What is the method for smooth upgrade of Nginx production environment?

What is the method for smooth upgrade of Nginx production environment?

1. Background Recently I encountered a rather embarrassing and practical problem, that is, the Nginx used in our production environment is an old antique of Centos6. Business requirements need to be implemented by loading a module of Nginx, but the version is too old and needs Nginx1.18 or later to support it, and ours is Nginx1.12. Then upgrading Nginx is what we have to do. But in the production environment, you have to consider many things. Unlike the test server, Nginx stops the service, recompiles the new version, and then starts it again. Our online services need to be provided uninterrupted, otherwise it will cause economic losses to the business. So is there any plan to smoothly upgrade the Nginx version? 2. Upgrade plan In fact, the official has long been aiming at smooth upgrade of Nginx.

How to configure Nginx server for Node.js program

How to configure Nginx server for Node.js program

Node.js is a platform built on the Chrome JavaScript runtime, which is used to easily build web applications with fast response speed and easy expansion. Node.js uses an event-driven, non-blocking I/O model to be lightweight and efficient. It is very suitable for data-intensive real-time applications running on distributed devices, such as real-time chat and so on. However, gzip encoding, static files, http caching, SSL processing, load balancing and reverse proxy, etc., can all be completed through nginx, thereby reducing the load on node.js and saving website traffic through nginx's powerful cache. Improve website loading speed. The flow chart nginx configuration is as follows: http{proxy_

How to obtain the user's real IP address based on nginx reverse proxy

How to obtain the user's real IP address based on nginx reverse proxy

Introduction When nginx is used as a reverse proxy, the IP address obtained by the default configuration backend comes from nginx. Use request.getRemoteAddr(); to obtain the IP address of nginx, not the user's real IP. 1. Modify Nginx Configuration: server{listen80;server_namejenkins.local.com;location/{proxy_set_headerHost$host;proxy_set_headerX-Real-IP$remote_addr;proxy_passhttp://192.168.10.

How to solve nginx 503 Service Temporarily Unavailable error

How to solve nginx 503 Service Temporarily Unavailable error

Recently, the 503servicetemporarilyunavailable error often appears after the website is refreshed. Sometimes it is possible. I think of the recent restriction on the number of single IP accesses in nginx.conf, (limit_req_zone$binary_remote_addrzone=allips:20mrate=20r/s;) and enlarge this number before refreshing. Problems found and solved. (I also changed this to a larger limit_reqzone=allipsburst=50nodelay;) In order to confirm the problem, I repeatedly changed the number and tested it and found that the problem is indeed here. There is a problem if this number is set too small. Pass fid

How to use geoip for regional restrictions in nginx

How to use geoip for regional restrictions in nginx

Environment: nginxversion:nginx/1.14.0centosversion:centos7 The requirements are as follows: distinguish domestic or foreign countries through IP, so as to jump to different pages, and finally use nginx’s third-party module: geoip to achieve this, let alone its advantages. There are many explanations on the Internet. Let’s see how to configure it. My system is configured with nignx.repo. I directly used yum to install the geoip module. There is no need to add the module and reprogram it. yuminstallnginx-module-geoip downloads the geoip database file cd/ etc/nginxmkdirgeoipdatcdg

How to use Nginx to proxy multiple application sites in Docker

How to use Nginx to proxy multiple application sites in Docker

How to proxy (how do containers communicate)? Just use the proxy function of nginx directly (see related capabilities separately). The troublesome thing here is the communication between docker containers. There are four main methods of communication between docker containers: -Access through container IP: After the container is restarted, the IP will change. -Access through the host's ip:port method: If the host's IP changes, each application must be changed and the port must be bound, which is troublesome. - Establishing links through links: interdependence is too tight and is not conducive to maintenance. - Custom network: Containers in the same bridge network can access each other. Obviously, we will choose to customize the network so that related applications can link to the same

How to configure Nginx reverse proxy using SSL

How to configure Nginx to implement encryption certificate access

How to configure Nginx to implement encryption certificate access

Enterprise use: Some enterprises require encryption of company data for security measures. Web encryption is also an important part, so you need to add a self-built certificate. Install the certificate. Remember three types of files, the basic CA certificate and the secondary CA certificate (containing some company personal information, used to identify the owner of the certificate), and then use this certificate to generate a real certificate for distribution and use. opensslgenrsa-des3-outca.key2048#ca level 1 private key (will require you to enter the password twice in succession, remember to keep it the same) opensslreq-new-keyca.key-outserver.csr#Level 2 encrypted file generated based on the private key (will Let's enter the private key password, CN, BJ, B
