        healthcheck retry delay (default 1m0s)

  -vreplication_healthcheck_topology_refresh duration

        refresh interval for re-reading the topology (default 30s)

  -vreplication_heartbeat_update_interval int

        Frequency (in seconds, default 1, max 60) at which the time_updated column of a vreplication stream when idling (default 1)

  -vreplication_replica_lag_tolerance duration

        Replica lag threshold duration: once lag is below this we switch from copy phase to the replication (streaming) phase (default 1m0s)

  -vreplication_retry_delay duration

        delay before retrying a failed binlog connection (default 5s)

  -vreplication_store_compressed_gtid

        Store compressed gtids in the pos column of _vt.vreplication

  -vreplication_tablet_type string

        comma separated list of tablet types used as a source (default "PRIMARY,REPLICA")

  -vstream_dynamic_packet_size

        Enable dynamic packet sizing for VReplication. This will adjust the packet size during replication to improve performance. (default true)

  -vstream_packet_size int

        Suggested packet size for VReplication streamer. This is used only as a recommendation. The actual packet size may be more or less than this amount. (default 250000)

  -vtctld_addr string

        address of a vtctld instance

  -vtgate_protocol string

        how to talk to vtgate (default "grpc")

  -vttablet_skip_buildinfo_tags string

        comma-separated list of buildinfo tags to skip from merging with -init_tags. each tag is either an exact match or a regular expression of the form '/regexp/'. (default "/.*/")

  -wait_for_backup_interval duration

        (init restore parameter) if this is greater than 0, instead of starting up empty when no backups are found, keep checking at this interval for a backup to appear

  -watch_replication_stream

        When enabled, vttablet will stream the MySQL replication stream from the local server, and use it to update schema when it sees a DDL.

  -xbstream_restore_flags string

        flags to pass to xbstream command during restore. These should be space separated and will be added to the end of the command. These need to match the ones used for backup e.g. --compress / --decompress, --encrypt / --decrypt

  -xtrabackup_backup_flags string

        flags to pass to backup command. These should be space separated and will be added to the end of the command

  -xtrabackup_prepare_flags string

        flags to pass to prepare command. These should be space separated and will be added to the end of the command

  -xtrabackup_root_path string

        directory location of the xtrabackup and xbstream executables, e.g., /usr/bin

  -xtrabackup_stream_mode string

        which mode to use if streaming, valid values are tar and xbstream (default "tar")

  -xtrabackup_stripe_block_size uint

        Size in bytes of each block that gets sent to a given stripe before rotating to the next stripe (default 102400)

  -xtrabackup_stripes uint

        If greater than 0, use data striping across this many destination files to parallelize data transfer and decompression

  -xtrabackup_user string

        User that xtrabackup will use to connect to the database server. This user must have all necessary privileges. For details, please refer to xtrabackup documentation.

Şöyle yaparız. Burada -init_tablet_type replica seçeneğiyle iki tane replica başlatılıyor. Kendi veri tabanına app,dba ve replication user olarak başlanıyor. Üçü için de kullanıcı ismi "vtuser" şifre ise "pass"
