That's all.

Cloning virtual machine on vmware esx using vmware-cmd

Below are the steps:

1. List down all the virtual machines that you have

# /usr/bin/vmware-cmd -l
/vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx
/vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-2/server-2.vmx
/vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-3/server-3.vmx

2. Shutdown the machine that you are going to clone. Let say the machine is server-1

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx stop

3. Use hard stop if you cannot stop it using above command

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx stop hard

4. Make sure the vm is shutdown by viewing the state

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/server-1.vmx getstate

5. Copy the whole directory

# cp /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/server-1/ /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/

6. Once done, rename all the files to new name

# rename server-1 newserver /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/*

7. Change all occurrence of "server-1" to "newserver" in .vmx, .vmdk and .vmxf

# cd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/
# sed -i 's/server-1/newserver/g' {newserver.vmdk,newserver.vmx,newserver.vmxf}

8. Edit newserver.vmx file and remove below lines

ethernet0.generatedAddress = "....."
ethernet0.generatedAddressOffset = "....."
uuid.location = "....."
uuid.bios = "....."

9. Add below line to newserver.vmx

uuid.action = "keep"

10. Register your newly cloned virtual machine. Please use the full path to register as below

# vmware-cmd -s register /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/newserver.vmx

11. Start your new vm after registration.

# /usr/bin/vmware-cmd /vmfs/volumes/47971de9-34657d96-8ac4-001d09068c0c/newserver/newserver.vmx start

vim comment lines

In linux, while editing configuration files, we always used # sign for comments. How do we do it to multiple lines in vi easily?

Steps:

1. Edit the files using vi
$ vi files.conf

2. set line number in vi (for us to easily determine what is the line number that we want to edit)
:se nu

3. replace start of lines with # (for example, put # sign in front of line 2 to line 5). The meaning of below command is for line 2 - 5, subtitute (s) start of line (^) with # sign, and press enter
:2,5s/^/#/
<enter>

4. It is done. Save your file (w) and quit (q)
:wq

yum plugin to remove dependencies

You can remove dependencies using yum-plugin-remove-with-leaves plug-in.

To install:

# yum install yum-plugin-remove-with-leaves

To use:

# yum remove --remove-leaves <package-name>

That's all folks :)

Using markers in vi/vim

This feature is useful if for example we want to delete a few lines or characters but we are too lazy to count the lines or characters to use dd or dw command. We can set up to 26 marker using lowercase a-z as the marker's name. The main usage of marker is to mark any location in file.

How to use (we put 'a' as the marker's name):

ma - mark current cursor position as marker named 'a'
`a (backquote a) - move to character marked as 'a'
'a (quote a) - move to first non blank character (line) containing marker 'a'
`` (backquote backquote) - move to last operated marker or toggles with last cursor position, if no marker is set, cursor moves to beginning of file (BOF)
'' (quote quote) - move to beginning og line (BOL) operated marker or toggles with BOL of last cursor position, if no marker is set, cursor moves to BOF

Example on using marker:

If you want to indent 5 lines starting from current line: majjjjj>'a
If you want to delete five words using marker: mawwwwwmb`ad`b

That's all friends :)
