平台：java8（不是tomcat，因为我用的是spring-boot，所以我用的是嵌入式tomcat）
所以我通过以下命令压缩
zip -r app.zip app.jar .ebextensions
.ebextensions 包含 test.config 文件。
files:
"/etc/nginx/conf.d/test.conf":
mode: "000644"
owner: root
group: root
content: |
client_max_body_size 10M;
我检查每个 ec2 实例，但不创建 /etc/nginx/conf.d/test.conf
并检查 /var/log/eb-activity.log
