2、将备份文件恢复到redis集群B下。
1、备份redis集群A
[root@admin12 redis-3.0.6]# redis-cli -h localhost -p 6380 save OK [root@admin12 redis-3.0.6]# redis-cli -h localhost -p 6381 save OK [root@admin12 redis-3.0.6]# redis-cli -h localhost -p 6382 save OK
2、将备份出的文件拷贝出来
[root@admin12 ~]# cp /var/lib/redis/6380/dump.rdb ./dump_6380.rdb [root@admin12 ~]# cp /var/lib/redis/6381/dump.rdb ./dump_6381.rdb [root@admin12 ~]# cp /var/lib/redis/7382/dump.rdb ./dump_6382.rdb
3、关闭redis集群B
[root@localhost ~]# redis-cli -p 6380 shutdown [root@localhost ~]# redis-cli -p 6381 shutdown [root@localhost ~]# redis-cli -p 6382 shutdown
4、将备份文件复制到redis集群B下
/var/lib/redis/6380/dump.rdb /var/lib/redis/6381/dump.rdb /var/lib/redis/6382/dump.rdb
5、重新启动redis集群B
[root@localhost redis]# cd /etc/redis [root@localhost redis]# service redis_6380 start Starting Redis server... [root@localhost redis]# service redis_6381 start Starting Redis server... [root@localhost redis]# service redis_6382 start Starting Redis server...
