redis的备份和还原，借助了第三方的工具，redis-dump
1、安装redis-dump
[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
[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 '^]'. keys * //已导入成功 *1 $4 test
