- How to use nginx for load balancing
- Four-layer load balancing vs seven-layer load balancing. It is often said that seven-layer load balancing or four-layer load balancing is actually decided based on the name of the layer of the iso osi network model. nginx uses the http protocol to load the application layer. Balanced operation, so it is called seven-layer load balancing. For example, lvs that performs load balancing operations on the tcp layer is called layer 4 load balancing. Generally speaking, there are the following load balancing classifications: Common software support Common load balancing algorithms Common load balancing algorithms include the following: Load balancing demonstration example: ordinary polling Next, use nginx to demonstrate how to perform ordinary polling. : Prepare in advance to start two services on the two ports 7001/7002 for display.

- How to configure nginx to ensure that the frps server and web share port 80
- First of all, you will have a doubt, what is frp? Simply put, frp is an intranet penetration tool. After configuring the client, you can access the intranet through the server. Now my server has used nginx as the website, and there is only one port 80. So what should I do if the FRP server also wants to use port 80? After querying, this can be achieved by using nginx's reverse proxy. To add: frps is the server, frpc is the client. Step 1: Modify the nginx.conf configuration file in the server and add the following parameters to http{} in nginx.conf, server{listen80

- How to implement nginx reverse proxy in Centos7
- The reverse proxy server is set up on the server side to relieve the workload of the server by buffering frequently requested pages, forwarding client requests to the target server on the internal network; and returning the results obtained from the server to the Internet to request a connection. At this time, the proxy server and the target host appear as a server to the outside world. Currently, web websites use reverse proxies, which in addition to preventing vicious attacks from the external network on internal servers, caching to reduce server pressure and access security control.

- What is the reason why docker uses daemon off when running nginx?
- Question 1. Why does the docker container hang when it is running? By default, the docker container will use the first process inside the container, that is, the program with pid=1, as the basis for whether the docker container is running. If the docker container pid hangs, the docker container will exit directly. 2. When docker runs, use command as the internal command of the container. If you use nginx, then the nginx program will run in the background. At this time, nginx is not the program with pid 1, but the executed bash. This bash will hang after executing the nginx command. , so the container also exited. The same reason as yours. After pm2start, bash

- How to configure the specified save file name for file download in nginx
- Generally, after we upload the resource file, in order to avoid file name conflicts, we will change the file name to a meaningless period of characters. This character may be generated by md5, or a string generated by other methods. At this time, when downloading, the file name saved by default will be this meaningless file name (Figure 1). In fact, nginx supports renaming during downloading, making the file name more friendly. nginx is also easy to configure: just add the following lines: Copy the code The code is as follows: location~*.*\.(doc|txt|jar|zip|apk)(\?.*)?${if($request_uri ~*^.*\/(.*)\.(doc|txt|jar
