Linux上部署neo4j笔记内容

1. 安装Java 1.8

1. 下载neo4j

wget http://we-yun.com/download/Neo4j-Releases/3.2.0/neo4j-communitygz

1. 解压

tar zxvf neo4j-community-3.2.0-unix.tar.gz

4.修改目录

mv neo4j-community-3.2.0 neo4j

5.配置环境变量

vi /etc/profile

添加：

export NEO4J_HOME=/opt/neo4j export PATH=$PATH:$NEO4J_HOME/bin

使之生效

source /etc/profile

6.

vi /etc/security/limits.conf

neo4j soft nofile 40000 neo4j hard nofile 40000

7.启动服务

neo4j start

查看状态

neo4j status

停止服务

neo4j stop

8.修改配置文件，允许远程访问web

cd /opt/neo4j/conf/

vi

dbms.connectors.default_listen_address=0.0.0.0(即将# 删除)

之后重启服务，在本地访问

http://10.10.0.156:7474/

以neo4j/neo4j登录成功后，修改密码：123456

9.测试

cd /opt/neo4j/bin

./cypher-shell

此时，根据提示输入用户名neo4j,密码123456，登录到操作命令行下，创建简单的父子关系图

neo4j> CREATE (A {id:1,name:'张飞'}), (B {id:2,name:'张小二'}), (C {id:3,name:'张三'}), (D {id:4,name:'张凯'}),(E {id:5,name:'张雨'}),(A)-[:Son]->(B),(A)-[:Son]->(C),(B)-[:Son]->(D),(C)-[:Son]->(E);

执行如下查询：

neo4j> match (n) return n;

返回所有节点和关联

+------------------------+ | n | +------------------------+ | ({name: "张飞", id: 1}) | | ({name: "张小二", id: 2}) | | ({name: "张三", id: 3}) | | ({name: "张凯", id: 4}) | | ({name: "张雨", id: 5}) | +------------------------+
