I, college non-trained, self-study php+js into the profession. In the 5th year, in 2 companies, the first stayed for 3 years, now this family has been 2 years. The first company learned to lnmp the basic skills of the web development front and back in the environment, learning about Python. and Java,java only part of the task in a project, and now only a vague memory. The last 2 years after the change of work, my own planned learning route was interrupted, has been the company's business led by

: This article mainly introduces the [nginx] Daily automatic log cutting script. if you are interested in the PHP Tutorial, please refer to it. When the daily log volume of nginx is large, it is best to automatically cut and store the logs every day, which can be used for future query and analysis. #!/bin/sh####################filename: nginx_log_rotate.sh#vsersion: 0.1v#1 0 * * * /bin/sh /home/project/monitor/nginx_log_rotate.sh >/dev/null 2>1###################logs_path="/usr/local/

The common Nginx load scheme has Round-robin,least-connected,ip-hash, but these three kinds do not satisfy the demand very well, when backend increases, if uses the NODEJS official plan to synchronize with all messages between the service, Can cause a very large amount of synchronization.Solution: forwar

OCSP real-time queries increase the client's performance overhead. Therefore, it is p

header to Image/gif. Set some required cookie information in the response header via Set-cookie. The reason to set a cookie is that if you want to track a unique visitor, it is common practice to generate a globally unique cookie based on the rule and plant it to the user if the client does not have the specified trace cookie on the request, otherwise the tracked cookie that is obtained in Set-cookie is placed To keep the same user cookie intact. While this is not perfect (for example,

increase will appear a lot of failure test. Gevent is good enough, but it's a bit unscientific to be slower than Gunicorn's sync mode. The advantage of Gunicorn is that it is easy to manage, and can be flexible to use a variety of work_class, particularly strange that the sync mode is also so fast. The performance impact of web.py is still obvious. The impact of the template is also obvious--mako is already a quick template, I really do not know how to use those kid slow template will be what e

Good fast, one months later, feel that they learn less, also feel a bit of a qualitative leap. Previously used openresty, how to say, also very valuable, high concurrency, load balancing, in some kind of small game can be a try, in fact, I have ideas,,, but used to do the game on the development of this, too no development prospects,, after all, I think, at least a lot of important programming ideas, design patterns better , after all, is not the dir

, multiple process instances are usually started on multiple servers, use Nginx as a reverse proxy server on the front end to distribute web requests and load balancing. Nginx is written in C, with better concurrency and configurability, and better support for static files. Of course, this is a common scenario of Nginx, in fact, you can directly use Nginx to build web applications, you can refer to the OpenResty Project (http://openresty.org/ ). In f
