開始在 PHP 中使用 Redis 前, 我們需要確保已經(jīng)安裝了 redis 服務(wù)及 PHP redis 驅(qū)動,且你的機器上能正常使用 PHP。 接下來讓我們安裝 PHP redis 驅(qū)動:下載地址為:https://github.com/phpredis/phpredis/releases。
以下操作需要在下載的 phpredis 目錄中完成:
$ wget https://github.com/phpredis/phpredis/archive/3.1.4.tar.gz $ cd phpredis-3.1.4 # 進入 phpredis 目錄 $ /usr/local/php/bin/phpize # php安裝后的路徑 $ ./configure --with-php-config=/usr/local/php/bin/php-config $ make && make install
vi /usr/local/php/lib/php.ini
增加如下內(nèi)容:
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626" extension=redis.so
安裝完成后重啟php-fpm 或 apache。查看phpinfo信息,就能看到redis擴展。
