In the previous articles, I wrote detailed tutorials on virtual system installation, LINUX system installation and hadoop running server settings. This article shares the download and installation steps of hadoop.

Before this, it is necessary to make a simple explanation: all the content shared is based on personal experience, and some people may say that it is different from what he has done. This may be caused by a different distribution version of hadoop that everyone uses. I was downloading a big fast search DKhadoop distribution, the standard version of three nodes, personal research or learning hadoop three nodes is perfectly adequate. I remember that the distribution version of DKhadoop three nodes should also be free and open to download now. I asked them specifically about whether there was any difference between the free version and the paid version before. There is no difference between the free version and the paid version in the background function. All permissions are open to the free version.

This article shares hadoop installation steps are still DKhadoop as an example. Installation of DKhadoop can be said to be really simple. In May, I talked to several sophomore and junior students about hadoop. Their complaints focused on the installation of the environment. There was no such thing as a one-time successful installation, but it was a fact that it crashed. I asked them to download the DKHadoop installation and try it, but I don't know if they tried it later. Let's get down to business. After reading the entire installation steps, you will find that hadoop installation can be so simple!

I. Download the DKH installation package

Installation package uploaded in the network disk, need to install the package friends can leave a message for! The download step is omitted.

II. DKH installation steps

1. Login: After successful startup, access IP, login default username and password: Username:admin

Password:123456

2. Terms of Use:

3. Cluster specified host (please do not refresh the page during installation):

4. Cluster installation (installation of DKM components): There are three installation methods: "basic installation","complete installation" and "custom installation".

(1) Basic installation:

(2) Complete installation: DKM integrates relatively complete components of big data development environment.

(3) Custom installation: Users can select components to install and assign roles to components according to their own needs.

(4) Click "Continue" to view the assigned roles of each machine.

5. Start installing components: I will use the "basic installation" method to carry out the example. Other methods are similar. Select "Next" and the progress bar as shown below will appear.

6. Click "Complete Installation" to go to the DKM monitoring interface (ip:8998). First, you need to log in, username: admin , password: admin.

7. Click Login to enter the cluster monitoring interface, as shown below:

Entering the cluster monitoring interface means that the installation is successful. The content of the cluster monitoring interface will be left behind to share with you. This part of the content of the best and write a few articles in front of the combination to see easier to understand! Previous articles:
