Installation of Linux virtual machines (graphic explanation)

The next article will be followed by the Hadoop cluster installation (based on this)

I. Installation preparation

VMWorkstation and linux system images (the following uses CentOS6.5 as an example)

Disable Firewall:

Service iptables stop

Chkconfig iptables off

 

Add a fixed ip Address:

 

Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Modify and add:

HWADDR = 00: 0C: 29: 60: 77: 3D (HWaddr corresponding to the local host)

ONBOOT = yes

BOOTPROTO = none

IPADDR = 192.168.83.small (local IP)

(You can view it using ifconfig)

GATEWAY = 192.168.83.2

DNS1 = 8.8.4.4

DNS2 = 222.85.85.85

Save and restart the network.

Service network restart

Note:(How to synchronize system time after installation)

Time Synchronization may affect the use of hadoop clusters and MapReduce in the future.

If the system time is incorrect after installation, run the following command to synchronize the system time:

Ntpdate cn.pool.ntp.org

The NTP socket is in use, exiting solution appears:

Cd/etc/rc. d/init. d

./Ntpd stop

 

Local ssh Configuration

Go to the. ssh directory/root/. ssh

Delete an existing file

Rm-f *

Ssh-keygen-t rsa

Press enter to the end of the execution
