A: In RHEL and CentOS, I first came into contact with RHEL. I learned from RHEL. the first company used RHEL, and now this company uses CentOS, it is really difficult to find out the differences between them.
1) RHEL is an operating system developed and maintained by a professional team, while CentOS is maintained by the CentOS community team.
2) RHEL can provide technical support and software function upgrade services for customers. professional technical engineers can help you. without CentOS, you can use it freely, but you need to solve the problem by yourself. no one will help you. Of course, if you do not pay for RHEL, people will not help you.
3) CentOS is based on RHEL, including Oracle Enterprise Linux, and many other Linux systems are based on RHEL. Therefore, CentOS and Oracle Enterprise Linux may be different from RHEL. There will also be some situations.
4) the hardware of the manufacturer is tested based on the RHEL linux version. for example, the Think Server we purchased earlier does not have a NIC driver. I called to ask if it was based on the RHEL test, I don't know if CentOS can drive people. You need to test it yourself.

A: In fact, RHEL/CentOS are based on Red Hat. There is also a mainstream camp based on Debian like Ubuntu and Linux Mint. if it is different, there are some different mechanisms, for example: package management mechanism. The debian series uses dpkg, while the Red Hat series uses rpm and yum. permission mechanism, and so on. It is different from other versions. Because each release has some differences, not the same series has a larger difference. For example, some commands may have different configuration files.
