如果是用apt-get或是yum install安裝的redis，可以直接透過下面的指令停止/啟動/重新啟動redis
/etc/init.d/redis-server stop /etc/init.d/redis-server start /etc/init.d/redis-server restart
注意：使用/etc/ init.d/redis-server start 方法啟動redis,那麼在那個目錄下啟動redis,那麼redis的備份檔就在那個目錄下。
如在/user/bin/redis/目錄下輸入指令/etc/init.d/redis-server start ，那麼redis備份檔就在/user/bin/redis/dump.rdb
如果是透過原始碼安裝的redis，則可以透過redis的客戶端程式redis-cli的shutdown指令來重啟redis
redis-cli -h 127.0.0.1 -p 6379 shutdown
如果上述方式都沒有成功停止redis，則可以使用終極武器kill -9
