redis的備份和還原，借助了第三方的工具，redis-dump
1、安裝redis-dump
復(fù)制代碼代碼如下:
[root@localhost tank]# yum install ruby rubygems ruby-devel //安裝rubygems 以及相關(guān)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(dǎo)出數(shù)據(jù)
復(fù)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(shè)置一個(gè)值
+OK
get test //取值
$2
11
[root@localhost tank]# redis-dump -u 127.0.0.1:6379 >test.json //導(dǎo)出數(shù)據(jù)
3、redis-load還原數(shù)據(jù)
復(fù)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(qǐng)空所有數(shù)據(jù)
+OK
keys * //查看已清空
*0
[root@localhost tank]# < test.json redis-load //導(dǎo)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(dǎo)入成功
*1
$4
test
