Install VMware-tools for Centos 6.3

At EXSi there, right click on the server > Guest > install/upgrade VMware tools
after that enter to the server console

# mount /dev/cdrom /mnt
# cd /mnt
# cp VMwareTools-xxx.tar.gz  /root/
# cd  /root
# tar -zxvf VMwareTools-xxx.tar.gz
# cd vmware-tools-distrib
# ./vmware-install.pl

just click enter until the end

if you received error saying to locate the c compiler
just make a yum update kernel and kernel-devel, then re-run the installer again

# yum update kernel
# /sbin/shutdown -r now

# ./vmware-install.pl

squidview

download the latest package from 

http://www.rillion.net/squidview/

# tar -xzvf squidview-0.7x.tar.gz

# cd squidview-0.7x

before this, make sure you have all the package needed

# yum groupinstall "Development tools"

# yum install ncurses-static

proceed to compile and install

# ./configure

# make 

# cp Makefile.old Makefile

# make oldgcc

# make install

Remove squid cache manually

Stop squid using the command /etc/init.d/squid stop

Next Delete cache directory using rm -rf /var/spool/squid

Create new cache directory using mkdir /var/spool/squid

Change ownership to squid user chown squid:squid /var/spool/squid

Create cache again using the command squid -z

Finally start Squid using the command /etc/init.d/squid start

Clon Hdd for EXSI

Before proceed, first you must enable SSH in EXSi

then you can transfer your own ready make .vmdk by scp or winscp into EXSi

but for myself, i make a standard template in EXSi so i can easily deploy other server in future.

create a new VM but skip the hdd creation 

SSH into EXSi and use this command

# vmkfstools -i <input.vmdk> <output.vmdk>

then edit the VM, add hdd into it but click
use an existing virtual disk and select the newly cron disk

usually the location of the vm is at 

/vmfs/volumes/<random.number>/

so you need to identify out the location

if you re-cron back to the same EXSi server, there might be network problem with the newly cron server because the network card MAC will be different. so you need to go to
/etc/udev/rules.d/70-persistent-net.rules to update your MAC address
you just need to exchange the eth0 with the eth1 and eth1 to eth0

EXSI SSH Keygen path

The SSH keygen folder in EXSi was located in /.ssh/
You can scp the public key from other server and cat id_rsa.pub » /.ssh/authorized_keys
