RT 4.2.12 Documentation
Web deployment
Setting up the web interface
As of RT 3.9, RT's web interface speaks PSGI (http://plackperl.org) which lets you use RT with any PSGI-supported web server (which includes Apache, nginx, lighttpd, etc).
Standalone
The standalone RT web server is backed by a pure-Perl server engine (HTTP::Server::PSGI). This standalone server is appropriate for development and testing, but is not appropriate for production use.
You should not run this server against port 80 (which is the default port) because that requires root-level privileges and may conflict with any existing listeners. So choose a high port (for example 8080) and start the standalone server with:
/opt/rt4/sbin/rt-server --port 8080You can also run rt-server with any other PSGI server, for example, to use Starman, a high performance preforking server:
/opt/rt4/sbin/rt-server --server Starman --port 8080Apache
WARNING: Both mod_speling and mod_cache are known to break RT. mod_speling will cause RT's CSS and JS to not be loaded, making RT appear unstyled. mod_cache will cache cookies, making users be spontaneously logged in as other users in the system.
See also "Apache configuration" in authentication, in case you intend to use Apache to provide authentication.

WARNING: Before mod_fcgid 2.3.6, the maximum request size was 1GB. Starting in 2.3.6, this is now 128Kb. This is unlikely to be large enough for any RT install that handles attachments. You can read more about FcgidMaxRequestLen at http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html#fcgidmaxrequestlen
Most distributions will have a mod_fcgid.conf or similar file with mod_fcgid configurations and you should add:
FcgidMaxRequestLen 1073741824to return to the old default.

</VirtualHost>mod_perl 2.xx
WARNING: mod_perl 1.99_xx is not supported.
WARNING: Due to thread-safety limitations, all timestamps will be presented in the webserver's default time zone when using the worker and event MPMs; the $Timezone setting and the user's timezone preference are ignored. We suggest the prefork MPM or FastCGI deployment if your privileged users are in a different timezone than the one the server is configured for.
NOTE: RT 3.8 and below suggested use of SetHandler perl-script; this is incorrect for RT 4, and (starting in RT 4.0.11) RT will refuse to start, to prevent difficulties sending mail from RT. Change to SetHandler modperl, as the example below uses.

nginx
nginx requires that you start RT's fastcgi process externally, for example using spawn-fcgi:
spawn-fcgi -u www-data -g www-data -a 127.0.0.1 -p 9000 \
-- /opt/rt4/sbin/rt-server.fcgiWith the nginx configuration:
server {
listen 80;
server_name rt.example.com;
access_log /var/log/nginx/access.log;
location / {
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME "";
fastcgi_param PATH_INFO $uri;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_pass 127.0.0.1:9000;
}
}lighttpd
server.modules += ( "mod_fastcgi" )
$HTTP["host"] =~ "^rt.example.com" {
fastcgi.server = (
"/" => (
"rt" => (
"socket" => "/opt/rt4/var/socket",
"bin-path" => "/opt/rt4/sbin/rt-server.fcgi",
"check-local" => "disable",
"fix-root-scriptname" => "enable",
)
)
)
}Running RT at /rt rather than /
First you need to tell RT where it's located by setting $WebPath in your RT_SiteConfig.pm:
# Important: don't include a trailing slash here. Read `perldoc
# etc/RT_Config.pm` for more information.
Set($WebPath, "/rt");Then you need to update your Apache configuration to match. Prefix any RT related ScriptAlias and Location directives with /rt. You should also make sure DocumentRoot is not set to /opt/rt4/share/html/, otherwise RT's source will be served from /.
For example: if you're using the sample FastCGI config above, you might change the relevant directives to:
ScriptAlias /rt /opt/rt4/sbin/rt-server.fcgi/
# Set DocumentRoot as appropriate for the other content you want to serve
DocumentRoot /var/www
<Location /rt>
...
</Location>If you're using the sample mod_perl configuration, you only need to change the Location directive.
If you're not using Apache, please see Plack::Handler::FCGI or the web server's own documentation for configuration examples.
