如何将redis改为持久化

Question

我使用redis。

我希望数据库能够持久化，但是当我终止我的进程时，我注意到数据没有恢复。

在示例中，我有100个键和值。我的进程在id = 26060上运行。当我这样做时：

kill -9 26060

再次运行redis-server，所有密钥都丢失了。

我在redis.conf中查看相关定义，但找不到任何内容。

如何让它持久？

关于您的测试，如果您希望对其进行快照，则应该等待5分钟才能终止该进程。

这是Redis（2.8 - 3.0）的默认配置：

################################ SNAPSHOTTING  ################################
#
# Save the DB on disk:
#
#   save <seconds> <changes>
#
#   Will save the DB if both the given number of seconds and the given
#   number of write operations against the DB occurred.
#
#   In the example below the behaviour will be to save:
#   after 900 sec (15 min) if at least 1 key changed
#   after 300 sec (5 min) if at least 10 keys changed
#   after 60 sec if at least 10000 keys changed
#
#   Note: you can disable saving completely by commenting out all "save" lines.
#
#   It is also possible to remove all the previously configured save
#   points by adding a save directive with a single empty string argument
#   like in the following example:
#
#   save ""

save 900 1
save 300 10
save 60 10000

关于持久性的一切都在documentation

中解释

将保存数据的文件由以下配置选项定义：

# The filename where to dump the DB
dbfilename dump.rdb

# For default save/load DB in/from the working directory
# Note that you must specify a directory not a file name.
dir /var/lib/redis/
