Question

我通过在redis-db中调用BGSAVE命令开始保存redis-cli快照。

它已经开始运行但我在日志中不断收到这些错误

看起来redis BGSAVE命令无限期地运行。如何制止这一点。

我也尝试通过ps -aux| grep redis命令检查进程pid。

13196 pts/11   S+     0:00 grep --color=auto redis
30853 ?        Ssl  1292:57 /usr/bin/redis-server *:6379

没有杀人的过程。

编辑：这些是redis文件夹和dump.rdb文件的权限

f: /var/lib/redis
drwxr-xr-x root  root  /
drwxr-xr-x root  root  var
drwxr-xr-x root  root  lib
drwxr-xr-x redis redis redis

f: /var/lib/redis/dump.rdb
drwxr-xr-x root  root  /
drwxr-xr-x root  root  var
drwxr-xr-x root  root  lib
drwxr-xr-x redis redis redis
-rw-rw-rw- redis redis dump.rdb

EDIT2：得到了答案。问题是以某种方式改变了配置参数。 dbfilename和dir值已更改。

通过CONFIG SET命令将这些值设置为原始值，现在它正常工作。添加以防有人有同样的问题。

但问题是他们是如何改变的。这是否发生在其他人身上？

您可以尝试修复文件权限错误（默认保存位置是否存在，redis是否有权写入？）或者您可以使用以下命令禁用保存：

config set save ""

中止BGSAVE已经在进行中
