[[email protected] redis]# pkill -9 redis

[[email protected] ~]# cd /var/dir

[[email protected] ~]# rm -rf *

清除掉现有环境备份文件；然后启动服务器进程，添加新数据

[[email protected] redis]# ./bin/redis-server ./redis.conf

[[email protected] redis]# ./bin/redis-server ./redis6380.conf

[[email protected] redis]# ./bin/redis-server ./redis6381.conf

[[email protected] redis]# ./bin/redis-cli

127.0.0.1:6379> keys *

(empty list or set)

127.0.0.1:6379> set site www.baidu.com

OK

127.0.0.1:6379> set name yjf

OK

127.0.0.1:6379> set addr bj

OK

127.0.0.1:6379> flushall

OK

127.0.0.1:6379> get name

(nil)

此时一定要先停止服务，避免其他人有写入操作，重写aof。况且aof记录着也有flushall操作。

[[email protected] dir]# more laoyang-appendonly.aof

flushall

然后编辑一下aof生成文件。将最后危险操作flushall给dd掉。--注意记录的格式，一般是*开始，命令结尾；

[[email protected] dir]# vim laoyang-appendonly.aof

删除下面三行，保存退出

flushall

然后重启一下服务，登陆查询，如果么有，退出后，再次登陆查询

[[email protected] redis]# ./bin/redis-server ./redis.conf

[[email protected] redis]# ./bin/redis-cli

127.0.0.1:6379> get name

127.0.0.1:6379> exit
