OS: Amazon Linux 2
Java: openjdk 17.0.8 2023-07-18 LTS
      OpenJDK Runtime Environment Corretto-17.0.8.7.1 (build 17.0.8+7-LTS)
      OpenJDK 64-Bit Server VM Corretto-17.0.8.7.1 (build 17.0.8+7-LTS, mixed mode, sharing)
Neo4j version: 5.11.0
GDS version: 2.4.4
Neo4j RPM installer and default file structure

debug.log显示了一个很长的Failed to load .... from plugin jar/var/lib/neo4j/plugins/neo4j-graph-data-science-2.4.4.jar: java.lang.NoClassDefFoundError: ....列表(太长,无法包含完整的错误日志)
GDS Enterprise安装在辅助服务器上。
我尝试过使用graphicscience neo4j-graph-data-science-2.4.4.zip和github neo4j-graph-data-science-2.4.4.jar安装

  • 在默认的NEO4J_HOME路径中,/var/lib/neo4j/plugins
  • 解压时默认命名,neo4j-graph-data-science-2.4.4.jar
  • 所有者:neo4j组:Neo4j
  • 使用权限:0775
  • 辅助服务器配置:
server.directories.plugins=/var/lib/neo4j/plugins
initial.dbms.default_primaries_count=1
initial.dbms.default_secondaries_count=1
server.default_listen_address=0.0.0.0
server.default_advertised_address= SERVER IP
dbms.cluster.discovery.endpoints= LIST OF ALL SERVERS IPS
server.bolt.enabled=true
server.http.enabled=true
initial.server.mode_constraint=SECONDARY
server.cluster.system_database_mode=SECONDARY
dbms.security.procedures.unrestricted=apoc.*,gds.*
dbms.security.procedures.allowlist=apoc.coll.*,apoc.load.*,apoc.*,gds.*
gds.enterprise.license_file=/var/lib/neo4j/licenses/gds_activation_key
dbms.routing.enabled=true
dbms.routing.default_router=SERVER

-primary/writer服务器配置:

server.directories.plugins=/var/lib/neo4j/plugins
initial.dbms.default_primaries_count=1
initial.dbms.default_secondaries_count=1
server.default_listen_address=0.0.0.0
server.default_advertised_address= SERVER IP
dbms.cluster.discovery.endpoints= SERVER IP
server.bolt.enabled=true
server.http.enabled=true
dbms.security.procedures.unrestricted=apoc.*
dbms.security.procedures.allowlist=apoc.coll.*,apoc.load.*,apoc.*
dbms.routing.enabled=true
dbms.routing.default_router=SERVER

我可以启动集群并在默认的http://IP:7474访问UI
当我运行RETURN gds.version();时,我得到一个systax错误:Neo.ClientError.Statement.SyntaxError Unknown function 'gds.version' (line 1, column 8 (offset: 7)) "RETURN gds.version() AS gds.version()"
我可以使用SHOW SERVERS YIELD *;确认群集配置我可以使用RETURN apoc.version();确认APOC安装
这到底是怎么回事

尝试在您的“主”服务器上修改neo4j.conf以允许GDS过程:

dbms.security.procedures.unrestricted=apoc.*,gds.*
dbms.security.procedures.allowlist=apoc.coll.*,apoc.load.*,apoc.*,gds.*
