Change default port number

Hi,

Is there any easy way to change port number instead of reinstalling the software?

Thank you!

Hi @kortal, you can change the default port number in cryosparc_master/config.sh file.

  1. Stop cryoSPARC with cryosparcm stop
  2. Edit cryosparc_master/config.sh and look for the line that looks like export CRYOSPARC_BASE_PORT=xxxxx. Change xxxxx to the desired port value
  3. Exit/log out of the current terminal and log back in
  4. Restart cryoSPARC with cryosparcm start

Let me know how that goes.

Hi @wonderful, this means a component that runs cryoSPARC Live failed to start. Can you send me the logs for it via this command?

cryosparcm log command_rtp

(Afterwards press Ctrl+C to exit)

@wonderful from the logs it looks like this is working now, can you confirm? If not, please restart your machine. Then run these two commands and send me the output:

hi,@nfrasser,above is the output that when I change the port and as your way to restart cryosparc.it seems didn’t work,so I change the port back.

@wonderful ah I see, this indicates that there is another process running on one of ports that cryoSPARC requires. To fix this, stop cryoSPARC and run these commands (substitute the port numbers with the correct port - e.g., if your base port is 40000, instead of 39000, 39001, etc; use 40000, 40001, 40002, etc.):

lsof -i :39000
lsof -i :39001
lsof -i :39002
lsof -i :39003
lsof -i :39005
lsof -i :39006

If you’ll see output like this for one of the commands:

lsof -i :39000
COMMAND   PID     USER        FD   TYPE     DEVICE SIZE/OFF NODE NAME
node    27752 cryosparcuser   15u  IPv4 2206290935      0t0  TCP *:39000 (LISTEN)
node    27752 cryosparcuser   16u  IPv4 2321775470      0t0  TCP localhost:39000->localhost:52142 (ESTABLISHED)

This means there is a process bound to that port so that cryoSPARC can’t use it (in this case node with process ID 27752). Kill that process and re-run the lsof commands until there is no more output.

Then start cryoSPARC. Send me any output you’re not sure about. Hope that helps!

Nick
