If you want to run a simple test of neo4j, you can directly use docker to create a container, connect to neo4j locally with cypher-shell, and create a graph for testing.
1 start docker
sudo systemctl start docker
2 Pull the image source
sudo docker pull neo4j # 默认latest版本
3 Check the local mirror to check whether the pull is successful
sudo docker images
4 Create a container and run it
Create four directories of data, logs, conf, and import in the /home/neo4j directory
- data, the folder where the data is stored
- logs, the running log folder
- conf, the database configuration folder
- import, in order to import csv in large quantities to build a database, only files in .csv format can be imported, which should be placed in this folder
sudo docker run -d --name container_name -p 27474:7474 -p 27687:7687 -v /home/neo4j/data:/data -v /home/neo4j/logs:/logs -v /home/neo4j/conf:/var/lib/neo4j/conf -v /home/neo4j/import:/var/lib/neo4j/import --env NEO4J_AUTH=neo4j/password neo4j
-d --name container_name //-d表示容器后台运行 --name指定容器名字
-p 27474:7474 -p 27687:7687 //映射容器的端口号到宿主机的端口号；27474 为宿主机端口
-v /home/neo4j/data:/data //把容器内的数据目录挂载到宿主机的对应目录下
-v /home/neo4j/logs:/logs //挂载日志目录
-v /home/neo4j/conf:/var/lib/neo4j/conf //挂载配置目录
-v /home/neo4j/import:/var/lib/neo4j/import //挂载数据导入目录
--env NEO4J_AUTH=neo4j/password //设定数据库的名字的访问密码
neo4j //指定使用的镜像
5 Check whether the container is built successfully
sudo docker ps -a
6 Access to the interior of the container
sudo docker exec -it 容器id bash
# 例如：sudo docker exec -it ea6ecd2e43ac bash
7 Run the client cypher-shell
./bin/cypher-shell
8 Cypher graph creation, graph query
