请帮忙.

推荐答案

这是我要解决此类问题的清单

Here is my checklist to troubleshoot this type of issue

• 您的实例的安全组可以吗? ELB需要有权访问您的实例以进行运行状况检查

• Is the Security group of your instance OK ? ELB needs to have access to your instance for the health check

您的Web/App服务器是否在实例上正确运行?它接受连接请求吗?

Is your Web / App server correctly running on the instance ? Does it accept connection requests ?

您的健康检查URL 200的HTTP返回代码是吗?如果您的运行状况检查URL返回其他任何内容(例如30x重定向)，则ELB会认为您的实例无效.您可以在Linux实例上使用curl -I进行检查.

Is the HTTP return code of your health check URL 200 ? If your healthcheck URL returns anything else (a 30x redirect for example), ELB will consider your instance invalid. You can check this with curl -I on Linux instances.
