二、检查docker状态

[root@master npm]# docker version
Client: Docker Engine - Community
 Version:           20.10.17
 API version:       1.41
 Go version:        go1.17.11

 docker-init:
  Version:          0.19.0
  GitCommit:        de40ad0

三、安装docker-compose

1.安装docker-compose

 curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

2.给docker-compose文件添加执行权限

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

3.查看docker-compose版本

[root@master npm]# docker-compose -version
docker-compose version 1.25.0, build 0a186604

四、编辑docker-compose.yaml文件

1.编辑yaml安装文件

[root@master npm]# cat docker-compose.yaml 
version: "3"
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: always
    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: "192.168.3.146"
      DB_MYSQL_PORT: 3671
      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: always
    environment:
      MYSQL_ROOT_PASSWORD: 'npm'
      MYSQL_DATABASE: 'npm'
      MYSQL_USER: 'npm'
      MYSQL_PASSWORD: 'npm'
    ports:
      - 3671:3306
    volumes:
      - ./data/mysql:/var/lib/mysql

2.创建挂载目录

[root@master npm]# mkdir -p ./data
[root@master npm]# mkdir -p ./letsencrypt
[root@master npm]# mkdir -p ./data/mysql

3.安装Nginx Proxy Manager

[root@master npm]# docker-compose up -d

4.检查安装后容器状态

[root@master npm]# docker ps |grep npm
