利用闲置vps搭建bitwarden私人密码管理

作者：mmmmmiku

~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。

yum -y install docker
systemctl enable docker
systemctl start docker
curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
mkdir /usr/local/bitwarden
vi /usr/local/bitwarden/config.env
vi /usr/local/bitwarden/docker-compose.yml
cd /usr/local/bitwarden
docker-compose up -d

config.env

SIGNUPS_ALLOWED=true
DOMAIN=https://xxx.com
DATABASE_URL=/data/bitwarden.db
ROCKET_WORKERS=10
WEB_VAULT_ENABLED=true
ADMIN_TOKEN=wwwwwwwwwwwwwwww
WEBSOCKET_ENABLED=true

docker-compose.yml

version: '3'

services:
  bitwarden:
    image: bitwardenrs/server:latest
    container_name: bitwarden
    restart: always
    volumes:
      - ./data:/data
    env_file:
      - config.env
    ports:
      - "9999:80"
      - "9998:3012"

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

server
    {         
         listen 80;
         server_name    pw.xx.com ;  
         return      301 https://$server_name$request_uri;
}

server
    {
        listen 443 ssl http2;
        #listen [::]:443 ssl http2;
        #listen [::]:80;
        server_name pw.xx.com ;
        ssl_certificate /xx.crt;
        ssl_certificate_key /xx.key;
                
            server_tokens        off;
            ssl_protocols              TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
            ssl_prefer_server_ciphers on;
            ssl_ciphers "EECDH+AES128:RSA+AES128:EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5";
            ssl_session_cache shared:SSL:10m;
            ssl_session_timeout        1d;
            ssl_stapling               on;
            ssl_stapling_verify        on;
            resolver 8.8.8.8 8.8.4.4;
            resolver_timeout           10s;
            add_header Strict-Transport-Security "max-age=63072000;includeSubdomains; preload";
            add_header X-Frame-Options DENY;
            add_header X-Content-Type-Options nosniff;
            add_header X-XSS-Protection "1; mode=block";
            client_max_body_size 128M;
                
            location / {
           proxy_pass http://localhost:9999;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
        }
                location /notifications/hub {
           proxy_pass http://localhost:9998;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
        }
                location /notifications/hub/negotiate {
           proxy_pass http://localhost:9999;
        }
                
                # Optionally add extra authentication besides the AUTH_TOKEN
        # If you don't want this, leave this part out
        location /admin {
        # See: https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
           proxy_pass http://localhost:9999;
        }

        access_log  /home/wwwlogs/pw.xx.com.log;
    }

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。

先来个骚操作，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。

#!/bin/bash

#Funciont: Backup website and mysql database
#Author: licess
#Website: https://lnmp.org

Bit_name="bitwarden"
dropboxshell_dir="/usr/local/backup/dropbox_uploader.sh"
drop_dir=/${Bit_name}/$(date +"%Y%m%d%H")
password="wwwwwwww"

#IMPORTANT!!!Please Setting the following Values!
Zip_Dir="/usr/local/bin/7za"
Backup_Home="/usr/local/backup/"
######~Set Directory you want to backup~######
Backup_Dir=("/usr/local/bitwarden")


#Values Setting END!

OldBackup=${Bit_name}$(date -d -7day +"%Y%m%d%H").7z
Old_DROPBOX_DIR=/${Bit_name}/$(date -d -30day +"%Y%m%d%H")

Backup_Dir()
{
    Backup_Path=$1
    Dir_Name=`echo ${Backup_Path##*/}`
    Pre_Dir=`echo ${Backup_Path}|sed 's/'${Dir_Name}'//g'`
    tar zcf ${Backup_Home}bit-${Dir_Name}-$(date +"%Y%m%d%H").tar.gz -C ${Pre_Dir} ${Dir_Name}
}

if [ ! -f ${MySQL_Dump} ]; then  
    echo "mysqldump command not found.please check your setting."
    exit 1
fi

if [ ! -d ${Backup_Home} ]; then  
    mkdir -p ${Backup_Home}
fi


echo "Backup bitwarden files..."
for dd in ${Backup_Dir[@]};do
    Backup_Dir ${dd}
done



echo "compass with 7z..."
${Zip_Dir} a -mhe -p${password} ${Backup_Home}${Bit_name}$(date +"%Y%m%d%H").7z ${Backup_Home}bit-${Dir_Name}-$(date +"%Y%m%d%H").tar.gz
rm -rf ${Backup_Home}bit-${Dir_Name}-$(date +"%Y%m%d%H").tar.gz

echo "upload to dropbox..."
${dropboxshell_dir} upload $Backup_Home/${Bit_name}$(date +"%Y%m%d%H").7z $drop_dir/${Bit_name}$(date +"%Y%m%d%H").7z
${dropboxshell_dir} delete $Old_DROPBOX_DIR

echo "Delete old backup files..."
rm -f ${Backup_Home}${OldBackup}

password这里填你想设置的压缩包密码。

需要注册dropbox（需要f~q）验证邮箱后，进入https://www.dropbox.com/developers/apps建立一个app并生成密钥

—

运行dropbox_uploader.sh后将密钥填进去
运行一次backup.sh是为了测试备份是否有效

最后crontab添加定时任务
0 13 * * * /usr/local/backup/backup.sh
0 22 * * * /usr/local/backup/backup.sh
在每天13点和22点备份到dropbox
