1、解壓jdk文件至當前文件夾(jdk-11.0.15_linux-x64_bin.tar.gz)

2、指定java環境變量

export JAVA_HOME=jdk-11.0.15 # 注意更改為絕對路徑nnexport PATH=$JAVA_HOME/bin:$PATH

3、檢測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、解壓圖數據庫文件至當前文件夾(neo4j-community-4.4.8-unix.tar.gz)

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

5、更改圖數據庫配置（打開./conf/neo4j.conf文件）

• 去掉注釋的#

• 將7474更改為現場可用的端口號，并去掉注釋#

6、啟動圖數據庫

# 進入圖數據庫文件夾中的bin目錄，輸入以下命令啟動 默認是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).
