1.Preliminary preparation
1. Virtual machine VMware
2. Remote connection tools and transmission tools
3. Centos image files, jdk compressed files and Hadoop3.1.3 compressed files
2. Template virtual machine environment preparation
1. Create a new virtual machine

3. If there is no screenshot in step 3, just go to the next step.
4. Step 4
5. Step 5
6. The number of processors and the number of cores are generally two numbers multiplied by four, which cannot be greater than the memory value of your computer
