协议数据包乱序

Question

我最近在A2 Hosting上上传了我的node.js应用，但出现此错误：

{ Error: Packets out of order. Got: 80 Expected: 0
    at Parser.write (/home/westudec/public_html/myapp/node_modules/mysql/lib/protocol/Parser.js:42:19)
    at Protocol.write (/home/westudec/public_html/myapp/node_modules/mysql/lib/protocol/Protocol.js:39:16)

    at Function.Module._load (module.js:438:3)
    at Module.runMain (module.js:604:10) code: 'PROTOCOL_PACKETS_OUT_OF_ORDER', fatal: true }

我从以下代码中得到该错误：

var connection = mysql.createConnection(connDB);
connection.connect();
connection.query(`SELECT * FROM action`, function(err, data){
    if(err) return console.error(err);
    else {
        console.log("data : ", data);
    }
})

在我的本地主机上，它工作正常，但是在服务器上，我收到了该错误。 关于此错误的文档非常差。 有人有主意吗？

谢谢

您需要通过以下方式在mysql配置文件（my.cnf）中增加mysql max_allowed_packet参数：

max_allowed_packet=500M
