Cannot start Neo4j - getting unable to bind to port

问题

I am using mac os, every time I am trying to start Neo4j I am getting this error

Unable to bind to port. Are you running another Neo4j process on this computer?

tried to check the default port

lsof -i :5001

but nothing is bind to that port

same result checking the activity monitor shows that neo4j not running

回答1:

Is 5001 your browser port ?

I would check if there is usage on the following :

Port 7474 (neo4j browser) : lsof -i -n -P | grep 7474

Port 1337 (neo4j-shell): lsof -i -n -P | grep 1337

Same for 7473

For the shell, for example Tunnelbclick is using 1337 and sometimes conflicts with neo4j.

If it doesn't work, try to kill your java processes :

sudo killall -9 java
