    V. Create a virtual machine
    1 virtualization software used: VMware Workstation 10 (see above)
    The specific installation process will not be mapped, and the common Software installation method, the next step is possible. If you need to activate the code, you can search Baidu.
    2 Installing the operating system Centos 7.4
    The installation process is skipped, the installation times are too many, this does not map.
    Note the following points:
  • The maximum disk size, which can be assigned to 20G, is not used all the time, but increases as the storage content increases. Choose to store the virtual disk as a single file
  • Network adapter, there are three modes: Bridge mode, NAT mode, host mode only. NAT is recommended here, no matter where your notebook is used, the network can be connected properly
    Vi. installation of centos7.4
    Note the following points:
  • Choose to minimize the installation, we do the experiment, do not use the graphical interface.
  • Install location, automatically identify the hard disk, select the partition I want to configure.
  • Select Standard Partition, click the + sign in the lower left corner, add mount point with/boot 200, default unit m
  • Continue to add mount point/swap size by memory twice times set, maximum no more than 8G, Unit is also m
  • Finally, all the remaining load capacity is divided into/root partition, if later work, according to the company's specific requirements to allocate disk size.
  • Point to start the installation, the best step is to set the root password. Be as complex as possible. Password more, you can use the software KeePass described above to save.
