I am currently trying to install Neo4j on my Raspberry Pi. The installation for the latest version worked great so far. When I tried neo4j start I received this error message but was able to resolve it by setting dbms.memory.heap.initial_size=12m and dbms.memory.heap.max_size=12m and dbms.memory.pagecache.size=1g (allthough that feels wrong to me since my Pi has 8GB of memory):
nohup: ignoring input 2021-01-26 21:54:18.409+0000 ERROR Invalid memory configuration - exceeds physical memory. Check the configured values for dbms.memory.pagecache.size and db> 2021-01-26 21:54:18.436+0000 INFO Neo4j Server shutdown initiated by request 2021-01-26 21:54:18.437+0000 INFO Stopped. Now, when I try to start neo4j I get this error in my logs:
nohup: ignoring input Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.neo4j.configuration.GraphDatabaseSettings at org.neo4j.server.NeoBootstrapper.start(NeoBootstrapper.java:105) at org.neo4j.server.NeoBootstrapper.start(NeoBootstrapper.java:90) at org.neo4j.server.CommunityEntryPoint.main(CommunityEntryPoint.java:35) 2021-01-26 22:20:55.271+0000 INFO [o.n.s.CommunityBootstrapper] Neo4j Server shutdown initiated by request 2021-01-26 22:20:55.290+0000 INFO [o.n.s.CommunityBootstrapper] Stopped. I have now been trying to google the problem for a couple hours but I feel like I don't really know what to look for.
My setup:
- Raspberry Pi 4 (8 GB memory)
- Ubuntu Server (
