Neo4j導(dǎo)出dump文件指南,包括暫停服務(wù)、打開cmd、使用正確命令及注意事項,確保命令和數(shù)據(jù)庫名正確無誤?kukuk

Neo4j導(dǎo)出dump文件

1.首先需要暫停neo4j服務(wù)

才可以導(dǎo)出文件

neo4j stop

2.在neo4j安裝目錄下

的bin文件中打開cmd

3.不同版本的導(dǎo)入命令不一樣

網(wǎng)上基本上給的是4.0版本以下的，命令如下：

neo4j-admin dump --database=neo4j --to=D:/Backup_graphData/xxxx.db.dump

–database= 需要導(dǎo)出的數(shù)據(jù)庫名稱
–to= 保存文件的路徑

4.目前neo4j已經(jīng)更新到5.0版本了

新版本的導(dǎo)出命令如下

neo4j-admin database dump --to-path="D:/test/" neo4j

--to-path 保存文件的路徑

neo4j 數(shù)據(jù)庫名字

可以查看命令的具體參數(shù)信息
neo4j-admin database dump [-h] [--expand-commands] [--verbose] [--overwrite-destination[=true|false]]
                          [--additional-config=<file>] [--to-path=<path> | --to-stdout] <database>

DESCRIPTION

Dump a database into a single-file archive. The archive can be used by the load command. <to-path> should be a
directory (in which case a file called <database>.dump will be created), or --to-stdout can be supplied to use standard
output. If neither --to-path or --to-stdout is supplied `server.directories.dumps.root` setting will be used as
destination. It is not possible to dump a database that is mounted in a running Neo4j server.

PARAMETERS

      <database>          Name of the database to dump. Can contain * and ? for globbing. Note that * and ? have
                            special meaning in some shells and might need to be escaped or used with quotes.

OPTIONS

      --additional-config=<file>
                          Configuration file with additional configuration.
      --expand-commands   Allow command expansion in config value evaluation.
  -h, --help              Show this help message and exit.
      --overwrite-destination[=true|false]
                          Overwrite any existing dump file in the destination folder.
                            Default: false
      --to-path=<path>    Destination folder of database dump.
      --to-stdout         Use standard output as destination for database dump.
      --verbose           Enable verbose output.

5.注意點

一定要以管理員身份打開cmd，否則就會一直報錯：

Invalid value for positional parameter at index 0 (<database>): Invalid database name 'neo4j '. (java.lang.IllegalArgumentException: Database name 'neo4j ' contains illegal characters. Use simple ascii characters, numbers, dots, question marks, asterisk and dashes.)

很莫名其妙的在數(shù)據(jù)庫名后面加一個空格。

ps：

盡量還是看官方文檔吧，網(wǎng)上的資料有些已經(jīng)過時了
