How do I add swap space manually when swap space is not available?The following actions are performed under the root user:First create a partition, using the DD command such asDD If=/dev/zero of=/home/swap bs=1024 count=512000 This creates a partition file such as/home/swap. The size of the file is 512,000 blocks, norm

DigitalOcean has been used for a long time. a process was killed when PHP was compiled a few days ago. After I spoke with others, I found that the memory was exhausted. In fact, it was because the MySQL process at that time consumed a lot of memory, and later felt it was necessary to manually add Swap (Swap partition), so as to avoid the process being K when compiling or something later. About

A swap is an area of high-speed storage devices and an important part of the virtual memory system. Through the swap zone, we are no longer limited to limited physical memory space. Theoretically, we can infinitely expand the virtual memory system to run more programs and conduct more business transactions, make full use of hardware resources. The swap zone uses

use scenes for swap Swap has two main uses 1, when the system needs more memory space than physical memory, the kernel will use less memory inside the memory page swap out to the swap partition, to empty out the physical memory to the current should be used for fast running. 2, some applications started when the appli

Recent memory usage shows a large swap consumption, but there is no command to see directly the size of a process occupying swap. You can only see the total swap and how much.In fact, in the proc under the Process Number command folder is the use of swap, only need to add all the size of the beginning of the

PrefaceThe previous time in using the program to deal with the larger data, found that the original memory of their computer is not enough and often go to die, so think of the use of swap partition to expand the way memory. Now make a brief summary:the concept of swap partitioningThe initial swap partition was when I entered the lab to install the Linux system, a

Swap uses: Swap means the swap partition, which is usually what we call virtual memory, which is a partition that is partitioned from the hard disk. When the physical memory is not available,The kernel releases some long-unused programs in the cache (Buffers/cache) and then temporarily puts them in swap.This means that swap
