Nginx, Passenger, Rack, Sinatraで起動してみる

Passengerがnginxで使えるみたい。

nginxモジュールをインストールする際にnginxをダウンロードするかどうか聞かれました。
ソースからnginxをインストールしているなら、そのディレクトリを指定すればよいらしいけど、ちょっと前にnginxをyumからに変えていたので一旦削除。

sudo gem install passenger
passenger-install-nginx-module

Automatically download and install Nginx?

Nginx doesn't support loadable modules such as some other web servers do,
so in order to install Nginx with Passenger support, it must be recompiled.

Do you want this installer to download, compile and install Nginx for you?

 1. Yes: download, compile and install Nginx for me. (recommended)
    The easiest way to get started. A stock Nginx 0.6.37 with Passenger
    support, but with no other additional third party modules, will be
    installed for you to a directory of your choice.

 2. 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: 1

ほとんどreturnキー押して終了。

/opt/nginx以下にファイルができます。

conf/nginx.confに以下が記述されてます。

http {
    ...
    passenger_root /usr/local/ruby/lib/ruby/gems/1.8/gems/passenger-2.2.4;
    passenger_ruby /usr/local/ruby/bin/ruby;
    ...
}

あとはvirtual.confとか作って、

server {
   listen 80;
   server_name www.yourhost.com;
   root /somewhere/public;   # <--- be sure to point to 'public'!
   passenger_enabled on;
}
&#91;/sourcecode&#93;

こんな風に書けばいいようで。

passengerのモジュールインストール中に説明してくれるので親切。

で、今回はSinatraを使っているのでSinatraアプリ以下にconfig.ruをつくり、publicとtmpディレクトリを用意。

起動ファイルはyumでインストールした時のものを流用します。

起動したり終了したりが楽。

/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart

わぁー

やっぱメモリは喰うのね。。
