When you restart your service you’ll notice this warning:

WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.

To fix this, edit this file

sudo nano /etc/security/limits.conf

and add these two entries:

root soft nofile 40000 root hard nofile 40000 neo4j soft nofile 40000 neo4j hard nofile 40000 panos soft nofile 40000 panos hard nofile 40000

I add an entry for all three users?root,?neo4j?and?panos, but you actually just need the one that you’ll use when you restart the service. Then edit

sudo nano /etc/pam.d/su

uncomment this line

session required pam_limits.so

and restart your server (your machine not the service). //改完要重啟機器

Now if you do

sudo service neo4j-service restart

the warning should have disappeared.
