搭建环境：

1.使用的vps： https://my.racknerd.com/clientarea.php
2.操作系统：Ubuntu 18.04 with Docker Preinstalled

1.安装 Docker 和 Docker-Compose

1.1安装docker：(因为我使用的系统已安装docker所以跳过这步)

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

1.2安装docker-compose

下载

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

赋予权限：

sudo chmod +x /usr/local/bin/docker-compose

查看版本：

docker-compose --version

2.安装lsof

apt-get install lsof

使用命令：lsof -i:<端口号> 查看80、81、443端口

3.正式安装 nginx-proxy-manager

创建存储位置(我是在这个位置创建的)：cd /root/data/docker_data/npm

cd /root/data/docker_data/npm

vi docker-compose.yml

version: "3"
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      # These ports are in format <host-port>:<container-port>
      - '80:80' # Public HTTP Port
      - '443:443' # Public HTTPS Port
      - '81:81' # Admin Web Port
      # Add any other Stream port you want to expose
      # - '21:21' # FTP
    environment:
      DB_MYSQL_HOST: "db"
      DB_MYSQL_PORT: 3306
      DB_MYSQL_USER: "npm"
      DB_MYSQL_PASSWORD: "npm"
      DB_MYSQL_NAME: "npm"
      # Uncomment this if IPv6 is not enabled on your host
      # DISABLE_IPV6: 'true'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
    depends_on:
      - db

  db:
    image: 'jc21/mariadb-aria:latest'
    restart: unless-stopped
    environment:
      MYSQL_ROOT_PASSWORD: 'npm'
      MYSQL_DATABASE: 'npm'
      MYSQL_USER: 'npm'
      MYSQL_PASSWORD: 'npm'
    volumes:
      - ./data/mysql:/var/lib/mysql

然后:wq保存退出

安装

docker-compose up -d

至此已经搭建完成，使用你的服务器ip:81访问

首次访问默认管理员用户，并且会要求你更改详细信息和密码
