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 popup.
     OR
   • Click to display the Assets drop-down list, then select Snaplex; the Snaplex popup 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 show up in the list of nodes for the Snaplex.

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

To fix this issue, you need to increase the system limits for the Snapuser user. You can add the following in the /etc/security/limits.conf folder to increase the file and process limits.
