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.

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

  DocumentRoot /home/rails/progeadmin/

  RewriteEngine On


 # Redirect all non-static requests to cluster
 #RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
 RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L]

</VirtualHost>

<VirtualHost 193.40.0.10:80>
 ServerName veebiadmin
 DocumentRoot /home/rails/veebiadmin/

 <Directory "/home/rails/veebiadmin/">
   Options FollowSymLinks
   AllowOverride None
   Order allow,deny
   Allow from all
 </Directory>


 RewriteEngine On

 # Rewrite to trailing slash
 RewriteRule ^/admin$ /admin/ [R,L]

 # test if this is /admin request
 RewriteCond %{REQUEST_URI} ^/admin(/.*)
 # strip off /admin and put result in ENV
 RewriteRule ^/admin(.*) /admin$1 [E=AdminReq:$1]

 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
