如何限制一个程序的“物理内存”？

现在想启动mongodb这个数据库以后，这个进程不要占用太多的物理内存。有办法做到吗？

Red Hat Enterprise Linux 6 provides a new kernel feature: control groups, which are called by their shorter name cgroups in this guide. Cgroups allow you to allocate resources—such as CPU time, system memory, network bandwidth, or combinations of these resources—among user-defined groups of tasks (processes) running on a system. You can monitor the cgroups you configure, deny cgroups access to certain resources, and even reconfigure your cgroups dynamically on a running system. The  cgconfig ( control group config) service can be configured to start up at boot time and reestablish your predefined cgroups, thus making them persistent across reboots
