Linux教程之ubuntu下手动编译php-amqp扩展教程
首先,神马是amqp?介绍在这里,简单的讲就是高级队列协议。而这个扩展就是为了让php可以支持amqp协议与相关的队列服务通讯。
优点:可以解决服务器处理的并发问题。
高级消息队列协议(AMQP)是一个异步消息传递所使用的应用层协议规范。作为线路层协议,而不是API(例如JMS),AMQP 客户端能够无视消息的来源任意发送和接受信息。现在,已经有相当一部分不同平台的服务器和客户端可以投入使用。
(一)基本概念
RabbitMQ 是流行的开源消息队列系统,用erlang语言开发。RabbitMQ是AMQP(高级消息队列协 议)的标准实现。如果不熟悉AMQP,直接看RabbitMQ的文档会比较困难。不过它也只有几个关键概念,这里简单介绍。
几个概念说明:
(二)使用流程
即 Client - AMQP server - Client
左边的Client向右边的Client发送消息,流程:
由于ubuntu的默认源里面没有php5-amqp这个包,所以要用上amqp得考手动编译。
准备工作:
安装php编译工具
<code>sudo apt<span>-get</span> install php5<span>-dev</span></code>
安装rabbitmq的库
<code>sudo apt<span>-get</span> install librabbitmq<span>-dev</span></code>
如果你的Linux发行版没有现成的librabbitmq-dev包,那么可以通过下载源码编译安装
然后如果你没有安装git话请安装一下git,因为我们要从官方的版本库中获取源代码
克隆源码并编译
<code>git <span>clone</span> git:<span>//<strong>github</strong>.com/alanxz/rabbitmq-c.git</span> cd rabbitmq-c git submodule init git submodule update</code>
编译库
<code>autoreconf -i && ./configure && <span>make</span> && sudo <span>make</span> install</code>
然后我们需要去下载php扩展的源代码,地址在此:
http://pecl.php.net/package/amqp
当前最新版本为1.4.0
<code>wget http://pecl<span>.php</span><span>.net</span>/get/amqp-<span>1.4</span><span>.0</span><span>.tgz</span>tar zxf amqp-<span>1.4</span><span>.0</span><span>.tgz</span> cd amqp-<span>1.4</span><span>.0</span>/ phpize && ./configure --with-amqp && make && sudo make install</code>
创建配置文件
<code><span>sudo</span><span>echo</span><span>"extension = amqp.so"</span> > /etc/php5/conf.d/amqp.ini</code>
然后重启你的web服务器或者php-fpm并打印phpinfo,如果见到以下的内容就说明扩展安装好了
