A little while ago, I mentioned the web server Nginx, and had planned to do some fooling with it to see how it handled proxying for a mongrel cluster. I had a spare 20 minutes today, and in the time frame I was able to install Nginx, put together a config file, install mongrel and the cluster controller, and put together a simple Rails app for testing. After realizing I had a typo in my config file, it was up and running like a dream. My config files:
mongrel_cluster.yml
1 user: mongrel
2 cwd: /home/pratzsch/apps/demo
3 log_file: log/mongrel.log
4 port: "5001"
5 environment: development
6 group: mongrel
7 address: 127.0.0.1
8 pid_file: /etc/mongrel.pid
9 servers: 3

12 include /etc/nginx/mime.types;
13 default_type application/octet-stream;
14 access_log /var/log/nginx/access.log

16 sendfile on;
17 tcp_nopush on;

22 upstream mongrel {
23 server 127.0.0.1:5001;
24 server 127.0.0.1:5002;
25 server 127.0.0.1:5003;
26 }
27
28 gzip on;
29 gzip_min_length 1100;
30 gzip_buffers 4 8k;
31 gzip_types text/plain;

35 server_name localhost;
36 root /etc/public;
37
38 access_log off;
39 rewrite_log on;

41 location ~ ^/$ {
42 if (-f /index.html){
43 rewrite (.*) /index.html last;
44 }
45
46 proxy_pass http://mongrel;
47 }
48
49 location / {
50 if (!-f $request_filename.html) {
51 proxy_pass http://mongrel;
52 }
53
54 rewrite (.*) $1.html last;
55 }
56
57 location ~ .html {
58 root /etc/public;
59 }
60
61 location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xl s|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mov)$ {

63 }
64
65 location / {
66 proxy_pass http://mongrel;
67 proxy_redirect off;
68 proxy_set_header Host $host;
69 proxy_set_header X-Real-IP $remote_addr;
70 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
71 }
72
73 }
74 }
That's all there is to it. The mongrel_cluster_ctl command can seem to be a little tempermental, but one adjusts to it quickly.
This stack in my view beats the pants off of the Apache2.2 solution.
