主服务器的ip是192.168.19.139 副服务器的ip是192.168.19.142
1.主服务器配置
(1)修改my.cnf(注意使用root)
vim /etc/my.cnf
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
log-bin=mysqlbin-log
server_id=1
basedir=/home/mysql
user=mysql
datadir=/home/mysql/data
port=3306
innodb_flush_log_at_trx_commit=1
sync_binlog=1
log-slave-updates
(2)进入mysql安装目录下的bin，启动mysql
cd /home/mysql/bin 2 ./mysqld
(3)重开启mysql客户端，进入mysql安装目录下的bin，授权副服务器主从复制，用mysqld的好处是可以查看错误。
./mysql -uroot -p 2 mysql> grant replication slave on *.* to [email protected] identified by '123';
(4)显示主服务器状态
mysql> show master status;
+---------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+---------------------+----------+--------------+------------------+-------------------+
| mysqlbin-log.000019 | 1290 | | | |
+---------------------+----------+--------------+------------------+-------------------+
2.副服务器配置
(1)修改my.cnf(注意使用root)
vim /etc/my.cnf
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLE
user=mysql
server_id = 2
replicate-do-db = sbfxd
master-info-file = master.info
relay-log = relay-relay-bin
relay-log-index = relay-relay-bin.index
relay-log-info-file=relay-relay-log.info
(2)进入mysql安装目录下的bin，启动mysql
cd /home/mysql/bin 2 ./mysqld
(3)重开启mysql客户端，进入mysql安装目录下的bin，设置slave属性并开始服务
./mysql -uroot -p
mysql> change master to master_host='192.168.19.139',master_port= 3306, master_log_file='mysqlbin-log.000019', master_log_pos= 1290, master_bind='', master_user='test',master_password='123';
mysql> start slave;
(4)显示副服务器的状态

出现两个yes表示slave可以跑了
3.注意事项：
(1)楼主的虚拟机是通过克隆产生的，所以不需要对mysql进行备份，然后在副服务器上恢复，这步对于数据库极其重要，否则就会出现如下错误:
2016-08-17T03:11:27.579193Z 5 [ERROR] Slave SQL for channel '': Error executing row event: 'Table 'sbfxd.sbtable' doesn't exist', Error_code: 1146
2 2016-08-17T03:11:27.584268Z 5 [Warning] Slave: Table 'sbfxd.sbtable' doesn't exist Error_code: 1146
(2)如果将主服务器的属性配错了需要stop slave，然后设置好之后start slave
