Jenkins is an open source software project, which is a continuous integration tool based on Java development, which is used to monitor continuous repetitive work. It aims to provide an open and easy-to-use software platform and make continuous integration possible. The functions of Jenkins include: 1. Continuous software release
This paper mainly introduces and demonstrates some commands and usage of Redis-related status monitoring and performance tuning: 1. Redis-benchmarkredis benchmark information, redis server performance testing such as: testing redis server performance, native port 6379
The concept of ConfigMap often meets the need to modify the configuration file in the production environment, the traditional modification will not only affect the normal operation of the service, but also the operation steps are very tedious. To solve this problem, the kubernetes project introduced Conf from version 1.2.
one。 Introduction to the concept and principle of Docker Swarm Docker Swarm Swarm was developed in Objective C, and applications written in early versions of Swarm also enabled Objective C to derive from Sw
The stability of CVM is very good. Virtual hosts are the preferred solution for many users to build stations. In this way, many users use one server at the same time, so if one website is disturbed, all other websites will be affected. So the stability of the space will be greatly reduced. But this is not the case when using a CVM.
Supervisor is a set of Linux general process management procedures, the main role is to assist operators to manage the programs deployed on the Linux server; the main functions are as follows: 1: your application starts with the launch of Supervisor. 2:

Nginx dynamic and static separation allows dynamic web pages in dynamic websites to distinguish between immutable resources and frequently changing resources according to certain rules. After the dynamic and static resources are split, we can cache them according to the characteristics of static resources. This is the core idea of website static processing.

RPM is the abbreviation of Red-Hat Package Manager (RPM package Manager). Although the file format name is marked with the logo of RedHat, its original design concept is open, including OpenLinux and S.u.S.E.
First of all, borrow a diagram to show that the relationship between linux applications and kernels is different from bare metal programs. The application development under linux does not directly access the hardware, but the application program calls the driver to access the hardware. This is the system structure of linux. For more information, please see "embedded linux Application Development".
Introduction to PHP PHP, that is, "hypertext preprocessor", is a general open source scripting language. PHP is a scripting language executed on the server side, which is similar to C language and is a commonly used website programming language. According to the requirements of dynamic websites, PHP language, as a language program, its specificity is gradually being used.
