How to set up a Rails application with Mongrel and Apache
ApacheでMongrelのセットアップ
１）mongrel_cluster.ymlをダウンロードし、hostname特有のPIDを書き込みます。
# cd /home/YOUR/PATH/TO/RAILS/APP
# svn export http://svn.joyent.com/public/accelerators/configs/mongrel/mongrel_cluster.yml config/mongrel_cluster.yml
２）mongrel clusterを起動。
# cd /home/YOUR/PATH/TO/RAILS/APP
# mongrel_rails cluster::start
３）チェック。
# curl `myprivateip`:8000
# curl -I `myprivateip`:8000
200OKとなっていればOK
HTTP/1.1 200 OK
Connection: close
Date: Tue, 06 Mar 2007 07:09:13 GMT
Status: 200 OK
Server: Mongrel 1.0.1
Content-Type: text/html
Content-Length: 0
なっていなければ、production.logをチェック。
４）mongrelのプロキシバランサにあわせてapacheのバーチャルホストを設定
# cd /opt/csw/apache2/etc/virtualhost
# nano myrailsapp-domain.conf
中身はこんな感じ
<VirtualHost YOUR-PUBLIC-IP:80>
ServerName YOURDOMAIN.com >ServerAlias *.YOURDOMAIN.com
DocumentRoot /home/YOUR/PATH/TO/RAILS/APP/public
<Directory "/home/YOUR/PATH/TO/RAILS/APP/public/">
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ balancer://app1-mongrels%{REQUEST_URI} [P,QSA,L]
<Proxy balancer://app1-mongrels>
BalancerMember http://YOUR-PRIVATE-IP:8000
BalancerMember http://YOUR-PRIVATE-IP:8001
BalancerMember http://YOUR-PRIVATE-IP:8002
BalancerMember http://YOUR-PRIVATE-IP:8003
</Proxy>
ProxyPass /images !
ProxyPass /stylesheets !
ProxyPass / balancer://app1-mongrels
ProxyPassReverse / balancer://app1-mongrels
ProxyPreserveHost On
</VirtualHost>
- ProxyPass /images ! と ProxyPass /stylesheets !を記述しないとサーバがうまく動かないらしい。
- “balancer://app1-mongrels”にはユニークな名前を。
- ポートはmongrel_cluster.ymlと同じにする。
apacheを再起動
apachectl restart
指定したポートで動作しなければ、再度設定を繰り返す事。
５）最後に、リブートの準備を行う。
# nano /HOME/YOUR/PATH/TO/RAILS/APP/mongrel-app-smf.xml
