问题
This is my problem. I have copied graph.db for a backup. Neo4j was started when I did that.
After that I deleted graph.db and neo4j started a new one. Neo4j is working fine, no problems. But when wanted to copy again graph.db (the backup one) I get:
Starting Neo4j Server...WARNING: not changing user
waiting for server to be ready... Failed to start within 120 seconds.
I have uninstalled and installed again neo4j and it does not work.
I think is a problem of permissions... If yes how to solve it? I have tried to change permissions with chmod but it does not work... Someone can help me with the code for changing the permissions or configure neo4j with good permissions.
On the log: this appears multiple times:
2014-08-14 15:27:58.102+0000 INFO [API] Setting startup timeout to: 120000ms based on -1
Detected incorrectly shut down database, performing recovery..
Any other suggestion? Thank you for your help.
回答1:
Try to use
bin/neo4j start-no-wait
instead of
bin/neo4j start

As commented before the data was corrupted. It was impossible to recover it.
The correct way to do the backup is: link
Never copy the files while running the database.
We need to zip the graph.db file and then copy it in another location as a backup.
For restore stop the database just delete recursively graph.db and unzip the backup.
Sadly the first data could not be restored...
