MYSQL MGＲ 单写

1.MYSQL配置文件

[root@win1 3306]# cat my.cnf 
[client]
default-character-set = uft8
port    = 3306
socket = /data/3306/tmp/mysql.sock

[mysql]
prompt="u@mysqldb R:m:s [d]> "

 2.第一台设定，标红的部分只在第一个节点执行

mysql> reset master;
Query OK, 0 rows affected (0.01 sec)

mysql> CHANGE MASTER TO MASTER_USER='repl', MASTER_PASSWORD='123456' FOR CHANNEL 'group_replication_recovery';
Query OK, 0 rows affected, 2 warnings (0.01 sec)

mysql> SET GLOBAL group_replication_bootstrap_group=ON; 
Query OK, 0 rows affected (0.00 sec)

mysql> START GROUP_REPLICATION;
Query OK, 0 rows affected (2.04 sec)

mysql> SET GLOBAL group_replication_bootstrap_group=OFF;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT * FROM performance_schema.replication_group_members;
