neo4j docker 容器 neo4j-admin import 导入csv数据

一、创建docker容器

1、先创建两个目录 一个data 用来挂载数据库文件，一个import 用来存放导入的csv文件

执行命令：
docker run -itd --name neo4j -p 7474:7474 -p 7687:7687 --env=NEO4J_AUTH=none -v import的绝对路径:/var/lib/neo4j/import -v data的绝对路径:/data neo4j

二、删除data/databases/graph.db/ 下的所有文件

neo4j-admin import 只能在空库下执行

三、新建csv文件

students.csv

studentId:ID,name,age:int,:LABEL
11,"学生一",18,Student
12,"学生二",16,Student
13,"学生三",17,Student
14,"学生四",19,Student

classes.csv

classId:ID,name,:LABEL
21,"一班",Class
22,"二班",Class
23,"三班",Class
24,"四班",Class

teacher.cav

teacherId:ID,name,:LABEL
31,"赵老收",Teacher
32,"王老师",Teacher

relations.csv

:START_ID,:END_ID,score,:TYPE
11,21,100,Study_in
12,21,100,Study_in
13,22,100,Study_in
14,23,100,Study_in
11,31,100,Teach
12,32,100,Teach
31,21,100,Work_in
32,22,100,Work_in

四、执行导入

docker exec -it neo4j bash
进入容器
执行命令 bin/neo4j-admin import
root@b688ef5e8f80:/var/lib/neo4j# bin/neo4j-admin import --nodes =import/students.csv --nodes=import/classes.csv --nodes=import/teacher.csv --relationships=import/relations.csv --database=graph.db
