root     108782      1  0 13:47 ?        00:00:00 ./redis-server 127.0.0.1:6379

3：[root@]# php -m | grep redis
redis

vim /usr/local/php/etc/php.ini

原内容如下：
1359 session.save_handler = files
1360 

更改为：
1359 session.save_handler = redis
1360 session.save_path = "tcp://127.0.0.1:6379"

如果有密码：
1359 session.save_handler = redis
1360 session.save_path = "tcp://127.0.0.1:6379?auth=authpwd"

/etc/init.d/php-fpm restart
