Redis恢复数据

1、 获取redis备份目录

127.0.0.1:6379> CONFIG GET dir
1) "dir"
2) "D:\\software\\Redis"
127.0.0.1:6379>

以上命令 CONFIG GET dir 输出的 redis 备份目录为 /usr/local/redis/bin。

2、 停止redis服务

src/redis-cli -p 6379 shutdown

src是redis安装目录

3、拷贝redis备份文件（dump.rdb）到 /usr/local/redis/bin目录下

4、重新启动redis服务

linux
src/redis-server redis.conf
windows
src/redis-server redis.windows.conf

5、查看是否redis恢复数据

$ src/redis-cli
127.0.0.1:6379> keys *
 1) "k1"
 2) "k2"
 3) "k3"
 4) "k4"
 5) "k5"
