In the meantime, you can start your project when you SSH into the NAS. My project has a 'www' script which bootstraps my project, so to start I simply type 'node bin/www' from the project directory. But, it only runs while I'm logged in, and if I log out for any reason, the process dies. That's hardly useful when I'm away from home, or on a different PC. So I decided to have a look at starting my project as a Linux service.
After doing a lot of research into how Synology does services, and a few failed attempts at init scripts, I found that Synology DSM (since version 5 perhaps) bundles Upstart, which is a neat little tool to deal with services on Linux. It's most prevalent on Debian and derivatives (notably Ubuntu). So, here's how I got my node.js application running on startup by using Upstart.
Step 1. Create an Upstart script.
Upstart scripts live in /etc/init by default, and that's also the place they live on your Synology NAS. You name the script 'servicename.conf', where 'servicename' is whatever you want it to be called. I called mine 'foobar' because I'm inventive like that, so the file is /etc/init/foobar.conf.
You can be as simple or as comprehensive as you like. I started by using a very simple script, like the one below.
Step 2. Start the service manually
The best part about keeping it simple is that you are more likely to get it running. If there is an error in your script, it won't start and it won't tell you why. It will just say the service could not be found.
To start the script, just type start foobar from the terminal. If it's happy, you'll see the process start and the PID displayed on the console. To stop it again, type 'stop foobar'.
Step 3. Check the script will auto-start
If you pass step 2 OK, then this is just a formality. The script will start when you restart your box. When ready type 'shutdown -r now' and allow your NAS to reboot. When it comes up again, you will be able to see that your service is running by hitting the URL, or by checking the logs which, by default, go to /var/log/upstart - all sysout from your process will go here.
That was exactly what I was searching for, thanks!
ReplyDeleteI didn't tried a reboot of my NAS, but the start command didn't worked with setuid, but worked with default, although it's bad (as you mentioned).
Furthermore I run my scripts with foreverjs/forever, so they restart on script failure, too.
Synology deleted all my custom scripts from /etc/init after system update. :(
ReplyDeleteMe too...did you find a solution?

This is just fantastic!! Worked wonderfully well, although I ran into an issue. I had a different user and group assigned to my folder with my server, so the /var/log/upstart/.log file always said the module could not be found. Had to use chown root:root and chmod 755 to make sure those files were accessible by the http user, then I was able to get the script to run. I even went so far as to move the files into a directory I created in /usr. Now my path to them is /usr/github/ and that works great.
ReplyDeleteThanks for posting this!
I made a script. start manually works fine. But the service does not start with synology. I need to manually set it every time after boot.
ReplyDeleteTo survive an update startup scripts should be located in /usr/local/etc/rc.d and need to be init script format (a shell script that handles the start/stop commands). Different from the above conf format. The Synology 3rd party developer guide has a section on start up scripts (even if it's about creating packages, it's a useful document) https://global.download.synology.com/download/Document/DeveloperGuide/DSM_Developer_Guide.pdf
