Setup Neo4j Service to run with different service ID
By default when neo4j is installed as an RPM via yum or apt-get, it creates a user
neo4j and group
neo4j and runs as
However it might be required to run Neo4j service as another service id other than
So in this article we will take a look at how to go about configuring Service id to run Neo4j service.
For simplicity lets assume the activity is performed on Redhat Release 7.x
Follow instructions as specified in the Neo4j Operations Manual Documentation to install Neo4j Enterprise. https://neo4j.com/docs/operations-manual/current/installation/linux/rpm/
Once the Neo4j service is installed, a new user and group are created called
When the Neo4j service is started using
sudo systemctl start neo4j, the service is started by user
To setup and start the Neo4j service as a different user we must follow the below outlined steps.
We will use the user
testuser and group
testuser to setup neo4j service.
First step is to edit the
neo4j.service and change the user and group as
testuser so the service can start as that user and group.
sudo vi /usr/lib/systemd/system/neo4j.service
Edit as show below by changing the
[Unit] Description=Neo4j Graph Database After=network-online.target Wants=network-online.target [Service] ExecStart=/home/rohan_kharwar/neo4j-enterprise-3.5.5/bin/neo4j console Restart=on-failure User=testuser Group=testuser Environment="NEO4J_CONF=/home/rohan_kharwar/neo4j-enterprise-3.5.5/conf" "NEO4J_HOME=/home/rohan_kharwar/neo4j-enterprise-3.5.5" LimitNOFILE=60000 TimeoutSec=120 [Install] WantedBy=multi-user.target
Second step is to change the ownership of the below files to
For RPM install:
/etc/neo4j /etc/neo4j/jmx.access /etc/neo4j/jmx.password /etc/neo4j/neo4j.conf /var/lib/neo4j /var/lib/neo4j/data /var/lib/neo4j/data/databases /var/lib/neo4j/import /var/lib/neo4j/plugins /var/log/neo4j /var/run/neo4j
Steps documented as :
$ sudo chown testuser:testuser -R /etc/neo4j $ sudo chown testuser:testuser -R /var/lib/neo4j $ sudo chown testuser:testuser -R /var/log/neo4j $ sudo chown testuser:testuser -R /var/run/neo4j
Once the above steps are completed, the file ownership should be changed to
Then start the neo4j service as:
$ sudo systemctl start neo4j
and this should start as the service user that was setup.
To verify if the neo4j service is started as user
ps -ef | grep -i neo4j
and the output should show
testuser as given below
testuser 3296 1 26 18:00 ? 00:00:19 /usr/bin/java -cp /var/lib/neo4j/plugins:/etc/neo4j:/usr/share/neo4j/lib/*:/var/lib/neo4j/plugins/* -server -XX:+UseG1GC -XX:-OmitStackTraceInFastThrow -XX:+AlwaysPreTouch -XX:+UnlockExperimentalVMOptions -XX:+TrustFinalNonStaticFields -XX:+DisableExplicitGC -Djdk.tls.ephemeralDHKeySize=2048 -Djdk.tls.rejectClientInitiatedRenegotiation=true -Dunsupported.dbms.udc.source=rpm -Dfile.encoding=UTF-8 com.neo4j.server.enterprise.CommercialEntryPoint --home-dir=/var/lib/neo4j --config-dir=/etc/neo4j
