安裝 php-rabbit: RabbitMQ 的 PHP 擴展

RabbitMQ 官方提供了三種 PHP 可用的擴展，分別是：
php-amqp

http://code.google.com/p/php-amqp/

php-rabbit

http://code.google.com/p/php-rabbit/

php-amqplib

http://code.google.com/p/php-amqplib/

這裏我選擇使用 php-rabbit，由於這個項目的 Activity 比較高，名字也比較權威

安裝步驟：

下載 RabbitMQ-C 客戶端庫 librabbitmq：

http://hg.rabbitmq.com/rabbitmq-c/

下載 RabbitMQ 協議代碼生成工具：

http://hg.rabbitmq.com/rabbitmq-codegen/

注意 librabbitmq 的版本號，使用最新版本可能會致使下面編譯 php-rabbit 時出錯：

看了下是頭文件 /usr/local/include/amqp_framing.h 中的結構體定義與源代碼中衝突，所以懷疑是 librabbitmq 版本的問題。
使用 svn 上的代碼也不行，很明顯當前版本不適用。

看到官方下載頁面上的聲明：

Specification
The current RabbitMQ server and Java client library releases implement AMQP protocol version 0-8. The .NET/C# client implements AMQP protocol versions 0-8 and 0-9.

估計得用 0.8 版，我使用如下方式安裝 librabbitmq 時能夠編譯經過：

wget http://hg.rabbitmq.com/rabbitmq-c/archive/ce1eaceaee94.tar.gz -O rabbitmq-c.tar.gz
tar zxf rabbitmq-c.tar.gz
wget http://hg.rabbitmq.com/rabbitmq-codegen/archive/c7c5876a05bb.tar.gz -O rabbitmq-codegen.tar.gz
tar zxf rabbitmq-codegen.tar.gz
mv rabbitmq-codegen-c7c5876a05bb/ rabbitmq-c-ce1eaceaee94/codegen
cd rabbitmq-c-ce1eaceaee94/
autoreconf -i && ./configure && make && make install

若是提示：

checking finding a python with simplejson installed… configure: error: could not find a python that can ‘import simplejson’

請安裝 python 的 simplejson 庫：

# wget http://pypi.python.org/packages/source/s/simplejson/simplejson-2.1.1.tar.gz
# tar zxf simplejson-2.1.1.tar.gz
# cd simplejson-2.1.1
# python setup.py install

下載並安裝 php-rabbit：

# wget http://php-rabbit.googlecode.com/files/php-rabbit.r91.tar.gz
# tar zxf php-rabbit.r91.tar.gz
# cd php-rabbit
# /usr/local/php/bin/phpize
# ./configure –with-php-config=/usr/local/php/bin/php-config –with-rabbit
# make && make install

修改 php.ini，在尾部加上：
extension = rabbit.so

查看擴展是否安裝成功：
# php -m | grep rabbit
rabbit

完工！！
