bsr installation package is available for Windows and Linux. For Linux, CentOS (RHEL) 6.4 or higher rpm package and Ubuntu 16.04 LTS or higher deb package are distributed. To obtain the installation package, please contact Mantech(dev3@mantech.co.kr)

Notice

If bsr runs together with drbd installed, there is a conflict about system resource usage. If drbd was previously installed on your system, you need to uninstall it.

Windows

Installation

You can easily install it by running the installer for Windows and following the steps in the installation wizard. After installation is complete, you will need to reboot your system.

Information

When the installation is completed successfully, the directory is configured as below.

  • bin
    Contains binary programs that make up the bsr.

  • etc
    Path to the configuration file.

  • jre
    Path to the Java runtime environment for the installation package.

  • bsrservice

    Path to the bsr service binary.

    The bsr service performs initialization to perform replication. If service is interrupted, replication may be interrupted, so take care in controlling the service.

Windows' bsr uses local ports 5678 and 5679 internally to perform TCP loopback communication. To change this default port, you need to change the key value in the following registry path and restart the system.

  • path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\bsr\

  • key: netlink_tcp_port, daemon_tcp_port

Update

If you reinstall a new version of a package while BSR is installed, the update installation is performed automatically.

Re-installing the existing version by deleting it from the program and function of the control panel can be cumbersome since rebooting is required after deletion. It is not recommended to update after deleting from the control panel.

Delete

Deleting bsr can delete the bsr package from Programs and Features in Control Panel. The machine needs to be rebooted after deletion.

Linux

Linux distributes kernel modules and utility packages separately, so each must be installed individually and bsr services must be configured separately.

Secure boot support

bsr signs and distributes kernel module files for secure boot support. And you can use the kernel module only by registering the public signing key distributed with the rpm package on secure boot mode. The public signing key is installed in /etc/pki/mantech/ and register the public key as follows.

#mokutil --import /etc/pki/mantech/bsr_signing_key_pub.der

input password:

input password again:

The password can be freely selected and will be applied after reboot.
