RHEL: 3. Install Graphlytic

Install Graphlytic

Install Graphlytic as service

After this installation Graphlytic will start automatically after operating system is started. Neo4j is required by Graphlytic so there is also need to install Neo4j as a service (see RHEL: 2. Install Neo4j)

Graphlytic application will be started by user 'graphlytic'. Create this user with home directory (home directory is used by neo4j drivers to store known hosts <home>/.neo4j/known_hosts):

$ sudo useradd -m graphlytic
$ sudo usermod -L graphlytic

Copy Graphlytic installation file "graphlytic-<version>.tar.gz" into /tmp/.

Create directory structure:

$ sudo mkdir -p /usr/share/graphlytic /var/log/graphlytic
$ sudo chown -R graphlytic:graphlytic /usr/share/graphlytic /var/log/graphlytic

Copy installation file and unpack it:

$ sudo su graphlytic
graphlytic:$ cp /tmp/graphlytic-<version>.tar.gz /usr/share/graphlytic
graphlytic:$ cd /usr/share/graphlytic
graphlytic:$ tar zxvf graphlytic-<version>.tar.gz

Graphlytic's configuration is stored in the "conf/graphlytic.conf" file.

To configure Graphlytic run this command:

graphlytic:$ vi /usr/share/graphlytic/conf/graphlytic.conf

Default configuration is as follows:

# where Graphlytic stores its data
main.dataDir=../data/
# where Graphlytic stores log files
main.logDir=/var/log/graphlytic/
# where Graphlytic stores external widgets
main.widgetsDir=../widgets/
# where Graphlytic stores external icons
main.iconsDir=../icons/
 
# login page logo title
site.logo.title=Graphlytic
 
#HSQLDB schema name
hsql.schema=GRAPHLYTIC
 
# Bolt connection to Neo4j
neo4j.connector.bolt=bolt://localhost:7687
neo4j.connector.username=neo4j
neo4j.connector.password=admin
#encryption of the connection to DB. Neo4j 4 requires ssl to be explicitly enabled and configured. It does not accept default self-signed Neo4j 3 certificates.
neo4j.connector.encrypted=false

To change the starting script's configuration run this command (this is an optional step):

graphlytic:$ chmod a+x /usr/share/graphlytic/bin/graphlyticd
graphlytic:$ vi /usr/share/graphlytic/bin/graphlyticd

Edit the starting script file to use HTTP or HTTPS (or both) for connecting to the Graphlytic web application. This is an optional step (default config is HTTP and HTTPS both enabled).

#!/bin/sh
 
# use this script with created service
 
# disable or enable HTTP/HTTPS. To disable comment od remove line
#HTTP_PORT=8080
HTTPS_PORT=8443

Copy init script and enable service:

$ sudo cp /usr/share/graphlytic/bin/graphlytic-init-rhel /etc/init.d/graphlytic
$ sudo chmod a+x /etc/init.d/graphlytic
$ sudo systemctl enable graphlytic.service

Check if service was enabled:

$ sudo find /etc/rc?.d/ -name "*graphlytic*"
 
expected result:
/etc/rc2.d/S99graphlytic
/etc/rc3.d/S99graphlytic
/etc/rc4.d/S99graphlytic
/etc/rc5.d/S99graphlytic
