The Linux system provides us with the solution, that is, the Tmpfs file system, TMPFS can use the memory directly, while not enough memory to use the swap partition to store. Also note that TMPFS is not persistent, restart data does not retain, please be sure to note, but we only use it to store cached files, even if the file is lost does not affect the site access, there is no risk. /dev/shm/is a device file that uses the Tmpfs file system (note: Under CentOS and Redhat,/dev/...)

The reason is that the Linux kernel does not have the concept of "Linux container", the container is a user state concept. Docker software engineer Michael Crosby will write some blog posts and dive into Docke ...

Cloudstack is an open-source, highly available and scalable cloud computing platform that supports the management of most mainstream virtual machine managers, such as KVM and XEN. There are two types of storage in Cloudstack: Primary storage provides disk volumes for virtual machine instances, and level two storage provides templates for virtual machine instances to install mirrored files for systems and disk snapshots of virtual machine instances. Both types of storage support network-attached storage (NAS). Figure 0. Cloudstack architecture This article we will be a Linux host ...

In fact, see the official Hadoop document has been able to easily configure the distributed framework to run the environment, but since the write a little bit more, at the same time there are some details to note that the fact that these details will let people grope for half a day. Hadoop can run stand-alone, but also can configure the cluster run, single run will not need to say more, just follow the demo running instructions directly to execute the command. The main point here is to talk about the process of running the cluster configuration. Environment 7 ordinary machines, operating systems are Linux. Memory and CPU will not say, anyway had ...
