Mariadb 无法通过MaxScale连接应用程序

我有3个节点Galera Cluseter和一个节点用于maxscale。问题是只有我在

maxscale.cnf

中定义的maxscale用户可以通过侦听器服务连接到集群。所有节点都在本地网络中，并且可以看到彼此

maxscale.cnf

[maxscale]
threads=1

[Galera-Monitor]
type=monitor
module=galeramon
servers=server1,server2,server3
user=maxscale
password=qwe123
monitor_interval=1000

[Read-Write-Service]
type=service
router=readwritesplit
servers=server1, server2, server3
user=maxscale
password=qwe123

[Read-Only-Service]
type=service
router=readconnroute
servers=server1, server2, server3
user=maxscale
password=qwe123
router_options=slave

[Read-Write-Listener]
type=listener
service=Read-Write-Service
protocol=MariaDBClient
port=4006

[Read-Only-Listener]
type=listener
service=Read-Only-Service
protocol=MariaDBClient
port=4008

[server1]
type=server
address=192.168.122.93
port=3306
protocol=MariaDBBackend

[server2]
type=server
address=192.168.122.17
port=3306
protocol=MariaDBBackend

[server3]
type=server
address=192.168.122.13
port=3306
protocol=MariaDBBackend

如您所见，

myuser

在通过maxscale节点连接时出现问题。我如何解决这个问题，并使任何应用程序都能用自己的用户连接到maxscale

编辑：

这是我的maxscale用户权限：

MariaDB [(none)]> show grants;
+--------------------------------------------------------------------------------------------------------------------------------+
| Grants for maxscale@192.168.122.222                                                                                            |

| GRANT SELECT ON `mysql`.`db` TO 'maxscale'@'192.168.122.222'                                                                   |
| GRANT SELECT ON `mysql`.`user` TO 'maxscale'@'192.168.122.222'                                                                 |
+--------------------------------------------------------------------------------------------------------------------------------+

基于此有用的链接：

检查节点配置的以下权限：

GRANT SELECT ON mysql.user TO 'maxscale'@'maxscalehost';
GRANT SELECT ON mysql.db TO 'maxscale'@'maxscalehost';
GRANT SELECT ON mysql.tables_priv TO 'maxscale'@'maxscalehost';
GRANT SELECT ON mysql.roles_mapping TO 'maxscale'@'maxscalehost';
GRANT SHOW DATABASES ON *.* TO 'maxscale'@'maxscalehost';

MaxScale日志是否包含任何其他错误？日志通常说明登录尝试失败的原因。另一项检查是确保您可以使用正确的凭据从客户端服务器（

@sky

）以及maxscale服务器（

@maxscale

）访问所有数据库。检查链接并添加maxscale的其余权限后，所有应用程序都可以通过maxscale连接到群集
