{db :7, key : love , ttl :-1, type : string , value : peihy , size :5}

{db :7, key : chenfeng , ttl :-1, type : string , value : dsf , size :3}

二. 使用:

全库备份例子:

#cd redis-dump/bin

#./redis-dump -u 127.0.0.1   /root/shell/20180928/db_all.json

只备份 redis 某个库的例子:

首先往 10 号库里写点数据:

#redis-cli

127.0.0.1:6379[1] select 10

OK

127.0.0.1:6379[10] set China World

OK

127.0.0.1:6379[10] set love chenfeng

OK

127.0.0.1:6379[10] set fuck America

OK

只备份 10 号库:

#./redis-dump -u 127.0.0.1 -d 10   /root/shell/20180928/db_10.json

查看内容：

[root@alpha-mongo-140-52 ~/shell/20180928/redis-dump/bin]#cat /root/shell/20180928/db_10.json

{db :10, key : fuck , ttl :-1, type : string , value : America , size :7}

{db :10, key : love , ttl :-1, type : string , value : chenfeng , size :8}

{db :10, key : China , ttl :-1, type : string , value : World , size :5}
