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

代码如下:

	
	[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

代码如下:

[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

代码如下:

	
	[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
