    How to optimize and configure the number of MySQL connections
    What is the number of MySQL connections? The number of MySQL connections refers to the maximum number of client connections allowed on the MySQL server. When the client establishes a connection with the MySQL server, the connection will occupy some server resources, including memory, CPU, network bandwidth, etc. If there are too many connections, the server will not be able to handle all client requests, resulting in system crashes or serious performance issues. In order to avoid this situation from happening, we need to optimize and control the number of MySQL connections. How to optimize the number of MySQL connections? Optimizing the number of MySQL connections requires starting from the following two aspects: hardware and software. First, we need to increase the hardware resources of the server, including memory, CPU, hard disk capacity, network bandwidth, etc., which will

  • How to implement Redis persistence
    How to implement Redis persistence
    Redis is an advanced key-value database. It is similar to memcached, but data can be persisted and supports a wide range of data types. There are strings, linked lists, sets and sorted sets. It supports calculating the union, intersection and complement (difference) of sets on the server side, and also supports a variety of sorting functions. Redis supports two persistence mechanisms: RDB and AOF. Persistence can avoid data loss caused by abnormal process exit or downtime. The previous persistence file can be used to achieve data recovery during the next restart. RDB persistence RDB persistence is persisted by creating snapshots (compressed binary files) to save the full amount of data at a certain point in time. RDB persistent

    thinkphp6 cache time setting
    ThinkPHP6 is an efficient, simple and flexible PHP backend development framework. During the development process, in order to improve website performance and user experience, we often need to use caching technology. However, once the cache validity period expires, it will affect the performance of the website. Therefore, setting the cache time is very important. The ThinkPHP6 framework provides a variety of cache drivers, including file cache, Redis cache, Memcached cache, etc. This article will mainly introduce how to set the cache time of file cache and Redis cache. 1.

    Example analysis of Redis vulnerability exploitation
    1. Introduction Redis-related vulnerabilities have existed for a long time, and there are still scenarios that can be exploited. This time, we will summarize and reproduce the redis-related vulnerability exploits so that we can quickly establish exploitation ideas when encountering them in the future. 2. Introduction to redis Redis is a key-value storage system. Similar to Memcached, it supports relatively more stored value types, including string (string), list (linked list), set (**), zset (sortedset--ordered **) and hash (hash type). Redis largely compensates for the shortcomings of key/value storage such as memcached. In some cases, it can play a role in relational databases.

    What is the difference between redis and memcached in PHP
    1. Supported data types: memcached only supports key-value types, redis also supports list, set, hash, that is, redis supports more abundant data types 2. Storage data security: after memcached hangs up, the data cannot be recovered, redis supports data For persistence, the data in the memory can be saved to the disk, and can be loaded again for use when restarting. The main difference: redis supports persistence. What are the PHP frameworks: 1. Laravel, Laravel is a free and open source PHP application framework. 2.

    What is the Redis data structure?
    Redis is a high-performance key-value database. The emergence of redis has largely compensated for the shortcomings of keyvalue storage such as memcached, and can play a very good supplementary role to relational databases in some situations. 1. String The string type is the most basic data structure of redis. First of all, the key is the string type, and several other structures are built on the basis of the string type, so the string type can be used for the other four data structures. Learn the basics of Dharma. The string type can actually be a string (simple string, complex string (xml, json), number (integer, floating point number), binary (image, audio, video)), but the maximum cannot exceed 512M. make

    How to use PHP7.0 to implement a distributed storage system?
    With the development of the Internet, the explosive growth of data volume has made traditional storage methods unable to meet demand, and distributed storage systems have emerged as the times require. Distributed storage systems improve data security, reliability and availability by dispersing data to different nodes for storage. In the process of implementing a distributed storage system, PHP7.0, as a popular server-side scripting language, can help us easily implement the functions of the project. What is a distributed storage system? A distributed storage system refers to storing data on different devices.

    7. On-demand: Extensible architecture of the website Extensibility: refers to the ability to continuously expand or improve system functions with minimal impact on the existing system. It is the opening and closing principle at the system architecture design level. The architecture design takes into account future functional expansion. When new functions are added to the system, there is no need to modify the structure and code of the existing system. Scalability: refers to the system's ability to enhance (reduce) its own computing and processing capabilities by increasing (decreasing) the scale of its own resources. A. Building a scalable website architecture 1.
