[Tutorial] How-to install VMTools on CentOS 6

Here is a quick tutorial on how to get VMware Tools up and running on a CentOS 6 Linux machine.  Although the instructions are shown with the GUI, we’ll use terminal so the guide works with both gui and non-gui based installs.

  1. Mount the VM tools installer to your VM
    Install-Upgrade VMware Tools
  2. Open up Terminal
    CentOS6 - Terminal
  3. Execute the following command (this will create a mount point for our CD drive)
    1. mkdir /cdrom
      CentOS6 - VMware Tools - New Mount Point
  4. Execute the following command (this will map the CD drive to our cdrom mount point)
    1. mount /dev/cdrom /cdrom
      CentOS6 - VMware Tools - Map Mount Point cdrom
  5. Execute the following command to move to your temporary files folder
    1. cd /tmp
      CentOS6 - VMware Tools - Temporary Files
  6. Execute the following command to extract the VMware Tools tarball
    1. tar -xvf /cdrom/VMwareTools (tab to autofill the rest of the package)
      CentOS6 - VMware Tools - Extract VMware Tools
  7. Execute the following command to run the VMware Tools installer
    1.  ./vmware-tools-distrib/vmware-install.pl
      CentOS6 - VMware Tools - Install VMware Tools
  8. Press Enter/Return through each of the questions, using their defaults
    CentOS6 - VMware Tools - Install Default Values
    CentOS6 - VMware Tools - Install Default Values Continued
    CentOS6 - VMware Tools - Install Default Values Continued Continued
  9. Verify VMtools is running by looking at the client status in vSphere
    CentOS6 - VMware Tools - vSphere Status

The installation of VMware Tools 9.0.5 build-1137270 for Linux completed
successfully. You can decide to remove this software from your system at any
time by invoking the following command: “/usr/bin/vmware-uninstall-tools.pl”.

CentOS VMware Tools Permission Error

Solution: You need to extract the files from the tarball when installing the guest tools via the tar command rather than the build in Archive Manager installed with the OS.

  1. Mount the VMware Tools to the VM
  2. Copy the VMware Tools tarball to the desktop of the Linux OS
    Copy VMwareTools
  3. Execute the following command to extract the tar’s contents
    1. tar -zxvf VMwareTools-9.0.5-1137270.tar.gz
  4. Change directories to the vmware-tools-distrib that was just extracted from the tarball and execute the following commands to begin the installation
    1. cd vmware-tools-distrib
    2. ./vmware-install.pl
      vmware-install.pl

Setting Static IP in Linux

To setup a static IP in ubuntu, edit your networking settings file.

Here is an example of how to do it:

Open /etc/network/interfaces:

Use these configurations:


auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.0.10
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1

DHCP Address Configuration:


auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

Then restart the service: /etc/init.d/networking restart (Make sure you are running with admin privileges when restarting 🙂 )

Errors From Package Manager in Ubuntu 11.10

Getting the following message from Package Manager in Ubuntu 11.10?

Requires installation of untrusted packages
The action would require the installation of packages from not authenticated sources.

And when you click on the Details dropdown it shows all of the packages that need to downloaded?

Run the following commands:

cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get update

These commands will save a backup of the old lists and then create a new lists folder.
