 > **Note:**
 >
 > - For Oracle Enterprise Linux, TiDB supports the Red Hat Compatible Kernel (RHCK) and does not support the Unbreakable Enterprise Kernel provided by Oracle Enterprise Linux.
-> - A large number of TiDB tests have been run on the CentOS 7.3 system, and in our community there are a lot of best practices in which TiDB is deployed on the Linux operating system. Therefore, it is recommended to deploy TiDB on CentOS 7.3 or later.
-> - The support for the Linux operating systems above includes the deployment and operation in physical servers as well as in major virtualized environments like VMware, KVM and XEN.
-> - Red Hat Enterprise Linux 8.0, CentOS 8 Stream, and Oracle Enterprise Linux 8.0 are not supported yet as the testing of these platforms is in progress.
-> - CentOS 8 Linux is not supported because its upstream support ended on December 31, 2021.
+> - According to [CentOS Linux EOL](https://www.centos.org/centos-linux-eol/), the upstream support for CentOS Linux 8 ended on December 31, 2021. CentOS Stream 8 continues to be supported by the CentOS organization.
 > - Support for Ubuntu 16.04 will be removed in future versions of TiDB. Upgrading to Ubuntu 18.04 or later is strongly recommended.

-Other Linux OS versions such as Debian Linux and Fedora Linux might work but are not officially supported.
+> - If you are using the 32-bit version of an operating system listed in the preceding table, TiDB **is not guaranteed** to be compilable, buildable or deployable on the 32-bit operating system and the corresponding CPU architecture, or TiDB does not actively adapt to the 32-bit operating system.
