= Migrating from Apache to lighty =
== Basic Options ==
{{{
Options +FollowSymLinks
}}}
becomes
{{{
server.follow-symlinks = "enable"
}}}
== Accesslog ==
Accesslogs are written by mod_accesslog and support the same options in
{{{
accesslog.format = ...
}}}
as Apache.
If you need logfile rotation use one of two way:
* [http://iain.cx/src/logrotate/ logrotate] as it is used in debian package
* [http://www.cronolog.org/ cronolog]
=== logrotate ===
If you don't use the debian package copy ./debian/lighttpd.logrotate to /etc/logrotate.d/
logrotate will send lighttpd a SIGHUP when it is time to rotate the logs and lighttpd reopen the logs accordingly.
=== cronolog ===
With cronolog you pipe the accesslog to a pipe and let a external program handle the logfile writing:
{{{
accesslog.filename = "|/usr/sbin/cronolog /web/logs/%Y/%m/%d/access.log"
}}}
== mod_rewrite ==
[http://www.lighttpd.net/documentation/rewrite.html mod_rewrite] is more trickier as the idea how it is handled is completly different.
First of all we always match on the full relative request-uri that is submitted by the user. That means that we are always using the [QSA] (query string append) flag from [http://httpd.apache.org/docs/mod/mod_rewrite.html mod_rewrite in Apache].
This is example is based on a problem from http://dir.onlinesearch.ws/ sent in by dbird@freenode.
{{{
RewriteEngine On
RewriteBase /instadir/
RewriteCond %{REQUEST_FILENAME} -d
# Fix trailing slash problem
RewriteRule ^(.+[^/])$ $1/ [R,L]
# Do not try to treat the following resources as parameters to index.php
RewriteRule ^index.php.*$ - [L]
RewriteRule ^dmoz.css$ - [L]
RewriteRule ^admin[/]?.*$ - [L]
RewriteRule ^img[/]?.*$ - [L]
RewriteRule ^[/]{0,}(.*)$ index.php?area=browse&cat=$1 [QSA,L]
}}}
These rewrites want to rewrite everything that is not the index.php, dmoz.css, admin-interface or something from the image-directory to a parameter of the index.php page. The base directory for this match is ''/instadir/''.
{{{
## for all URLs in /instadir/ that are not index.php, dmoz.css, admin or img, do ...
$HTTP["url"] =~ "^/instadir/(?!index.php|dmoz.css|admin|img)" {
## don't get afraid by the pattern, it matches the request-string
## and the optional query-string
url.rewrite = ( "^/instadir/([^?]*)(?:\?(.*))?" =>
"/instadir/index.php?area=browse&cat=$1&$2" )
}
}}}
The conditional is using regex-magic called [http://perlpod.com/5.9.1/pod/perlre.html#Extended%20Patterns zero-width negative look-ahead assertion] and is something from the advanced chapters of your [http://www.oreilly.com/catalog/regex/ regex book].
== mod_fastcgi ==
If you have 2 extensions assigned to on fastcgi handler in Apache like
{{{
AddType fastcgi-php .php .phtml
}}}
you need two entries in the fastcgi.server config:
{{{
fastcgi.server = ( ".php" => (( "bin-path" => "/my/fastcgi-php",
"socket" => "/path/to/php.socket" )), ))
".phtml" => (( "socket => "/path/to/php.socket ))
)
}}}
The first entry will create the php-fcgi process and the second will reuse the same socket.
