 ### For CentOS 7
 
+> [!WARNING]
+> CentOS Linux 7 reached the end of life (EOL) on June 30, 2024. You can change the mirror to vault.centos.org to install software.

 The following steps work on CentOS 7. For other CentOS versions, these steps might work but are not guaranteed to work.
 
 1. Run the bash script `README.CentOS.bash` in the `deploy/build` directory of the `cloudberrydb/cloudberrydb` repository. To run this script, password is required. Then, some required dependencies will be automatically downloaded.
