MySQL 8.4 Release Notes
20.2.1.4 Launching 组复制
首先需要确保 Group Replication 插件已经安装在服务器 s1 上。如果您在选项文件中使用了plugin_load_add='group_replication.so'
,那么 Group Replication 插件已经安装,您可以继续下一步。否则,您必须手动安装插件;要做到这点,请使用mysql客户端,并执行以下 SQL 语句:
mysql> INSTALL PLUGIN group_replication SONAME 'group_replication.so';
要检查插件是否安装成功,请执行SHOW PLUGINS;
,并检查输出结果。它应该显示类似于以下内容:
mysql> SHOW PLUGINS;
