How to use the upstream module in Nginx

Introduction to upstream module nginx modules are generally divided into three major categories: handler, filter and upstream. In the previous chapters, readers have already learned about handlers and filters. Using these two types of modules, nginx can easily complete any stand-alone work. The upstream module will enable nginx to transcend the limitations of a single machine and complete the reception, processing and forwarding of network data. The data forwarding function provides nginx with horizontal processing capabilities across a single machine, freeing nginx from the limitation of only providing a single function for terminal nodes, and enabling it to have the functions of splitting, encapsulating, and integrating at the network application level. Data forwarding is nginx's ability to build a network application

How to use Nginx to replace Mogilefs distributed storage

1. Introduction to distributed storage systems With the continuous development of information technology, it brings convenience to us. At the same time, the increasing data magnitude, the increasingly complex connections between information, and the increasing concurrency of data access have an increasing impact on i Problems such as the increasingly higher /o requirements and the increasingly complex data types have become urgent problems that need to be solved as information technology continues to develop rapidly. The emergence of distributed storage systems has solved most of the above problems to a large extent. A distributed storage system stores data dispersedly on multiple independent devices. Traditional network storage systems use centralized storage servers to store all data. The storage server becomes the bottleneck of system performance and the focus of reliability and security, and cannot meet the needs of large-scale storage applications. Distributed storage systems adopt scalable

What is the method for integrating Redis in java SpringBoot project?

Redis is completely open source, complies with the BSD protocol, and is a high-performance key-value database. Redis has the following three characteristics with other key-value cache products: Redis supports data persistence and can save data in memory on disk. , it can be loaded again for use when restarting. Redis not only supports simple key-value type data, but also provides storage of data structures such as list, set, zset, and hash. Redis supports data backup, that is, data backup in master-slave mode. The advantages of Redis are extremely high performance – Redis can read 110,000 times

What are the problems with nodejs cluster deployment?

Node.js is a very popular JavaScript runtime environment that developers can use to develop efficient web applications. As applications become more complex, a single Node.js instance can no longer meet high load demands. In this case, developers must deploy the application to multiple servers, thereby creating a cluster. But like any distributed system, Node.js cluster deployment also faces some problems. Next, we will explore these problems and how to solve them. 1. Cluster
