. --no-server-id Don't identify the server type in headers or directory listings. --ipv6 Listen on IPv6 address.
