Open Ports on the ScienceLogic Database Server Appliance

Name Description Protocol Port
HTTP Interface Optional. Can be used if the Database Server also serves as an Administration Portal. TCP 80
HTTPS Secure Interface Optional. Can be used if the Database Server also serves as an Administration Portal. TCP 443
Database Web Admin Optional. Administrative Web Interface (PHPMyAdmin) from browser session on user workstation. TCP 8008
MariaDB

Communication from Administration Portal.

Communication from HA-secondary and DR to HA primary.

  If you are using HA/DR, you must keep this port open. This port is required for communication between the HA-secondary and DR to the HA-primary appliance. If this port is blocked, the em7service on these databases will fail and could lead to issues such as DR backup not working or inability to license the appliances.

TCP 7706
SSH Optional. Can be manually closed. For ssh sessions from user workstation. TCP
