搭建主从复制

mysql 主从复制流程图

Server version: 10.0.24-MariaDB-7 Ubuntu 16.04

• Master 记录二进制文件
• 导出数据并记录二进制位置
• 导入数据，设置二进制位置，并开启同步

具体配置流程

1.打开Master二进制记录功能

[mysqld]
server_id           = 132
log_bin             = /var/log/mysql/mysql-bin.log

2.授权Slave 锁表 并记录二进制位置

grant replication slave on *.* to "rep128E"@"192.168.110.128" identified by "123456";

FLUSH TABLES WITH READ LOCK;

SHOW MASTER STATUS\G;

3.导出表并传递到Slave

mysql -u root -p < backup.sql;
scp backup.sql root@192.168.110.128:/var/tmp/backup.sql

4.解锁Master

unlock tables;

5.导入数据并设置二进制文件同步点

mysql -u root -p < backup.sql；

CHANGE MASTER TO MASTER_HOST=‘192.168.110.132‘, MASTER_USER=‘rep128‘, MASTER_PASSWORD=‘123456‘, MASTER_LOG_FILE=‘mysql-bin.000001‘, MASTER_LOG_POS=508;

6.开启同步并查看状态

start slave;
SHOW SLAVE STATUS\G;
