Neo4j error, Failed to start Neo Server on port[80]

Question

I have a Neo4j database using port7474, this database works fine. Then I got a new database,in the beginning, it also worked, but after several days, it can not start. The error messages show "Failed to start Neo Server on port[80]", so I change the \conf\neo4j-server.properties, from port 80 to port 7474, still can not start.

What is the probelm? The old neo4j database can still work, what is wrong with the new one?

Answer 1

This error message indicates that there is one neo4j-server.properties file setting the port to 80. Maybe you've downloaded and installed multiple versions of Neo4j to different locations. Use a global search e.g. find / -name neo4j-server.properties (or do the same via point&click when being on Windows) to identify them.
