| First, create a dump on server A. | |
| A$ redis-cli | |
| 127.0.0.1:6379> CONFIG GET dir | |
| 1) "dir" | |
| 2) "/var/lib/redis/" | |
| 127.0.0.1:6379> SAVE | |
| OK | |
| This ensures dump.rdb is completely up-to-date, and shows us where it is stored (/var/lib/redis/dump.rdb in this case). dump.rdb is also periodically written to disk automatically. | |
| Next, copy it to server B: | |
| A$ scp /var/lib/redis/dump.rdb myuser@B:/tmp/dump.rdb | |
| Stop the Redis server on B, copy dump.rdb (ensuring permissions are the same as before), then start. | |
| B$ sudo service redis-server stop | |
| B$ sudo cp /tmp/dump.rdb /var/lib/redis/dump.rdb | |
| B$ sudo chown redis: /var/lib/redis/dump.rdb | |
| B$ sudo service redis-server start | |
| The version of Redis on B must be greater or equal than that of A, or you may hit compatibility issues. |
rdb command is available by installing rdb-tools
