Install VMware-tools

It might be challenging to install VMware-tools if we don't know what exactly we are doing.
You need to read all the instructions that is provided by VMware workstation or Virtual Center or ESX server.
For now, I am going to give the instruction for Linux systems.
After installing Linux as Virtual Machine on the top of VMware workstation/ESX Server or VSphere (whatever), you will see that VMware-tools is not installed.

Steps to be followed:

1) Choose "Install VMware tools" from VM menu

2) You will recognize some change on "cd-rom" icon located at Left corner of VM. It just like someone has inserted the CD of VMware tools in your VM.

3) Now you need to mount the CD-ROM so that you can access the contents.
#mount /dev/cdrom /mnt/cdrom
If you are lucky, above command will work without any issue. If not you might have to specify some mount options like
# mount -o ro /dev/cdrom /mnt/cdrom
(which mean mount as read-only option)
Some systems requires you to specify the file-systems type. FYI, CD-ROM uses iso9660 file-system
# mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom

4)After this, go to /mnt/cdrom directory. You will find VMware-toools over there. You can install from RPM or TAR file. It all depends on you, however I recommend tar file.

# cd /mnt/cdrom
# rpm -ivh [VMware-tools......rpm]

or
# cd /mnt/cdrom
#tar -xvzf [VMware-tools.......tar] /root/vmware
(this will un-archive the "tar" file under /root/vmware directory
# cd /root/vmware
#./vmware-install.pl
