redis导入rdb文件的方法:
在源实例生成aof数据,代码命令如下:
# 清空上文目标实例全部数据
[root@172.20.0.1 ~]# redis-cli -h 172.20.0.2 -a password flushall
OK
# 源实例开启aof功能,将在dir目录下生成appendonly.aof文件
[root@172.20.0.1 ~]# redis-cli -h 172.20.0.1 -a password config set appendonly yes
OK
在目标实例导入aof数据,代码命令如下:
# 假设appendonly.aof就在当前路径下
[root@172.20.0.1 ~]# redis-cli -h 172.20.0.2 -a password --pipe < appendonly.aof
