日誌內容：Redis被配置為儲存資料庫快照，但它目前不能持久化到硬碟。用來修改集合資料的命令不能用。請檢視Redis日誌的詳細錯誤資訊。

redis快照被強制關閉了導致不能持久化。

首先檢視redis伺服器上的磁碟是否滿了和其對磁碟的訪問許可權是否不足。

此次報錯為磁碟空間不足。

網上搜索到的解決辦法多為 將redis的 stop-writes-on-bgsave-error值設定為no（未嘗試）

命令列修改:

127.0.0.1:6379> config set stop-writes-on-bgsave-error no

重啟redis-server

redis.conf檔案中修改如下配置：

將stop-writes-on-bgsave-error 這一配置項修改為“no”，即在伺服器磁碟出現問題時不會停止redis的寫入操作
