3 | Catalyst::Manual::Deployment::FastCGI - Deploying Catalyst with FastCGI |
4 | |
5 | =head1 FastCGI Deployment |
6 | |
7 | FastCGI is a high-performance extension to CGI. It is suitable |
2d62c370 |
8 | for production environments, and is the standard method for deploying Catalyst |
9 | in shared hosting environments. |
1d2376f3 |
10 | |
11 | =head2 Pros |
12 | |
13 | =head3 Speed |
14 | |
15 | FastCGI performs equally as well as mod_perl. Don't let the 'CGI' fool you; |
16 | your app runs as multiple persistent processes ready to receive connections |
17 | from the web server. |
18 | |
19 | =head3 App Server |
20 | |
21 | When using external FastCGI servers, your application runs as a standalone |
22 | application server. It may be restarted independently from the web server. |
23 | This allows for a more robust environment and faster reload times when |
24 | pushing new app changes. The frontend server can even be configured to |
25 | display a friendly "down for maintenance" page while the application is |
26 | restarting. |
27 | |
28 | =head3 Load-balancing |
29 | |
30 | You can launch your application on multiple backend servers and allow the |
31 | frontend web server to load-balance between all of them. And of course, if |
32 | one goes down, your app continues to run fine. |
33 | |
34 | =head3 Multiple versions of the same app |
35 | |
36 | Each FastCGI application is a separate process, so you can run different |
37 | versions of the same app on a single server. |
38 | |
39 | =head3 Can run with threaded Apache |
40 | |
41 | Since your app is not running inside of Apache, the faster mpm_worker module |
42 | can be used without worrying about the thread safety of your application. |
43 | |
44 | =head2 Cons |
45 | |
46 | You may have to disable mod_deflate. If you experience page hangs with |
47 | mod_fastcgi then remove deflate.load and deflate.conf from mods-enabled/ |
48 | |
49 | =head3 More complex environment |
50 | |
51 | With FastCGI, there are more things to monitor and more processes running |
52 | than when using mod_perl. |
53 | |
54 | XXX - FIXME, note not just apache! |

56 | =head2 Standalone FastCGI Server |
1d2376f3 |
57 | |

58 | In server mode the application runs as a standalone server and accepts |
59 | connections from a web server. The application can be on the same machine as |
60 | the web server, on a remote machine, or even on multiple remote machines. |
61 | Advantages of this method include running the Catalyst application as a |
62 | different user than the web server, and the ability to set up a scalable |
63 | server farm. |
64 | |
65 | To start your application in server mode, install the FCGI::ProcManager |
66 | module and then use the included fastcgi.pl script. |
67 | |
68 | $ script/myapp_fastcgi.pl -l /tmp/myapp.socket -n 5 |
69 | |
70 | Command line options for fastcgi.pl include: |
71 | |
72 | -d -daemon Daemonize the server. |
73 | -p -pidfile Write a pidfile with the pid of the process manager. |
74 | -l -listen Listen on a socket path, hostname:port, or :port. |
75 | -n -nproc The number of processes started to handle requests. |
76 | |
77 | See below for the specific web server configurations for using the external |
78 | server. |

80 | =head1 WEB SERVERS |
81 | |
82 | Any web server which supports FastCGI should work with Catalyst. Configuration recipies for |
83 | well-known web servers are linked below, and we would welcome contributions from people |
84 | deploying Catalyst against other web servers. |
