安装依赖包

yum -y install automake libtool autoconf bzip2 unzip

下载和安装redis-migrate-tool

unzip redis-migrate-tool-master.zip
cd redis-migrate-tool-master
autoreconf -fvi
./configure 
make
vim /etc/profile.d/redis.sh
export PATH=$PATH:/ane/redis-migrate-tool-master/src
chmod +x /etc/profile.d/redis.sh 
source /etc/profile.d/redis.sh

导出

redis-migrate-tool -c redis-migrate-tool-master/rmt.conf -o log.txt -d
tail -500f log.txt 

将rdb文件拷贝到另一台服务器并在另一台服务器上安装redis-migrate-tool

导入

vim redis-migrate-tool-master/rmt.conf
