安装
开始在 PHP 中使用 Redis 前， 我们需要确保已经安装了 redis 服务及 PHP redis 驱动，且你的机器上能正常使用 PHP。 接下来让我们安装 PHP redis 驱动：下载地址为:https://github.com/phpredis/phpredis/releases。 ### PHP安装redis扩展
以下操作需要在下载的 phpredis 目录中完成： `
$ 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
> 如果你是 PHP7 版本，则需要下载指定分支： ```
> <span class="pln">git clone </span><span class="pun">-</span><span class="pln">b php7 https</span><span class="pun">:</span><span class="com">//github.com/phpredis/phpredis.git</span>
> ```
### 修改php.ini文件
vi /usr/local/php/lib/php.ini
增加如下内容: ```
<span class="pln">extension_dir </span><span class="pun">=</span> <span class="str">"/usr/local/php/lib/php/extensions/no-debug-zts-20090626"</span><span class="pln">
extension</span><span class="pun">=</span><span class="pln">redis</span><span class="pun">.</span><span class="pln">so</span>安装完成后重启php-fpm 或 apache。查看phpinfo信息，就能看到redis扩展。
