You can set up multiple domains by using ngnix and mongrel (or) apache and mongrel.
This is how I do it:
1. Set up mongrel for each domain to listen on a different set of ports. For instance, on domain1, I have mongrel listening on 8000, 8001 and 8002. On domain 2, I have mongrel listening on 9000, 9001 and 9002
2. Set up ngnix (or apache) to listen on port 80 and have it forward the requests for each domain up to the appropriate set of mongrels.
3. Profit.
As to why I set mongrels to listen on 8000...8002 and 9000...9002, that's because I also have them set with production environment on those ports (so no debug error messages are sent to the user). If I have an error suddenly occurring, I start up another instance on port 3000 with debugging on and check what the message is
.
For your benefit, I'm adding my mongrel_cluster.yml and nginx.conf files.
mongrel_cluster.yml for domain1.com
Code:
user: wwwuser
cwd: /home/wwwuser/rails/domain1
log_file: log/mongrel.log
port: "8000"
environment: production
group: wwwuser
address: 127.0.0.1
pid_file: tmp/pids/mongrel.pid
servers: 3
mongrel_cluster.yml for domain2.com
Code:
user: wwwuser
cwd: /home/wwwuser/rails/domain2
log_file: log/mongrel.log
port: "9000"
environment: production
group: wwwuser
address: 127.0.0.1
pid_file: tmp/pids/mongrel.pid
servers: 3
Note that for domain1.com, I also own domain1.net and domain1.org and I have two separate rules to redirect domain1.net and domain1.org back to domain1.com in my nginx.conf file.
nginx.conf file
Code:
user wwwuser wwwuser;
worker_processes 6;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
