      2. 
         1. first line's port use to connect neo4j sever, such as : some application yml will config this port
            
         2. second line use to config the port that neo4j management center browser 
            

4. Place the extracted files in a permanent home on your server. The top level directory is referred to as NEO4J_HOME.

   1. To run Neo4j as a console application, use: /bin/neo4j console.

   2. To run Neo4j in a background process, use: /bin/neo4j start.

5. Visit http://:7474 in your web browser.

6. Connect using the username 'neo4j' with default password 'neo4j'. You’ll then be prompted to change the password.
