mysql5.6主从复制

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。
