redis中使用redis-dump導出、導入、還原數據實例

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導出數據

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 //導出數據 

3、redis-load還原數據

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 //請空所有數據 
+OK 
keys * //查看已清空 
*0 
 
[root@localhost tank]# < test.json redis-load //導入數據 
 
[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
