我正在使用node-mysql和大多数查询.在职的.一些查询不起作用. 我尝试了Node的每个版本(从0.5 ...直到(5.6.0)，也尝试了(4.0)和(4.1)，没有任何帮助.

我试图进行身体上的改变，但没有成功.我试图将sequence文件更改为:this._idleTimeout = -1;，但没有帮助.

I tried to change maually, and didn't work. I tried to change the sequence file to: this._idleTimeout = -1; and didn't help.

我阅读了这些问题和GitHub，但没有任何帮助.

I can try to fix it by myself, but I need more information. Where is the timeout, why? when? what is this type of message? Where is the timeout came from?

MYSQL_ERROR     { [Error: Handshake inactivity timeout]  
code: 'PROTOCOL_SEQUENCE_TIMEOUT',   fatal: true,   
timeout: 10000 }  

推荐答案

好的，超时来自Protocol.js文件行:162.如果您检出node-mysql，您将看到它是查询的变量超时".如果您将超时设置为远远高于默认值10000的值，则错误应消失.一个例子是

Ok, the timeout comes from the Protocol.js file line:162. If you checkout node-mysql you'll see that it is a variable "timeout" for queries. If you set the timeout to something a lot higher than 10000, the default, then the error should go away. An example is

pool = require('mysql').createPool({
    connectionLimit : 1000,
    connectTimeout  : 60 * 60 * 1000,
    acquireTimeout  : 60 * 60 * 1000,
    timeout         : 60 * 60 * 1000,
    host            : process.env.DB_HOST,
    user            : process.env.DB_USERNAME,
    password        : process.env.DB_PASSWORD,
    database        : process.env.DB_DATABASE
});

您还可以在Sequence.js文件(node_modules/mysql/lib/protocol/sequence/Sequence.js)中编辑超时

You can also edit the timeout in the Sequence.js file (node_modules/mysql/lib/protocol/sequence/Sequence.js)

this._timeout  = 100000;
