Spring Boot应用程序在弹性豆柄上启动失败
Spring Boot应用程序在弹性豆柄上启动失败
提问于 2019-08-11 16:27:20
我试图运行我的Spring + MySQL应用程序的弹性豆柄。不管我怎么尝试，我都会得到502 Bad Gateway。我尝试过将我的Spring端口更改为5000，但它似乎毫无帮助。
我已经尝试过在server.port=5000中添加application.properties。我也尝试过添加server.port=${PORT}。
每次我eb deploy日志显示如下：

这最终导致数据库连接失败。
如果您在日志中注意到，有以下一行：
03:10:13.291 [main] INFO o.h.h.i.QueryTranslatorFactoryInitiator - HHH000397: Using ASTQueryTranslatorFactory事实证明，在这一步之后，启动就失败了。不幸的是，没有一个很好的错误消息来描述什么是错误的，但是经过大量的测试后，我发现这是由于无法连接到数据库。
下面是我所采取的基本故障排除步骤。
- 在当地核实： 这应该是不言而喻的，但是关闭您的本地数据库并尝试启动您的应用程序。如果失败了，那么你就有了自己的问题，否则这不是你的根本原因。
- 验证所有拼写：
同样，这应该是不言而喻的，但是在解决了问题之后，检查一下您的拼写。例如，我在application.properties
jdbc:mysql://${MSYQL_HOST:test_host}:${MYSQL_PORT:3306}/${MYSQL_DB:test_db}中使用它作为数据源url。如果仔细观察，您会注意到我的MYSQL_HOST环境变量拼写错误。 - 和检查你的连接
在ssh‘into进入您的环境后尝试连接到您的数据库。执行
yum install MySQL之后，使用以下命令：MySQL -h 'rds-endpoint-url' -P 'rds-DB-port' -u 'db-username' -p。输入连接密码后，应输入MySQL提示符。如果没有，请检查RDS实例是否与ec2或elb实例位于同一个VPC中，并允许ec2或elb实例所具有的安全组。
说到底，这些一般性的步骤有望解决你的问题。
