After completing the above steps, we can also add some configuration information in the/ETC/MY.CNF configuration file to reduce the MARIADB resource requirements, please refer to the link given at the end of the article.

will have a lot of time waiting for hard disk IO, seriously affecting the response speed of the server.
(2) Other VPS on the same server will be affected (unless the same hard drive is used).
5,* Note that you distinguish between "use swap" and "swap":
(1) Using swap, means that the data is stored in swap, is a fixed state, does not occupy hard disk IO.
The following figure, although the system occupies 13M of swap, but no swap swap.
(2) Swap is th
Anyone who opens an SSH account using OpenSSH knows that opening an SSH account takes up two session processes and occupies about 8 MB of memory. This makes VPs with low memory hard to run, the number of accounts that can be opened is greatly reduced.
I found some materials and methods on the Internet. After testing, I found that the use of lightweight dropbear to replace OpenSSH memory is significantly re
problems: When the physical memory is greater than 1G, the kernel linear address space is less than the actual physical memory capacity, how the kernel to achieve greater than 1G of memory management? In this case, you need to mention the kernel space-to-memory management method. On the one hand, in order to improve the management efficiency of kernel space to memory, on the other hand, in order to simplify the kernel space memory management method, the kernel uses the linear mapping method to
Compared to the previous years of low-priced fighting, in 2015, the eyes of domestic handset manufacturers focused on the middle and high-end market.After 5 years of rapid development, China's mobile phone market has entered the smart phone stock replacement period, the stock users tend to more high-end product iteration; Therefore, for domestic handset manufactu
This article mainly introduces the comprehensive comparison of the two vrouters, as well as the working principle, performance factors, and decision indicators of the vrouters.
Low-end routers and high-end routers are still commonly used. So I have studied the comprehensive comparison between the two vrouters. Here I will share with you, hoping to help you. Recen
This article describes in detail how low-end and high-end routers think about network security, as well as the basic principles of routers. I believe this article will help you.
Low-end routers and high-end routers are similar in
Recently, some netizens asked in the Forum: "low-end routers and high-end routers are similar in usage. Why is the price so far different ?" In fact, this question is very good, and many friends who are not familiar with the product and technology will basically have similar questions-"Why is this router so expensive with the same functions, another one is so che
At present, the routing technology is developing rapidly, and the performance of routers is getting higher and higher. "low-end routers and high-end routers are similar in usage. Why is the price so far apart ?"
In fact, this question is very good, and many friends who are not familiar with the product and technology will basically have similar questions-"Why is

The so-called "big-end mode" refers to the low data (that is, the number of lower weights) stored in the high memory address , and the high level of data, stored in the low memory address , Such a storage pattern is somewhat similar to processing data as a string order: The add
Huawei three-tier devices can be IP and Mac binding, but a large number of that is sacrificing the cost of equipment performance, and sometimes attacks and network failures are easy to cause greater trouble. Moreover, the price of three-tier equipment is not all enterprises can buy at will.
How to do Mac binding on two-tier low-end products to prevent the impact of ARP on the network.
Step One: Enter port
Low-end switches are quite common, So I studied how to correctly select low-end switches. Here I will share with you, hoping to be useful to you. Currently, low-end switches in the Chinese market cover many brands from foreign net
The instance explains the common steps for low-end vswitch MAC binding. Today, the topic of low-end vswitch MAC binding is about the detailed steps for low-end vswitch MAC binding. You can easily complete the settings, there is no

It is also the low address (s_b1) of the memory corresponding to the low byte (such as 0xco ).
This is also observed on my machine, which is consistent with the byte order of X86. Generally, the network programming transmission order is the network byte order, that is, the large-end
