Overview
In x86 machines, there are two power management methods: APM (Advanced Power Management) and ACPI (Advanced Configuration and Power Interface). ACPI is a power management standard developed jointly by Intel, Microsoft, and Toshiba, providing a more flexible interface for managing computers and devices, whereas APM is an older power management standard.
Linux supports both APM and ACPI, but these two standards cannot operate simultaneously. By default, Linux runs ACPI. At the same time, Converge Cloud it is recommended to use ACPI power management.
Failure to install ACPI management programs on Linux systems can result in unsuccessful soft shutdowns. This document outlines the steps to check the ACPI installation status and perform the installation.
Installation Instructions
For CoreOS systems, ACPI installation is not required.
Directions
Execute the following command to check if ACPI is installed.
ps -ef|grep -w "acpid"|grep -v "grep"- If the process does not exist, it indicates that ACPI is not installed. Proceed to the next step.
- If the process exists, it indicates that ACPI is installed, and the task is complete.
Based on your operating system type, execute the corresponding command to install ACPI.
On Ubuntu / Debian, execute the following command:
sudo apt-get install acpidFor Redhat / CentOS systems, execute the following command:
yum install acpid
