Virtual Appliance Installation and Configuration

Download and Verify the Virtual Appliance Image

A .zip Archive containing the virtual appliance’s disk image and VM configuration can be obtained from the following URL:

http://s3download.teamdrive.net/HostServer/TD-Host-Server-CentOS6-64bit-3.5.1.0.zip

Download the .zip archive and the corresponding SHA1 checksum file:

http://s3download.teamdrive.net/HostServer/TD-Host-Server-CentOS6-64bit-3.5.1.0.zip.sha1

You should verify the SHA1 checksum to ensure that the zip archive is intact.

You can use the sha1sum command line utility on Linux to verify the integrity of the downloaded file.

For guidance on how to verify this checksum on other platforms, see the following articles:

For additional safety, we recommend to verify the cryptographic signature of the zip archive as well.

You need to have a working GnuPG installation in order to verify this signature. The installation and configuration of GnuPG is out of the scope of this document — see the documentation at https://gnupg.org/ for details.

The public TeamDrive Build GPG key can be downloaded from here:

Import the key into your keyring and double check it matches the fingerprint provided below:

$ gpg --fingerprint support@teamdrive.net
pub   2048R/9A34C453 2014-07-01
      Key fingerprint = 8F9A 1F36 931D BEFA 693B  9881 ED06 27A9 9A34 C453
uid                  TeamDrive Systems (RPM Build Key) <support@teamdrive.net>
sub   2048R/6048C568 2014-07-01

Each official release is signed with this TeamDrive GPG key. The signature can be obtained from the following URL:

http://s3download.teamdrive.net/HostServer/TD-Host-Server-CentOS6-64bit-3.5.1.0.zip.asc

To verify the signature on a Linux operating system, the .zip and corresponding .asc file should be located in the same directory. Now run the following command:

$ gpg --verify TD-Host-Server-CentOS6-64bit-3.5.1.0.zip.asc
gpg: Signature made Mo 18 Mai 2015 10:34:09 CEST using RSA key ID 9A34C453
gpg: Good signature from "TeamDrive Systems (RPM Build Key) <support@teamdrive.net>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 8F9A 1F36 931D BEFA 693B  9881 ED06 27A9 9A34 C453

The procedure on other platforms may vary, please consult the GnuPG documentation for details on how to accomplish this task.

Import the Virtual Appliance

After you have confirmed the integrity and authenticity, unzip the zip archive.

The archive contains four files, a virtual disk image (.vmdk), two virtual machine description files (.ovf) and a manifest file (.mf), containing the file names and SHA1 checksums.

Import the virtual machine image according to the documentation of your virtualization technology and adjust the VM parameters (e.g. number of virtual CPUs, RAM) based on your requirements, if necessary.

Start up the virtual machine and observe the virtual machine’s console output.

First Boot and Initial Configuration

When you boot up the VM image for the first time, the Operating System will perform a number of initial configuration steps, to customize the virtual machine for your environment. For more details on these individual steps, please refer to the Red Hat Enterprise Linux 6 Installation Guide.

The first screen will prompt you to select your keyboard layout. Use the cursor keys to select the appropriate layout and press Tab to select the OK button. Press Space or Enter to proceed.

After loading the appropriate keymap, you will now be prompted to enter the password for the root user account. Choose a strong password here — the root user has full administrative privileges on a Linux system. The password won’t be printed on the screen for security reasons, therefore you need to enter it twice to avoid typos.

Next, you are required to configure the network device and DNS.

../_images/TD-Host-Server-VMInstall-NetConfig.png

Press Enter to enter the device configuration screen. Select the network device which is usually named eth0. The hardware description (e.g. AMD PCnet32 or Ethernet) depends on the virtual network card that your virtual machine has been configured with. Press Enter to get to the device configuration details.

The network configuration screen allows you to specify the IP address and other network-related settings. Adjust these to your local environment, keeping the requirements outlined in chapter Network Requirements in mind. the Tab key to move between elements. Select the Ok button and press Space or Enter to apply your changes. In the device selection screen, select the Save button to save the device configuration.

Note

Note that you should not use dynamic IP addresses (DHCP) for the TeamDrive Host Server. The TeamDrive Service depends on static IP addresses and requires a resolvable fully qualified domain name.

Next, select the DNS configuration screen from the network configuration and adjust the DNS settings to match your environment. Enter your Host Server’s host name (e.g. hostserver.yourdomain.com) in the Hostname field and add your DNS server’s IP address(es). Select the Ok button to apply the DNS changes.

Select the Save&Quit button to proceed with the installation.

Note

A cloned CentOS image in a VMWare environment might exhibit problems updating the network interface. If you are observing issues when configuring the network interface, please follow these instructions: http://alexcline.net/2011/11/15/reconfiguring-network-interfaces-in-centosrhel-systems-cloned-with-vcenter/

The next screen allows you to modify the local user authentication configuration. Unless you have specific requirements for your local environment, it’s safe to keep the proposed defaults and proceed with the installation by selecting the Next button.

../_images/TD-Host-Server-VMInstall-AuthConfig.png

The following screen will ask you to select which services should be started at system bootup time. Adjust these based on your requirements and local policies. Also make sure that the MySQL database (service mysqld) is enabled. Select the Ok button to proceed.

Note

Do not enable the Apache HTTP Server (httpd) yet — this should only be done after the Host Server has been configured correctly.

The system will now proceed with the bootup process until you reach the login prompt.

Log in as the root user, providing the login password you defined during the initial installation.

Updating the Installed Software Packages

As a first step, we strongly advise to perform an update of the installed software packages. New security issues or software bugs might have been discovered and fixed since the time the Virtual Appliance has been built.

This can be done using the yum package management tool. As a requirement, the Virtual Appliance needs to be connected to the network and needs to be able to establish outgoing HTTP connections to the remote RPM package repositories. To initiate the update process, enter the following command:

[root@hostserver ~]# yum update -y

yum will first gather the list of installed packages and will then determine, if updates are available. If any updates need to be installed, the affected RPM packages will now be downloaded from the remote repositories and installed.

If the yum update installed any updated packages, consider performing a reboot before you proceed, to ensure that the updates are activated.

Note

Performing a regular update of all installed packages is an essential part of keeping your system secure. You should schedule a regular maintenance window to apply updates using yum update (and perform a reboot, to ensure that the system still boots up fine after these updates). Failing to keep up to date with security fixes may result in your system being vulnerable to certain remote exploits or attacks, which can compromise your system’s security and integrity.

Changing default passwords

The TeamDrive Host Server Virtual Appliance uses the following default passwords for user accounts of the different software components. The following list shows the accounts in question and their passwords.

Note

We strongly suggest changing the passwords of the OS and MySQL root user accounts before connecting this system to a public network.

Default accounts and passwords
Account type Username Password (default) New Password
MySQL Database Server root teamdrive  
MySQL Database Server teamdrive teamdrive  
Admin Console HostAdmin (defined during setup)  

Changing the MySQL Database Passwords

To change the passwords for the MySQL root and teamdrive user, please use the following commands. First change the password for the root user:

[root@hostserver ~] mysqladmin -u root -pteamdrive password
New password: <new password>
Confirm new password: <new password>

Next, log into the MySQL database as the root user (using the new password) and change the password for the user teamdrive:

[root@hostserver ~]# mysql -u root -p
Enter password: <new password>

[...]

mysql> SET PASSWORD FOR 'teamdrive'@'localhost' = PASSWORD('<new password>');
Query OK, 0 rows affected (0.00 sec)

mysql> quit
Bye

Note

Take note of the new MySQL password for the teamdrive user, as you will need to update that password in a configuration file as outlined the following chapter.

Updating the MySQL Database Connection Information

The default Host Server Appliance installation assumes a MySQL database instance running on localhost that can be accessed using the user teamdrive and password teamdrive. If you changed the password of the teamdrive the following change need to be performed.

The Host Server Apache modules mod_pspace and mod_yvva as well as the yvvad daemon that performs the td-hostserver background tasks need to be able to communicate with the MySQL management database of the Host Server. To change the MySQL login credentials, edit the file /etc/td-hostserver.my.cnf. The password for the teamdrive MySQL user in the [p1db] option group must match the one you defined earlier:

[p1db]
database=pspace
user=teamdrive
password=<password>
host=127.0.0.1

Firewall Configuration

The iptables-based OS firewall on the TeamDrive Host Server Virtual Appliance has been configured to only allow access to the following services:

  • SSH (TCP Port 22)
  • Secure WWW (HTTPS, TCP Port 443)
  • WWW (HTTP, TCP Port 80)

If necessary, you can change the firewall configuration using the following utility:

[root@hostserver install]# system-config-firewall-tui

Follow the instructions to configure the firewall and to enable additional protections based on your local requirements or security policies. More complex firewall settings need to be performed by editing the firewall rules in file /etc/sysconfig/iptables directly.

SELinux Configuration

Please note that the TeamDrive Host Server currently can not be run when SELinux is enabled. Therefore SELinux has been disabled by setting SELINUX=disabled in file /etc/selinux/config. It is important to leave it disabled, otherwise the correct functionality of the Host Server can not be ensured.
