今天运行Django项目在redis数据库写入数据时提示如下错误：

redis.exceptions.ResponseError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

ERROR basehttp 154 "GET /image_code/cf9ccd75-d274-45c0-94a4-a83c8c189965/ HTTP/1.1" 500 89760

redis数据库写入数据时提示redis.exceptions.ResponseError错误

原因

强制关闭Redis快照导致不能持久化。

解决方案

将stop-writes-on-bgsave-error设置为no

(dj14) sky@py:~$ redis-cli

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

OK

127.0.0.1:6379>
