Chapter 3. Operating system requirements
- Red Hat Enterprise Linux (RHEL) 7.2, 7.3, or 7.4
- CentOS 7.2, 7.3, or 7.4
Kernel versions 3.10.0-327.22.2.el7.x86_64 and higher are tested. For best performance, keep the kernel up-to-date.
The RHEL/CentOS 7 distributions provide a variety of server configurations. Control Center is tested on operating system platforms that are installed and configured with standard options. Docker and Control Center are tested on the Minimal Install configuration with the NFS and Network Time Protocol (NTP) packages installed.
Control Center relies on the system clock to synchronize its actions. The installation procedures include steps to add the NTP daemon to all hosts. By default, the NTP daemon synchronizes the system clock by communicating with standard time servers available on the internet. Use the default configuration or configure the daemon to use a time server in your environment.
