Mentioned things that would be useful but cann't be done in lighttpd scripts
#!rst ================== Configuration File ================== ------------ Module: core ------------ .. meta:: :keywords: lighttpd, configuration .. contents:: Table of Contents Description =========== Basic Syntax ------------ A BNF like notation: :: option : NAME = VALUE merge : NAME += VALUE NAME : modulename.key VALUE : ( <string> | <integer> | <boolean> | <array> | VALUE [ + VALUE ]*) <string> : "text" <integer>: digit* <boolean>: ( "enable" | "disable" ) <array> : "(" [ <string> "=>" ] <value> [, [ <string> "=>" ] <value> ]* ")" INCLUDE : "include" VALUE INCLUDE_SHELL : "include_shell" STRING_VALUE Example ------- :: # default document-root server.document-root = "/var/www/example.org/pages/" # TCP port server.port = 80 # selecting modules server.modules = ( "mod_access", "mod_rewrite" ) # variables, computed when config is read. var.mymodule = "foo" server.modules += ( "mod_" + var.mymodule ) # var.PID is initialised to the pid of lighttpd before config is parsed # include, relative to dirname of main config file include "mime.types.conf" # read configuration from output of a command include_shell "/usr/local/bin/confmimetype /etc/mime.types" Conditional Configuration ========================= Most options can be configured conditionally by using the following syntax (including nesting). :: <field> <operator> <value> { ... <field> <operator> <value> { ... nesting: match only when parent match } } else <field> <operator> <value> { ... the "else if" block } where <field> is one of one of the following: $HTTP["cookie"] match on cookie $HTTP["host"] match on host $HTTP["useragent"] match on useragent $HTTP["referer"] match on referer $HTTP["url"] match on url. If there are nested blocks, this must be the most inner block. $HTTP["querystring"] match on querystring, eg, after the ? in this type url: index.php?module=images.. $HTTP["remoteip"] match on the remote IP or a remote Network (Warning: doesn't work with IPv6 enabled) $HTTP["scheme"] (Introduced in version 1.4.19) match on the scheme used by the incoming connection. This is either "http" or "https". $SERVER["socket"] match on socket. Value must be on the format "ip:port" where ip is an IP address and port a port number, or ":port" to match port only. Only equal match (==) is supported. It also binds the daemon to this socket. Use this if you want to do IP/port-based virtual hosts. $PHYSICAL["path"] (Introduced in version 1.5.0) match on the mapped physical path of the file / cgi script to be served. $PHYSICAL["existing-path"] (Introduced in version 1.5.0) match on the mapped physical path of the file / cgi script to be served only if such a file exists on the local filesystem. <operator> is one of: == string equal match != string not equal match =~ perl style regular expression match !~ perl style regular expression not match and <value> is either a quoted ("") literal string or regular expression. Example ------- :: # disable directory-listings for /download/* dir-listing.activate = "enable" $HTTP["url"] =~ "^/download/" { dir-listing.activate = "disable" } # handle virtual hosting # map all domains of a top-level-domain to a single document-root $HTTP["host"] =~ "(^|\.)example\.org$" { server.document-root = "/var/www/htdocs/example.org/pages/" } # multiple sockets $SERVER["socket"] == "127.0.0.1:81" { server.document-root = "..." } $SERVER["socket"] == "127.0.0.1:443" { ssl.pemfile = "/var/www/certs/localhost.pem" ssl.engine = "enable" server.document-root = "/var/www/htdocs/secure.example.org/pages/" } # deny access for all googlebot $HTTP["useragent"] =~ "Google" { url.access-deny = ( "" ) } # deny access for all image stealers (anti-hotlinking for images) $HTTP["referer"] !~ "^($|http://www\.example\.org)" { url.access-deny = ( ".jpg", ".jpeg", ".png" ) } # deny the access to www.example.org to all user which # are not in the 10.0.0.0/8 network $HTTP["host"] == "www.example.org" { $HTTP["remoteip"] != "10.0.0.0/8" { url.access-deny = ( "" ) } } # Allow only 200.19.1.5 and 210.45.2.7 to # have access to www.example.org/admin/ $HTTP["host"] == "www.example.org" { #!~ is a perl style regular expression not match $HTTP["remoteip"] !~ "^(200\.19\.1\.5|210\.45\.2\.7)$" { $HTTP["url"] =~ "^/admin/" { url.access-deny = ( "" ) } } } Troubleshooting --------------- If you're not running on the default port, $HTTP["host"] will have the port appended to it, so regular expressions ending in "$" (without allowing for a port) won't match. To match with or without a port, change "(^|\\.)example\\.org$" to "(^|\\.)example\\.org(\\:[0-9]*)?$" advanced usage ============== check the blog: http://blog.lighttpd.net/articles/2005/05/07/advanced-configuration-in-up-upcoming-1-4-x Using variables =============== You can set your own variables in the configuration to simplify your config. :: var.basedir = "/home/www/servers/" $HTTP["host"] == "www.example.org" { server.name = "www.example.org" include "incl-base.conf" } in incl-base.conf: server.document-root = basedir + server.name + "/pages/" accesslog.filename = basedir + server.name + "/logs/access.log" You can also use environment variables or the default variables var.PID and var.CWD: :: var.basedir = env.LIGHTTPDBASE $HTTP["host"] == "www.example.org" { server.name = "www.example.org" include "incl-base.conf" include "incl-fastcgi.conf" } in incl-fastcgi.conf: fastcgi.server = ( ... => (( "socket" => basedir + server.name + "/tmp/fastcgi-" + PID + ".sock" )) ) Or like the lighttpd script for rails does: :: var.basedir = var.CWD server.document-root = basedir + "/public/" Some useful things that can NOT be done in lighttpd config (you need to create a script in a real programming language and than use include_shell): :: # testing if a variable has been set is NOT possible var.not_sure_if_it_exists == undefined { ... set to default value ... } # removing from arrays is NOT possible server.modules -= ( "mod_idontwantyou" ) Global context ============== :: global { ... } You don't need it in the main configuration file. But you might have difficulty setting a server wide configuration inside a included-file from conditionals. Example ------- :: in lighttpd.conf: server.modules = () $HTTP["host"] == "www.example.org" { include "incl-php.conf" } in incl-php.conf: global { server.modules += ("mod_fastcgi") static-file.exclude-extensions += (".php") } fastcgi.server = "..."
