AWS EC2修改内存和硬盘容量

AWS: EC2 -> Instances

修改内存：

1. stop实例

   
   Stop Instance

2. 此时Change Instance Type功能就可以使用了，修改成自己需要的大小，然后start实例

   
   Change Instance Type

P.S. Instance Type: https://aws.amazon.com/cn/ec2/instance-types/

Instance Type

修改硬盘：

1. 在实例下方找到device，点击EBS ID进入实例对应的Volume中

   
   Device

2. 修改Volume大小保存即可

   
   Actions

Modify Volume

接下来的一步容易被忽略，其实此时还没有完全修改成功！

3. 进入服务，运行以下命令：

ubuntu@ip-172-31-16-253:~$ df -h

此时看到/dev/xvda1 7.7G 7.7G 0 100% /变成了/dev/xvda1 39G 1.5G 38G 4% /，就代表成功了！
