1.查看当前默认php版本
php -v
我这里是7.2
PHP 7.2.24 (cli) (built: Jun  7 2020 19:31:17) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies


2.安装rabbitmq-c

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

tar zxf rabbitmq-c-0.8.0.tar.gz

cd rabbitmq-c-0.8.0

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

make && make install 


3.安装amqp

官网：http://pecl.php.net/package/amqp查看最新版本
 

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

tar zxf amqp-1.9.3.tgz

cd amqp-1.9.3

/usr/local/php7.2/bin/phpize

./configure --with-php-config=/usr/local/php7.2/bin/php-config --with-amqp --with-librabbitmq-dir=/usr/local/rabbitmq-c-0.8.0

make && make install

4.修改php7.2的php.ini配置文件

vi /usr/local/php/etc/php.ini

增加 extension = /usr/local/php7.2/lib/php/extensions/no-debug-non-zts-20170718/amqp.so 

systemctl restart php-fpm7.2.service

5.查看php扩展
 php -m
