unicornのインストールと設定

インストールは gem コマンド一発。

[root@www2465uo Lathercraft]# gem install unicorn

設定ファイルを ${RAILS_ROOT}/config の中に作る。

worker_processes 2
working_directory "/var/www/Lathercraft"

listen "/var/run/unicorn/unicorn_lathercraft.sock"
pid "/var/run/unicorn/unicorn_lathercraft.pid"

preload_app true

他にもいろいろ書けるみたいだけど、これで最低限のよう。sock や pid のためのディレクトリを作る。

[root@www2465uo Lathercraft]# mkdir /var/run/unicorn
[root@www2465uo Lathercraft]# chmod 777 /var/run/unicorn

ファイル自体は勝手に作ってくれるらしい。

unicornの起動

[root@www2465uo Lathercraft]# unicorn_rails -c /var/www/Lathercraft/config/unicorn.rb -E production -D

Nginxの設定

/etc/nginx/conf.d/www.lathercraft.new.conf を次のようにした。

upstream unicorn-lathercraft {
    server unix:/var/run/unicorn/unicorn_lathercraft.sock;
}

server {
    # port
    listen 80;

    # server name
    server_name www.lathercraft.net;

    # document root
    root /var/www/Lathercraft;

    # index
    #index index.php index.html index.htm;

    # log files
    access_log /var/log/nginx/www.lathercraft.net/access.log main;
    error_log /var/log/nginx/www.lathercraft.net/error.log warn;

    location / {
        root /var/www/Lathercraft;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_pass http://unicorn-lathercraft;
    }

}

これで Nginx を再起動。

[root@www2465uo www]# service nginx restart
nginx を停止中:                                            [  OK  ]
nginx を起動中:                                            [  OK  ]

ブラウザからアクセスすると、アプリのホームページが表示された！

unicornの自動起動

さいごに、OS を起動した時に unicorn も自動起動するようにしておく。/etc/init.d/unicorn_lathercraft を次のようにした。

#!/bin/bash
#
# unicorn_lathercraft Startup script for unicorn.
#
# chkconfig: - 85 15
