Ruby, Rails, OSX and Linux fun

Requirements:

1. XCODE you can download xcode from http://developer.apple.com/tools/xcode/index.html

2. OSX 10.4, 10.5 or 10.6

Procedures:

1. Install Passenger

$ sudo gem install passenger

now check where is passenger installed:

$ passenger-config --root

in my case is: /opt/local/lib/ruby/gems/1.8/gems/passenger-2.2.5

2. Install nginx

If you have nginx from macports, deactivate it in case of conflicts.

You can activate anytime later

$ sudo port deactivate nginx

$ wget http://sysoev.ru/nginx/nginx-0.7.59.tar.gz

$ wget http://sysoev.ru/nginx/nginx-0.7.62.tar.gz

$ tar xpf nginx-0.7.62.tar.gz

$ cd nginx-0.7.62

I Recommend using nginx 0.6 series because I had a lot of “502 Bad Gateway” with 0.7 series.

$ wget http://sysoev.ru/nginx/nginx-0.6.37.tar.gz

$ tar xpf nginx-0.6.37.tar.gz

$ cd nginx-0.6.37

$ sudo ./configure --add-module=/opt/local/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/nginx/ \
  --with-http_ssl_module --user=nobody --group=nobody --with-http_gzip_static_module \
  --with-poll_module --prefix=/opt/local --with-pcre

Now edit your /etc/hosts and add the hosts for your local project

$ mate /etc/hosts

127.0.0.1   project1.local

127.0.0.1   project2.local

127.0.0.1   project3.local

3. Start nginx

sudo nginx

4. go to your browser and open project1.local

:)

5. Easy start/restart/stop

add this to your ~/.bash_profile file

Troubleshooting

1. Nginx is not running

- check the logs

- check if it is really not running:

$ ps aux | grep nginx

2. you see the nginx error “502 Bad Gateway”

- may there is a problem with the /var/folders/ permissions on OSX:

2009/06/13 16:14:33 [crit] 1106#0: *1 connect() to unix:/var/folders/xl/xlSRYvzFHH8Fcehc51ciyE+++TI/-Tmp-//passenger.1091/master/helper_server.sock failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: hassan.local, request: "GET / HTTP/1.1", upstream: "unix:/var/folders/xl/xlSRYvzFHH8Fcehc51ciyE+++TI/-Tmp-//passenger.1091/master/helper_server.sock:", host: "hassan.local"

to fix it I did this:

$ sudo find /var/folders/xl/ -name “master” -exec chmod 755 {} \;

$ sudo find /var/folders/xl/ -name “-Tmp-” -exec chmod 755 {} \;

everytime I reboot my mac I had to do that… I still dont know how to fix it…

anybody knows?

That is it for now.
