基于mysql 5.7的GTID复制

1 主服务器上

vim  /etc/my.cnf
[mysqld]
server-id=17
log-bin
gtid_mode=ON
enforce_gtid_consistency


datadir=/data/mysql
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid

[client]
socket=/data/mysql/mysql.sock

service mysqld restart 

mysql> grant replication slave on *.* to repluser@'192.168.37.%' identified by 'centos';

2从服务器上

vim /etc/my.cnf
[mysqld]
server-id=27
gtid_mode=ON
enforce_gtid_consistency
                                                                                                                                                 
datadir=/data/mysql
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid

[client]
socket=/data/mysql/mysql.sock

service mysqld restart 

mysql>CHANGE MASTER TO MASTER_HOST='主服务器',
MASTER_USER='repluser',
MASTER_PASSWORD='centos',
MASTER_PORT=3306,
MASTER_AUTO_POSITION=1;

mysql>start slave;
