mysql-cluster中的sql node（主）与单独的mysql server（从）做主从复制（错误解决）

集群环境：    

    mysql-cluster 7.2.8 （mysql 5.5.27 ; ndb 7.2.8）

    192.168.55.11 mgm node (nodeid=1) 

    192.168.55.10 data node (nodeid=2)+ sql node (nodeid=4)

    192.168.55.9  data node (nodeid=3)+ sql node(nodeid=5) 

    MySQL服务器：

    192.168.55.133 mysql

    启动：# /var/lib/mysql/bin/mysqld_safe &

    关闭：# /var/lib/mysql/bin/mysqladmin shutdown

    进入数据库：#  /var/lib/mysql/bin/mysql -u root -p

    主从环境搭配：    

    主：master(sql node (nodeid=4))

    [mysqld]

    server-id = 1

    log-bin = mysql-bin

    binlog_format = row

    binlog-do-db = db_name1

    binlog-do-db = db_name2

    binlog-ignore-db = db_name3

    从：slave(mysql)

    [mysqld]

    server-id = 3

    log-bin = mysql-bin

    binlog_format = row

    binlog-do-db = db_name1

    binlog-do-db = db_name2

    binlog-ignore-db = db_name3

    55.133

    55.9

    # mysqld_safe --ndb_nodeid=5 --user=mysql --server_id=1 &

    # mysql -u mysql -p

    mysql> show master status;

    mysql> flush privileges;

    mysql> change master to master_host='192.168.55.9', master_user='slaveuser', master_password='000', master_log_file='mysql-bin.000003', master_log_pos=112;   

    mysql> start slave;

    mysql> show slave status/G;

    提示错误： Last_IO_Error: error connecting to master 'slaveuser@192.168.55.9:3306' - retry-time: 60  retries: 86400

    但是通过：# mysql -h 192.168.55.9 -u slavemysql -p 可成功登录远程9上的数据库。

              # 在55.9上 mysql> grant all on *.* toslavemysql@192.168.211.133 identified by '908'; 也已经成功授权
