What are the visualization tools for Redis?
1. Command line 1.1, iredis Use iredis, use | to pass redis through the pipe and use other shell tools, such as jq/fx/rg/sort/uniq/cut/sed/awk, etc. to process. It can also auto-complete, highlight, and have many functions. Official website address: https://iredis.io/2, Visualization Tool 2.1, Desktop Client Version 2.1.1, RedisDesktopManager This tool should be the most widely used visualization tool now. It has been around for a long time. It went through several iterations. Cross-platform support. It used to be free, but now it's a paid tool. The trial can last for half a month.

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

thinkphp does business process
In the Internet era, the optimization and digitization of business processes has become a required course for enterprises, and thinkphp, as an efficient and concise PHP development framework, can quickly help developers realize the digital transformation of business processes. This article will introduce the specific application of thinkphp in business processes. 1. Introduction to business processes Business processes refer to a series of work processes involved within an enterprise or across organizations. Through graphical analysis, design, and implementation, we can ultimately optimize the process, improve work efficiency, and reduce costs and risks. The specific process includes:

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. Phalcon, Phalcon is the fastest PHP framework. 3.Sym

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.

Mysql large website technical architecture core case analysis
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. The greatest value of a software architect does not lie in how many advanced technologies he has mastered, but in the ability to divide a large system into N low-coupling sub-modules. These sub-modules include

What are the core principles of mysql large-scale website technical architecture?
1. Evolution of large-scale website architecture A. Large-scale website software systems are characterized by high concurrency, large traffic; high availability; massive data; widely distributed users, complex network conditions; poor security environment; rapid changes in requirements, frequent releases; progressive development; B .Evolution and development process of large-scale website architecture 1. Initial stage: one server, LNMP 2. Separation of application services and data services: application server (CPU); database server (fast disk retrieval and data caching); file server (large hard disk); 3 .Use cache to improve website performance: local cache cached on the application server (fast access, limited by application server memory, limited data volume), remote distributed cache (use a cluster to deploy a server with large memory as a dedicated cache server)

How to enable mysql query slow log
1. What is the MySQL query slow log? The MySQL query slow log is a performance analysis tool that comes with MySQL and is used to record query requests that exceed a specified time threshold. The query slow log records various performance indicators of each query, including required time, number of executions, execution plan, etc. Through these metrics, developers can identify which queries need to be optimized for efficiency and take appropriate action. Generally, MySQL query slow log is not enabled by default and must be manually configured to enable it. In the MySQL configuration file (my.cnf), you can set the parameters of the configuration file to enable the query slow log. The following is an example configuration for querying the slow log: slow_query_log=1slow_
