nginx + passenger 配置

首先通过gem安装passenger

gem install passenger

因为Nginx不支持动态module载入，所以需要通过Passenger来自动下载，编译，安装由Passenger修改版的Nginx:

passenger-install-nginx-module

Yes: download, compile and install Nginx for me. (recommended)
The easiest way to get started. A stock Nginx 1.0.10 with Passenger
support, but with no other additional third party modules, will be
installed for you to a directory of your choice.

No: I want to customize my Nginx installation. (for advanced users)
Choose this if you want to compile Nginx with more third party modules
besides Passenger, or if you need to pass additional options to Nginx's
'configure' script. This installer will 1) ask you for the location of
the Nginx source code, 2) run the 'configure' script according to your
instructions, and 3) run 'make install'.

Whichever you choose, if you already have an existing Nginx configuration file,
then it will be preserved.

Enter your choice (1 or 2) or press Ctrl-C to abort: 这里建议选择1

因为它会自动下载ngnix。

Please specify a prefix directory [/opt/nginx]: /usr/local/nginx（自己设置路径，默认的路径是/opt/nginx）

Passenger会自动帮你将下面两行添加到Nginx的配置文件中/opt/nginx/conf/nginx.conf（很人性化）

http {
  ...
  passenger_root /Users/Daniel/.rvm/gems/ruby-1.9.2-p290/gems/passenger-3.0.10;
  passenger_ruby /Users/Daniel/.rvm/wrappers/ruby-1.9.2-p290/ruby;
  ...
}

请不要忘记将nginx命令行程序连接到/usr/sbin

sudo ln -s /ope/nginx/sbin/nginx /usr/sbin/
