在公司工作之余看了MySQL的Master-Slave设置,大致的意思和流程已然懂了,但从未实践过。今天有时间实践一下,手头有两台Win7机器,就凑合着用吧!! 首先设定是关系A为Master,B为Slave.(两台机器的Mysql都是5.0,但不同) 设置A 的my.ini server-id = 1log-

在公司工作之余看了MySQL的Master-Slave设置,大致的意思和流程已然懂了,但从未实践过。今天有时间实践一下,手头有两台Win7机器,就凑合着用吧!!

首先设定是关系A为Master,B为Slave.(两台机器的Mysql都是5.0+,但不同)

设置A 的my.ini

server-id = 1
log-bin=mysql-bin
binlog_do_db=test1
binlog_ignore_db=mysql
innodb_flush_log_at_trx_commit=1
sync_binlog=1
binlog_checksum=none

说明:

server-id = 1 #机器ID
log-bin=mysql-bin #开启二进制日志
binlog_do_db=test1 #要同步的数据库
binlog_ignore_db=mysql #忽略mysql数据库
sync_binlog=1 #及时刷新写入二进制日志

binlog_checksum=none #版本不同且A大于5.6所以要设置一下

在A上创建test1数据库 和tab表

在Master上创建slave用户

grant all privileges on *.* to slave@'%' identified by 'slave';

这是个超级用户啊,哈哈

A即Master基本配置完毕

开始配置B-Slave

设置B的my.ini

log-bin=mysql-bin
binlog_do_db=test1
binlog_ignore_db=mysql
说明同上

并在B上创建和A完全相同的test1数据库 和tab表

至此配置都已完成,下面开始寻找要同步的二进制日志的同步点

在A输入

mysql>show master status\G;
*************************** 1. row ***************************
             File: mysql-bin.000053
         Position: 606
     Binlog_Do_DB: test1
 Binlog_Ignore_DB: mysql
Executed_Gtid_Set:
即test1数据库的二进制日志是mysql-bin.000053 位置是606

在B上输入

change master to master_host='A的ip',master_user='slave',master_password='slave',master_log_file='mysql-bin.000053',master_log_pos=606;
mysql> show slave status\G;
*************************** 1. row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: 10.209.78.13
                  Master_User: slave
                  Master_Port: 3306
                Connect_Retry: 30
              Master_Log_File: mysql-bin.000053
          Read_Master_Log_Pos: 333
               Relay_Log_File: Lee-PC-relay-bin.000002
                Relay_Log_Pos: 492
        Relay_Master_Log_File: mysql-bin.000053
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes
              Replicate_Do_DB: test1
          Replicate_Ignore_DB: mysql
           Replicate_Do_Table:

如果看到了
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
说明你成功了。

那就赶紧测试一下吧。

在A上insert一条数据,看看B上传过来了没

教程至此完毕

说明:若在B上show  slave status\G;时出现connecting to master时 原因可能是

  1. 密码错误
  2. A的3306端口不通
  3. 等一切B机器连不上A机器的问题
