Article Introduction：The 502BadGateway error is a common HTTP error code that indicates a communication problem between the website server requested by the client and the server acting as a gateway. When users visit a web page, their requests go through a gateway server, which is responsible for forwarding the requests to the final target server. However, if the gateway server cannot connect to the target server, or the response received from the target server is invalid, a 502BadGateway error will occur. In this article we will

Article Introduction：Want to assemble a server computer to play games? The main difference in playing games on the server is the graphics card and memory. The CPU and hard disk of the server machine are very high configuration. It is not recommended to use a server host to play games. It is not cost-effective. Is it good to assemble a personal computer with a server CPU? This is not recommended. 1. Although the performance of the server CPU is very strong, it is not suitable for playing games in home scenarios. 2. Because the server CPU is mainly designed to run complex computing tasks, its optimization focus is not on single-thread performance, but on multi-core concurrent processing. 3. Compared with the CPU of a home computer, its clock frequency is lower and its cache capacity is relatively smaller, which will cause its performance in single-threaded applications to be inferior to the CPU of a home computer. 4. Additionally, server CPUs typically

Article Introduction：Nginx is a high-performance open source web server and reverse proxy server with lightweight, scalable and high-concurrency processing capabilities. It is widely used to build reliable and efficient web applications and services. Forward proxy is a proxy server application mode that acts as a middleman for the client to help the client communicate with the target server. For example, when a client cannot access certain websites directly, access can be achieved through a forward proxy. In this case, the client sends a request to the proxy server, and the proxy server forwards the request to the target server. Ultimately, it is assumed that there is a network environment within the company, and employees need to access external Internet resources through the proxy server. In this case, the proxy server acts as a forward proxy and receives
