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
- 密码错误
- A的3306端口不通
- 等一切B机器连不上A机器的问题

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
