重啟redis，發現一直報：Waiting for Redis to shutdown
service redis_6379 restart Stopping ... OK (error) NOAUTH Authentication required. Waiting for Redis to shutdown ... Waiting for Redis to shutdown ... Waiting for Redis to shutdown ... Waiting for Redis to shutdown ... Waiting for Redis to shutdown ... Waiting for Redis to shutdown ... Waiting for Redis to shutdown ...
因為配置了密碼驗證，而在restart的時候並沒有配置密碼。
解決方法：
1.修改redis服務腳本，加入如下所示的信息即可：
vi /etc/init.d/redis $CLIEXEC -a "password" -p $REDISPORT shutdown
