Neo4j not starting on my ec2 instance after doing some config chnages

Neo4j Graph Platform Browser
1

All I did was tried using the APOC plugin , so did few changes in my config file , those are mentioned below ->

dbms.security.procedures.unrestricted=apoc.*
dbms.security.procedures.whitelist=apoc.*,apoc.coll.*,apoc.load.*

Also I added a jar file in the plugin folder of var/neo4j
earlier before these changes it was running perfectly fine, but now when trying to start it throws these errors ->

Start by checking plugins folder: /var/lib/neo4j/plugins so you have the expected plugins (and the right versions, it should be apoc-5.9.0-core.jar for neo4j 5.9.0).

Also, check what is up with the warning that you are using an unsupported Java Runtime.

In addition, is there reason to suspect that it takes a long time for neo4j to start? Like did you process a lot of writes (like initial import of data) or make an un-graceful shut down of the neo4j process during the restart of the service? It may be systemd not allowing the service enough time to stop/start. Check the service file and allow it few more minutes before systemd terminates the service.

Thanks for the response, so as u suggested I started using the apoc 5.9.0 file and replaced it the plugins folder also created a new service file overe here ->

/etc/systemd/system/neo4j.service

whose contents are as follows ->


[Unit]
Description=Neo4j Graph Database

[Service]
TimeoutStartSec=300
TimeoutStopSec=300
ExecStart=/usr/share/neo4j/bin/neo4j

[Install]
WantedBy=default.target

and also updated the java runtimew version which is set to openjdk 17, and on executing ->

echo $JAVA_HOME
my output is 
/usr/lib/jvm/java-17-openjdk-amd64

still when trying to start neo4j on my instance using the command sudo systemctl start neo4j it fails to start and the logs are given below ->

Can you also check the neo4j.log file / journalctl -e -u neo4j ? There is maybe additional info that may help point us in the right direction. That waring Cannot invoke "org.eclipse..." does not really tell me much.

I ran the command -> sudo journalctl -e -u neo4j and got the below output ->

This should be changed:

'dbms.security.procedures.whitelist'. It is replaced by 'dbms.security.procedures.allowlist'.

Also check your plugins directory agan so no old/other jar files are around:

Some jar procedure files (apoc-4.4.0.20-all.jar) are invalid,

I hope it is just those things and that you will be up and running again soon.

so I replaced the command as suggested and also checked and no old jar files were present butt still when trying to start neo4j there are errors and it doesn't starts

command executed -> sudo systemctl start neo4j
output generated ->

I think the status=2/INVALIDARGUMENT is due to your ExecStart in the service definition. Now it would be good to go back to the original one. If I recall it correctly it should have something like this in it:

ExecStart=/usr/bin/neo4j start
ExecStop=/usr/bin/neo4j stop
ExecReload=/usr/bin/neo4j restart

I think you would get it if you re-install the neo4j package.
