• apt-get install lighttpd
• Modify /etc/lighttpd/lighttpd.conf
  • set server.document-root to “/home/usr/www”, and “sudo chown www-data:www-data /home/usr/www”
• start it

sudo /etc/init.d/lighttpd start

• Test it by browser “http://rabi.chem.purdue.edu”
• Modify /etc/passwd

#www-data:x:33:33:www-data:/var/www:/usr/sbin/nologin
www-data:x:33:33:www-data:/home/usr/www:/bin/bash

• Note that required packages: pcre (for compiling only)
• Follow the instruction in https://www.howtoforge.com/tutorial/install-lighttpd-with-php-fpm-and-mysql-on-debian/
• Note: 1) keep only two lines in fastcgi.server's body as shown; 2) apt-get install php5-mysqlnd php5-xcache; 3) to reload we can type either “/etc/init.d/xxx restart” or “systemctl restart xxx.service”

• ref
• Install php from slackpkg
• Uncomment “include conf.d/fastcgi.conf” in /etc/lighttpd/modules.conf.
• In the fastcgi section of /etc/lighttpd/lighttpd.conf, copy the following lines below the extisting commented out

fastcgi config.

fastcgi.server = ( ".php" =>
  ( "localhost" =>
    (
    "socket" => "/tmp/php-fastcgi.socket",
    "bin-path" => "/usr/bin/php-cgi -c /etc/lighttpd/php.ini"
    )
  )
)

• Change the group of /var/lib/php from “apache” to “nobody”. Otherwise php won't be able to use $_SESSION.
• Test it by browser “http://rabi.chem.purdue.edu/test.php”. If it does not work, make sure first you can run php from command line.
• Note that required packages: libmcrypt, sqlite, net-snmp, t1lib

DokuWiki will run just fine with Lighttpd and PHP through FastCGI.

1. create /etc/dokuwiki/lighttpd.conf
2. cd /etc/lighttpd/conf-available
3. ln /etc/dokuwiki/lighttpd.conf 50-dokuwiki.conf

   1. /etc/lighttpd/conf-available/50-dokuwiki.conf -> /etc/dokuwiki/lighttpd.conf 

4. enable config with lighttpd-enable-mod dokuwiki
5. /etc/init.d/lighttpd force-reload

alias.url += ("/dokuwiki" => "/usr/share/dokuwiki")

$HTTP["url"] =~ "^/dokuwiki" {
  server.follow-symlink = "enable"
}

$HTTP["url"] =~ "/(\.|_)ht" {
  url.access-deny = ( "" )
}
$HTTP["url"] =~ "^/dokuwiki/(bin|data|inc|conf)" {
  url.access-deny = ( "" )
}
