redis安装备份导入数据-集群

安装

yum install epel-release

yum install redis


##开启远程
vim  /etc/redis.conf  
bind  ip  #本机ip 


##systemctl  start  redis 
##redis-cli -h 192.168.190.139

实验成功的aof方式

#实例1,源实例开启aof功能，将在dir目录下生成appendonly.aof文件
config set appendonly yes
BGSAVE
save 

#获取appendonly.aof 文件后转移至实例2 导入
redis-cli   -h  192.168.2.141 --pipe  < appendonly.aof

#检查数据

源实例db0迁移至目标实例db1

未测试

#!/bin/bash
redis-cli -h x.1 -p 6379 -a password -n 0 keys "*" | while read key
do
    redis-cli -h x.1 -p 6379 -a password -n 0 --raw dump $key | perl -pe 'chomp if eof' | redis-cli -h x.2 -p 6379 -a password -n 1 -x restore $key 0
    echo "migrate key $key"
done

redis-dump工具

未测试

yum install ruby rubygems ruby-devel -y

gem sources -a http://ruby.taobao.org
gem sources --add http://gems.ruby-china.org/ --remove http://rubygems.org/
gem install redis-dump -V

#导出数据
redis-dump -u :password@172.20.0.1:6379 > 172.20.0.1.json


#导入数据
