redis的備份和還原，借助了第三方的工具，redis-dump

1、安裝redis-dump

復制代碼代碼如下:

[root@localhost tank]# yum install ruby rubygems ruby-devel   //安裝rubygems 以及相關包  
[root@localhost tank]# gem sources -a http://ruby.taobao.org/   //源，加入淘寶，外面的源不能訪問  
http://ruby.taobao.org/ added to sources  
[root@localhost tank]# gem install redis-dump -V   //安裝redis-dump  

2、redis-dump導出數(shù)據(jù)

復制代碼代碼如下:

[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 //設置一個值
+OK
get test //取值
$2
11

[root@localhost tank]# redis-dump -u 127.0.0.1:6379 >test.json //導出數(shù)據(jù)

3、redis-load還原數(shù)據(jù)

復制代碼代碼如下:

[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 //請空所有數(shù)據(jù)  
+OK  
keys * //查看已清空  
*0  
  
[root@localhost tank]# < test.json redis-load //導入數(shù)據(jù)  
  
[root@localhost tank]# telnet 127.0.0.1 6379  
Trying 127.0.0.1...  
Connected to 127.0.0.1.  
Escape character is '^]'.  
keys * //已導入成功  
*1  
$4  
test
