change of the backend. This is also like CONFD and other open source tools. CONFD based on the Golang template Library, the Nginx configuration files as templates, support Consul/etcd/redis/zookeeper and many other back-end storage, through watch or scheduled scheduling from these back-end to obtain instance information, and update to Nginx profile template, so as to achieve (quasi) real-time 7-tier dynamic routing. This implementation logic is simple, high stability, but in large-scale applica

This is a creation in Article, where the information may have evolved or changed. Go Language Advantages: • Static language, strongly typed. Static compilation can help us to check out a lot of errors, the strong type of go and even perverted to not support implicit type conversion. Gofmt, it's supposed to be the first one I know. The language of the Uniform Format Code tool is provided. With GOFMT, everyone's code is the same, there is no curly braces in the end or a new line of this kind of eg

place where many people spit out python, but Python has something to do with it, and it's hard to use Python to develop some high-performance modules. python Gil leads to the inability to really multi-threading, People may say that I use a lot of process is not finished. However, if some computations involve multi-process interaction, the communication overhead between processes has to be considered. But even if we use multiple Django processes to handle HTTP requests , Python still can't h

files, which is very inconvenient to troubleshoot the problem. Remotetail to solve this problem, developers can use it to display the log information of two (multiple) servers synchronously. Installation Download bin/ the corresponding executable file under the project remote-tail-平台 and add the file to the PATH directory specified in the environment variable of the system. For example, a directory can be placed under CentOS /usr/local/bin . mv remote-tail-linux /usr/local/bin/remote-tail How t

Today began to embark on the road to business, feeling and work when the same, or all day to the computer. But the time is assigned by themselves, this is my happiest, and can also go to their favorite direction of development, is just beginning money less. Do not know the back will not be reduced to even eat bubble noodles of money have not? Try to do it, if it really fell to that point I have no way.Yesterday rented a CENTOS7 server, early in the morning to get up and configure the environment

Well, today, the Nginx reverse proxy server function and how to use LUA to encapsulate the JSON package of the relevant knowledge points to figure out, it is bad practice, so it took 6 hours to go down a centos7 mirror, slow speed is a waste of time.In fact, has been very curious about what is "reverse proxy", since there is a reverse, it must be positive. In fact, we use the proxy server is a "forward" server, is to access a server, need to operate through this agent, the destination server is

Greenev-Python Asynchronous Network Service Framework, greenevpython Greenev is a Python network service framework based on greenlet coroutine, event-driven, and non-blocking socket model. It enables synchronous code writing, but achieves the advantages of asynchronous execution.This project was inspired by gevent, openresty, alilua, skynet, clowwindy/ssloop, and I would like to express my gratitude here. The reactor mode adopts IO multiplexing base

Install Nginx-echo module in Nginx Nginx-echo can be used to output some information in Nginx. It is a good tool for testing troubleshooting. It can also make a summary of the information from different link addresses. In short, it can help developers. Next let's take a look at how to install and use it. 1. Download Nginx-echo Cd/usr/local/nginx-1.12.2/Wget https://github.com/openresty/echo-nginx-module/archive/v0.60.tar.gz 2. decompress the downloade

Tengine is a Web server project launched by Taobao. Based on Nginx, it adds many advanced functions and features to meet the needs of high-traffic websites. It is currently open-source. It is developed and maintained by the Tengine team. Core members of the Tengine team are from Internet companies such as Taobao and Sogou. Tengine inherits all Nginx features and is 100% compatible with Nginx configurations. This article describes how to use "dynamic module loading (DSO.What is "dynamic

Nginx uses the Ngx_headers_more module to add, remove outbound, inbound Header information.Ngx_headers_more Project homepageThe default module is not included in the Nginx source code, and to use the related functionality, you need to include the module when compiling Nginx.Nginx in my server did not join the module at compile time, use-V to view the current Nginx compilation parameters: [Root@z-dig ~]# Nginx-vNginx version:www.111cn.netBuilt by GCC 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)Built

Why write this, mainly a small partner asked me how to debug nginx some information. So I thought of this echo module of Chun-brother. 1, download the Echo module: wget--no-check-certificate Https://github.com/openresty/echo-nginx-module/archive/v0.58.zip 2. Copy to a module directory: Unzip V0.58.zipNew directory:/usr/local/nginx/moduleCp-r echo-nginx-module-0.58//usr/local/nginx/module 3, recompile nginx, note to the original module compilation
