Configuring the Content Manager

1. Log on to the server that you have designated as the Content Manager in your environment.
2. Open the /app/clarity/dmanager/etc/mesh.conf file in a text editor (it might not have previously existed).
3. Add the following line:
   manager_type=mega_manager
4. Save the /app/clarity/dmanager/etc/mesh.conf file.

5. Link the PostgreSQL files from the corresponding directories using the following commands, depending on the RHEL version you are using:

   RHEL version	Directory	Command
   If you are installing on RHEL 9 or RHEL 8 with PostgreSQL server 15	/usr/pgsql-15/bin	ln -snf /usr/pgsql-15/bin/* /usr/bin/
   If you are installing RHEL 8 or RHEL 7 with PostgreSQL server 11.x	/usr/pgsql-11/bin	ln -snf /usr/pgsql-11/bin/* /usr/bin/
   If you are installing on RHEL 8 or RHEL 7 with PostgreSQL server 12.4	/usr/pgsql-12/bin	ln -snf /usr/pgsql-12/bin/* /usr/bin/
   If you are installing RHEL 7 with RH-PostgreSQL 12	/opt/rh/rh-postgresql12/root/usr	ln -s /opt/rh/rh-postgresql12/root/usr/lib64/libpq.so.rh-postgresql12-5 /usr/lib64/ ln -s /opt/rh/rh-postgresql12/root/usr/lib64/libpq.so.rh-postgresql12-5 /usr/lib64/libpq.so.5 ln -snf /opt/rh/rh-postgresql12/root/usr/bin/* /usr/bin/

6. Run the configure_megamesh script:
7. /app/clarity/manager_scripts/bin/configure_megamesh

8. When prompted, enter passwords for the Multi-Manager users (megamesh and megamesh_config) in postgres.

   Note

   These are new passwords that will be used again when you add the Satellite Manager or Managers to the mesh.

9. Open the /app/clarity/dmanager/etc/dmanager.conf file in a text editor.
10. Add the following line:
    megamanager=true
11. Save the /app/clarity/dmanager/etc/dmanager.conf file.
12. Restart the dmanager service:
    service dmanager restart
13. Add an unprivileged Multi-Manager user to the OS:
    useradd -m -r megamesh
14. Restart the Multi-Manager service:
    service megamesh restart

Where to go from here

Use the procedure in Adding-Satellite-Managers-to-the-mesh to create the Multi-Manager mesh.
