crashed, so added a backup machine, is what we often say lvs+keepalived, hehe! (schema 6, for example)Now the server has eight units, we added a monitoring machine to do server monitoring and backup, the important data back to the monitoring machine, hey! (schema 7, for example)3. SummarySome friends will say, the site architecture so much knowledge on your side also useless how much ah, I want to say yes, we use the following knowledge of the struct

Today, my colleague asked me what is the use of web service in the system? What is the difference between it and the general direct writing on the client? What are the advantages? It is really interesting to answer this question. Since I have asked this question, it means that there are some preconditions for not reaching an agreement. It is easy to explain the technology itself. Therefore, we should first clarify the background of recommending the us

In 2 b Enterprise Services, cloud computing, mobile Internet, professional cloud platform services, distributed technology for the support platform for the normal operation of key technologies.

purpose of the flow queue data is to determine the data in the table where the data will be keptis insert,update and delete, and each operation generates the corresponding log information. In MySQL, if theThe storage engine that holds the transaction, the amount of this log generation is doubled. And if we go through some mature third-party queue software toThe performance of this queue data processing function will be multiplied.3.

The basic architecture of Linux is summarized by the following two graphs (two graphs are the same, but the focus is slightly different)From the knowledge, Linux is composed of two parts: User space and kernel space. Kernel space and user space are two different states of program execution, which can transfer from user space to kernel space through system call and hardware interrupt.Due to the different ver

pressure on the service side. If the page is a static page, you can cache the page on a CDN, reverse proxy Server, or even on a user's browser. However, when the second kill starts, the user refreshes the page and does not request the application server at all. Solution: Using JS script control, reference a JS file in the page (the file is very small), but the file is not cached. The purpose of this JS is to include the start flag, modify the style, generate the next single page URL and random

In the process of expanding the size of Web websites from small to large, the database access pressure is constantly increasing, and the database architecture needs to be dynamically expanded, the database expansion process consists of the following steps. Each extension can improve the performance of the deployment method in the previous step by an order of magnitude. 1. web applications and databases are deployed on the same server. Generally, small

name. After successful matching, the offset of the file in SD is obtained. The 9-bit offset (512 bytes, one sector) is the position of the file. Fopen returns a handle that corresponds to a data structure. The structure generally includes the start position, length, and current read pointer position of the file. The record start position and length are used to prevent cross-border reading. 6. fread The read operation is performed based on the current read pointer of the handle, and the cu
