Install GCC for RedHatLinux

Suddenly I found that the RedHatLiunux on my own virtual machine does not have the GCC compilation tool. I don't know what to do at a time. You can only download the rpm package. However, I couldn't find one on the Internet. I found it was too large to find one on the Internet. The network speed was very slow. It was estimated that I could not find it for a month. I had to try to use the installation disk and try to install programs that I had not installed before from the disc. However, when the virtual machine is opened, it is discovered that the virtual machine does not boot from the CD, but directly enters the system. I realized it was a problem with bios settings, but I don't know how to suddenly find that the RedHat Liunux on my own virtual machine didn't have the GCC compilation tool.

I realized that it was a problem with bios settings, but I didn't know how to enter the bios. I found bios settings in the vm menu and couldn't find them. Then I searched the internet to find that the bios of the original virtual machine is the same as that of the real machine. Finally, GCC is installed.
