redis中使用redis-dump导出、导入、还原数据实例

redis的备份和还原，借助了第三方的工具，redis-dump

1、安装redis-dump

[root@localhost tank]# yum install ruby rubygems ruby-devel   //安装rubygems 以及相关包 
[root@localhost tank]# gem sources -a http://ruby.taobao.org/   //源，加入淘宝，外面的源不能访问 
http://ruby.taobao.org/ added to sources 
[root@localhost tank]# gem install redis-dump -v   //安装redis-dump 

2、redis-dump导出数据

[root@localhost tank]# telnet 127.0.0.1 6379 //telnet到redis 
trying 127.0.0.1... 
connected to 127.0.0.1. 
escape character is '^]'. 
set test 11 //设置一个值 
+ok 
get test //取值 
$2 
11 
 
[root@localhost tank]# redis-dump -u 127.0.0.1:6379 >test.json //导出数据 

3、redis-load还原数据

[root@localhost tank]# telnet 127.0.0.1 6379 //telnet到redis 
trying 127.0.0.1... 
connected to 127.0.0.1. 
escape character is '^]'. 
flushall //请空所有数据 
+ok 
keys * //查看已清空 
*0 
 
[root@localhost tank]# < test.json redis-load //导入数据 
 
[root@localhost tank]# telnet 127.0.0.1 6379 
trying 127.0.0.1... 
connected to 127.0.0.1. 
escape character is '^]'. 
keys * //已导入成功 
*1 
$4 
test
