How to Install and Configure VMware vSphere Hypervisor 6.0 (ESXi 6.0)

1. Register with and Download VMware vSphere Hypervisor 6.0

Open the following link in your web browser

Click the License and Download Tab


Click Create an Account, to Create an Account and Login to the VMware Download Center. VMware will email you an Activation link which needs to be opened to create the account.

The following page will be displayed when you have successfully logged into the VMware Download Center.


Pay special attention to the FREE License information which is displayed, and record this License Number, this will be required in a later article.

Click the download link for VMware vSphere Hypervisor 6.0 – Binaries ESXi ISO Image to download the software required to install ESXi 6.0 and also download the VMware vSphere Client 6.0. The VMware vSphere Client 6.0 software is the client software that allows us to connect and manage the ESXi 6.0 server, this will be required in a later article.

Either use the Download Manager or Manually Download button (which uses your web browser). The CD ISO is only 301MB so should not take too long to download. We have a very slow internet connection, at approx 350 kB/sec, and it takes us approximately 10 minutes to download.

2. Installing VMware vSphere Hypervisor 6.0 (ESXi 6.0)

Write (Burn) the VMware-VMvisor-Installer-6.0.0-2159203.x86_64.iso downloaded in Step 1, to a blank CDROM, using your favourite CD writing software. We use ISO Recorder ( If you are using remote server utilities, e.g. HP iLo or Dell iDRAC,. you can attach the virtual CDROM drive in the server to the VMware-VMvisor-Installer-6.0.0-2159203.x86_64.iso ISO, so there is no requirement to write a CDROM.

This is a step which is often missed, ensure the BIOS BOOT order is set to BOOT from the CDROM Device or ATAPI device in the server, otherwise the computer will not BOOT from the CDROM.

Power on the Computer, the computer will BOOT from the CDROM, and the following BOOT screen will be displayed


The default option is to BOOT ESXi-6.0.0-2159203-standard Installer after 10 seconds, hit any key will pause the BOOT process.


At the Welcome to the VMware ESXi 6.0.0 Installation screen Hit Enter to Continue the installation.


Press F11 (Function Key 11) to Accept the VMware End User License Agreement (EULA)


The ESXi installer will scan the computer storage controller for available devices to install ESXi.


ESXi can be installed on a USB flash drive, SD card attached to the computer, local SATA, local RAID Array, or Fibre Channel or iSCSI LUN. All these are supported options. As the footprint for ESXi is very small only 1GB is required for the ESXi OS installation.

We have written an EE Article here on How to Backup an ESXi installation on an USB Flash Drive or SD card, for security or redundancy. After you have completed the ESXi 5.1 installation, shutdown the server, remove the USB flash drive or SD card, and duplicate it using our EE Article.

When prompted select a disk to install ESXi on, in the following example, we have two disks connected to this computer, a single 1GB disk, and a 120GB disk. We are going to use the small disk for the OS. (this simulates the USB flash drive!). The larger 120GB disk will be used later for the storage of virtual machines.


When prompted, select the keyboard layout and hit Enter to continue. The default keyboard layout is US Default.


When prompted enter a root password, confirm the password and hit Enter to continue


The following will be displayed


When prompted Confirm the Installation on the selected disk and press F11 (Install)
– Function Key 11
All data will be erase, as the disk will be repartitioned.


The Progress Bar will confirm installation progress.



The installation only takes approximately 5-10 minutes, depending upon speed of storage. When the installation has completed the following screen will be displayed.


Remove the CDROM installation disk before rebooting. Hit Enter to Reboot. After hitting Enter the follow screen will be displayed and the computer will reboot.


ESXi 6.0 will operate in evaluation mode for 60 days. This is the same mode as a FULLY LICENSED ESXi 6.0 server. If you wish to evaluate all the bells and whistles that ESXi 6.0 has to offer, do not register your FREE license. for 60 days, this will allow you to evaluate ESXi 6.0 server fully. On day 59/60, Apply your FREE license to continue using the product, or you will not be able to power on any virtual machines.

3. Configuring VMware vSphere Hypervisor 6.0 (ESXi 6.0)
The following screen is displayed when VMware ESXi 6.0 first boots1



The server is fully booted when it displays the following screen


The default server configuration is to use DHCP, if you do not have a DHCP server issuing IP Addresses on your network you will need to assign an IP Address. We recommend you use a static IP Address for your ESXi Host Server.

Press F2 to Customize System, you will be prompted to enter the root username and password.


Select Configure Management Network to change Network Parameters.
Select IPv4 Configuration


Set the Static IPv4 address and network configuration, Subnet Mask and Default Gateway, it’s important to set the correct Default Gateway, as this will be used later. Hit Enter to confirm and save the configuration.


Select DNS Configuration, enter the correct DNS information for your network, and enter a hostname for your server. Hit Enter to save the configuration.


Select Custom DNS Suffixes
Enter your DNS suffix (the domain name for your network). Make sure you have created a DNS A Record in your DNS, so that this server can be resolved correctly through forward and reverse lookups.

Hit Enter to save your configuration.

Press Escape, the following screen will appear, select Y(es) to apply changes.


Press Escape to Logout and return to the console screen.

You will notice on the console screen, the server now has a hostname configured, and correct static IP Address.


Congratulations you have successfully installed and configured VMware vSphere Hypervisor 6.0.

In the next article in the series, we will connect and continue to configure the VMware vSphere Hypervisor 6.0.

Installing and Configuring DHCP role on Windows Server 2012

Installing DHCP role via new Server Manager

Ensure the computer has at least one static IP address assigned before starting the role installation.

Launch the Add Role Wizard from Server Manager.
Select DHCP server role and go through the steps needed for installation.

The last page of the wizard (which comes up after the role has been installed), provides a link – “Complete DHCP configuration”.

This provides some tasks that need to be performed to enable the DHCP server role to work properly after role installation.


Launch the DHCP post-install wizard and complete the steps required.

Creation of DHCP security groups (DHCP Administrators and DHCP Users). For these security groups to be effective, the DHCP server service needs to be restarted. This will need to be performed separately by the administrator.


Authorization of DHCP server in Active Directory (only in case of a domain-joint setup). In a domain joined environment, only after the DHCP server is authorized, it will start serving the DHCP client requests. Authorization of DHCP server can only be performed by a domain user that has permissions to create objects in the Net services container in Active Directory. See how to delegate permissions to do this in active directory.


Figure 3: DHCP Post-Install configuration wizard – Authorization Page


In case completing of the post-install step is missed after role installation, the administrator will continue to see a notification on the action pane and also a link on the DHCP role tile on the main Server Manager page suggesting that some configuration is required. That link would go away only after completion of the post-install task.5

The configuration of DHCP server parameters such as scope, options etc. are no longer available in the new Server Manager. The administrator can now launch DHCP MMC either via Server manager (as shown below), or via the DHCP MMC application in the Start Menu, or writing dhcpmgmt.msc on the command prompt. The administrator can now create scopes, set option values so as to be able to lease out IP addresses and provide option values to clients.


Installing via PowerShell

To install the DHCP server role via PowerShell, one needs to run the following command:
Command: Add-WindowsFeature -IncludeManagementTools dhcp
Note the extra switch (IncludeManagementTools) which is now needed, in contrast to Windows 7. Without this switch, just the DHCP server role would be installed. The DHCP server RSAT tools which includes DHCP MMC, netsh context and the new DHCP PowerShell cmdlets, is not installed by default, unless you give the above flag.

After the role is installed, there are a few other steps that the administrator needs to perform so that the server can work correctly and lease out addresses. This the post-install configuration as performed by the above mentioned post-install wizard. The administrator can either launch the Server Manager and complete the DHCP post-installation task from there (as this is UI-only task) or run the below set of commands which are an equivalent of above.
Creating DHCP security groups

Creating DHCP security groups

Command:netsh dhcp add securitygroups

You will need to restart the DHCP service for these groups to become active.
Command: Restart-service dhcpserver
Authorizing the DHCP server in Active Directory (only needed for a domain-joined setup)
Command: Add-DhcpServerInDC <hostname of the DHCP server> <IP address of the DHCP server>
Now the administrator can launch DHCP MMC either via Server manager, or via the DHCP MMC application from the start menu, or by writing dhcpmgmt.msc on the command prompt. The administrator can now also create scopes, set option values so as to be able to lease out IP addresses and provide option values to clients using DHCP MMC or the new DHCP PowerShell.
If the administrator has completed the post-install configuration using PowerShell, Server Manager may still raise a flag (alert) for its completion using the post-install configuration wizard. This alert can be suppressed by notifying the Server Manager that the post-install configuration has been completed. This can be done by the below command:

Command: Set-ItemProperty –Path registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ServerManager\Roles\12 –Name ConfigurationState –Value 2.

How To Install and Configure Bacula Server on CentOS 7

Bacula is an open source network backup solution that allows you create backups and perform data recovery of your computer systems. It is very flexible and robust, which makes it, while slightly cumbersome to configure, suitable for backups in many situations. A backup system is an important component in most server infrastructures, as recovering from data loss is often a critical part of disaster recovery plans.

Getting Started

The first thing to do after the installation is complete is update the CentOS using:

yum update

This goes through the update which takes a couple of minutes depending on how fast the network is.  You may be prompted to enter a “Y” at various stages of this process.
Installing Nano Text Editor

The next thing to do is install nano text editor so I can easily edit files.  I  find it much easier to use than vi so I prefer using nano.  To install this, I use:

yum -y install nano

Installing wget

Install wget because you will need it later in the installation process.

yum -y install wget

Installing Webmin on CentOS 7

After nano is installed, you need to create a new file called webmin.repo and save it in /etc/yum.repos.d/.  To do this, you can type:

nano /etc/yum.repos.d/webmin.repo

This opens a blank file where you can type in (or copy and paste):

name=Webmin Distribution Neutral

Once it’s pasted (by right clicking), hit Control+X and then Y then Enter to save the file.

Now, install Webmin GPG key using this command:

rpm --import

Now lets check for any updates by typing:

yum check-update

Now it’s time to install Webmin and we do that by typing in:

yum -y install webmin


After a short period of time, Webmin will be installed and it’s time to set it to start automatically by typing the following lines:

chkconfig webmin on
service webmin start

Webmin is now installed and running but we need to allow port 10000 through the firewall so we can access it from another computer.  In order to do this, type the following command:

firewall-cmd --add-port=10000/tcp

If you want to make this rule permanent, you can also type in this which will add it to the rules:

firewall-cmd --permanent --add-port=10000/tcp

If you plan on running Webmin on a different port, you can skip adding 10000 as a permanent rule and set it later with the port of your choice.

Now you should be able to access Webmin using the IP address you used to set up the server when you installed it by going to the browser and typing: (where is the IP of your server)


Installing Bacula 7 on CentOS 7

Now that I have Webmin installed and running, it’s time to install Bacula.

The first thing that you need to do is install epel.  To do this, go find the latest release for CentOS 7 and right click on it to copy the link:

Once you have the link copied, type in wget and paste the link…  it should look like


This will download the RPM and now you will need to install it by typing in the following:

yum -y install epel-release-7-5.noarch.rpm

NOTE: the latest version may be different than shown above so be sure to change it if that is the case.

After the installation of the EPEL, Go ahead and do another update by typing in:

yum update

Now we need to create a file in the /etc/yum.repos.d/ directory like we did with Webmin above.  To to that, we will use nano again and type in the following:

nano /etc/yum.repos.d/epel-bacula7.repo

Now you will need to copy and paste the following into the file we just created:

name=Bacula backports from rawhide
name=Bacula backports from rawhide - Source

Now hit Control + X to exit and hit Y and then Enter to save the new file.

Once you have saved the file, verify that Bacula 7 shows up on the list by typing the following and hitting enter:

yum list bacula*


If you don’t see Bacula 7, verify that you did the steps above correctly.
Now we are ready to Install MariaDB and Bacula

Next you will install MariaDB and all of the Bacula files.  To do that, type in the following:

yum -y install mariadb mariadb-server bacula-director-mysql bacula-console
yum -y install bacula-client bacula-storage-mysql mysql-server mysql-devel

Once everything installs (takes about a minute or two), you will need to start the MariaDB database server by typing in:

systemctl start mariadb.service
chkconfig mariadb on

Next you need to run through the secure installation process for MariaDB which will allow you to set the root password, remove test users etc.  The prompts are easy to follow and everything should be Yes.


The default root password is blank to just hit enter and set a new root password.  This isn’t the password you will use for Bacula, it’s the root mysql password.

After you have completed this step, you will want to go to Webmin which you installed earlier so you can set up the database and a Bacula user for the database.

If you look under Servers, you will probably not see MySql Database Server because you just installed it.  You will need to go to Refresh Modules at the bottom of the menu and click it.  Now you should see MySql Database Server in the list.  Click it and you will be asked to enter the username and password for the database.  This will be root and the password you just entered when setting up the database.

Now you will need to add a bacula database so click Create a New Database.

Type in bacula as your database name for your bacula database and leave the rest of the fields default.  Note, the name must be bacula!


Now you will need to create a bacula user for your database.  To do this, go to User Permissions and Add User to add the user.  Be sure to set the Hosts to localhost and don’t worry about setting permissions.  Click Create.
Now you will click on Database Permissions and add all permissions except Grant for the user you created to the bacula database.  Once again, be sure to have the hosts set as localhost.


Now that your database is created and the user is setup, you will need to create the tables.  You can do this by going back to your SSH terminal and typing (note: add the username you created):

/usr/libexec/bacula/make_mysql_tables -u usernameyoucreated -p

Enter the password you used for the user.


Now we need to tell Bacula to use Mysql as the libary.  To do this, lets first stop the services by typing in:

systemctl stop bacula-dir
systemctl stop bacula-fd
systemctl stop bacula-sd

Now lets set Bacula to use the Mysql library:

su -c 'alternatives --config'

This should show you the following:
There are 3 programs which provide ‘’.

Selection    Command
1           /usr/lib64/
2           /usr/lib64/
*+  3           /usr/lib64/

Hit 1 and press enter to select MySql.

Now lets start the services back by using the following commands:

systemctl start bacula-dir

systemctl start bacula-fd

systemctl start bacula-sd

Now you should be able to go to Webmin and look under System and you will need to click on Bacula Backup System.  Don’t worry if it gives you an error.  This is because you haven’t set up the config yet.  You will need click on Module Configuration and set it up to use MySql and enter the login information you created previously for your Bacula user.


Click Save and you should be able to access the Bacula page where you can set up your Bacula System.


Getting Everything Working

Now that you have that part working, you still can not start any of the daemons yet since they are not set up.  You will have to go into each file and modify them so that they will communicate with each other.

If you try to start Bacula, you may receive the following message:

The Bacula console command /sbin/bconsole could not communicate with the Bacula director. Make sure the password in /etc/bacula/bconsole.conf is correct.

You can either use the File Manager within Webmin or connect to your server using sftp and look in the /etc/bacula directory and you will find the following files you need to edit.  I just drag them back to my desktop and edit them in a text editor.


There are a lot of passwords and IP addresses that need to be changed in there files so pay attention to and @@PASSWORD@@ areas and change them accordingly.

Be sure to catch the bottom of the bacula-dir.conf file and change the catalog database password to the one you assigned when you created the database user.

Also, look for localhost and change this to your local IP address on your backup server.  You don’t need to do this on the clients since you will be setting those up later on.  In fact, you can delete most of the test clients that are in the default if you wish.  I will post a guide on setting up all the configuration files later on.
Firewall Ports

In order to allow clients and consoles to talk to your Bacula server, you need to open ports 9101, 9102 and 9103.  The following command in your SSH console with open these ports.

firewall-cmd --add-port=9101/tcp
firewall-cmd  --permanent --add-port=9101/tcp
firewall-cmd --add-port=9102/tcp
firewall-cmd  --permanent --add-port=9102/tcp
firewall-cmd --add-port=9103/tcp
firewall-cmd  --permanent --add-port=9103/tcp

Now you should be able to start Bacula and see all of the Daemons are showing UP.

Installing Bacula-Web

Bacula-Web uses Apache to serve up the pages so you will need to install Apache and get it running using the following:

yum -y install httpd
chkconfig httpd on
service httpd start

Configure Apache to start at boot:

systemctl start httpd.service
systemctl enable httpd.service

Next you need to add MySql support to Apache by entering the following:

yum -y install php php-gd php-gettext php-mysql php-pdo

Install other common modules needed…

yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel

In order for Apache to get past the firewall, you will need to open the ports by using the following:

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

Now you need to get the web files.  Go to the Bacula-Web website and download the latest version.

Save and unpack the archive to your desktop or another location.  We will need to modify the config file before uploading to the server.

Open the Application/Config directory and rename config.php.sample to config.php and then open it in a text editor.

Look for the MySql area and change the settings to match your server.  Be sure to uncomment the config settings be removing the “//” in front of the $config settings.  You probably just need to edit the password at this point.

//MySQL bacula catalog
$config[0]['label'] = 'Backup Server';
$config[0]['host'] = 'localhost';
$config[0]['login'] = 'bacula';
$config[0]['password'] = 'verystrongpassword';
$config[0]['db_name'] = 'bacula';
$config[0]['db_type'] = 'mysql';
$config[0]['db_port'] = '3306';

After you have saved the config file, you need to upload the files to your server under the /var/www/ directory.  You can SFTP to your server using FileZilla and the IP of your server.   If this server is only serving as a backup server, you can upload the files into the root HTML directory, otherwise you can put the files in whatever directory you wish.   Go ahead and upload the files now.


Now you will need to modify the php.ini file so it has the correct time zone for your system.  Since you already have the FTP up, browse to /etc/php.ini and copy if over to your desktop and them open it in a text editor.  Do a search for “date.timezone” which should be around line 878.  You can find the different time zones available by going to:


Make the change and save the file then re-upload it to the server.

Now you need to go into SELINUX and change the settings to PERMISSIVE.  In order to do this, exit the config file for SELINUX:

nano /etc/selinux/config

Change if from enforcing to permissive and hit Control + X then Y then Enter to exit and save.


Type reboot

After the system comes back online, you should be able to use your IP address to access Bacula-Web!
