Node.js 在没有任何操作的情况下被 mysql 自动崩溃 [英] Node.js crashing automatically by mysql without any operation in it

问题描述

我正在使用 node.js 并面临 node 崩溃的问题.错误信息如下所示.

I am working with node.js and facing a problem with crashing of node . Error message shown below.

Error: Connection lost: The server closed the connection.
   at Protocol.end (/var/www/versions/project/js/node_modules/mysql/lib/protocol/Protocol.js:78:13)
   at Socket.<anonymous> (/var/www/versions/project/js/node_modules/mysql/lib/Connection.js:81:28)
   at Socket.EventEmitter.emit (events.js:117:20)
   at _stream_readable.js:919:16
   at process._tickCallback (node.js:419:13)

我在节点服务器中使用 mysql 查询......但在崩溃时它没有对其进行任何操作......节点在不同的时间段内自动崩溃.

I'm using mysql queries in node server..but at crashing time it does not have any operation on it... node crashing automatically different period of time.

推荐答案

我发现使用连接池仅在需要时获取连接是最好的方法.

I have found that working with connection pools to grab a connection only when you need it is the best approach.

// do this once
var pool = mysql.createPool( opts );

// then, just before you need a connection do this
pool.getConnection(function(err, connection) {
    if (err) throw err;

    // use the connection

    // don't forget to release the connection when you are done...
    connection.release();
});
