roidba 人气:0这篇文章主要介绍了MySQL 8.0.18使用clone plugin重建MGR的实现,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧
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;
