Neo4j图数据库部署

1、解压jdk文件至当前文件夹(jdk-11.0.15_linux-x64_bin.tar.gz)2、指定java环境变量export JAVA_HOME=jdk-11.0.15 # 注意更改为

1、解压jdk文件至当前文件夹(jdk-11.0.15_linux-x64_bin.tar.gz)

2、指定java环境变量

export JAVA_HOME=jdk-11.0.15 # 注意更改为绝对路径nnexport PATH=$JAVA_HOME/bin:$PATH

3、检测java版本

java -versionnn# java version "11.0.15" 2022-04-19 LTSn# Java(TM) SE Runtime Environment 18.9 (build 11.0.15+8-LTS-149)n# Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.15+8-LTS-149, mixed mode)

4、解压图数据库文件至当前文件夹(neo4j-community-4.4.8-unix.tar.gz)

tar -zxvf neo4j-community-4.4.8-unix.tar.gz

5、更改图数据库配置（打开./conf/neo4j.conf文件）

• 去掉注释的#

• 将7474更改为现场可用的端口号，并去掉注释#

6、启动图数据库

# 进入图数据库文件夹中的bin目录，输入以下命令启动 默认是7474端口n./neo4j startnn# Directories in use:n# home: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8n# config: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/confn# logs: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/logsn# plugins: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/pluginsn# import: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/importn# data: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/datan# certificates: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/certificatesn# licenses: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/licensesn# run: /data/KnowledgeGraph/graphdb/neo4j-community-4.4.8/runn# Starting Neo4j.n# Started neo4j (pid:224236).
