phpredis扩展提供了一个与Redis键值存储通信的API。
wget https://pecl.php.net/get/redis-5.3.4.tgz
当然也可以使用当前目录下的redis-5.3.4.tgz
- pecl redis扩展地址：https://pecl.php.net/package/redis
- redis github地址：https://github.com/phpredis/phpredis
tar xzf redis-5.3.4.tgz
$ cd redis-5.3.4
$ export PHP_HOME=you_php_home
$ $PHP_HOME/php/bin/phpize
$ ./configure --with-php-config=$PHP_HOME/php/bin/php-config
$ make -j12
执行完了之后，modules目录会产出xdiff.so
$ ls modules/
redis.so
在php.ini文件末尾增加如下内容：
[redis]
extension="redis.so"
将编译好的redis.so拷贝到php.ini文件中extension_dir配置的位置。 比如我的php.ini中extension_dir配置如下：
extension_dir="/home/work/php/ext"
则只需要将编译好的redis.so拷贝到/home/work/php/ext目录
cp modules/redis.so /home/work/php/ext
$ cd $PHP_HOME
$ php/bin/php --ri redis

如果执行php/bin/php --ri redis命令可以输出上述信息，那么说明redis扩展已经安装成功了。
<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set('mykey', 'myval');
$val = $redis->get('mykey');
