项目场景：

微服务迁移至其它ECS服务器：

• 原ECS ip：110.xxx.xxx.xxx:11111

• 迁移至新ECS ip：220.xxx.xxx.xxx:22222

• nginx docker部署

实战

Step 1：原ECS ：修改nginx.conf

添加如下代码

	server {
		listen 11111;
	 
		location / {
			proxy_pass http://220.xxx.xxx.xxx:22222;
			proxy_set_header Host $host;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		}
	}

Step 2：原ECS ：修改 docker-compose.yaml

添加端口：11111:11111

version: '3.1'

services:
  nginx:
    restart: always
    container_name: nginx-java
    image: nginx:1.17.6
    ports:
      - 11111:11111
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
      - ./nginx-log:/var/log/nginx
      - ./html:/etc/nginx/html
      - ./cert:/etc/nginx/cert
    deploy:
      resources:
        limits:
          memory: 500M
        reservations:
          memory: 200M
          

Step 3：新ECS

确保服务正常http://220.xxx.xxx.xxx:22222

Step 4：原ECS ：重新构建nginx

docker-compose up -d --build
