我正嘗試使用「felixge/node-mysql」包從Lambda中承載的nodejs代碼連接到我的Amazon RDS(MySQL)實例。我需要幫助來找出我做錯了什麼。我得到「連接ETIMEDOUT」錯誤。我的代碼在Lambda中託管,Lamda和RDS都是相同的帳戶和區域。我還將RDSFullAccess策略附加到IAM角色。 RDS實例也可以從所有IP訪問(無白名單/黑名單IP)。從node-mysql連接到Amazon RDS(MySQL)時出錯
與此同時,我能夠從我本地的MySQL Workbench以相同的憑據進行連接。
這裏是我的代碼:
var connection = mysql.createConnection({
host : 'xxxxxxxx.crhmtrscnbgt.us-east-1.rds.amazonaws.com',
user : 'my_user',
password : 'my_passowrd',
database : 'my_db',
port : '3306',
debug : true
});
connection.connect(function(err) {
if (err) {
console.error('error connecting: ' + err.stack);
return;
}
console.log('connected as id ' + connection.threadId);
});
var query = "SELECT * FROM users";
connection.query(query, function(err, rows) {
if (err) throw err;
console.log(rows);
});
輸出是:
