# Test (rails app만들고, mongrel 서버 시작하기)

$ mkdir ~/rals;  cd ~/rails;

$ rails www  (www rails app만들기)

$ mongrel_rails cluster::configure-p 8001 -a 127.0.0.1 -N 3

$ mongrel_rails cluster::start

 

>> http://127.0.0.1:8001 로 접속시, Rails "welcome" 화면을 볼수 있을 것이다.

 

# Apache 2.2

1. 다음 모듈들 필요

  $ a2enmod rewirte

  $ a2enmod proxy

  $ a2enmod proxy_balancer

  > Apache 재시작

 

2. apache2.conf 에 httpd.conf 추가
  "Include /home/xxx/conf/httpd.conf"

3. 위 httpd.conf에는 다음 내용 추가

NameVirtualHost *:80 <VirtualHost *:80> ServerName xxx-server.org Include /home/xxx/conf/www.conf </VirtualHost> <VirtualHost *:80> ServerName www.xxx-server.org Include /home/xxx/conf/www.conf </VirtualHost>

4. 다음은, 다른 Config 파일 link-out 시키는 법

DocumentRoot /home/rcrowley/rails/www/public RewriteEngine On RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://www_mongrel%{REQUEST_URI} [P,QSA,L] <Proxy balancer://www_mongrel> BalancerMember http://127.0.0.1:8001 BalancerMember http://127.0.0.1:8002 BalancerMember http://127.0.0.1:8003 </Proxy>

5. "/etc/init.d/mongre" 을 다음처럼 수정하면 편함

#! /bin/sh do_start() { echo "Starting Mongrel..." mongrel_rails cluster::start -C ~rcrowley/rails/www/config/mongrel_cluster.yml } do_stop() { echo "Stopping Mongrel..." mongrel_rails cluster::stop -C ~rcrowley/rails/www/config/mongrel_cluster.yml } case "$1" in start) do_start ;; stop) do_stop ;; restart|force-reload) do_stop do_start ;; *) echo "Usage: $SCRIPTNAME {start|stop|restart}" >&2 exit 3 ;; esac

5. Mongre 시작

  $ update-rc.d mongrel defaults

6. Mongrel - Cluster 로 시작

   1) 방법 1

        각 rails application 디렉토리 이동 후,

         $ mongrel_rails start -e development -d -p 8080 //8080포트로 시작

         $ mongrel_rails start -e development -d -p 8090 //8090포트로 시작

   2) 방법 2

         $ mongrel_rails cluster::configure -e development -p 8080 -N 3 -c /<rails_app_path>

         $ mongrel_rails cluster::configure -e development -p 8090 -N 3 -c /<rails_app_path>
