Explanation of building graph database neo4j in Linux environment

Neo4j (one of the Nosql) is a high-performance graph database (does not support distribution) and is often used in social relationships. There are many introductions to Neo4j on the Internet, so I will not go into details here. Let's briefly talk about installation:

1. Install jdk, no more words:

ubuntu@VM-0-15-ubuntu:~$ java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

2. Download and unzip neo4j (community edition) from the official website, as follows:

ubuntu@VM-0-15-ubuntu:~/taoge/neo4j_db$ ll
total 77504
drwxrwxr-x 3 ubuntu ubuntu 4096 Feb 1 18:20 ./
drwxrwxr-x 8 ubuntu ubuntu 4096 Feb 2 14:56 ../
drwxr-xr-x 11 ubuntu ubuntu 4096 Feb 1 18:21 neo4j-community-3.2.9/
-rw-r--r-- 1 ubuntu ubuntu 79268344 Feb 1 18:17 neo4j-community-3.2.9-unix.tar.gz
ubuntu@VM-0-15-ubuntu:~/taoge/neo4j_db$

3. I built neo4j on Linux and then accessed it with a browser on Windows, so I had to let neo4j listen to all IPs, not just 127.0.0.1. I needed to modify the configuration file. The configuration file is:

ubuntu@VM-0-15-ubuntu:~/taoge/neo4j_db/neo4j-community-3.2.9/conf$ ls
neo4j.conf

To remove the comment of the following line, it will be:

dbms.connectors.default_listen_address=0.0.0.0

In this way, the browser on Windows can be anti-counterfeiting, otherwise neo4j on Linux listens to 127.0.0.1:7474, and Windows can't access it.

4. Start neo4j as follows:

ubuntu@VM-0-15-ubuntu:~/taoge/neo4j_db/neo4j-community-3.2.9/bin$ ls
cypher-shell neo4j neo4j-admin neo4j-import neo4j-shell tools
ubuntu@VM-0-15-ubuntu:~/taoge/neo4j_db/neo4j-community-3.2.9/bin$ ./neo4j start

As you can see, port 7474 is being listened to:

ubuntu@VM-0-15-ubuntu:~/taoge/neo4j_db/neo4j-community-3.2.9/bin$ netstat -nao | grep 7474
tcp 0 0 0.0.0.0:7474 0.0.0.0:* LISTEN off (0.00/0/0)

5. Enter http://ip:7474 (ip is the IP address of the Linux machine) in the Windows browser, then enter the default username neo4j and the default password neo4j, and then change it to the new password as required.

6. Click around, look around, explore, and build a map:

CREATE (English:Book { title:"A book about English",released:2000 })
CREATE (Math:Book { title:"A book about Math",released:2001 })
CREATE (Law:Book { title:"A book about Law",released:2002 })
CREATE (taogeLi:Person { name:"Li Taoge", born:1988 })
CREATE (taogeZhou:Person { name:"Zhou Taoge", born:1989 })
CREATE (taogeWang:Person { name:"Wang Taoge", born:1990 })
CREATE (taogeLi)-[:write { roles: ["co-author"]}]->(English)
CREATE (taogeLi)-[:write { roles: ["co-author"]}]->(Math)
CREATE (taogeLi)-[:like]->(English)
CREATE (taogeLi)-[:like]->(Law)
CREATE (taogeZhou)-[:hate]->(Law)
CREATE (taogeZhou)-[:hate]->(taogeWang)
CREATE (taogeWang)-[:hate]->(taogeZhou)
CREATE (taogeWang)-[:like]->(Law)
RETURN English,Math,Law,taogeLi,taogeZhou,taogeWang

Let’s take a look at the effect:

More will be introduced later. When it comes to unfamiliar things, think more, explore more, and check more information, that is the truth.
