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-Web-Portal-CentOS7-64bit-1.0.9.0.zip

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

http://s3download.teamdrive.net/HostServer/TD-Web-Portal-CentOS7-64bit-1.0.9.0.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-Web-Portal-CentOS7-64bit-1.0.9.0.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-Web-Portal-CentOS7-64bit.zip.asc
gpg: Signature made Do 27 Aug 2015 12:57:38 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.

Note

An import to VMWare ESXi might fail with the error:

Unsupported hardware family 'virtualbox-2.2'.

In this case use the .ovf file starting with vmx_*.ovf

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

First Boot and Initial Configuration

Log in as the root user with the standard password teamdrive.

To change the default password, type in:

[root@localhost ~]# passwd

and define your own strong password. To change the network device and DNS, type in:

[root@localhost ~]# nmtui

A detailed description for the network setup can be found here http://www.krizna.com/centos/setup-network-centos-7/

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: https://wiki.centos.org/TipsAndTricks/VMWare_Server

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@localhost ~]# 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 correctly 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.

Install latest TeamDrive Agent version

Please install the latest TeamDrive Agent docker image. A list of released versions can be found here https://hub.docker.com/r/teamdrive/agent/tags/ To update the docker image use the following command and replace the version number with a newer released version (at the time the VM was created it was the agent version 4.3.1.1656):

[root@localhost ~]# docker pull teamdrive/agent:4.3.1.1656-TMDR

Note

If outgoing requests has to use a proxy server, follow the docker documentation https://docs.docker.com/engine/admin/systemd/#http-proxy to set a proxy for docker. Restart the docker service after adding the proxy configuration.

The agent is a headless version of the standard TeamDrive client. A docker container will be started for each user using the Web Portal (as described in chapter Introduction to the TeamDrive Web Portal).

Changing the Default MySQL Database Passwords

The TeamDrive Web Portal Virtual Appliance uses the following default passwords for the MySQL database. We strongly suggest changing the passwords of the MySQL users root and teamdrive before connecting this system to a public network.

Account type Username Password (default) New Password
MySQL Database Server root teamdrive  
MySQL Database Server teamdrive teamdrive  

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@localhost ~]# mysqladmin -u root -pteamdrive password
Warning: Using a password on the command line interface can be insecure.
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@localhost ~]# 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 change some configuration files using that password as outlined in the following chapters Creating TeamDrive MySQL User and Databases.

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@localhost]# firewall-cmd

An instructions how to configure the firewall can be found here https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-using-firewalld-on-centos-7

Replacing the self-signed SSL certificates with proper certificates

In order to use SSL without any problems, you will need a properly signed SSL certificate (+ key) and an intermediate certificate (certificate chain) from a trusted authority.

Edit /etc/httpd/conf.d/ssl.conf and enter the absolute location of your files into the appropriate settings:

SSLCertificateFile /path/to/your_domain.crt
SSLCertificateKeyFile /path/to/your_domain.key

Depending on your certificate provider and your security needs, you probably want to set:

SSLCertificateChainFile /path/to/server-chain.crt

or:

SSLCACertificateFile /path/to/gd_bundle.crt

After saving the changes, restart your httpd and watch out for errors:

[root@localhost ~]# service httpd restart

Now you can logout and proceed with the configuration via browser to register the Web Portal as described in Associating the Web Portal with a Provider. For production use please read the following two chapters about the necessary storage.

Mount user data Volume

As described in docker-configuration the user data will be stored outside the docker instances. The VM Image has only a small internal disk with max. 10 GB storage capacity. Please mount a larger additional use data volume in /teamdrive if necessary. The approx. necessary storage per user is 50 MB. The user data will be automatically removed, after ContainerStorageTimeout is reached (see System Settings).

Mount docker devicemapper Volume

Docker itself needs storage for the running container instances. The Web Portal background task will automatically remove stopped instances after the the defined IdleContainerTimeout (see System Settings). The time can be short, because the persistant user data is stored outside the docker instances. It will just take a few more seconds if a new instance for the user must be recreated based on the container image.

The VM image comes with a preconfigured 20 GB LVM storage volume using the docker storage driver devicemapper per direct-lvm access. Docker supports different storage drivers as described here: https://docs.docker.com/engine/userguide/storagedriver/selectadriver/

To get an overview of the used storage, see the docker documentation: https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#/examine-devicemapper-structures-on-the-host

You will also find a description how to extend the direct-lvm storage: https://docs.docker.com/engine/userguide/storagedriver/device-mapper-driver/#/for-a-direct-lvm-mode-configuration
