Neo4j 安装 APOC 和图形算法 Neo.ClientError.Procedure.ProcedureRegistrationFailed

Question

我在使用 APOC 和图形算法插件时遇到了一些问题。我按照说明将 .jars 放入 {NEO4j_HOME}/plugins 并更改了 {NEO4j_HOME}/conf/neo4j.conf

中的设置

dbms.directories.data=/Users/mlo/neo4j-community-3.3.1/data
dbms.directories.plugins=/Users/mlo/neo4j-community-3.3.1/plugins
dbms.directories.certificates=/Users/mlo/neo4j-community-3.3.1/certificates
dbms.directories.logs=/Users/mlo/neo4j-community-3.3.1/logs
dbms.directories.lib=/Users/mlo/neo4j-community-3.3.1/lib
dbms.directories.run=/Users/mlo/neo4j-community-3.3.1/run

dbms.security.auth_enabled=false
dbms.security.procedures.unrestricted=algo.*
dbms.security.procedures.unrestricted=apoc.*

一些程序有效。

CALL apoc.help('dijkstra')
CALL algo.list()

但是，大多数存储过程根本不起作用。

Neo.ClientError.Procedure.ProcedureRegistrationFailed
algo.unionFind is unavailable because it is sandboxed and has dependencies outside of the sandbox. Sandboxing is controlled by the dbms.security.procedures.unrestricted setting. Only unrestrict procedures you can trust with access to database internals.
algo.pageRank is unavailable because it is sandboxed and has dependencies outside of the sandbox. Sandboxing is controlled by the dbms.security.procedures.unrestricted setting. Only unrestrict procedures you can trust with access to database internals.

谁能指出我的设置哪里出了问题？谢谢。

Answer 1

更改这些行：

dbms.security.procedures.unrestricted=algo.*
dbms.security.procedures.unrestricted=apoc.*

至：

dbms.security.procedures.unrestricted=algo.*,apoc.*

并重启 Neo4j 服务。

Answer 2

根据@bruno-peres 的回答，我在 Arch Linux 和 Neo4j 3.4.0 上遇到了类似的问题（accessing/using Neo4j APOC/Algorithms）。

我使用 APOC (Awesome Procedures for Neo4j) and the Efficient Graph Algorithms for Neo4j，与下载到我的 Neo4j 插件目录的适当版本 .jar 文件；即，

/mnt/Vancouver/apps/neo4j/neo4j-community-3.4.0/plugins/apoc-3.4.0.1-all.jar
/mnt/Vancouver/apps/neo4j/neo4j-community-3.4.0/plugins/graph-algorithms-algo-3.4.0.0.jar

然而，当我尝试运行这个命令时，

CALL algo.pageRank.stream('Metabolism', 'yields',
{iterations:20, dampingFactor:0.85})
YIELD node, score
RETURN node,score order by score desc limit 20

在我的 Neo4j 浏览器中，我收到了这个错误：

Error: Neo.ClientError.Procedure.ProcedureRegistrationFailed

Neo.ClientError.Procedure.ProcedureRegistrationFailed: algo.pageRank is
unavailable because it is sandboxed and has dependencies outside of the
sandbox. Sandboxing is controlled by the    
dbms.security.procedures.unrestricted setting. Only unrestrict 
procedures you can trust with access to database internals.

根据此处接受的答案 (SO 48773505)

我需要对 "neo4j.conf" 文件进行以下编辑，

/mnt/Vancouver/apps/neo4j/neo4j-community-3.4.0/conf/neo4j.conf

取消注释这一行，

dbms.directories.plugins=plugins

和add/edit这一行，

dbms.security.procedures.unrestricted=apoc.trigger.*,apoc.*,algo.*

注意（上图），看来neo4j.conf接受一个

dbms.security.procedures.unrestricted=...

行！有单独的行，例如

dbms.security.procedures.unrestricted=apoc.trigger.*,apoc.*
dbms.security.procedures.unrestricted=algo.*

导致 ... is unavailable because it is sandboxed and has dependencies outside of the sandbox ... 错误！

最后，重启你的 Neo4j server/instance,

neo4j restart
