How to configure Tcp load balancing in Nginx

How to configure Tcp load balancing in Nginx

This article uses Nginx as a proxy server for load balancing. It is just a simple application example and does not involve principles. (The hosts here are limited. Port 8000 of the 42.192.22.128 host is used as the proxy server listening port, and 8181 is the service listening port.) The client accesses the proxy server, and the proxy server distributes the request to the corresponding server. Modify the Nginx configuration file to configure Tcp load balancing (the configuration file is in /usr/local/nginx/conf/nginx.config after Nginx installation, and the Nginx executable program is in the /usr/local/nginx/sbin directory) in nginx. conf configuration file

How to bind nginx reverse proxy secondary domain name

How to bind nginx reverse proxy secondary domain name

1. Application scenarios We often encounter situations where multiple web sites are established on the same server. A common approach is to configure different ports for different sites so that they can be accessed in the form of ip:port. But after all, using IP to access is inconvenient, not vivid, and not easy to remember. Then, we can bind different domain names to each site. (Here we only talk about the public network situation) Even if we only have one domain name, we can set up multiple second-level domain names, which is easy to achieve using nginx. 2. Basic requirements Usually, online tutorials will directly post a piece of code for the configuration file and tell us that this is OK. But I found that many novices cannot succeed like bloggers after looking at the tutorial configuration, so next I

How nginx+iis implements simple load balancing

How nginx+iis implements simple load balancing

1. nginx installation nginx is a lightweight web server/reverse proxy server and email (imap/pop3) proxy server, and is released under a bsd-like protocol. It was developed by Russian programmer igorsysoev and is used by Russia's large portal website and search engine Rambler (Russian: рамблер). Its characteristics are that it occupies less memory and has strong concurrency capabilities. In fact, nginx’s concurrency capabilities do perform better among web servers of the same type. Users of nginx websites in mainland China include: Baidu, Sina, NetEase, Tencent, etc. The latest version of nginx is 1.9.3. The one I downloaded is the window version.

What are the methods for Nginx to implement grayscale publishing?

What are the methods for Nginx to implement grayscale publishing?

Method 1: By adjusting the load balancing weight, load balancing is built on the existing network structure. It provides a cheap, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network performance. Flexibility and availability. Load balancing, whose English name is loadbalance, means to allocate execution to multiple operating units, such as web servers, ftp servers, enterprise key application servers and other mission-critical servers, etc., so as to jointly complete work tasks. The simple configuration is as follows: http{upstreamcluster{ip_hash;#If you do not use a third-party cache management tool in your system, it is recommended to use this method server
