Neo4j is a highly scalable graph database that runs over all the common platforms; it can be used as is or can be embedded inside applications as well. The following recipe will show you how to set up a single instance of Neo4j over the Linux operating system.
Perform the following steps to get started with this recipe:
Download the community edition of Neo4j from http://www.neo4j.org/download for the Linux platform:
$ wget http://dist.neo4j.org/neo4j-community-2.2.0-M02-unix.tar.gzCheck whether Java is installed for your operating system or not by typing this in the shell prompt:
$ echo $JAVA_HOMEIf this command produces no output, install JDK/JRE for your Linux distribution and also set the
JAVA_HOMEpath
Now, let's install Neo4j over the Linux operating system, which is simple, as shown in the following steps:
Extract the TAR file by using the following command:
$ tar –zxvf neo4j-community-<version>-unix.tar.gz $ ls
Go to the
bindirectory under the root folder:$ cd <neo4j-community-version>/bin/Start the Neo4j graph database server:
$ ./neo4j startCheck whether Neo4j is running or not by using the following command:
$ ./neo4j statusNeo4j can also be monitored using the web console. Open
http://<ip>:7474/webadmin, as shown in the following screenshot:
The preceding diagram is a screenshot of the web console of Neo4j, through which the server can be monitored and different Cypher queries can be run on the graph database.
Neo4j comes with prebuilt binaries over the Linux operating system, which can be extracted and run over. Neo4j comes with both web-based and terminal-based consoles, over which the Neo4j graph database can be explored.
During installation, you may face several kind of issues, such as the maximum number of files you can keep open at once and so on. For more information, check out http://neo4j.com/docs/stable/server-installation.html#linux-install.
