Introduction#

Memtester is a small tool for detecting the real allocatable memory of a VPS, suitable for detecting overselling situations. The allocatable memory detected by this program refers to the maximum amount of memory that can be occupied by the user when in use.

Usage#

Run the following command:

# CentOS/RHEL system
yum install wget -y
yum groupinstall "Development Tools" -y
