# Puma as a service using Upstart
|
||
|
|
|
||
|
|
Manage multiple Puma servers as services on the same box using Ubuntu upstart.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
# Copy the scripts to services directory
|
||
|
|
sudo cp puma.conf puma-manager.conf /etc/init
|
||
|
|
|
||
|
|
# Create an empty configuration file
|
||
|
|
sudo touch /etc/puma.conf
|
||
|
|
|
||
|
|
## Managing the jungle
|
||
|
|
|
||
|
|
Puma apps are referenced in /etc/puma.conf by default. Add each app's path as a new line, e.g.:
|
||
|
|
|
||
|
|
```
|
||
|
|
/home/apps/my-cool-ruby-app
|
||
|
|
/home/apps/another-app/current
|
||
|
|
```
|
||
|
|
|
||
|
|
Start the jungle running:
|
||
|
|
|
||
|
|
`sudo start puma-manager`
|
||
|
|
|
||
|
|
This script will run at boot time.
|
||
|
|
|
||
|
|
Start a single puma like this:
|
||
|
|
|
||
|
|
`sudo start puma app=/path/to/app`
|
||
|
|
|
||
|
|
## Logs
|
||
|
|
|
||
|
|
Everything is logged by upstart, defaulting to `/var/log/upstart`.
|
||
|
|
|
||
|
|
Each puma instance is named after its directory, so for an app called `/home/apps/my-app` the log file would be `/var/log/upstart/puma-_home_apps_my-app.log`.
|
||
|
|
|
||
|
|
## Conventions
|
||
|
|
|
||
|
|
* The script expects:
|
||
|
|
* a config file to exist under `config/puma.rb` in your app. E.g.: `/home/apps/my-app/config/puma.rb`.
|
||
|
|
* a temporary folder to put the PID, socket and state files to exist called `tmp/puma`. E.g.: `/home/apps/my-app/tmp/puma`. Puma will take care of the files for you.
|
||
|
|
|
||
|
|
You can always change those defaults by editing the scripts.
|
||
|
|
|
||
|
|
## Here's what a minimal app's config file should have
|
||
|
|
|
||
|
|
```
|
||
|
|
pidfile "/path/to/app/tmp/puma/pid"
|
||
|
|
state_path "/path/to/app/tmp/puma/state"
|
||
|
|
activate_control_app
|
||
|
|
```
|
||
|
|
|
||
|
|
## Before starting...
|
||
|
|
|
||
|
|
You need to customise `puma.conf` to:
|
||
|
|
|
||
|
|
* Set the right user your app should be running on unless you want root to execute it!
|
||
|
|
* Look for `setuid apps` and `setgid apps`, uncomment those lines and replace `apps` to whatever your deployment user is.
|
||
|
|
* Replace `apps` on the paths (or set the right paths to your user's home) everywhere else.
|
||
|
|
* Uncomment the source lines for `rbenv` or `rvm` support unless you use a system wide installation of Ruby.
