系统版本：

[root@localhost modules]# rpm -q centos-release
centos-release-7-5.1804.el7.centos.x86_64

一、yum安装PHP

1.检查当前安装的PHP包

yum list installed | grep php

如果有安装的PHP包，先删除他们

yum list installed | grep php | awk '{print $1}' | yum remove

2.配置epel源

yum install -y epel-release
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

配置remi源

rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

使用yum list命令查看可安装的包(Packege)

yum list --enablerepo=remi --enablerepo=remi-php56 | grep '@remi-php56'

3.安装php5.6.x

yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-pear php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof --skip-broken

4.安装php-fpm

yum install --enablerepo=remi --enablerepo=remi-php56 php-fpm 

5.配置开机启动服务

systemctl enable php-fpm

6.启动php-fpm

systemctl restart php-fpm

7.查看是否安装成功

ps -ef | grep php
netstat -anp | grep 9000

8.查看PHP版本

[root@localhost modules]# php -v
PHP 5.6.40 (cli) (built: Feb  3 2021 11:47:03)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

    with Xdebug v2.5.5, Copyright (c) 2002-2017, by Derick Rethans

二、安装AMQP扩展

1.安装rabbitmq-c

下载地址：http://github.com/alanxz/rabbitmq-c
选择的版本是0.8.0，从0.9.0开始编译模式换成了CMake

[root@localhost ~]# wget https://github.com/alanxz/rabbitmq-c/releases/download/v0.8.0/rabbitmq-c-0.8.0.tar.gz
[root@localhost ~]# tar zxf rabbitmq-c-0.8.0.tar.gz
[root@localhost ~]# cd rabbitmq-c-0.8.0
[root@localhost ~]# ./configure --prefix=/usr/local/rabbitmq-c-0.8.0
[root@localhost ~]# make && make install

2.安装AMQP

下载地址https://pecl.php.net/package/amqp
选择的是最新版1.10.2

[root@localhost ~]# wget https://pecl.php.net/get/amqp-1.10.2.tgz
[root@localhost ~]# tar zxf amqp-1.10.2.tgz
[root@localhost ~]# cd amqp-1.10.2
[root@localhost ~]# /usr/local/php/bin/phpize
[root@localhost ~]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-amqp --with-librabbitmq-dir=/usr/local/rabbitmq-c-0.8.0
[root@localhost ~]# make && make install

注意：这里的/usr/local/rabbitmq-c-0.8.0要跟上面rabbitmq-c安装的地址一样

3.添加AMQP扩展

vim /etc/php.ini

添加一行

extension=amqp.so

重启php

service php-fpm restart

4.检查amqp安装

[root@localhost modules]# php -m
[PHP Modules]
amqp
bcmath
bz2
calendar

PS:

CentOS 7使用yum安装PHP5.6
