This article describes the procedures for installing an on-premise Snaplex in a Linux environment. An on-premise Snaplex is also known as a Groundplex. This document uses the term Groundplex to distinguish this type of Snaplex (on-premise) from other types, such as a Cloudplex or an eXtremeplex, which is managed by SnapLogic. However, in command syntax and references to the UI, the generic term Snaplex is used.

1. Log into SnapLogic Manager as an Org admin.
   
   
2. Navigate to the project where you want to create your Groundplex, and perform one of the following steps:
   
   
   • Click the Snaplex tab, then click  to display the Snaplex dialog.
     OR
   • Click to display the Assets drop-down list, then select Snaplex; the Snaplex dialog appears.
     
     
     
3. Enter the required information on the Create Snaplex form. Once completed, the Downloads tab on the Snaplex popup appears. The Downloads tab has links to the installer and configuration files.
   
   
4. Download the RPM/DEB and the configuration file onto a Linux machine, with fontconfig and zip as required dependencies:
   
   

   • For CentOS (or Redhat) 6.3 or newer, run the following command:
     $ sudo rpm -i <filename>.rpm to sudo rpm -i <filename>.rpm fontconfig zip



   • For Ubuntu 14.04 or newer, run the following command: 
     $ sudo dpkg -i <filename>.deb fontconfig zip
     
     Where <filename> is the name of the current installer file.
     
     

5. After the software is installed, place the downloaded configuration file in the /opt/snaplogic/etc directory and make sure the file name ends with .slpropz. Change the .slpropz file so that snapuser owns it by running the following commands:

   Code Block
   $ sudo chown snapuser:snapuser /opt/snaplogic/etc/myplex.slpropz $ sudo chmod 600 /opt/snaplogic/etc/myplex.slpropz

   
   

6. To start the Snaplex service, run:
   $ sudo /opt/snaplogic/bin/jcc.sh start


7. To verify the Snaplex has started, visit https://elastic.snaplogic.com/sl/dashboard.html#Health. The newly installed Snaplex node should appear in the list of nodes for the Snaplex.

1. Stop the existing JCC node by running the following command:
   $ sudo /opt/snaplogic/bin/jcc.sh stop
   
   
2. Download the new Snaplex installer and install the Groundplex, running the RPM, DEB, or Docker installers as appropriate.
   • For RPM systems, run the following command:
     $ rpm -U snaplogic-snaplex.rpm
   • For DEB systems, run  the following command:
     $ dpkg -i snaplogic-snaplex.deb
   • For Docker, stop the existing container and start a new container using the latest image.
     
     
3. Add the following entry to the /etc/sysconfig/jcc directory. You must create this directory and file if neither are present. 
   export SL_JAVA_HOME=/opt/snaplogic/pkgs/jdk-11.0.12+7-jre/


4. Start the JCC node by running the following command:
   $ sudo /opt/snaplogic/bin/jcc.sh start.
