MySQL ROUTER安装部署

在前一篇文章，测试安装了MySQL MGR集群，在磁盘文章中通过测试MySQL router实现VIP的功能和读写分离。

总体设计架构如下图
在这里插入图片描述

[root@mgrouter bin]# adduser mgrrouter
[root@mgrouter bin]# ./mysqlrouter --bootstrap root@192.168.56.104:3309 --directory /opt/mysql_router/mgrrouter/data  --name='gsprouter' --user=mgrrouter --force-password-validation
Please enter MySQL password for root: 
Error: Unable to connect to the metadata server: Error connecting to MySQL server at 192.168.56.104:3309: Access denied for user 'root'@'192.168.56.107' (using password: YES) (1045)
[root@mgrouter bin]# ./mysqlrouter --bootstrap mgrouter@192.168.56.104:3309 --directory /opt/mysql_router/mgrrouter/data  --name='gsprouter' --user=mgrrouter --force-password-validation
Please enter MySQL password for mgrouter: 
Error: Expected MySQL Server '192.168.56.104:3309' to contain the metadata of MySQL InnoDB Cluster, but the schema does not exist.
Checking version of the metadata schema failed with: Error executing MySQL query "SELECT * FROM mysql_innodb_cluster_metadata.schema_version": Unknown database 'mysql_innodb_cluster_metadata' (1049)See https://dev.mysql.com/doc/mysql-shell/en/deploying-production-innodb-cluster.html for instructions on setting up a MySQL Server to act as an InnoDB Cluster Metadata server[root@mgrouter bin]#
