Installing CentOS 6.5 into VMware Fusion 6.0.2

Posted on Monday Jan 12, 2015 at 11:45PM in Technology

What are the good points of virtual machines?

I'm working to move my personal financial system which is running on a physical machine to virtual machine because its simplicity of maintenance and portability. currently I'm running the system on tower form PC, but it makes annoying noise, and it consumes power much, so I'm going to make the system virtual, and move it to my old MacBook or something.

Backup of virtual machines are so easy because it exists as regular files in the physical machine, and it can be automated easily thanks to OS X's TimeMachine and VMware Fusion's snapshot. and I can easily move its machine running on in case I need to do it. when I want to do some heavy calculation, I can easily copy the whole of the virtual machine to another high-performance environment anytime while running it on low power-consuming machine regularly.

Installation

VMware Fusion 6.0.2 supplies "easy installation" function for CentOS 6.5 (not for 7.0). which answers annoying questions instead of me during installation process. all I need to answer were username and password to use. then, VMware will getting almost all of my work done contains installation of VMware Tools. several minutes after, you'll see GUI login prompt. for my purpose GUI is unnecessary but I don't want to do these annoying work by myself so I just followed this way.

I made some changes before installation begins such as following:

Increase HDD size to 384GB (There's no need to reserve that actual size in the host machine. actual size increases with actual use in the virtual machine. Increasing of size is impossible when snapshots available, but it's possible after deleting all of snapshots)
Increase CPU number to 2
Increate amount of memory to 2GB
Set network interface to physical (I want to login via ssh from my LAN)
Enable VNC daemon

Partitioning that VMware did automatically:

[kyle@localhost ~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3       374G  2.6G  353G   1% /
tmpfs           935M  228K  935M   1% /dev/shm
/dev/sda1       291M   39M  238M  14% /boot

After installation TODOs:

Software update (System -> Administration -> Software Update)

Add user to sudoers

su -
visudo

then insert following:

kyle    ALL=(ALL)       NOPASSWD: ALL

Change timezone to sync the clock

sudo cp -p  /usr/share/zoneinfo/Japan /etc/localtime

Put your ssh public key to ~/.ssh/authorized_keys (make sure to set the permission of .ssh directory to 700, authorized_keys file to 600. if permission wasn't set correctly, password prompt will be appeared)

I would write more about following procedure such as installation of middleware or database.
