PHP uses Redis

Installation

Before you start using Redis in PHP, We need to ensure that the redis service and PHP redis driver have been installed, and that PHP can be used normally on your machine. Next, let us install the PHP redis driver: The download address is: https://github.com/phpredis/phpredis/releases.

PHP installation redis extension

The following operations need to be completed in the downloaded phpredis directory:

$ wget https://github.com/phpredis/phpredis/archive/2.2.4.tar.gz
$ cd phpredis-2.2.7                      # 进入 phpredis 目录
$ /usr/local/php/bin/phpize              # php安装后的路径
$ ./configure --with-php-config=/usr/local/php/bin/php-config
$ make && make install

If you are PHP7 version, you need to download the specified branch:

git clone -b php7 https://github.com/phpredis/phpredis.git

Modify the php.ini file

vi /usr/local/php/lib/php.ini

Add the following content:

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626"

extension=redis.so

Restart php-fpm or apache after the installation is complete. Check the phpinfo information and you can see the redis extension.
