1、第一步自然是去github下載原始碼了，記得加上引數 --no-check-certificate，不然https校驗會出錯

wget https://github.com/phpredis/phpredis/archive/develop.zip --no-check-certificate

2、解壓下載好的包，

unzip develop
cd phpredis-develop/

3、配置和編譯，注意修改為php的安裝目錄位置

~/php/bin/phpize 
./configure --with-php-config=~/php/bin/php-config 
make && make install

正常情況下應該就編輯好so檔案，並放到php的擴充套件目錄下了，但是我在編譯時出錯了：

.libs/redis_cluster.o:(.data.rel.local+0x0): multiple definition of `arginfo_kscan'
.libs/redis.o:(.data.rel.local+0xa0): first defined here
.libs/redis_cluster.o:(.data.rel.local+0xe0): multiple definition of `arginfo_scan'

返回檢視php/ext目錄，有redis.so擴充套件了，重啟php-fpm再看看phpinfo()，就有redis資訊了：

Redis Support	enabled
Redis Version	2.2.5

$redis = new Redis();
$conn = $redis->connect('127.0.0.1',6379);
var_dump($redis->info());
