Neo4j是一个原生图数据库，它存储和处理数据的方式与你刚在浏览器中画的关系图几乎一样：用节点（如“基努·里维斯”）、关系（如“出演”）和属性（如“角色：尼奥”）来构建数据模型。这种结构让它特别擅长快速分析和查询数据之间的复杂联系。

为什么Neo4j这么快？

它的优势在处理关联数据时尤为明显。与传统关系型数据库（如MySQL）需要使用复杂的“连接”操作来查询关系不同，Neo4j在存储数据时，就直接把“关系”作为一等公民保存了下来。这使得查询如“朋友的朋友”这种多层关系时，速度能比传统数据库快上千倍。

一、安装步骤

sudo apt-get update
sudo apt install neo4j-enterprise=1:5.26.14
sudo systemctl start neo4j
sudo systemctl enable neo4j
sudo systemctl status neo4j
ss -ltnp|grep 7474

vim /etc/neo4j/neo4j.conf
#开放远程连接
server.default_listen_address=0.0.0.0
server.bolt.listen_address=:7687
server.http.listen_address=:7474
#重启生效
sudo systemctl restart neo4j
sudo systemctl status neo4j

二、UI界面登陆

http://192.168.119.100:7474
初始登陆要更改密码
先输入默认密码 neo4j
再更改新密码 xxxxxxx

五、备份

Neo4j‑5.x 社区版执行 neo4j‑admin database dump，数据库运行状态下不允许 dump 导出，必须停止 Neo4j 服务；企业版才支持在线 dump。

systemctl stop neo4j
systemctl status neo4j

确认状态为 inactive(dead) 之后再执行导出

neo4j-admin database dump neo4j --to-path=/root/neo4j_backup
