开始在 PHP 中使用 Redis 前, 咱们须要确保已经安装了 redis 服务及 PHP redis 驱动,且你的机器上能正常使用 PHP。 接下来让咱们安装 PHP redis 驱动:下载地址为:https://github.com/phpredis/phpredis/releases。php
如下操做须要在下载的 phpredis 目录中完成:html
$ 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
若是你是 PHP7 版本,则须要下载指定分支:git
git clone -b php7 https://github.com/phpredis/phpredis.git
vi /usr/local/php/lib/php.ini
增长以下内容:github
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20090626" extension=redis.so
安装完成后重启php-fpm 或 apache。查看phpinfo信息,就能看到redis扩展。redis
<?php //链接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; //查看服务是否运行 echo "Server is running: " . $redis->ping(); ?>
执行脚本,输出结果为:sql
Connection to server sucessfully Server is running: PONG
<?php //链接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; //设置 redis 字符串数据 $redis->set("tutorial-name", "Redis tutorial"); // 获取存储的数据并输出 echo "Stored string in redis:: " . $redis->get("tutorial-name"); ?>
执行脚本,输出结果为:apache
Connection to server sucessfully Stored string in redis:: Redis tutorial
<?php //链接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; //存储数据到列表中 $redis->lpush("tutorial-list", "Redis"); $redis->lpush("tutorial-list", "Mongodb"); $redis->lpush("tutorial-list", "Mysql"); // 获取存储的数据并输出 $arList = $redis->lrange("tutorial-list", 0 ,5); echo "Stored string in redis"; print_r($arList); ?>
执行脚本,输出结果为:php7
Connection to server sucessfully Stored string in redis Redis Mongodb Mysql
<?php //链接本地的 Redis 服务 $redis = new Redis(); $redis->connect('127.0.0.1', 6379); echo "Connection to server sucessfully"; // 获取数据并输出 $arList = $redis->keys("*"); echo "Stored keys in redis:: "; print_r($arList); ?>
执行脚本,输出结果为:php-fpm
Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list
