Question

在我的EC2 Linux中，我想创建一个cron作业来自动备份AWS RDS中的MySql数据库。我试图运行

/usr/bin/mysqldump -u dbusername -p'dbpassword' dbname > /path/backup.sql

但我收到了错误

"Warning: Using a password on the command line interface can be insecure.
mysqldump: Got error: 1045: Access denied for user 'dbusername'@'localhost' (using password: YES) when trying to connect".

有什么问题，如何更改＆＃39; dbusername＆＃39; @＆＃39; localhost＆＃39;到＆＃39; dbusername＆＃39; @＆＃39; xxx.xxxxxxxx.xx-xxxxxx-x.rds.amazonaws.com＆＃39;？

我还试过写一个MySql脚本来下载backup.sh但是因为它不能超越

mysql -u 'dbusername' --password="dbpassword" -h 'xxx.xxxxxxxx.xx-xxxxxx-x.rds.amazonaws.com'

它能够登录，但它显示了MySQL提示

除此之外的任何事情。

> use db;

它会显示

Warning: Using a password on the command line interface can be insecure.

Answer 1

mysqldump -u dbusername -p'dbpassword' -h hostname.here.com dbname > /path/backup.sql

相同的-h适用于所有mysql *命令，例如如果你想连接到RDB：

mysqldump -u user -p'pass' -h db.us-east-1.rds.amazonaws.com dbname

AWS EC2 Crontab自动备份RDS MySQL数据库
