MySQL 8.0.18使用clone plugin重建MGR的实现

假设三节点mgr某个节点异常，需要重新把这个节点加入到mgr集群中，具体操作过程如下：

贡献者端执行（192.168.1.11）

drop user 'donor_clone_user'@'192.168.1.12';
create user 'donor_clone_user'@'192.168.1.12' identified by 'password';
grant backup_admin on *.* to 'donor_clone_user'@'192.168.1.12';
install plugin clone soname 'mysql_clone.so'; 

接收者端执行（192.168.1.12）

drop user 'recipient_clone_user'@'192.168.1.12';
create user 'recipient_clone_user'@'192.168.1.12' identified by 'password';
grant clone_admin on *.* to 'recipient_clone_user'@'192.168.1.12';
install plugin clone soname 'mysql_clone.so';
set global clone_valid_donor_list = '192.168.1.11:3311';
exit
mysql -urecipient_clone_user -ppassword -h 192.168.1.12 -p3311
clone instance from 'donor_clone_user'@'192.168.1.11':3311 identified by 'password';
exit
mysql -uroot -p
start group_replication;
select * from performance_schema.replication_group_members;
