使用mysql shell创建集群的步骤，这里有sleep原因是太快执行会导致初始化元数据还没有加载导致异常报错

这里需要注意如果是低版本的话，configureReplicaSetInstance时候需要添加一个password参数，代表传入root密码，8.4.0版本不需要这个参数

cat replicaset_configure.js
dba.configureReplicaSetInstance('root@{{ mysql_cluster_servers_group[0] }}:3306', {clusterAdmin: "'repl'@'%'", clusterAdminPassword: 'Repl_xxxx'});

cat replicaset_sleep.sql
select sleep(10);

cat replicaset_create.js
rs = dba.createReplicaSet("replicaset");

cat replicaset_addinstance.js
var rs =dba.getReplicaSet();
rs.addInstance('{{ mysql_cluster_servers_group[1] }}:3306',{recoveryMethod: "clone"});

　　

使用mysql router命令添加集群脚本，因为查看到没有参数直接添加root密码，当前使用expect命令方式自动输入密码，防止交互式中断

cat auto_mysqlroute_pass.sh
#!/usr/bin/expect -f

set timeout 30
spawn  mysqlrouter --bootstrap root@{{ mysql_cluster_servers_group[0] }}:3306 --user=mysqlrouter
expect "Please enter MySQL password for root:"
send {{ mysql_pass }}\n
expect off
