First, the concept of the Gateway: Gateway, also known as the Inter-Network connector, protocol converter. The gateway realizes network interconnection above the network layer, is the most complex network interconnection device, only for two high-level protocol different network interconnection. Gateways can be used for both WAN interconnection and LAN interconne

it?Let's start with some of the things that this architecture needs to do and the shortcomings that exist: first, It destroys the service stateless Feature. In order to ensure the security of the external services, we need to implement the access control of the service, and the Open service control mechanism will run through and pollute the entire open services business logic, This will bring the most direct problem is that the service cluster of the rest API stateless Features. From t

this time, Nginx cannot transfer the PHP file to PHP-FPM processing, so the CPU will be reduced to very low (not to handle PHP, not to execute SQL), and the load will rise to very high (close and open children, nginx wait php-fpm), the network card traffic is also reduced to very low ( Nginx cannot generate data transfer to client)Solving the problem is simple, increase the number of children, and set max_requests to 0 or a larger value, restart PHP-FPMThe implication of Nginx 504

This section describes the application instances used to configure the vswitch gateway. When you search for the keyword set for the vswitch gateway, you need to learn the detailed steps for setting the vswitch gateway. Therefore, this article should be able to meet the needs of most netizens. When talking about how to set a vswitch, the hardware router is familia

Recently in the work, the need to do Excel import function, because of the Excel data is more, and our server program needs to check the content of the data, will call a lot of external service interface, so no suspense import Excel interface call more than a minute, and error: 504 Gateway Timeout Here are two ways to solve this problem: 1. Optimize business code An interface called for more than a minute, there must be a place to optimize, to see w

MicroServices architecture, usually a business system will have a lot of microservices, such as: OrderService, Productservice, UserService ..., in order to make the invocation more simple, usually in the front end of these services to encapsulate a layer, similar to the following:In front of this layer is commonly known as "Gateway layer", its existence significance is that the "1 to N" problem into the "1 to 1" problem, while the request to the real

Some websites running on Nginx sometimes appear as "502 Bad Gateway" errors, some times even frequently. The following is a small compilation of some of the Nginx 502 error troubleshooting Methods for reference: The reason for the Nginx 502 error is more due to a problem with the backend server in Agent mode. These errors are generally not nginx itself problem, must look for the reason from the back end! But nginx all these mistakes in their own body

The current communication methods are inseparable from the IP network. To combine the two, you must use the gateway. Now let's talk about the knowledge of Cisco's unified voice gateway. Which models are available in these products, and what are the differences between these models? Cisco Unified Communication Voice Gateway Cisco 1700, 2600XM, 2800, 3700 and 3800,

rather than databases. But at first the idea was inspired by Shenli's article, "Micro-SOA: Principles of Service design and practices", which was thought of in conjunction with other ideas. The idea is only a utility model at present, the specific use of the effect also needs further verification, but only for the small and medium-sized development team, in the early implementation of the micro-service can completely replace the API gateway. is a com

Nginx is characterized by the handling of static is very strong, Apache is the characteristic of processing dynamic is very stable, the combination of the two is Lnmpa,nginx processing front end, Apache processing the backend, so the processing of static will soon, processing dynamics will be very stable. When I think the installation is finished, and behold, when the site was updated 504 Gateway time-out; At first, I thought it was accidental, after

CenOS gateway ProblemsA problem occurred when we used PacketiX VPN. After a long time, I did not solve the problem, so I found out the problem by looking for their technical staff to completely simulate our network environment. It is representative and I will share it with you.The network environment is as follows:The headquarters of the company uses the hardware firewall of Juniper. The intranet gateway is

Virus Detection mechanism: a virus is a piece of code, and the final form is a file. Any data streams that are transmitted on the Internet must be composed of files to be detected by the anti-virus scanning engine. When browsing the Web page, we actually get a lot of html files, gif icons, and script files through the http protocol, and the files will eventually arrive at the user's place. To implement http virus filtering, the gateway anti-virus prod
