mysql无法在mysql Ver 14.14 Distrib 5.6.41版本上的从属系统上启动（mysql master可以复制）？

Question

    My Configuration:
    server-id = 2
    master-host=192.1.1.12
    master-connect-retry=60
    master-user=root
    master-password=root123
    replicate-do-db=testdatabase
    relay-log = /var/lib/mysql/mysql-relay-bin
    relay-log-index = /var/lib/mysql/mysql-relay-bin.index
    log-error = /var/lib/mysql/mysql.err
    master-info-file = /var/lib/mysql/mysql-master.info
    relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
    log-bin = /var/lib/mysql/mysql-bin

   

Output:
