Iii. System Installation notes

During system installation, you must install the desktop mode. Otherwise, oracle cannot be installed. In addition, do not enable SELinux. oracle does not recommend SELinux, and CentOS Firewall should be temporarily disabled to reduce installation troubles. To prevent garbled characters during Oracle Installation, we recommend that you use English as the system language to install Oracle.

The system commands described in this article are marked as "#", which indicates the root permission, and "$" indicates the oracle permission.
