Neo4j Getting Started Tutorial-(Install, configure)

Note: Find a lot of tutorials on the web, found that they are not suitable for 0 basic users, so they wrote a bit. The
1.x version is recommended, and the number of functions tested by 2.3.3 is abandoned. Install startup Download the tar package and go to the bin and run./neo4j open localhost:7474 in the URL to use the location setting of the configuration database.

Note: code to modify the database, it appears that each restart neo4j to be displayed in the WebAdmin, it is possible that data synchronization is slow Simple instance (Java Operation neo4j)
