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;
+------------------+----------+------------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

mysql> flush privileges;

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
