一、安装 redis

可参见米扑博客：Centos Redis 安装配置和启动脚本、Mac OS X 安装 Redis

1）下载最新版redis
wget http://download.redis.io/redis-stable.tar.gz
解压编译
tar zxvf redis-2.4.17.tar.gz
cd redis-2.4.17
make
make PREFIX=/usr/local/redis install

2）配置 redis
mkdir /etc/redis
cp redis.conf  /etc/redis/redis.conf
mkdir /var/lib/redis
拷贝命令文件
cp redis-server /usr/local/bin/
cp redis-cli /usr/local/bin/

3）修改配置信息
# 然后新建目录，存放配置文件
mkdir /etc/redis
mkdir /var/redis
mkdir /var/redis/log
mkdir /var/redis/run
mkdir /var/redis/6379
# 在redis解压根目录中找到配置文件模板，复制到如下位置。
cp redis.conf /etc/redis/6379.conf
# 通过vim命令修改
daemonize yes  #介个是设置服务在后台运行
pidfile /var/redis/run/redis_6379.pid
logfile /var/redis/log/redis_6379.log
dir /var/redis/6379

4）运行redis
redis-server /etc/redis/6379.conf

二、安装PHP扩展 phpredis

GitHub： https://github.com/phpredis/phpredis

GitHub： https://github.com/phpredis/phpredis/tree/php7 （PHP7 redis 扩展）

phpredis-php7.zip ： https://github.com/phpredis/phpredis/archive/php7.zip

切换分支：

git clone  https://github.com/phpredis/phpredis.git

git checkout -b php7 origin/php7
检查PHP扩展
/usr/local/php7/bin/phpize
建立编译连接
./configure --with-php-config=/usr/local/php7/bin/php-config
make
make test
安装
make install
检查so文件
ls -l /usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/
修改php.ini
vi /usr/local/php7/etc/php.ini
添加：extension="redis.so"

三、重启 nginx
sudo service nginx restart
sudo /etc/init.d/php-fpm restart

四、测试
make test
附加扩展 pdo_mysql

pdo_mysql 扩展

cd /home/data/tool-server/LNMP/php-7.0.13/ext/pdo_mysql/
./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/bin/mysql_config
make && make install

安装结果：
