http://gems.ruby-china.org/ added to sources  
  
[root@bogon ~] gem install redis-dump -V
 redis-dump導出數據
[root@bogon ~] telnet 127.0.0.1 6379
Trying 127.0.0.1...

Escape character is '^]'.  
set test 11 //設置一個值  
+OK  
get test //取值  
$2  
11 
[root@bogon ~] redis-dump -u :passwd@127.0.0.1:6379 >test.json 

 

[root@bogon ~] telnet 127.0.0.1 6379 //telnet到redis 

Trying 127.0.0.1...
