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.

To generate and import a self-signed certificate on all the JCC nodes in the Snaplex:

1. Obtain the certificate (.pem) file by using SSH.
   
   

2. Import the file by using the following command in the JCC node:
   

   Paste code macro
   /opt/snaplogic/pkgs/jre1.8.0_45/bin/keytool -import -file <path_to_pem_file_from_step_1> -alias <alias_name_optional> -keystore /opt/snaplogic/pkgs/jre1.8.0_45/lib/security/cacerts -vEnter keystore password: changeit

   
   

   Note
   This example is an excerpt from 1.8.0_45; the directory path might vary based on the Java installation directory.

   
   

3. Restart the JCC node process to confirm the import.
   
   

4. Run the following command to list certificates from the CAcerts file:

   Paste code macro
   /opt/snaplogic/pkgs/jre1.8.0_45/bin/keytool -list --keystore /opt/snaplogic/pkgs/jre1.8.0_45/lib/security/cacerts -v+

   
   

...

1. Log into the Groundplex host as a root or sudo user.
   
   

2. Create the startup service file:
   

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

   
   

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.
   
   

7. Enable the service by running the following command:

   Code Block
   systemctl enable snaplogic.service

   The service will start automatically when the host reboots.
   
   

8. Start the service:

   Code Block
   systemctl start snaplogic.service

   
   

9. To stop the Snaplex as a service, run the following command:
   

   Code Block
   systemctl disable snaplogic.service

   
   

...

1. Login to the Linux machine as root.
   
   

2. Change directories:

   Code Block
   cd /etc/init.d/

   
   

3. Create a softlink to the jcc.sh file: 

   Code Block
   ln -s /opt/snaplogic/bin/jcc.sh snaplex

   
   

4. Add the softlink to chkconfig management:

   Code Block
   chkconfig --add snaplex

   
   

...

1. Log in to the Linux machine as root.
   
   

2. Change directories:

   Code Block
   cd /etc/init.d/

   
   

3. Create a soft-link to the jcc.sh file: 

   Code Block
   ln -s /opt/snaplogic/bin/jcc.sh snaplex

   
   

4. Install the service using update-rc.d. For example: 

   Code Block
   sudo update-rc.d snaplex defaults 98 02

   
   

   Note
   title Troubleshooting if the machine reboot fails
   We recommend that you reboot the machine to verify whether the Snaplex service is restarting automatically on machine reboot. Under some conditions, the symlink resolution might fail when the machine is starting up. In this case, you can change the Snaplex startup script to be a file instead of a symlink. Run the following commands a root user: Code Block rm /etc/init.d/snaplex cp /opt/snaplogic/bin/jcc.sh /etc/init.d/snaplex echo "export SL_ROOT=/opt/snaplogic" >> /etc/sysconfig/jcc On a Debian system, the /etc/sysconfig directory would need to be created if not already present.

   
   

5. To stop the Snaplex as a Service, remove the service from update-rc.d management:
   

   Code Block
   update-rc.d -f snaplex remove
