Before installing QoreStor, refer to QoreStor installation modesQoreStor installation modesand the QoreStor Interoperability Guide for additional information.

To install QoreStor in Object Direct mode

  1. Copy the QoreStor installation files to the server.
  2. Set execution permission on the installation files using chmod. For example,

    $ chmod a+x qs_inst_7.1.1.162.bin

  3. With elevated privileges (either as root or with the sudo command), run the installation script with the desired parameters, using the below information as a guide. To install QoreStor in object direct mode, use the --object-direct parameter.
  • qs_inst_7.1.1.162.bin -- -f –p <repository_path> -m <metadata_path> --object-direct --mode=<cloud-optimized|standard|large> --accept-eula --install-deps -e <cloud-provider> -t <cloud-container-name> -o <cloud-connection-string>


-f enables firewall configuration
-h, --help displays this help message
-p, --repository_path=<pathname> is the path to the repository storage

-t, --cloud_container_name=<name> container name for object storage
-o, --cloud_connection_string=<password> access key for object-direct storage
--mode=<large |standard |cloud-optimized> selects the type of storage configuration


    • $ sudo ./qs_inst_7.1.1.162.bin
