Nextcloud是私有云盘服务应用，由开源的Owncloud 项目fork而来，其中包含部分Owcloud原开发人员。其中服务器端Nextcloud和Owncloud基本上是一致的（owncloud9 和 nextcloud11），所以两者的安装过程大同小异。
P.S. 个人原本使用免费版的坚果云，因为1G流量实在不够使用，加上以前安装过owncloud，这次试着在服务器的docker上安装nextcloud
Host主机安装Nginx
Host主机配置SSL，安装证书
Docker安装NextCloud，开放8888端口
Host主机反向代理到Docker的NextCloud
测试
1、本机安装Nginx本内容参考：
Nginx安装
也可以使用apt-get install nginx 安装，但文件结构有不同

sudo apt-get update云主机是腾讯云，Docker我是使用阿里的Docker镜像安装的，所以这里两对头聚在一起了。。。
