Hi all,
I am out of my head here...
I have a 3 node cluster with 10 mongrels running on each. When I deploy, I break all the mongrels every time. I have tried just about everything. I can restart my mongrels without a hitch manually, it's only when I use cap deploy. Maybe I am missing something here... so if I can get some help it would be appreciated. The errors are the typical mongrel pid errors, I can paste them if need be.
I have mongrel_cluster.yml sym linked from /{current_path}/config/mongrel_cluster.yml to /etc/mongrel_cluster/mongrel_cluster.yml
cwd: /home/app/current port: "8000" address: 127.0.0.1 pid_file: log/mongrel.pid environment: production servers: 10
here is a snippet of my deploy.rb
<snip>
require 'mongrel_cluster/recipes' require 'capistrano'
# below snipped for brevity role :web role :app
...
# restart mongrel with /etc/init.d/mongrel_cluster restart desc "Restart the web server" task :restart, :roles => :app do begin run "sudo /etc/init.d/mongrel_cluster stop" run "sleep 5" run "sudo /etc/init.d/mongrel_cluster start" end
... # couple of tasks to chown some files and directories desc "Only app servers get this applied to them post-deployment" task :after_app_deploy, :roles=>:app do sudo "chown -PRf foo:foo #{deploy_to}/current/" sudo "chown -PRf foo:foo #{deploy_to}/releases/" sudo "chmod -Rf 755 #{deploy_to}/releases/" sudo "chmod -Rf 750 #{deploy_to}/current/public/" end
desc "Apache restarter" task :kick_apache, :roles=>:web do sudo "/usr/local/apache/bin/apachectl restart" end
Now, mongrel gets restarted even if I don't use the above when I restart when I run deploy.. but I don't see where I can change that or if that is in fact causing the problem.
for whatever reason, mongrels never start on 8000 - 8004, but do start from 8005 - 8009, so I am thinking something in the cap script. I did migrate recently from lighty+fastcgi to apache+mongrel and I have 10 mongrels per machine on ports 8000 - 8009. I was thinking that dispatch was screwing up ports 8000-04 somehow.. ( totally guessing )
I was thinking about writing a task similar to below... but I think it is overkill.
desc "Kill all the pids in case there are some zombies and remove the .pid files" task :before_before_deploy, roles => :app do begin run "sudo kill -9 `ps -ef | grep mongrel | egrep -v grep | awk '{print $2}'`" run "cd /home/user/app/log && sudo rm -rf *.pid" end
task :after_after_deploy, roles => :app do begin " sudo /etc/init.d/mongrel_cluster start" end
</snip>
Hopefully someone can see something that I don't. Thanks for your time
