MySQL5.6 GTID方式，配置主从

数据导出：
mysqldump -uroot -p111111 -h127.0.0.1 -P3306 -q --single-transaction -R -E --triggers --default-character-set=utf8 -B db3306 > db3306.sql       //单库备份
mysqldump -uroot -p111111 -h127.0.0.1 -P3306 -q --single-transaction -R -E --triggers --default-character-set=utf8 --all-databases> all.sql     //全库备份

mysql -e "show databases;" -uroot -p111111 | grep -Ev "Database|information_schema|performance_schema|mysql" | xargs mysqldump -uroot -p111111 --databases {} > mysql_dump.sql

数据导入：
[root@mysql-1 mysql]# mysql -uroot -p111111 -h127.0.0.1 -P3307 < db3306.sql

编辑/etc/my.cnf，同时在master和slave上，添加如下内容：
log-bin         =mysql-bin
binlog_format   =row
log_slave_updates
gtid-mode       =ON
enforce-gtid-consistency=ON

[mysql@mysql-1 ~]$ cat /etc/my.cnf

登录主库：
mysql -uroot -p111111 -h127.0.0.1 -P3306
建立一个复制用户：
mysql>grant replication slave, replication client on *.* to repl@'localhost' identified by 'repl';
mysql>flush privileges;

登录从库：
mysql -uroot -p111111 -h127.0.0.1 -P3307
> stop slave;
> change master to
master_host='localhost',
master_port=3306,
master_user='repl',
master_password='repl';
> start slave;
