according to documentation:
there are 2 types of APOC
- APOC Core
- APOC Full
first one included in the installation folder($NEO4J_HOME/labs) and for the second one u need to download it("Make sure that the first two version numbers match between Neo4j and APOC").
if u want to go with APOC Core just copy $NEO4J_HOME/labs/apoc-...jar file to the $NEO4J_HOME/plugins
and for APOC Full download the package then put it into $NEO4J_HOME/plugins directory. finally restart.
linux command for APOC Core assuming neo4j installed in /var/lib/neo4j:
sudo cp /var/lib/neo4j/labs/apoc-4.3.0.3-core.jar /var/lib/neo4j/plugins/
sudo chown neo4j:neo4j /var/lib/neo4j/plugins/apoc-4.3.0.3-core.jar
sudo systemctl restart neo4j
