利用virmach或者其他家的垃圾小鸡配上dropbox备份数据，好处在于成本极其低，一年甚至不到5刀！比没有80端口的NAS强多了

~使用bitwarden_rs搭建并每天备份两次到dropbox保证数据安全。

~理论上能跑docker就行，我搭建在virmach 1c384mb的小鸡上

~搭建环境为Centos7，只要能装docker就行。

~bitwarden的app和浏览器插件可以在对应的应用商店里找到，自动填充非常方便。安装后可以在设置里填自己的域名。

docker-compose.yml

DOMAIN填自己的域名，需要HTTPS。

ADMIN_TOKEN为管理面板密码，推荐使用“openssl rand -base64 48”生成。

SIGNUPS_ALLOWED=true，此项控制注册，只想自己用的话注册后可以改为false。

然后通过nginx反代开启SSL

由于vir的网络非常垃圾，建议去cf里生成orgin证书，套上cf食用。这样可以不用考虑源站证书续期

    }

然后vi /etc/rc.d/rc.local在最后加上/usr/local/bin/docker-compose -f /usr/local/bitwarden/docker-compose.yml up -d

这样开机就会自动启动bitwarden

访问https://你的域名/admin可以进去管理面板

到这里bitwarden就搭建完成可以使用了，不过个人还是建议配置数据备份。

先安装7Z，为的是把数据加密打包然后再传到dropbox

wget https://astuteinternet.dl.sourceforge.net/project/p7zip/p7zip/16.02/p7zip_16.02_src_all.tar.bz2
tar -jxvf p7zip_16.02_src_all.tar.bz2
cd p7zip_16.02
make && make install
mkdir /usr/local/backup
vi /usr/local/backup/backup.sh
wget https://raw.githubusercontent.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh
chmod +x backup.sh dropbox_uploader.sh
/usr/local/backup/dropbox_uploader.sh
/usr/local/backup/backup.sh
crotab -e

backup.sh，这个是用军哥lnmp的备份脚本改的。
