cluster deployment linux super simple

In this article, I'd like to share with you how to linux The deployment of big data cluster under the environment .

List of articles

One . newly added linux System

1. Clone virtual machine

2. Change the system's mac Address

vim /etc/udev/rules.d/70-persistent-net.rules

3. Change network card information

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

4. System restart takes effect

reboot Restart the network card after restart , View the current network card information , hold HWADDR Delete the information in that line and put IPADDR In that line ip Change it to your own definition ip, Save and exit .

The modification is complete , You can view the modified network card information again .ip The operation is successful !

Two .3 Turn off the firewall

The security of Intranet environment is relatively high , Firewall on will affect efficiency , So turn off the firewall The three cloned machines execute the following command (root User to execute )

 # Check the status of the firewall
service iptables status
# Start the firewall service
service iptables start
# Turn off firewall service
service iptables stop
# Shut down the firewall completely
chkconfig iptables off

3、 ... and .3 Three machines shut down selinux

vim /etc/selinux/config modify selinux Configuration file for

Be careful : It doesn't take effect until it's rebooted

Four .3 Machine change host name

vim /etc/sysconfig/network Modify the host name setting in the system configuration file

Be careful : It doesn't take effect until it's rebooted

5、 ... and .3 This machine is for you ip Address alias

vim /etc/hosts The setting is shown in the figure below :

# Take the configuration of three virtual machines of Xiaojun as an example , The alias settings should be as similar as possible , It's easy to use later . hadoop001 hadoop002 hadoop003

6、 ... and .SCP Remote file copy

scp It's a remote file copy command

 Copy files from local computer to hadoop001( Under the root directory of
# Copy files
scp file name hadoop001:/
scp file name
# replica catalog
scp -r Directory name hadoop001:/
scp -r Directory name 

7、 ... and .SSH Remote login

1. Use ssh Password based remote login



ssh ip Address

Remote login to the specified server ( You have to know the right password )

  • Log in to the second machine on the third machine
  • details : The first remote login will ask yes/no, Not in the future

2. Use ssh Password free login based on key ( master )

ssh-keygen + Three carriage returns stay hadoop001,hadoop002,hadoop003 The above commands are executed separately , produce Public key and Private key ssh-copy-id hadoop01 Copy the public key to hadoop1 The above to , And so on … Copy the public key to another virtual machine .

Once the configuration is complete , You can use ssh Password free login to other virtual machines .

Be careful : ① When copying for the first time, you need to enter the password of the specified virtual machine , In addition, when copying the public key of the virtual machine itself , Need to be in /root/.ssh/ Execute operations under the directory . ② Want to see which virtual machines can log in without password , Sure vim /root/.ssh/authorized_keys see .

8、 ... and . summary

The big data cluster deployment process is complicated , For the first time, you still need to practice . Of course , Don't worry about learning big data well , The bacteria are more abundant every day , If you have any questions, please leave a message in the comments section below , Xiaojun will try to help you . That's all for this sharing , If you think it's useful, don't forget to pay attention to it (<ゝω・)*
