Store and its lock file has been locked by another process: /var/lib/neo4j/data/databases/graph.db/store_lock

问题

what I did

neo4j console

(work fine)

ctrl-C

upon restarting I have message above.

I delete /var/lib/neo4j/data/databases/graph.db/store_lock

then I have

Externally locked: /var/lib/neo4j/data/databases/graph.db/neostore

Is there any way of cleaning lock ? (short of reinstalling)

回答1:

You can kill the java process and delete the store_lock file. It doesn't seem to harm the database integrity.

Killing the Java process and deleting the store_lock worked for me:

Found the lingering process,

ps aux | grep "org.neo4j.server"

killed it,

kill -9 <pid-of-neo4js-java-process>

and deleted

sudo rm /var/lib/neo4j/data/databases/graph.db/store_lock

Allegedly, just killing the lingering process may do the trick but I went ahead and deleted the lock anyway.
