initial setting for centos6

After installation of centos 6 with minimum setting, I usually change some setting on it.

1.first modify /etc/sysconfig/network-scripts/ifcfg-eth0 to get dhcp address to update packages.
#vi /etc/sysconfig/network-scripts/ifcfg-eth0

change this line from off to yes
ONBOOT = yes

2. restart the network to enable it
#ifdown eth0
#ifup eth0

3.update all packages installed in the system
#yum update

#umont /dev/cdrom
#tar zxvf VMwareTools-8.6.5-621624.tar.gz
#cd vmware-tools-distrib
