Apache22 ruby on rails and mongrel

Süsteem toimib nii, et Apache suunab vhostide info mongrel serverile, mis siis railsi skripte esile manab.

Installime vajalikud päkitsad

cd /usr/ports/apache22
make install with_proxy_modules=yes
cd /usr/ports/lang/ruby18
make install && make clean
cd /usr/ports/devel/ruby-gems
make install && make clean
gem install mongrel
gem install rails
gem install mongrel-cluster


Loome vajalikud skriptid

pane rcrails /etc/init.d vms kausta ja start_mongrel iga railsi script kausta. start_mongreli sees määra USER ja GROUP, kellena see server jooksma peaks.

Meil on kaks eraldi railsis loodud programmi, mis asuvad

/home/rails/progeadmin/
/home/rails/veebiadmin/

/usr/local/etc/rails.conf või muusse faili (muuda vastavalt rcrails skripti) kirjuta näiteks:

RAILS_SERVERS="
/home/rails/progeadmin/
/home/rails/veebiadmin/



Mongrel Cluster Setup With mongrel working and our webapp directory prepared we can proceed with the mongrel_cluster configuration step:

$ sudo mongrel_rails cluster::configure -e production \
  -p 8000 -N 3 -c /var/www/apps/testapp -a 127.0.0.1 \
  --user mongrel --group mongrel

This will write a configuration file in config/mongrel_cluster.yml. We have setup to run our cluster in production mode as the user mongrel and will start 3 mongrel servers listening on ports 8000, 8001, and 8002. Now, lets do a quick test of what we have setup so far:

 $ sudo mongrel_rails cluster::start

Checking our host on ports 8000, 8001, and 8002 we should now be able to see our test application. We can stop all of those mongrels with sudo mongrel_rails cluster::stop.


cat home/progeadmin/rails/config/mongrel_cluster.yml --- user: programm cwd: /home/progeadmin/rails/ port: "8000" environment: production group: konkurss address: 127.0.0.1 pid_file: log/mongrel.pid servers: 3


httpd.conf

Kontrollime, et read oleksid

LoadModule proxy_module libexec/apache22/mod_proxy.so
LoadModule proxy_connect_module libexec/apache22/mod_proxy_connect.so
LoadModule proxy_ftp_module libexec/apache22/mod_proxy_ftp.so
LoadModule proxy_http_module libexec/apache22/mod_proxy_http.so
LoadModule proxy_ajp_module libexec/apache22/mod_proxy_ajp.so
LoadModule proxy_balancer_module libexec/apache22/mod_proxy_balancer.so

Nüüd loome mõlemale progele nende vhostid

<VirtualHost 193.40.0.10:80>

  DocumentRoot /home/rails/progeadmin/

  <Directory "/home/rails/progeadmin/">

    AllowOverride None
    Order allow,deny
    Allow from all

  RewriteEngine On

<VirtualHost 193.40.0.10:80>

 RewriteEngine On

 # Rewrite to trailing slash

 # test if this is /admin request
 RewriteCond %{REQUEST_URI} ^/admin(/.*)

 RewriteCond /home/rails/admin/public/%{ENV:AdminReq} -f
 # serve static files
 RewriteRule ^/admin/(.*) /home/rails/admin/public/$1 [L]
 # If request is not static, proxy to rails
 RewriteRule ^/(admin/.*)$ balancer://mongrel_cluster2/$1 [P,QSA,L]


</VirtualHost>

Ehitame proxyd

<Proxy balancer://mongrel_cluster2>
   BalancerMember http://127.0.0.1:8001
   BalancerMember http://127.0.0.1:8002
   BalancerMember http://127.0.0.1:8003

   BalancerMember http://127.0.0.1:8102
   BalancerMember http://127.0.0.1:8103

ja balaceri

Listen 8000

   SetHandler balancer-manager
   Deny from all
