Neo4j docker 部署

想要运行简单测试一下neo4j，就直接使用docker创建了一个容器，并用cypher-shell本地连接neo4j，创建图进行测试。

1 开启docker

sudo systemctl start docker

2 拉取镜像源

sudo docker pull neo4j # 默认latest版本

3 查看本地镜像，检验是否拉取成功

sudo docker images

4 创建容器并运行

在/home/neo4j目录下分别创建 data、logs、conf、import 四个目录

• data，数据存放的文件夹
• logs，运行的日志文件夹
• conf，数据库配置文件夹
• import，为了大批量导入csv来构建数据库，只能导入.csv格式的文件，要放到这个文件夹下

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 检查容器是否构建成功

sudo docker ps -a

6 进入到容器内部

sudo docker exec -it 容器id bash
# 例如：sudo docker exec -it ea6ecd2e43ac bash

7 运行客户端cypher-shell

./bin/cypher-shell

8 cypher图创建，图查询

neo4j@neo4j> CREATE (node1:Router {ip:'127.0.0.1'}),(node2:Router {ip:'127.0.0.2'}),(node3:Router {ip:'127.0.0.3'}),(node4:Router {ip:'127.0.0.4'}),(node5:Router {ip:'127.0.0.5'}),(node6:Router {ip:'127.0.0.6'}),(node7:Router {ip:'127.0.0.7'}),(node8:Router {ip:'127.0.0.8'}),(node9:Router {ip:'127.0.0.9'}),(node1)-[:Connect]->(node4),(node2)-[:Connect]->(node5),(node3)-[:Connect]->(node6),(node4)-[:Connect]->(node7),(node4)-[:Connect]->(node8),(node5)-[:Connect]->(node8),(node6)-[:Connect]->(node9);

9 退出cypher-shell和容器

:exit # 退出cypher-shell
exit # 退出容器

10 容器停止运行

sudo docker stop 容器id
