(1)关闭88的数据库实例
(2)在89节点操作
查询组成员，发现88已不在组中
mysql> SELECT * FROM performance_schema.replication_group_members;
+---------------------------+--------------------------------------+-------------+-------------+--------------+
| CHANNEL_NAME | MEMBER_ID | MEMBER_HOST | MEMBER_PORT | MEMBER_STATE |
+---------------------------+--------------------------------------+-------------+-------------+--------------+
| group_replication_applier | f308d2d6-6c93-11e7-a5b1-000c2979c7bf | mgr90 | 3306 | ONLINE |
| group_replication_applier | f39c169e-6c93-11e7-a550-000c291d7bdb | mgr89 | 3306 | ONLINE |
+---------------------------+--------------------------------------+-------------+-------------+--------------+
2 rows in set (0.00 sec)
(3)写入数据
mysql> insert into t1 values(2,‘Mr.Li‘);
Query OK, 1 row affected (0.02 sec)
mysql> select * from t1;
+----+----------+
| c1 | c2 |
+----+----------+
| 1 | lalala |
| 2 | Mr.Li |
+----+----------+
5 rows in set (0.00 sec)
(4)启动88的数据库
修改配置文件，自动启动组复制
loose-group_replication_start_on_boot = on
group_replication_allow_local_disjoint_gtids_join = on
(5)再次查看组成员，发现88已重新加入组
mysql> SELECT * FROM performance_schema.replication_group_members;
+---------------------------+--------------------------------------+-------------+-------------+--------------+
| CHANNEL_NAME | MEMBER_ID | MEMBER_HOST | MEMBER_PORT | MEMBER_STATE |
+---------------------------+--------------------------------------+-------------+-------------+--------------+
| group_replication_applier | 715e9af4-6c93-11e7-aabf-000c291abb1f | mgr88 | 3306 | ONLINE |
| group_replication_applier | f308d2d6-6c93-11e7-a5b1-000c2979c7bf | mgr90 | 3306 | ONLINE |
| group_replication_applier | f39c169e-6c93-11e7-a550-000c291d7bdb | mgr89 | 3306 | ONLINE |
+---------------------------+--------------------------------------+-------------+-------------+--------------+
3 rows in set (0.00 sec)
(6)查看数据，发现数据已同步
mysql> use test1;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> select * from t1;
+----+----------+
| c1 | c2 |

| 2 | Mr.Li |
