How to use nginx simulation for blue-green deployment

Blue-green deployment The focus of blue-green deployment lies in the following characteristics: 1. The blue version and the green version exist at the same time. 2. The actual running environment is blue or green, and can only be one of them. Analysis of advantages and disadvantages through switch control: The advantages are: It's speed and rollback. And the shortcomings are also obvious. Quick rollback is possible because two sets of environments exist at the same time, so the complexity and required resources will increase because there are two sets of environments. In addition, although the speed has been improved, in the implementation process, the switch control, no matter how fast the switching speed, is still unable to achieve completely seamless switching without combining other technologies. Simulate blue-green deployment Next, we use nginx's upstream to simply simulate the blue-green deployment scenario. The specific scenarios are as follows, currently active

How nginx rewrite implements URL jump

URL jump The URL jump mentioned here is to jump to another URL when the user accesses one URL. A common application scenario is to let multiple domain names jump to the same URL (for example, let the old domain name jump to a new domain name), jump static file requests to CDN, etc. Jump to different sites according to the user's device (PC version) , wap version), etc. URL jump can be achieved by setting the window.location on the page with js or by setting the header with php. Of course, it can also be implemented using the rewrite function of nginx. The nginxrewrite module rewrite is the static rewrite module of nginx. The basic usage is rewritepattenre.

How to configure nginx log scheduled backup and deletion

Once the nginx logging function is turned on, nginx will generate log files of a certain size every day. If the system runs stably and there are no problems, then the logs will basically not be viewed. However, if these logs are not cleared in time, they will accumulate day by day and occupy a terrible amount of disk space on the server. In order to solve this problem, use a shell script to regularly back up and delete nginx log files, and only keep them for a period of time. Figure 1: #!/bin/bash#auth:lzq#desc: Back up the current log by date and regenerate the next day’s log file #date:2016-09-18date=`date+%y%m%d`nginx_pid =`cat/var

How does Nginx realize 404 automatically jump to the home page?

404 automatically jumps to the homepage server{location/{error_page404=@ops-coffee;}location@ops-coffee{rewrite.*/permanent;}}. The 404 page on the website is not particularly friendly. We can use the configuration above to prevent 404 from appearing. Then it will automatically jump to the home page.

What should I do if nginx deploys vue and cannot find the js css file?

Many times after npmrunbuild, the relative directory of the js file and css file automatically inserted by webpack in the index.html file is always wrong. After publishing it to the server, nginx cannot find the file. vue-cli@3 In vue-cli@3 you need to add a baseurl for all files that your webpack inserts into index.html. You need to create a new vue.config.js in the root directory of the project and add the following content:. ..module.exports={baseurl:isprod?'/basexxx/':

Nginx basic introduction to gzip configuration method

Preface gzip (gnu-zip) is a compression technology. After gzip compression, the page size can be reduced to 30% or even smaller than the original size. In this way, users will browse the page much faster. The gzip compressed page needs to be supported by both the browser and the server. It is actually server-side compression. After being transmitted to the browser, the browser decompresses and parses it. We don’t need to worry about the browser, because most current browsers support parsing gzip pages. Whether it is front-end or back-end, nginx is often used when deploying projects, and small projects often use a reverse proxy or something. Today I will be simple and direct and talk about one of the points - gzip. If there are any errors, please correct me. Generally used on the server side is u

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.
