How does if condition work inside location block in nginx conf?

假如想象 提交于 2021-01-27 06:31:04
问题 I have read https://www.nginx.com/resources/wiki/start/topics/depth/ifisevil/ I want to check if my rails application has already added a header ( Access-Control-Allow-Origin ) and if it hasn't then add the header. The examples here have tried to explain the behaviour of if condition in nginx.conf http://agentzh.blogspot.in/2011/03/how-nginx-location-if-works.html But I have not understood it. One of the question I have is what is meant when they say a directive or phase directive? I have

Docker best practices: single process for a container

a 夏天 提交于 2021-01-27 04:37:53
问题 The Docker best practices guide states that: "...you should only run a single process in a single container..." Should Nginx and PHP-FPM run in separate containers? Or does that mean that micro service architectures only run one service or "app" in a container? Having these services in a single container seems easier to deploy and maintain. 回答1: Depending on the use case, you can run multiple processes inside a single container, although I won't recommend that. In some sense it is even

针对海量数据和高并发的主要解决方案

百般思念 提交于 2021-01-27 02:06:31
一、网站应用背景 开发一个网站的应用程序,当用户规模比较小的时候,使用简单的:一台应用服务器+一台数据库服务器+一台文件服务器,这样的话完全可以解决一部分问题,也可以通过堆硬件的方式来提高网站应用的访问性能,当然,也要考虑成本的问题。 当问题的规模在经济条件下通过堆硬件的方式解决不了的时候,我们应该通过其他的思路去解决问题,互联网发展至今,已经提供了很多成熟的解决方案,但并不是都具有适用性,你把淘宝的技术全部都搬过来也不一定达到现在淘宝的水平,道理很简单。 2.1、海量数据的解决方案: 使用缓存; 页面静态化技术; 数据库优化; 分离数据库中活跃的数据; 批量读取和延迟修改; 读写分离; 使用NoSQL和Hadoop等技术; 分布式部署数据库; 应用服务和数据服务分离; 使用搜索引擎搜索数据库中的数据; 进行业务的拆分; 2.2、高并发情况下的解决方案: 应用程序和静态资源文件进行分离; 页面缓存; 集群与分布式; 反向代理; CDN; 三、海量数据的解决方案 3.1、使用缓存 网站访问数据的特点大多数呈现为“二八定律”:80%的业务访问集中在20%的数据上。 例如:在某一段时间内百度的搜索热词可能集中在少部分的热门词汇上;新浪微博某一时期也可能大家广泛关注的主题也是少部分事件。 总的来说就是用户只用到了总数据条目的一小部分,当网站发展到一定规模,数据库IO操作成为性能瓶颈的时候

最近做大数据面试官的感想

时间是不可逆的,我们不可能经历之后,然后再返回来修正自己过去的行为,但是我们可以通过观察不同时间段的相同职业人的现状来修正自己。 最近一段时间,浪尖忙于招人面试,在面试别人的过程中收获了很多,我相信被我面试的人也会收获很多。 面试者的工作经验有十年以上的,有五六年,还有两三年的,每个年龄段都有自己的优点和缺点(这是句废话,每个人都是优缺点参半,实际上强调的是技术实力的优缺点),在这里,其实我想表达的事情是 通过不同年龄段的人在技术及经验方面的表现,可以映射到我们每一个人在不同年龄段的技术及经验的表现,通过多个人的历程来映射或者是分析我们自身在不同年龄段的状况。 对于十年左右工作经验的人 ,一般勤奋的人的资历、技术经验、项目管理经验及整个架构的言语表达都是非常赞的。但是,可能是父母,老婆,孩子等相关人、事耗去了很大的精力,在新技术的学习掌握能力上不是很好,当然了有实战的平台和心劲儿才是这块的关键。当然,这种人我们关注的应该是项目经验、架构能力、管理能力及表达能力,最好对新的技术框架有自己的认识,技术细节等我们不太关注,这个浪尖面试的比较少,原因是因为我们招的是干活的人而不是管干活的人。 对于五年左右工作经验的人 ,正当年,项目经验、技术实力、编程功底、架构能力都应该很赞,但是面试很多个都是什么都接触了,什么都用了,通过问问题和自我描述确实做过, 高考查分 但是架构设计一般般

Docker NGINX Proxy not Forwarding Websockets

≡放荡痞女 提交于 2021-01-26 23:50:08
问题 NGINX proxy is passing HTTP GET requests instead of WebSocket handshakes to my django application. Facts: Rest of the non-websocket proxying to django app is working great. I can get WebSockets to work if I connect to the django application container directly. (Relevant log entries below.) The nginx configuration works localhost on my development machine (no containerizing). (Log example below.) Relevant Logs: Daphne log when connecting through containerized nginx proxy: `xxx.xxx.xxx.xxx

nginx reverse proxy to a set of pages with an additional path in the URL based on http referer?

最后都变了- 提交于 2021-01-26 23:39:11
问题 I have a 3rd-party ui server running in a docker container, exposed on port 8080. It seems to expect to load resources with an absolute path: http://localhost:8080/index.html , http://localhost:8080/js/some_jsfiles etc. I want to create a reverse proxy to it so it looks like it is coming from a different path: https://myserver.com/stormui/index.html , https://myserver.com/stormui/js/... first I tried location /stormui/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr;
