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.

3. Change the permissions on the file:

   Code Block
   chmod 664 /etc/systemd/system/snaplogic.service

   This change provides read and write permissions for the owner and group, and read permission for others.
   
   

4. Open the file with a text editor. For example, the using a vim editor:

   Code Block
   vim /etc/systemd/system/snaplogic.service

   
   

5. Add the following text to the file:

   Paste code macro
   [Unit] Description=SnapLogic JVM After=network.target [Service] Type=forking ExecStart=/opt/snaplogic/bin/jcc.sh start ExecReload=/opt/snaplogic/bin/jcc.sh restart ExecStop=/opt/snaplogic/bin/jcc.sh stop [Install] WantedBy=default.target

   
   

6. Save and exit the file.

   Code Block
   systemctl enable snaplogic.service

   The service will start automatically when the host reboots.
