今天在启动celery时报错：
[2020-12-21 14:12:48,615: ERROR/MainProcess] consumer: Cannot connect to redis://127.0.0.1:6379/1: 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 (sto │p-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.. │Trying again in 18.00 seconds... (9/100)
问题定位
网上查阅后发现是因为，把redis快照强制关闭了导致不能持久化的问题
目前发现两种解决方案：
1、通过stop-writes-on-bgsave-error值设置为no即可避免这种问题。
2、通过修改redis.conf配置文件，将stop-writes-on-bgsave-error值改为no（效果和1一样）
解决
通过redis命令行直接改：
进入redis命令行执行：config set stop-writes-on-bgsave-error no
通过修改redis.conf文件修改：
保存退出
