使用docker-compose安装Nextcloud

Nextcloud是一个企业存储和相互协作网站网站。代码开源。
官网：https://nextcloud.com/
官方项目：https://github.com/nextcloud/docker

如果你对容器化不太熟，可以安装宝塔面板。然后通过宝塔面板安装LNMP环境来部署Nextcloud。但是这个方法部署出来的环境不太稳定，不能达到高可用HA。而且LNMP安装非常耗时间。
如果想用docker启动一个高可用的Nextcloud网站，则需要安装docker和docker-compose。

sudo apt-get update
sudo apt-get install ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

# 验证docker安装成功
sudo docker run hello-world

wget https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-linux-x86_64 -O /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

# 验证docker-compose命令
docker-compose -v

mkdir -p /www/nextcloud/nginx # 存放nginx配置
mkdir -p /www/nextcloud/db # 存放数据库文件
mkdir -p /www/nextcloud/app # 存放nextcloud程序包

这种方式比LNMP更不稳定，不靠谱。
vim /www/nextcloud/compose.yml ，并写入如下内容

version: '2'

#volumes:
  #nextcloud:
  #db:

services:
  db:
    image: mariadb:10.5
    restart: always
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    volumes:
      - /www/nextcloud/db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_PASSWORD=nextcloud
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  app:
    image: nextcloud
    restart: always
    ports:
      - 11000:80
    links:
      - db
    volumes:
      - /www/nextcloud/app:/var/www/html
    environment:
      - MYSQL_PASSWORD=nextcloud
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db

最后启动集群

docker-compose -f /www/nextcloud/compose.yml up -d

访问 http://ip:11000即可登录nextcloud（端口号可以修改的）

vim /www/nextcloud/compose.yml ，并写入如下内容

version: '2'

#volumes:
  #nextcloud: /www/nextcloud/app
  #database: /www/nextcloud/db
  #nginx-proxy: /www/nextcloud/nginx

services:
  db:
    image: mariadb:10.5
    restart: always
    command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW
    volumes:
      - /www/nextcloud/db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=123456
      - MYSQL_PASSWORD=nextcloud
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud

  app:
    image: nextcloud:fpm
    restart: always
    links:
      - db
    volumes:
      - /www/nextcloud/app:/var/www/html
    environment:
      - MYSQL_PASSWORD=nextcloud
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db

  web:
    image: nginx
    restart: always
    ports:
      - 11000:80
    links:
      - app
    volumes:
      - /www/nextcloud/nginx/:/etc/nginx/
    #volumes_from:
      #- nginx-proxy

最后启动集群

docker-compose -f /www/nextcloud/compose.yml up -d

访问 http://ip:8080即可登录nextcloud
