railsweb-rvm-init's Introduction

Debian init script for rails web servers

Yep, here comes another init script for rails-based web servers.

It allows you to:

start, stop, restart, and reload unicorn for multiple sites running on the same server;
use a separate RVM environment for each specific site;
use unicorn, puma, or any other application server;
control each site without requiring root permissions (makes it easy to use init script in capistrano deploy process).

Usage:

copy railsweb to /etc/init.d/
enable it: update-rc.d railsweb defaults
create configuration files in /etc/railsweb/ directory

Distinguish between commands to reopen logs for unicorn

Hey there,

I don't know you'd be willing to add this, since you are writing these scripts for unicorn AND puma.
But for production use - at lease for us - it is important to distinguish between 'USR1' and 'USR2'-signals send to the unicorn.

USR1 will reopen logs - important for log rotation (at least for unicorn, don't know about puma)

USR2 will hot-reload the app and exchange the master (for both puma and unicorn)

Therefore I changed reload to actually send USR2 and added another task reopen like this:

    reopen)
        EXIT_CODE=0
        for SITE in $SITES; do
            unset $CONFIG_VARS
            . $CONFIGPATH/$SITE.conf
            echo -n "Reopening logs for $SITE ... "
            PID=`check_pidfile $RAILS_SERVER $RAILS_SERVER_PID`
            if [[ "$PID" != "0" ]]; then
                kill -USR1 $PID
                if [[ "$?" = "0" ]]; then
                    echo "done"
                else
                    echo "failed"
                    EXIT_CODE=3
                fi
            else
                echo "not running!"
            fi
        done
        exit $EXIT_CODE
        ;;

Perhaps something you might consider?

Cheers, Tim
