本文详细介绍Neo4j社区版的安装步骤与配置方法，包括环境检查、内存配置、端口设定及启动命令，适用于初学者快速上手。

注意事项

需要配置 INSTALL_PATH
需要准备配置文件(可先解压一份出来修改),对应修改dbms.memory.heap.initial.size, dbms.memory.heap.max.size, dbms.memory.pagecache.size, dbms.connector.bolt.listen_address=:, dbms.connector.http.listen_address=:, dbms.connector.https.listen_address=: 后面增加脚本变量名
dbms.connector.bolt.enabled=true, dbms.connector.http.enabled=true, dbms.connector.https.enabled=true 需要设置
安装完成后,bin目录执行 neo4j-admin memrec 命令查看内存推荐配置(例64GB可以配20G的heap,24G的pagecache)
