I use capistrano 3, rvm und bundler for my deployment.
The thin server are restarted like this:
within release_path do
execute :bundle, :exec, "thin restart -O -C config/thin/staging.yml"
end
This work fine and generate this command:
cd /var/www/foo/releases/20140320154611 && ~/.rvm/bin/rvm ruby-2.0.0-p353#foo do bundle exec thin restart -O -C config/thin/staging.yml
Now I need to restart the thin's with this setting RUBY_GC_MALLOC_LIMIT=90000000 and I dont know how to set this up in the execute command?
The script has to setup rvm for knowing bundle, and RUBY_GC_MALLOC_LIMIT for thin
Not working:
Because rvm is not set (execute :bundle # set a rvm hook)
execute "RUBY_GC_MALLOC_LIMIT=90000000", :bundle, :exec, "thin restart -O -C config/thin/staging.yml"
2.same here
execute "RUBY_GC_MALLOC_LIMIT=90000000 bundle exec thin restart -O -C config/thin/staging.yml"
I have found a solution....
execute :bundle, :exec, "'RUBY_GC_MALLOC_LIMIT=90000000 thin restart -O -C config/thin/staging.yml'"

I have a Procfile setup that is running a number of processes successfully:
# /Procfile
redis: bundle exec redis-server
sidekiq: bundle exec sidekiq -v -C ./config.yml
forward: forward 4567 mock-api
I need to add one more process - a Sinatra app that lives in a different directory on my machine. If I cd to the directory, I can start it from the Terminal with:
$ rackup -p 4567
And I can start it from a different directory using the Terminal with:
$ sh -c 'cd /Path/to/project/ && exec rackup -p 4567'
But how should I do this using foreman. I have tried adding the following, but it fails silently:
mock-api: sh -c 'cd /Path/to/project/ && exec rackup -p 4567'
Is this even possible? And if so, how?
Of all the stupid things ...
It was failing because of the hyphen in the process name.
What is the best way to launch ruby script under another user via su command and from another script?
I have a bash script with the following command for launching unicorn:
sudo -u unicornuser sh -l -c "bundle exec unicorn_rails -E production -D"
This script is an init.d script and it being execute when system starts and manually also.
The problem is the default ruby on system is 1.8, other rubyes (1.9) is working under RVM. I need to modify above script that it can execute ruby with RVM (non system wide)
Now I've migrated for this notation:
su -l -c "rvm use ruby-1.9.3-p125 && bundle exec unicorn_rails -E production -D" unicornuser
this worked for me, but I guess there must be a better way to do this.
You should use wrappers:
rvm wrapper ruby-1.9.3-p125 ext_1.9.3 bundle
This will create $rvm_path/bin/ext_1.9.3_bundle, so now you can use:
/full/path/to/rvm/bin/ext_1.9.3_bundle exec unicorn_rails -E production -D
replace /full/path/to/rvm with output from echo $rvm_path
I'm trying to start unicorn_rails in a ruby script, and after executing many commands in the script, when the script gets to the following line
%x[bash -ic "bash <(. ~/.bashrc); cd /home/www-data/rails_app; bundle exec unicorn_rails -p 8000 -E production -c /home/www-data/rails_app/config/unicorn.rb -D"]
the script stops, generating the following output
[1]+ Stopped ./setup_rails.rb
and returns to the Linux prompt. If I type "fg", the script finishes running, the line where the script had stopped gets executed and unicorn gets started as a daemon.
If I run the line in a separate script, the script completes without stopping.
UPDATE_1 -
I source .bashrc because earlier in the script I install rvm and to get it to run with the correct environment I have the following:
%x[echo "[[ -s \"$HOME/.rvm/scripts/rvm\" ]] && source \"$HOME/.rvm/scripts/rvm\"" >> .bashrc]
%x[bash -ic "bash <(. ~/.bashrc); rvm install ruby-1.9.2-p290; rvm 1.9.2-p290 --default;"]
So if I want to run correct version of rvm, ruby and bundle I need to source .bashrc
end UPDATE_1
Does anyone have any idea what could cause a ruby script to halt as if control-Z was pressed?
Not sure why it's stopping, but my general rule of thumb is to never source my .bashrc in a script -- that might be the source of your problem right there, but I can't be sure without seeing what's in it. You should be able to change your script to something like:
$ vi setup_rails.sh
#!/usr/bin/bash
# EDIT from comments below
# expanding from a one liner to a better script...
$RVM_PATH=$HOME/.rvm/scripts
# install 1.9.2-p290 unless it's installed
$RVM_PATH/rvm info 1.9.2-p290 2&>1 >/dev/null || $RVM_SH install 1.9.2-p290
# run startup command inside rvm shell
$RVM_PATH/rvm-shell 1.9.2-p290 -c "cd /home/www-data/rails_app && bundle exec unicorn_rails -p 8000 -E production -c /home/www-data/rails_app/config/unicorn.rb -D"
This should give you the same result.
I need to create a runit service that runs a gem's binary that was installed with rvm, the problem is that a non-login bash shell, which is how runit runs its services does not have the correct path's for rvm. Is there any automatic way of doing this?
I use following script:
#!/bin/sh
exec 2>&1
DIR=/var/www/apps/mega_app/current
export rvm_path=/usr/local/rvm
export rvm_ignore_rvmrc=1
cd $DIR
exec chpst -u user:group /usr/local/rvm/bin/rvm ree exec bundle exec ${DIR}/daemons/mega_daemon.rb
Does su - USERNAME -c '/path/to/script' work? It should preserve the $PATH variables.
I am using daemontools in production to keep the services alive and want to run a Ruby server, not Rails, and without RVM it works well but with RVM I have some issues.
My goal is to start a process by root, make it drop root rights to get another user rights and then spawn a Ruby process with RVM and a specified Ruby version.
Here is the run script I was using until now:
#!/bin/sh
exec 2>&1
cd /app/src
. /usr/local/rvm/scripts/rvm
rvm use 1.9.1-p378
exec setuidgid app_user ruby main.rb
This script works but setuidgid has a major problem: the application will be run by user <x> and group <x> and only this group. If the user is in other groups the process will not have their rights.
So it led me to another approach:
#!/bin/sh
exec 2>&1
cd /app
exec sudo -u app_user rvm 1.9.1-p378 exec ruby main.rb
This one works fine except it is the RVM process which is spawned by daemontools and it does not react when it receives a SIGTERM which is not really nice. Basically it means the service cannot be restarted by hand, which is not good.
I found the answer but looking at the rvmsudo script installed with rvm, here is a working run script:
#!/bin/sh
# redirect stderr to stdout
exec 2>&1
cd /app
# load rvm
. /usr/local/rvm/scripts/rvm
# select ruby version for this application
rvm use 1.9.1
# # depending on your configuration you may need to provide the absolute path to rvm, like that:
# /usr/local/bin/rvm use 1.9.1
# build the exec command line preserving the rvm environment
command="exec sudo -u app_user /usr/bin/env PATH='$PATH'"
[[ -n "${GEM_HOME:-}" ]] && command="${command} GEM_HOME='$GEM_HOME' "
[[ -n "${GEM_PATH:-}" ]] && command="${command} GEM_PATH='$GEM_PATH' "
# this is where your real command line goes
command="${command} ruby main.rb"
# run the application
eval "${command}"
