Migrating Redis databases to cloud databases

You can migrate Redis databases to Selectel cloud databases.

  1. Connect to Redis. If you use a password, specify it in an environment variable:

    export REDISDUMPGO_AUTH=<password>

    Specify <password> — password of the source cluster user.

  2. Create a dump of the source cluster using the utility redis_dump_go:

    redis-dump-go \
          -host <host> \
          -port <port> \
          > redis_backup.txt

    Specify:

    • <host> — The IP address or DNS name of the source cluster master host;
    • <port> — port.

  3. Restore the dump to the receiving cluster:

    redis-cli \
            -a <password> \
            -h <host> \
            -p <port> \
            --tls \
            --cacert <cacert> \
            --pipe \
            < redis_backup.txt

    Specify:

    • <password> — password of the receiving cluster user;
    • <host> — The IP address or DNS name of the master host of the receiving cluster;
    • <port> — port;
    • <cacert> — root certificate.
