LAMP架构介绍

阅读更多关于 LAMP架构介绍

介绍一下LAMP架构　　LMAP即Linux+Apache+Mysql/MariaDB+Perl/PHP/Python的首字母缩写。这是一组常用来搭建动态网站或者服务器的开源软件。它们本身都是各自独立的程序，但是因为常被放在一起使用，拥有了越来越高的兼容度，共同组成了一个强大的Web应用程序平台。随着开源潮流的蓬勃发展，开放源代码的LAMP已经与J2EE和.Net商业软件形成三足鼎立之势，并且该软件开发的项目在软件方面的投资成本较低，因此受到整个IT界的关注。从网站的流量上来说，70%以上的访问流量是LAMP来提供的，LAMP是最强大的网站解决方案。 Linux 　　Linux是一套免费使用和自由传播的类Unix操作系统，是一个基于POSIX和UNIX的多用户、多任务、支持多线程和多CPU的操作系统。它能运行主要的UNIX工具软件、应用程序和网络协议。它支持32位和64位硬件。Linux继承了Unix以网络为核心的设计思想，是一个性能稳定的多用户网络操作系统。 Apache 　　Apache HTTP Server（简称Apache）是Apache软件基金会的一个开放源码的网页服务器，可以在大多数计算机操作系统中运行，由于其多平台和安全性被广泛使用，是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩展，将Perl/Python等解释器编译到服务器中。

How Can I Block Requests from China to My App?

阅读更多关于 How Can I Block Requests from China to My App?

问题 I have an API that is somewhat popular (10,000+ requests/day). After 10 requests per day from an IP address I return a message telling the user they need to cough of some cash if they want to use the service more. This morning, I found that my web service was running terribly slow. I checked out the DB and I was getting absolutely spammed with requests from IP addresses originating in China. They would use an IP address 10 times and then increment the last octet. Sad times. I'd like to limit

Best way to dynamically schedule reminder email? Anything better than cron?

阅读更多关于 Best way to dynamically schedule reminder email? Anything better than cron?

Greetings, I am developing a web app. One piece of it will allow users to schedule a "reminder" email to be sent to them at a particular time of day. What is the best way to accomplish this? Basically, all the solutions I've come up with operate on a "polling" pattern when what I want is an "interrupt" pattern. Here are some possible solutions I've come up with: Have a cronjob fire every minute. The script that fires checks a database to see if there are any emails to send, if there are, it sends them, else it goes back to sleep. Drawback with this is that there is a bit of overhead incurred

What's a good way to encapsulate data access with PHP/MySQL?

阅读更多关于 What's a good way to encapsulate data access with PHP/MySQL?

问题 Most of my experience is on the MSFT stack, but I am now working on a side project, helping someone with a personal site with cheap hosting that is built on the LAMP stack. My options for installing extras are limited, so I'm wondering about how to write my data access code without embedding raw queries in the .php files. I like to keep things simple, even with .NET. I generally write stored procedures for everything, and I have a helper class that wraps all calls to execute procedures and

问题 I'm working on a new server and I installed via yum the "Web Server" group. Php and mysql work fine but I can't get .htaccess to work. Heres my test .htaccess file: WASD_TEST_CALL_ERROR I put this as .htaccess in a test folder along with an index.html page. Instead of reporting an error it goes ahead and loads the index page without displaying any errors. Thanks 回答1: Make sure AccessFileName set to .htaccess Search httpd.conf for AccessFileName directive. It defines name of the distributed

What is the fastest and most efficient way of storing and fetching images when you have millions of users on a LAMP server?

阅读更多关于 What is the fastest and most efficient way of storing and fetching images when you have millions of users on a LAMP server?

Here is the best method I have come up with so far and I would like to know if there is an even better method (I'm sure there is!) for storing and fetching millions of user images: In order to keep the directory sizes down and avoid having to make any additional calls to the DB, I am using nested directories that are calculated based on the User's unique ID as follows: $firstDir = './images'; $secondDir = floor($userID / 100000); $thirdDir = floor(substr($id, -5, 5) / 100); $fourthDir = $userID; $imgLocation = "$firstDir/$secondDir/$thirdDir/$fourthDir/1.jpg"; User ID's ( $userID ) range from

How Did You Decide Between WISA and LAMP? [closed]

阅读更多关于 How Did You Decide Between WISA and LAMP? [closed]

Did you ever have to choose between WISA or LAMP at the beginning of a web project? While pros and cons are littered around the net, it would be helpful to know about your real experience in coming up w/ criteria, evaluating, deciding, and reflecting upon your decision to go w/ either platform. Michael Stum I think the first part is your Application. If you decide to go PHP, you almost automatically end up with LAMP, as WIMP or WISP stacks are quite rare (I think blog.stackoverflow.com runs on WIMP), and with .net you definitely want to go WISA. So normally, it boils down to .net vs. PHP.
