edis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

[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 "^]".
