Question

我在angular2 +中使用Observables，它会命中nodejs，后者是从mysql数据库中获取数据的服务器.observables用于获取实时数据，因此angular在上述时间间隔内会命中mysql数据库。

代码-

   // Observables

    Observable.interval(10000).subscribe(x => {

    this.viewEntireData();

      });

所以我将sql变量设置为-

  max_connections;
  interactive_timeout;
  wait_timeout;
  connect_timeout;


mysql> show variables like 'max_connections';
 +-----------------+--------+
 | Variable_name   | Value  |
  +-----------------+--------+
 | max_connections | 100000 |
 +-----------------+--------+



  mysql>show variables like 'wait_timeout';
   +---------------+-------+
   | Variable_name | Value |
   +---------------+-------+
   | wait_timeout  | 8800  |
   +---------------+-------+



  mysql> show variables like 'interactive_timeout';
  +---------------------+-------+
  | Variable_name       | Value |
  +---------------------+-------+
  | interactive_timeout | 8800  |
  +---------------------+-------+



    +-----------------+-------+
    | Variable_name   | Value |
    +-----------------+-------+
    | connect_timeout | 100   |
    +-----------------+-------+

有了这些变量值，我的服务器就关闭了。我收到错误消息-

  Error: Connection lost: The server closed the connection.

现在，我希望我的连接永远不会关闭或结束。可能吗。请帮忙。

我的变量是-

 mysql> SELECT @@log_warnings;
 +----------------+
 | @@log_warnings |
 +----------------+
 |              2 |
 +----------------+


 mysql> select @@version;
 +-------------------------+
 | @@version               |
 +-------------------------+
 | 5.7.22-0ubuntu0.16.04.1 |
 +-------------------------+


 mysql> select @@log_error_verbosity;
 +-----------------------+
 | @@log_error_verbosity |
 +-----------------------+
 |                     3 |
 +-----------------------+

但是我仍然遇到错误-

“错误：ER_CON_COUNT_ERROR：连接过多”

请帮助。根据您的帖子，一切都很好。还是错误。

mysql中的变量max_connections，interactive_timeout，connect_timeout等无法满足我在angular2 +和nodejs中的问题
