mysql state 2002_webman 无法连接mysql 提示SQLSTATE[HY000] [2002]

我的配置如下

'default' => 'mysql',

'connections' => [

'mysql' => [

'driver' => 'mysql',

'host' => env('DB_HOST', '192.168.1.15'),

'port' => env('DB_PORT', '3306'),

'database' => env('DB_DATABASE', 'tomdb'),

'username' => env('DB_USERNAME', 'root'),

'password' => env('DB_PASSWORD', '841222'),

'unix_socket' => env('DB_SOCKET', ''),

'charset' => 'utf8',

'collation' => 'utf8_unicode_ci',

'prefix' => '',

'strict' => true,

'engine' => null,

],

],

我直接使用mysql客户端在linux上是是可以正常连接的，

现在使用$name = Db::table('userInfo')->get();报错如下

webman数据库采用的是 illuminate/database。

composer require illuminate/database最新的代码，求W大佬指点问题在哪里，完全按手册操作的
