Please I have two instances of symmetricds running on my vm using the commands: 

bin/sym --port 9000
bin/sym --port 4000

but I want to be able to run both instances through the linux service. I have tried installing the service using 'bin/sym_service install' in the respective directories. But it's not working and when I try to start the server I get an error stating that the port is in use.

How can I set up the linux service to use different ports?

To run multiple services of SymmetricDS on the same machine, you will need to:

  • Set unique port numbers for http, https, and jmx in conf/symmetric-server.properties.
  • Set unique service name for wrapper.name in conf/sym_service.conf

Then you can run "bin/sym_service install" to install the init script. On a side note, consider if it makes sense to run multiple nodes inside the same instance by placing multiple engine.properties files in the "engines" directory.

Find out which program is listening to the used port and kill it with kill -9 PROCESS_NUMBER. Then try again.

To run on a different port execute bin/sym --port 3000 server as stated in symmetricds.org/doc/3.10/html/user-guide.html#_sym_launcher

  • Thanks for your response. The issue is the default port used by symmetricDS is 31415. So there's a clash as the two instances are trying to utilize the same port. so if i can specify the ports to be used by the different instances it will work, but i don't know how to do that – Ewomazino Ukah Jul 16 '19 at 11:42
  • Two instances are not needed. You can register more than one symmetricDs engine under the same instance by providing several `symmetric-ds-*.properties` files – Boris Pavlović Jul 16 '19 at 11:49
  • yeah i was able to get ```bin/sym --port 3000``` to work but i could not figure out how to set the ports when using the linux service – Ewomazino Ukah Jul 16 '19 at 13:06
