Twemproxy Lag Forces a Restart

We are running a PHP stack on our app servers which use twemproxy locally (via socket), to connect to multiple upstream memcached servers (EC2 small instances) for our caching layer. Every so often I get an alert from our app monitor that a page load time takes > 5 seconds. When this occurs, the immediate fix is to restart the twemproxy service on each app server, which is a hassle. The o

Twemproxy Lag强制重启

我们在本地使用twemproxy(通过套接字)的应用程序雅博国际顶级上运行PHP堆栈,以连接到缓存层的多个上游memcached雅博国际顶级(EC2小型实例)。 每隔一段时间,我都会从我们的应用程序监视器得到一个警报,即页面加载时间大约需要5秒。 发生这种情况时,立即修复是在每台应用程序雅博国际顶级上重新启动twemproxy服务,这很麻烦。 我现在唯一的解决方法是每分钟运行一次并重新启动服务的crontab,但正如您可以想象的,每分钟都不会写入数秒

How keywod 'finally' is meant to be used in PHP

So, I have been reading about the exceptions today on the PHP online manual, and realize I have yet to understand the purpose or real necessity of the finally keyword. I have read some posts here, so my question is slightly different. I understand that we can use finally in this way: function hi(){ return 'Hi'; } try { throw new LogicException("Throw logic n"); } catch (InvalidArgum

keywod'finally'如何在PHP中使用

所以,我一直在阅读关于PHP在线手册中的例外情况,并意识到我还没有理解finally关键字的目的或真正的必要性。 我在这里看过一些帖子,所以我的问题稍有不同。 我明白我们可以最终以这种方式使用: function hi(){ return 'Hi'; } try { throw new LogicException("Throw logic n"); } catch (InvalidArgumentException $e) { echo $e->getMessage(); } echo hi(); 输出: Fatal error: Uncaught LogicE

how to make a htaccess rule from id to name

I have a list of unique data: Suppose I have the following data: id name 1 Jhon 2 Peter 3 Mark 4 Scotty 5 Marry I make a .htaccess rule for id : RewriteRule brandlisting/(.*)/ site/brandlisting?id=$1 [L] RewriteRule brandlisting/(.*) site/brandlisting?id=$1 [L] my URL is: http://localhost/mate/admin/site/brandlisting/3 this works for id.

我有一个独特的数据列表: 假设我有以下数据: id name 1 Jhon 2 Peter 3 Mark 4 Scotty 5 Marry 我为id做了一个.htaccess规则: RewriteRule brandlisting/(.*)/ site/brandlisting?id=$1 [L] RewriteRule brandlisting/(.*) site/brandlisting?id=$1 [L] 我的网址是: http://localhost/mate/admin/site/brandlisting/3 这适用于id。 现在我需要一个名称为.htaccess规则,所以我为它制定了

Detect encoding and make everything UTF

I'm reading out lots of texts from various RSS feeds and inserting them into my database. Of course, there are several different character encodings used in the feeds, eg UTF-8 and ISO-8859-1. Unfortunately, there are sometimes problems with the encodings of the texts. Example: 1) The "?" in "Fu?ball" should look like this in my database: "??". If it is a

检测编码并使所有的UTF

我从各种RSS源中读出大量文本并将它们插入到我的数据库中。 当然,Feed中使用了几种不同的字符编码,例如UTF-8和ISO-8859-1。 不幸的是,文本的编码有时会出现问题。 例: 1)“Fu?ball”中的“?”在我的数据库中应该如下所示:“??”。 如果是“??”,则显示正确。 2)有时,“Fu?ball”中的“?”在我的数据库中看起来像这样:“????”。 然后,它显示错误,当然。 3)在其他情况下,“?”被保存为“?” - 所以没有任何改变。 然后

Adding Metada and Options to S3 Objects when uploading a directory

I am successfully uploading folders to S3 using ->uploadDirectory() . Several hundred folders have 100's, or 1,000's of images contained within them with so using PutObject() for each file hardly seemed to make sense. The upload works, and all goes well, but the ACL, StorageClass, and metadata is not being included in the upload. According to the docs at http://docs.aws.amazon.com/

上传目录时,将Metada和选项添加到S3对象

我正在使用->uploadDirectory()成功上传文件夹到S3。 几百个文件夹有100个或1000个图像,因此每个文件使用PutObject()几乎看起来没什么意义。 上传工作正常,并且一切顺利, 但ACL,StorageClass和元数据未包含在上传中。 根据http://docs.aws.amazon.com/aws-sdk-php/v2/guide/service-s3.html#uploading-a-directory-to-a-bucket上的文档,应该完成以下代码这个。 它还被引用的putObject()函数记录下来。 除了目录和

Amazon EC2, S3, REST API, and how to correctly provide contents to users

I have deployed a REST server in an Amazon EC2 instance. I have also configured an Amazon S3 bucket to store all the data generated by users while interacting with the API. The main information stored are images. Users can upload images by doing a PUT HTTP request over certain URL and credentials. The PUT request may be done over the EC2 instance, since the upload needs to be authorized and u

Amazon EC2,S3,REST API以及如何向用户正确提供内容

我在Amazon EC2实例中部署了REST雅博国际顶级。 我还配置了一个Amazon S3存储桶来存储用户在与API交互时生成的所有数据。 存储的主要信息是图像。 用户可以通过对某些URL和凭证执行PUT HTTP请求来上传图像。 PUT请求可以通过EC2实例完成,因为上传需要授权,用户不能直接访问S3实例。 当EC2收到有效的PUT请求时,我使用AWS PHP SDK将对象上传到S3存储桶。 我使用的方法是putObject。 对于第一部分,我认为没有更多的选择。 不
