Installing IMSS

Procedure

1. Run the /IMSSPackagePath/imss/install.sh file to start the IMSS installation wizard.
2. Press F12 to continue installation.
3. Press F12 to agree with the license agreement.
4. Select the installation type.
   • Fresh install
   • Append install
     If you select this option, select Child Device and specify the IP address, logon user name and password for the management console of the parent device.

     Note Pay attention to the following: The logon user account that you specified must have full administration rights. If the child and parent devices are not in the same subnet, Append install will fail. In this case, modify the parent configuration file pg_hba.conf in /var/imss/pgdata to allow the child device to connect to the parent device's database.

5. Choose to install a local or remote database.
   • Internal PostgreSQL database: This is the default database used.
   • External PostgreSQL database: If you select this option, provide external database information as required.

   Note To use the external database, do the following: Make sure the account used to install the IMSS admin database has the superuser role. Manually change the maximum number of database connections to 600: vi /var/lib/pgsql/9.6/data/postgresql.conf max_connection = 600 (default 100) restart DB service (service postgresql-9.6 restart OR systemctl restart postgresql) Make sure that IMSS and the external database server use the same timezone and time settings; otherwise, some unexpected issues may happen. Make sure that max_locks_per_transaction in postgresql.conf is set to 256, and then restart the database service.

6. Specify the destination folder to install IMSS.
7. Choose to enable the components of the Sender Filtering Service.
   • Enable Email Reputation
   • Enable IP Profiler
8. Verify that your environment meets all minimum system requirements.
9. Wait until the progress bar shows 100%.
   If a message saying "Installation Complete" appears, the installation is successful.
