20 | =head2 $self->run($c, $listen, { option => value, ... }) |

21 | |
22 | Starts the FastCGI server. If C<$listen> is set, then it specifies a |
23 | location to listen for FastCGI requests; |
24 | |
25 | Form Meaning |
26 | /path listen via Unix sockets on /path |
27 | :port listen via TCP on port on all interfaces |
28 | hostname:port listen via TCP on port bound to hostname |
29 | |
30 | Options may also be specified; |
31 | |
32 | Option Meaning |
33 | leave_umask Set to 1 to disable setting umask to 0 |
34 | for socket open |
35 | nointr Do not allow the listener to be |
36 | interrupted by Ctrl+C |
37 | nproc Specify a number of processes for |
38 | FCGI::ProcManager |
dc2fc680 |
39 | pidfile Specify a filename for the pid file |
526b698a |
40 | manager Specify a FCGI::ProcManager sub-class |
41 | detach Detach from console |

141 | disassociates from the terminal. |
142 | |
143 | However, this does B<not> change the current working directory to "/", |
144 | as normal daemons do. It also does not close all open file |
145 | descriptors (except STDIN, STDOUT and STDERR, which are re-opened from |

162 | =head1 WEB SERVER CONFIGURATIONS |
163 | |
164 | =head2 Apache 1.x, 2.x |
165 | |
166 | Apache requires the mod_fastcgi module. The following config will let Apache |
167 | control the running of your FastCGI processes. |
168 | |
169 | # Launch the FastCGI processes |
170 | FastCgiIpcDir /tmp |
8f753f10 |
171 | FastCgiServer /var/www/MyApp/script/myapp_fastcgi.pl -idle-timeout 300 -processes 5 |
198b0efa |
172 | |
173 | <VirtualHost *> |
174 | ScriptAlias / /var/www/MyApp/script/myapp_fastcgi.pl/ |
175 | </VirtualHost> |
176 | |
177 | You can also tell Apache to connect to an external FastCGI server: |
178 | |
179 | # Start the external server (requires FCGI::ProcManager) |
180 | $ script/myapp_fastcgi.pl -l /tmp/myapp.socket -n 5 |
181 | |
182 | # Note that the path used in FastCgiExternalServer can be any path |
183 | FastCgiIpcDir /tmp |
184 | FastCgiExternalServer /tmp/myapp_fastcgi.pl -socket /tmp/myapp.socket |
185 | |
186 | <VirtualHost *> |
187 | ScriptAlias / /tmp/myapp_fastcgi.pl/ |
188 | </VirtualHost> |
189 | |
190 | For more information on using FastCGI under Apache, visit |
191 | L<http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html> |
192 | |
193 | =head2 Lighttpd |
194 | |
195 | This configuration was tested with Lighttpd 1.4.7. |
196 | |
197 | server.document-root = "/var/www/MyApp/root" |
198 | |
199 | fastcgi.server = ( |
200 | "" => ( |
201 | "MyApp" => ( |
202 | "socket" => "/tmp/myapp.socket", |
203 | "check-local" => "disable", |
204 | "bin-path" => "/var/www/MyApp/script/myapp_fastcgi.pl", |
205 | "min-procs" => 2, |
206 | "max-procs" => 5, |
207 | "idle-timeout" => 20 |
208 | ) |
209 | ) |
210 | ) |
211 | |
25810c41 |
212 | You can also run your application at any non-root location. |
213 | |
214 | fastcgi.server = ( |
215 | "/myapp" => ( |
216 | "MyApp" => ( |
217 | # same as above |
218 | ) |
219 | ) |
220 | ) |
221 | |
222 | You can also use an external server: |
198b0efa |
223 | |
224 | # Start the external server (requires FCGI::ProcManager) |
225 | $ script/myapp_fastcgi.pl -l /tmp/myapp.socket -n 5 |
226 | |
227 | server.document-root = "/var/www/MyApp/root" |
228 | |
229 | fastcgi.server = ( |
230 | "" => ( |
231 | "MyApp" => ( |
232 | "socket" => "/tmp/myapp.socket", |
233 | "check-local" => "disable" |
234 | ) |
235 | ) |
236 | ) |
237 | |

239 | L<http://www.lighttpd.net/documentation/fastcgi.html> |
240 | |
241 | =head2 IIS |
242 | |
243 | It is possible to run Catalyst under IIS with FastCGI, but we do not |
244 | yet have detailed instructions. |
