我正在设置由三个实例组成的新MySQL InnoDB集群8.0.16：
我在mysql shell中运行JS脚本以构建集群：
mysqlsh --interactive --file=/tmp/MakeCluster.js
脚本：
var dbPass = "Somepassword"
var clusterName = "cluster"
try {
print('Setting up InnoDB cluster...\n');
shell.connect('admin@srv-mysql-01:3306', dbPass)
var cluster = dba.createCluster(clusterName);
print('Adding instances to the cluster.');
cluster.addInstance({user: "admin", host: "srv-mysql-02", password: dbPass})
print('.');
cluster.addInstance({user: "admin", host: "srv-mysql-03", password: dbPass})
print('.\nInstances successfully added to the cluster.');
print('\nInnoDB cluster deployed successfully.\n');
} catch(e) {
print('\nThe InnoDB cluster could not be created.\n\nError: ' + e.message + '\n');
}
集群已成功创建，但是在将第二个实例添加到集群时会出现以下错误：
A new InnoDB cluster will be created on instance 'admin@srv-mysql-01:3306'.
Validating instance at srv-mysql-01:3306...
This instance reports its own address as 192.168.100.201

Cluster successfully created. Use Cluster.addInstance() to add MySQL instances.
At least 3 instances are needed for the cluster to be able to withstand up to
one server failure.
Adding instances to the cluster.A new instance will be added to the InnoDB cluster. Depending on the amount of
data on the cluster this might take from a few seconds to several hours.

Please see more details on error log.. Query: START group_replication: MySQL Error (3092): ClassicSession.query: The server is not configured properly to be an active member of the group.

我想修复此错误。
我使用shell命令dba.checkInstanceConfiguration()检查了所有实例是否存在问题，并且没有出现错误。
但是在第2个实例的MySQL登录中有一些错误：
