其中 cache, config, media 这几个目录是需要被 copy 到新机器的，其中 media 我是通过 smb 挂载的，所以这里我就无需复制了。

2. 新机器挂载远程 media 目录

这里有一些 Linux SMB 的知识点，如依赖等，参考这里: #160

永久挂载，直接修改 /etc/fstab 文件:

sudo mkdir /mnt/media
sudo cat <<EOF >>/etc/fstab
//192.168.31.20/media /mnt/media cifs defaults,username=YOUR_SMB_USERNAME,password=YOUR_SMB_PASSWORD
EOF
sudo mount -a

如果你要的是临时挂载:

sudo mount -o username=YOUR_SMB_USERNAME,password=YOUR_SMB_PASSWORD //192.168.31.20/media /mnt/media

3. 新机器安装 docker Jellyfin

注意：这里已经安装了 docker, docker-compose

mkdir jellyfin && cd jellyfin
# 将最开始备份的 config, cache 复制到 jellyfin 目录，这里我用的是 rz 命令上传备份 zip 的
rz
unzip jellyfin.zip

此时目录应该有 config, cache 两个目录。然后继续上面的命令启动 docker：

touch docker-compose.yaml
cat <<EOF >docker-compose.yaml
version: '3'
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    user: 0:0
    restart: unless-stopped
    network_mode: host
    volumes:
      - ./config:/config
      - /mnt/media:/media
      - ./cache:/cache
    environment:
      - JELLYFIN_PublishedServerUrl=http://media.home.com
EOF

sudo docker-compose up -d

注意，这里有个问题，第一次启动时，旧用户密码未加载，需要重启一次 docker 才能正常登录旧用户，原因未知。

4. 新机器安装 Nginx 并配置

sudo apt install nginx
sudo touch /etc/nginx/sites-available/jellyfin
sudo cat <<EOF >/etc/nginx/sites-available/jellyfin
server {
    listen 80;
    server_name media.home.com;

    location / {
        proxy_pass http://127.0.0.1:8096;
    }
}
EOF
sudo ln -s /etc/nginx/sites-available/jellyfin /etc/nginx/sites-enabled/jellyfin
sudo nginx -s reload

5. 修改 dnsmasq，将域名映射到新机器

这里我的路由器是 Padavan，所以直接在路由器界面设置即可，以前的配置为：

address=/home.com/192.168.31.21

修改为：

address=/media.home.com/192.168.31.31
address=/home.com/192.168.31.21

6. 大功告成

[Bpazy]

cannot read: permission deined

威联通共享文件后，新创建了用户，并授予了 media 目录权限，但是其他机器通过该账户访问时，发现有部分文件无法查看。具体表现为，一个目录下有多个文件，但是其中有一个文件无法展示出来，即 ls -a 命令也无法展示。但是通过 cp 命令强制访问该文件，则提示权限不足。
原因暂时未知。

cp: cannot open '复仇者联盟.mp4' for reading: Permission denied

解决方案： 挂载的时候使用 admin 用户

sudo mount -o username=admin,password=YOUR_ADMIN_PASSWORD //192.168.31.20/media /mnt/media

关于 SMB 的详细知识，如命令安装、开机自动挂载等，参考这里: #160
