CentOS7.1 installation Liberty's environment preparation (1)

First, the basic platform

1. A Windows system with VMware (networked)

2.CentOS 7.1 64bit Mirror

Second, the minimum installation of two CentOS 7.1 virtual machine Controller, COMPUTE1, the requirements are as follows:

Controller: Memory 2G, hard disk 100G, CPU 2 cores ( tick virtualization engine: virtualize Intel vt-x/ept or Amd-v/rvi, or post-creation instance error ), Network card 2 x

Compute1: Memory 4G, hard disk 100G, CPU 2 cores ( tick virtualization engine: virtualize Intel vt-x/ept or Amd-v/rvi, or post-creation instance error ), Network card 2 x

　　System minimized installation, Shutdown FIREWALLD, SELinux:

systemctl Stop firewalld.servicesystemctl disable Firewalld.service sed ' /selinux/s/enforcing/disabled/g ' /etc/sysconfig/0

Third, network card configuration

Network card number and Configuration Reference official website (the official website has drawn the structure chart, can correspond to see); because it is in the virtual machine building, the choice of network card mode here do not do too much to explain, you can view the relevant information

Controller

ENS33:10.0.0.11/24 (NAT)

ENS34: Do external interface, do not configure IP (bridging)

The configuration ens34 is guaranteed as follows:

Vim  /etc/sysconfig/network-scripts/ifcfg-ens34 DEVICE=ens34 TYPE=Ethernet onboot= " Yes " Bootproto="none"

Compute1:

ENS33:10.10.0.31/24 (NAT)

ENS34: Do external interface, do not configure IP (bridging)

The configuration ens34 is guaranteed as follows:

Vim  /etc/sysconfig/network-scripts/ifcfg-ens34 device=ens34 type= Ethernetonboot="Yes  " bootproto="none"         

Iv. Binding the Hosts

Add the following in each node/etc/hosts file:

# Controller

10.0.0.11 Controller # compute1 10.0.0.31 compute1

It is best to restart the system:

Reboot

Five, verify the connectivity of each node

On the controller: Ping the www.baidu.com node separately ip:10.0.0.31 on compute1: Ping www.baidu.com Verify extranet connectivity VI. Initialize the installation system ToolsController

Yum Install

Compute1:

Yum Install net-tools ntpdate vim

Seven, configure each node time synchronization
