1. Log into SnapLogic Manager as an Org admin.
   
   
2. Navigate to the project where you want to create your Groundplex, then do one of the following:
   
   
   • 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:
   
   

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



   • For Ubuntu 14.04 or newer, run the following command: 
     $ sudo dpkg -i <filename>.deb
     
     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/openjdk-11.0.5+10-jre/


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

Changing the Installation Folder

If you want to use the/myopt/myroot instead of the /opt/snaplogic as the installation folder and myuser instead of snapuser, do the following steps:

1. Run the following commands after installing the RPM/DEB package:
   1. $ sudo mv /opt/snaplogic /myopt/myroot
   2. $ sudo chown -R myuser /myopt/myroot
2. Add the following properties in the /etc/sysconfig/jcc file. If this file does not exist, create it.
   1. export SL_USER=myuser
   2. export SL_ROOT=/myopt/myroot
3. Restart the service with the following command: 
   $ sudo /myopt/myroot/bin/jcc.sh restart
4. To make a service using init.d, make the /etc/init.d/snaplex file a symlink to the /myopt/myroot/bin/jcc.sh file.

Uninstalling the SnapLogic RPM from your environment

To uninstall the SnapLogic Linux-based package from your environment:

1. Remove all content from the /etc/snaplogic and /opt/snaplogic folders by running the following commands:
   
   1. $ rpm -qa | grep snaplogic
   2. $ sudo rpm -e snaplogic-sidekick-4.main_9292-1.x86_64
   3. $ sudo rm -rf /opt/snaplogic
   4. $ sudo rm -rf /etc/snaplogic
2. Verify that the packages were deleted from the /etc/snaplogic and /opt/snaplogic folders.

System Limits

Some Linux installations have system ulimit settings that are set to lower values. This low setting can cause errors when running higher Pipeline loads on the Groundplex JCC node, such as, java.lang.OutOfMemoryError: unable to create new native thread.
