Redis 关闭持久化及关闭持久化后正确删除持久化之前的数据

去掉持久化

首先要确保你启动Redis加载的配置文件的路径是正确的

修改配置文件 redis.windows-service.conf

找到以下内容并设置 若无请添加

#save 900 1#save 300 10#save 60 10000

appendonly=no

save ""

如果之前存储了持久化的数据，发现删除了后重启服务数据还会恢复 来到Redis目录下删除dump.rdb即可。 dump.rdb 是redis 启动的时候会加载的数据文件。

在Redis中提供了两种 持久化功能

1. RDB持久化：
该机制是指在指定的时间间隔内将内存中的数据集快照写入磁盘。
这个机制是redis的默认持久化机制，在redis.conf配置文件当中，有

################################ 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 changedsave 900 1save 300 10save 60 10000该机制默认15分钟有一次修改，6分钟内有10次修改，1分钟内有10000次修改，将会将快照数据集集中写入磁盘（即dump.rdb文件）下面两个配置，设置了持久化文件的位置和文件名

# The filename where to dump the DBdbfilename dump.rdb# For default save/load DB in/from the working directory# Note that you must specify a directory not a file name.dir ./

2. AOF持久化:
该机制将以日志的形式记录服务器所处理的每一个写操作，在Redis服务器启动之初会读取该文件来重新构建数据库，以保证启动后数据库中的数据是完整的。
通过在redis.conf配置文件中将
appendonly no 改为yes就会开启AOF持久化功能，默认是no

############################## APPEND ONLY MODE ################################ By default Redis asynchronously dumps the dataset on disk. If you can live# with the idea that the latest records will be lost if something like a crash# happens this is the preferred way to run Redis. If instead you care a lot# about your data and don't want to that a single record can get lost you should# enable the append only mode: when this mode is enabled Redis will append# every write operation received in the file appendonly.log. This file will# be read on startup in order to rebuild the full dataset in memory.## Note that you can have both the async dumps and the append only file if you# like (you have to comment the "save" statements above to disable the dumps).# Still if append only mode is enabled Redis will load the data from the# log file at startup ignoring the dump.rdb file.## The name of the append only file is "appendonly.log"## IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append# log file in background when it gets too big.appendonly no
