mysql主库:192.168.1.35
mysql从库:192.168.0.59
mysql版本:5.6.29
1、修改主库my.cnf配置
my.cnf位于/etc/my.cnf或mysql安装路径下,如/usr/local/mysql/my.cnf。
注意要写到[mysqld]下面
server-id=1
log-bin=mysqlmaster-bin.log
sync_binlog=1
innodb_buffer_pool_size=512M
innodb_flush_log_at_trx_commit=1
binlog-do-db =wybb_group_lastest
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
lower_case_table_names=1
log_bin_trust_function_creators=1
重启主库mysql
service mysql restart
2、创建同步账号
grant replication slave on *.* to [email protected] identified by '123456'
3、查看主库状态,记录file、position
mysql> flush privileges;
mysql> show master status;
+------------------+----------+---------------------------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+---------------------------------+------------------+
| mysql-bin.000002 | 195 | wybb_group_lastest //同步数据库 | |
+------------------+----------+---------------------------------+------------------+
4、从库数据库配置
注意要写到[mysqld]下面
server-id=2
log-bin=mysqlslave-bin.log
sync_binlog=1
innodb_buffer_pool_size=512M
innodb_flush_log_at_trx_commit=1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
lower_case_table_names=1
log_bin_trust_function_creators=1
replicate-do-db=wybb_group_lastest
replicate-ignore-db=test,mysql
重启从库mysql
service mysql restart
5、配置连接主库
在从库mysql中执行
mysql> change master to master_host='192.168.1.35',master_user='slave',master_password='123456', master_log_file='mysql-bin. 000002',master_log_pos=195;
6、开始同步
在从库mysql中执行
mysql> start slave;
7、查看同步状态
登录从库mysql
mysql>showslave status \G

8、测试同步
修改主库中的数据,查询从库中是否修改。
