mysql5.6 — mysql5.7 GTID模式下多源复制之实践案例
发布时间：2022-03-28 13:54:04 所属栏目：MySql教程 来源：互联网
导读：背景说明：公司有多个mysql实例，单实例多个数据库，而且版本还是5.6,这给数据查询分析增加了不少繁琐的事情。所以推荐使用mysql5.6的实例多源复制到mysql5.7实例下方便数据的查询、分析以及权限的管理 环境说明：10.89.3.224 mysql5.6.39 master1 10.89.3.2

背景说明：公司有多个mysql实例，单实例多个数据库，而且版本还是5.6,这给数据查询分析增加了不少繁琐的事情。所以推荐使用mysql5.6的实例多源复制到mysql5.7实例下方便数据的查询、分析以及权限的管理 环境说明：10.89.3.224 mysql5.6.39 master1 10.89.3.225 mysql5.6.39 master2 10.89.3.222 mysql5.7.21 slave OS:centos 7.4 mysql_port:3309 操作步骤 1、安装mysql5.6 mysql5.7 详细过程不再重复、如有疑问欢迎参考我的博客 http://blog.itpub.net/29987453/viewspace-2149405/ 2、配置mysql master01配置 1)配置10.89.3.224 mysql5.6.39 master1 ##在一个复制组内的serverid必须不一样 server-id = 123 ##gtid 开启gtid mysql5.6支持 gtid_mode=on ##强制事务一致性，保证事务的安全 enforce-gtid-consistency=on ##在从库上记录从主库传过来的日志数据 log-slave-updates=1 ##开启binlog 必须的 log_bin = master01-binlog ##强烈建议设置row模式 binlog_format = row ##binlog保存的日期 expire_logs_days = 30 #relay log在从服务器中记录从主服务器传过来的日志数据 skip_slave_start=1 ###设置master-info和relay-log 存放在table中 master-info-repository = TABLE relay-log-info-repository = TABLE #指定复制的数据库 replicate-do-db=roket1,roket2 ##指定忽略的数据库(不需要复制的库) replicate-ignore- db=mysql,information_schema,performance_schema,test 2)配置完之后重启mysql server service mysqld restart 3)登录数据库，创建主从同步账号 grant replication slave on *.* to 'repl'@'10.89.3.222' identified by '123456'; flush privileges; 4)重置binlog日志 reset master; Query OK, 0 rows affected (0.01 sec) (root@localhost:mysql.sock) [(none)]>show binary logs; +------------------------+-----------+ | Log_name | File_size | +------------------------+-----------+ | master01-binlog.000001 | 151 | +------------------------+-----------+ 3、配置mysql master03配置 1)配置10.89.3.225 mysql5.6.39 master2 ##在一个复制组内的serverid必须不一样 server-id = 234 ##gtid 开启gtid mysql5.6支持 gtid_mode=on ##强制事务一致性，保证事务的安全 enforce-gtid-consistency=on ##在从库上记录从主库传过来的日志数据 log-slave-updates=1 ##开启binlog 必须的 log_bin = master01-binlog ##强烈建议设置row模式 binlog_format = row ##binlog保存的日期 expire_logs_days = 30 #relay log在从服务器中记录从主服务器传过来的日志数据 skip_slave_start=1 ###设置master-info和relay-log 存放在table中 master-info-repository = TABLE relay-log-info-repository = TABLE #指定复制的数据库 replicate-do-db=maya1,maya2 ##指定忽略的数据库(不需要复制的库) replicate-ignore- db=mysql,information_schema,performance_schema,test 2)配置完之后重启mysql server service mysqld restart 3)登录数据库，创建主从同步账号 grant replication slave on *.* to 'repl'@'10.89.3.222' identified by '123456'; flush privileges; 4)重置binlog日志 reset master; Query OK, 0 rows affected (0.01 sec) (root@localhost:mysql.sock) [(none)]>show binary logs; +------------------------+-----------+ | Log_name | File_size | +------------------------+-----------+ | master01-binlog.000001 | 151 | +————————————+-----------+ 4、配置slave数据库 1）配置配置10.89.3.222 mysql5.7.21 slave ##在一个复制组内的serverid必须不一样 server-id = 234 gtid_mode=on ##强制事务一致性，保证事务的安全 enforce-gtid-consistency=on ##在从库上记录从主库传过来的日志数据 log-slave-updates=1 ##开启binlog 必须的 log_bin = master01-binlog ##强烈建议设置row模式 binlog_format = row ##binlog保存的日期 expire_logs_days = 30 #relay log在从服务器中记录从主服务器传过来的日志数据 skip_slave_start=1 ###设置master-info和relay-log 存放在table中 master-info-repository = TABLE relay-log-info-repository = TABLE #配置只读数据库 read_only=on 4)重置binlog日志 (root@localhost:mysql.sock) [(none)]>reset master; Query OK, 0 rows affected (0.02 sec) (root@localhost:mysql.sock) [(none)]>show binary logs; +---------------------+-----------+ | Log_name | File_size | +---------------------+-----------+ | slave-binlog.000001 | 154 | +---------------------+-----------+ 1 row in set (0.00 sec) (root@localhost:mysql.sock) [(none)]>reset slave; Query OK, 0 rows affected (0.00 sec) 5、开启主从复制 1)关闭master1 和master2的防火墙 2)开启主从复制 (root@localhost:mysql.sock) [(none)]> CHANGE MASTER TO MASTER_HOST = '10.89.3.225', MASTER_PORT = 3309, MASTER_USER = 'repl', MASTER_PASSWORD = '123456', MASTER_AUTO_POSITION = 1 FOR CHANNEL 'master2';

Query OK, 0 rows affected, 2 warnings (0.02 sec) (root@localhost:mysql.sock) [(none)]>start slave; 3)查看主从复制状态 (root@localhost:mysql.sock) [(none)]>show slave status for channel 'master1'G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 10.89.3.224 Master_User: repl Master_Port: 3309 Connect_Retry: 60 Master_Log_File: master01-binlog.000001 Read_Master_Log_Pos: 151 Relay_Log_File: mysql-relay-bin-master1.000002 Relay_Log_Pos: 376 Relay_Master_Log_File: master01-binlog.000001 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 151 Relay_Log_Space: 591 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 123 Master_UUID: 3809e1da-25c0-11e8-93b1-080027857522 Master_Info_File: mysql.slave_master_info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log;
