PHP使用RabbitMQ（正常连接与开启SSL验证后的连接）

代码中包含了PHP在一般情况下使用方法和RabbitMQ开启了SSL验证后的使用方法（我这边消费队列是使用接口请求的方式，每次只从中取出一条）

安装amqp扩展

PHP使用RabbitMQ前，需要安装amqp扩展，之前文章中介绍了Windows环境PHP安装amqp扩展的方法：windows环境PHP使用RabbitMq安装amqp扩展_windows mq扩展安装-CSDN博客

Linux中安装amqp扩展：

### 先进入/usr/local目录下，下载两个文件到此目录（我的PHP版本是7.2）：

wget -c https://github.com/alanxz/rabbitmq-c/releases/download/v0.8.0/rabbitmq-c-0.8.0.tar.gz

wget -c http://pecl.php.net/get/amqp-1.9.3.tgz

### 若使用的docker，将上面下载的两个包 拷贝到容器内【 docker cp ./文件 dockerID:/usr/local】，然后执行下面命令即可

### 解压rabbitmq-c-0.8.0.tar.gz

tar zxf rabbitmq-c-0.8.0.tar.gz

cd /usr/local/rabbitmq-c-0.8.0

./configure --prefix=/usr/local/rabbitmq-c-0.8.0

make && make install

### 然后解压 amqp-1.9.3.tgz 解压后amqp-1.9.3文件下内还有个amqp-1.9.3文件夹，将内部的amqp-1.9.3目录拷贝到/usr/local/下，执行下列命令：

cd /usr/local/amqp-1.9.3

/usr/local/bin/phpize

./configure --with-php-config=/usr/local/bin/php-config --with-amqp --with-librabbitmq-dir=/usr/local/rabbitmq-c-0.8.0

cp /usr/local/rabbitmq-c-0.8.0/librabbitmq/amqp_ssl_socket.h /usr/local/amqp-1.9.3/

make && make install

### 最后修改php.ini    加上配置：

extension = amqp.so

安装后，执行php -m 显示amqp 即表明扩展安装成功！

加载PHP代码的扩展包

然后需要加载代码的扩展包，比较方便快捷的方法是使用composer 加载扩展包

composer require php-amqplib/php-amqplib

若想指定版本：composer require php-amqplib/php-amqplib:版本

具体使用哪个版本可以在此链接内查询：https://packagist.org/packages/php-amqplib/php-amqplib
