在安装predis扩展之前先安装composer，安装教程在：

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"php -r "if (hash_file('SHA384', 'composer-setup.php') === 'c32408bcd017c577ce80605420e5987ce947a5609e8443dd72cd3867cc3a0cf442e5bf4edddbcbe72246a953a6c48e21') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"php composer-setup.phpphp -r "unlink('composer-setup.php');"

接着把composer设置全局环境变量：

mv composer.phar /bin/composer

把composer镜像地址改为国内的会快很多，教程地址：

composer config -g repo.packagist composer https://packagist.phpcomposer.com

然后开启php-pear，php-devel和php-redis扩展，我是直接用CentOS 的yum包来安装扩展：

yum -y install php70w-devel.x86_64yum install php70w-pear.noarchyum -y install php70w-pecl-redis.x86_64

安装完成后切换到你的网站根目录下，成功后如图所示：

composer require predis/predisUsing version ^1.1 for predis/predis./composer.json has been updated> php artisan clear-compiledLoading composer repositories with package informationUpdating dependencies (including require-dev)  - Installing predis/predis (v1.1.1)    Downloading: 100%         predis/predis suggests installing ext-phpiredis (Allows faster serialization and deserialization of the Redis protocol)Writing lock fileGenerating autoload files> php artisan optimize

 

接着就可以在你的Controller中使用 use Redis 来各种操作了。
