In the last few articles, I talked about the virtual system installation 、LINUX System installation and hadoop Run the server settings and other content, wrote a detailed operation tutorial , What this article shares is hadoop Download and install steps for .

Before that, it's necessary to make a simple explanation : All the content shared is based on personal experience , Some people may say that it is different from what he has done . This is probably the same distribution you use hadoop It's different . I'm downloading a big quick search DKhadoop Distribution version , Standard version of three nodes , Personal research or learning hadoop Three nodes are enough .DKhadoop The three node distribution, I remember, should be free to download now , I asked them about the difference between the free version and the paid version , There is no difference between the free version and the paid version in the background function , All permissions are open to the free version .

Share this article hadoop The installation steps are still DKhadoop For example .DKhadoop It's really easy to install . I was a sophomore in May 、 A few junior students chatting hadoop Things about , They make complaints about the installation and installation of the environment . There is no such thing as a one-time installation , It's a fact that it's broken down . I asked them to download DKHadoop Try the installation , As for whether or not I tried later, I don't know . Let's get to the point , Look at the whole installation process and you'll see hadoop Installation can be as simple as before !
