三台msyql服务器221,222,223，每台服务器开两个实例，3306作为主库，3307作为另外一台服务器的从库
参照：https://www.cnblogs.com/sky-cheng/p/10919447.html
进行双实例安装
三、每台服务器的3306实例创建一个复制账号
在172.28.5.221上
[root@push-5-221 ~]# mysql -uroot -p -S /var/lib/mysql/3306/mysql.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 16 Server version: 5.7.26 MySQL Community Server (GPL) Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. mysql> grant replication slave,replication client on *.* to ‘repl‘@‘%‘ identified by ‘XXXXXXX‘; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql>
在172.28.5.222上
[root@push-5-222 ~]# mysql -uroot -p -S /var/lib/mysql/3306/mysql.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 11 Server version: 5.7.26 MySQL Community Server (GPL) Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

三、打开每台服务器的3306配置文件，设置server_id,和log_bin日志参数
在172.28.5.221服务器的3306配置文件中打开日志文件设置
[root@push-5-221 ~]# vim /etc/mysql/my-3306.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [mysqld] # innodb_buffer_pool_size = 128M # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M user=mysql port=3306 datadir=/home/mysql-5.7.26/data/3306 socket=/var/lib/mysql/3306/mysql.sock server_id=2213306 log-bin=master-221 binlog_format=row #skip-grant-tables symbolic-links=0 pid-file=/var/run/mysqld/3306/mysqld.pid log-error=/home/mysql-5.7.26/log/3306/mysqld.log [mysqld_safe] log-error=/home/mysql-5.7.26/log/3306/mysqld.log
server_id=221 设置server_id
log-bin=master-221 设置log_bin日志文件名
binlog_format=row 指定日志格式为row
2、重启3306实例，使配置生效
[root@push-5-221 ~]# mysqladmin -uroot -p -S /var/lib/mysql/3306/mysql.sock shutdown [root@push-5-221 ~]# mysqld_safe --defaults-file=/etc/mysql/my-3306.cnf & [1] 3459 [root@push-5-221 ~]# 2019-05-27T02:55:18.758733Z mysqld_safe Logging to ‘/home/mysql-5.7.26/log/3306/mysqld.log‘. 2019-05-27T02:55:18.813602Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7.26/data/3306
3、客户端连接
^C [root@push-5-221 ~]# mysql -uroot -p -S /var/lib/mysql/3306/mysql.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.26-log MySQL Community Server (GPL) Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
4、显示server_id参数
mysql> show variables like ‘%server_id%‘; +----------------+---------+ | Variable_name | Value | +----------------+---------+ | server_id | 2213306 | | server_id_bits | 32 | +----------------+---------+ 2 rows in set (0.00 sec)
5、显示主库状态
mysql> show master status\G; *************************** 1. row *************************** File: master-221.000002 Position: 154 Binlog_Do_DB: Binlog_Ignore_DB: Executed_Gtid_Set: 1 row in set (0.00 sec) ERROR: No query specified
此时，需要记住上面的参数: File: master-221.000001 Position: 154 ，日志文件名和偏移量，需要在从库上做主从设置时要用到这两个参数
6、从库设置
在172.28.5.222服务器上的3307配置文件
[mysqld] # innodb_buffer_pool_size = 128M # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M user=mysql port=3307 datadir=/home/mysql-5.7.26/data/3307 socket=/var/lib/mysql/3307/mysql.sock server_id=2223307 symbolic-links=0 pid-file=/var/run/mysqld/3307/mysqld.pid log-error=/home/mysql-5.7.26/log/3307/mysqld.log [mysqld_safe] log-error=/home/mysql-5.7.26/log/3307/mysqld.log
7、重启3307实例，使配置生效
[root@push-5-222 ~]# mysqladmin -uroot -p -S /var/lib/mysql/3307/mysql.sock shutdown [root@push-5-222 ~]# mysqld_safe --defaults-file=/etc/mysql/my-3307.cnf & [1] 23445 [root@push-5-222 ~]# 2019-05-27T03:11:33.550199Z mysqld_safe Logging to ‘/home/mysql-5.7.26/log/3307/mysqld.log‘. 2019-05-27T03:11:33.610157Z mysqld_safe Starting mysqld daemon with databases from /home/mysql-5.7.26/data/3307
8、查看相应参数
[root@push-5-222 ~]# mysql -uroot -p -S /var/lib/mysql/3307/mysql.sock mysql> show variables like ‘%server_id%‘; +----------------+---------+ | Variable_name | Value | +----------------+---------+ | server_id | 2223307 | | server_id_bits | 32 | +----------------+---------+ 2 rows in set (0.00 sec)
9、执行从库命令
mysql> change master to -> master_host=‘172.28.5.221‘, -> master_port=3306, -> master_user=‘repl‘, -> master_password=‘Zaq1xsw@‘, -> master_log_file=‘master-221.000002‘, -> master_log_pos=154; Query OK, 0 rows affected, 2 warnings (0.31 sec)
10、启动从库
mysql> start slave; Query OK, 0 rows affected (0.05 sec)
11、显示从库状态
mysql> start slave; Query OK, 0 rows affected (0.05 sec) mysql> show slave status\G; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 172.28.5.221 Master_User: repl Master_Port: 3306 Connect_Retry: 60 Master_Log_File: master-221.000002 Read_Master_Log_Pos: 154 Relay_Log_File: push-5-222-relay-bin.000002 Relay_Log_Pos: 321 Relay_Master_Log_File: master-221.000002 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: 154 Relay_Log_Space: 533 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: 2213306 Master_UUID: 3e61e5be-7dff-11e9-8945-6c2b5992e632 Master_Info_File: /home/mysql-5.7.26/data/3307/master.info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log; waiting for more updates
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
同步线程都已经启动成功、
Exec_Master_Log_Pos: 154 同步主库日志文件偏移量跟主库的日志文件偏移量相同，说明已经完全同步
12、测试同步
在172.28.5.221上创建test库和test表，并插入一条记录
mysql> create database test; Query OK, 1 row affected (0.12 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | | test | +--------------------+ mysql> use test; Database changed mysql> create table test( uid int, name varchar(20)); Query OK, 0 rows affected (0.43 sec) mysql> insert into test(uid,name)values(1,‘aaaa‘); Query OK, 1 row affected (0.14 sec) mysql> select * from test; +------+------+ | uid | name | +------+------+ | 1 | aaaa | +------+------+ 1 row in set (0.00 sec)
此时，在172.28.5.222上连接从库3307
[root@push-5-222 ~]# mysql -uroot -p -S /var/lib/mysql/3307/mysql.sock Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 5 Server version: 5.7.26 MySQL Community Server (GPL) Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

Type ‘\c‘ to clear the current input statement. mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | | test | +--------------------+ 5 rows in set (0.00 sec) mysql> use test; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> show tables; +----------------+ | Tables_in_test | +----------------+ | test | +----------------+ 1 row in set (0.00 sec) mysql> select * from test; +------+------+ | uid | name | +------+------+ | 1 | aaaa | +------+------+ 1 row in set (0.00 sec)
已经跟主库数据同步成功了。
同样在172.28.5.222上将3306配置文件打开
[mysqld] #innodb_buffer_pool_size = 128M # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M user=mysql port=3306 datadir=/home/mysql-5.7.26/data/3306 socket=/var/lib/mysql/3306/mysql.sock server_id=2223306 log-bin=master-222 binlog_format=row #skip-grant-tables symbolic-links=0 pid-file=/var/run/mysqld/3306/mysqld.pid log-error=/home/mysql-5.7.26/log/3306/mysqld.log [mysqld_safe] log-error=/home/mysql-5.7.26/log/3306/mysqld.log
