ubuntu下使用7zip aes-256加密压缩zip文件

发布时间：February 20, 2020 // 分类： // No Comments

安装7zip：

apt install p7zip-full

加密压缩为7zip格式：

7z a -t7z -p123456 -mhe -spf file.7z file/
#-mhe加密文件名
#-spf被压缩目录包含完整的路径

加密压缩为zip格式：

 7z a -tzip -p123456 -mem=AES256 -spf file.zip file/
#-mem使用aes256加密

查看加密压缩文件信息：

7z l -slt file.zip 
7z l -slt file.7z

解压文件：

7z x -p123456 file.zip 
7z x -p123456 file.7z

解压到指定目录：

7z x prowinx64legacy.exe -owindows7-x64

ubuntu编译安装bitwarden_rs和web-vault

发布时间：February 17, 2020 // 分类： // 7 Comments

安装rust环境：

apt install git make gcc libssl-dev pkg-config curl
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

编译安装bitwarden_rs：

git clone https://github.com/dani-garcia/bitwarden_rs/
cd bitwarden_rs/
cargo build --features sqlite --release
mkdir /usr/local/bitwarden
cp target/release/bitwarden_rs /usr/local/bitwarden/

交叉编译arm64/aarch64版本bitwarden_rs：

#wget https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz
#tar -Jxvf gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz 
#export PATH=$PATH:`pwd`/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/
apt install gcc-aarch64-linux-gnu
git clone https://github.com/dani-garcia/bitwarden_rs/
cd bitwarden_rs/
mkdir .cargo
rustup target install aarch64-unknown-linux-gnu
echo '[target.aarch64-unknown-linux-gnu]' > .cargo/config
echo 'linker = "aarch64-linux-gnu-gcc"' >> .cargo/config
sed -i '/\[features\]/a\openssl-vendored = ["openssl/vendored"]' Cargo.toml 
cargo build --target="aarch64-unknown-linux-gnu" --release --features "sqlite" --features "openssl-vendored"

编译安装web-vault，内存需4G以上，不然可能会出错。已编译版本：https://github.com/dani-garcia/bw_web_builds/releases

curl -sL https://deb.nodesource.com/setup_10.x | bash -
apt install nodejs
git clone https://github.com/bitwarden/web.git web-vault
cd web-vault
git checkout v2.18.2
#2.18版本先执行再patch
npm run sub:init
wget https://raw.githubusercontent.com/dani-garcia/bw_web_builds/master/patches/v2.18.1.patch
git apply v2.18.1.patch
npm install
npm run dist
#新版本
npm run dist:oss:selfhost
cp -r build /usr/local/bitwarden/web-vault
export PATH=/usr/local/bitwarden/:$PATH

也可使用docker build：

apt install docker.io
git clone https://github.com/dani-garcia/bw_web_builds.git
cd bw_web_builds/
git checkout v2022.10.2
make docker-extract

如果遇到以下错误：
ERROR in node_modules/sweetalert/typings/sweetalert.d.ts(4,9): error TS2403: Subsequent variable declarations must have the same type. Variable 'swal' must be of type 'typeof import("/usr/local/src/web-vault/node_modules/sweetalert/typings/sweetalert")', but here has type 'SweetAlert'.
则：

sed -i 's/const swal/\/\/const swal/' node_modules/sweetalert/typings/sweetalert.d.ts

启动：

export WEB_VAULT_FOLDER=/usr/local/bitwarden/web-vault
export DATA_FOLDER=/usr/local/bitwarden/data
bitwarden_rs

ubuntu linux vps通过ipxe网络引导alpine dd备份/恢复vps系统

发布时间：February 8, 2020 // 分类： // No Comments

alpine从硬盘grub引导到内存中运行，重启后会破坏原硬盘分区，使用alpine官方推荐的使用ipxe netboot。
生成ipxe grub引导脚本，ssh_key为后续ssh登录目标系统操作的机器ssh public key，grub引导的ipxe lkrn可自行编译。

#!/bin/bash
#set -x
network=static
dns=8.8.8.8
ssh_key="ssh_key=https://www.haiyun.me/id_rsa.pub"
mirror="http://mirrors.aliyun.com/alpine/v3.11"
ipxe_file="https://www.haiyun.me/ipxe.lkrn"

valid_ip() {
  [[ $1 =~ ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]]
  state=$?
  return $state 
}
cidr2mask() {
    value=$(( 0xffffffff ^ ((1 << (32 - $1)) - 1) ))
    echo "$(( ($value >> 24) & 0xff )).$(( ($value >> 16) & 0xff )).$(( ($value >> 8) & 0xff )).$(( $value & 0xff ))"
}
which wget &> /dev/null && which ip &> /dev/null || {
  echo '请先安装wget和ip'
  exit
}
alpine_addr="ip=dhcp"
if [ "$network" == 'static' ]; then
  address=$(ip -o -f inet addr show | awk '/scope global/ {print $4}' | head -n 1)
  addr=$(echo $address | awk -F'/' '{print $1}')
  cidr=$(echo $address | awk -F'/' '{print $2}')
  gw=$(ip rou | awk '/default via/ {print $3}')
  mask=$(cidr2mask $cidr)
  alpine_addr="ip=${addr}::${gw}:${mask}::::${dns}:"
  echo 'ip：' $addr
  echo 'route：' $gw
  echo 'netmask：' $mask
  valid_ip "$addr" && valid_ip "$mask" && valid_ip "$gw" || {
    echo '获取网络信息失败'
    exit
  }
  read -r -p "以上IP信息是否正确? [Y/n] " input
  if [[ $input != "y" && $input != "Y" ]]; then
    echo "abort"
    exit
  fi
fi

if [ -f "/etc/redhat-release" ]; then
  grubfile=/boot/grub2/grub.cfg
  grubcmd=grub2-mkconfig
else
  grubfile=/boot/grub/grub.cfg
  grubcmd=grub-mkconfig
fi
#root=`grep "set root" $grubfile|sed -e 's/^[ \t]*//'|head -n 1`
root=$(grep 'set root' $grubfile | sed -e 's/^[ \t]*//' | sort | uniq -c | head -n 1 | awk '{print $2,$3}')
if mount | grep -q /boot; then
  dir=/
else
  dir=/boot/

sed -i 's/GRUB_DEFAULT=.*/GRUB_DEFAULT="netinstall"/' /etc/default/grub
$grubcmd -o $grubfile
cat /etc/grub.d/40_custom

ssh登录到alpine系统，dd备份的系统镜像保存到sshfs挂载远程服务器上，也可使用nfs。

apk add sshfs
modprobe fuse
sshfs -p 22 www.haiyun.me:/mnt/ /mnt/
dd if=/dev/vda | gzip > /mnt/pr.img
sync
umount /mnt/

恢复备份系统的grub引导：

mount -t ext4 /dev/vda1 /mnt/
chmod 644 /mnt/boot/grub/grub.cfg
sed -i 's/default="netinstall"/default="0"/' /mnt/boot/grub/grub.cfg
chmod 444 /mnt/boot/grub/grub.cfg
sed -i 's/GRUB_DEFAULT="netinstall"/GRUB_DEFAULT="0"/' /mnt/etc/default/grub
umount /mnt/

将要dd的目标系统通过以上方法引导至alpine系统并挂载sshfs，然后将之前备份的img dd到目标系统：

gzip -dc /mnt/pr.img |dd of=/dev/vda

如果要dd的目标系统硬盘比备份的系统硬盘大，要进行linux系统分区扩容，如果要扩容的分区下面有swap分区，记住swap的扇区大小和要扩容的分区起始位置，根据总扇区大小计算要扩充的分区扇区大小，将swap分区和扩充的分区删除再新建。

apk add util-linux e2fsprogs-extra
#修改分区扇区大小及位置，方法见上面链接
fdisk /dev/vda
partprobe 
e2fsck -yf /dev/vda1
resize2fs /dev/vda1
#如果有删除并新建swap分区，后面还要修改fstab swap uuid
mkswap /dev/vda2

挂载恢复后硬盘镜像，修改目标系统的IP地址和启动项：

mount -t ext4 /dev/vda1 /mnt/
#如果有更改swap分区，修改fstab uuid
blkid
vim /mnt/etc/fstab 
vim /mnt/etc/network/interfaces
chmod 644 /mnt/boot/grub/grub.cfg
sed -i 's/default="netinstall"/default="0"/' /mnt/boot/grub/grub.cfg
chmod 444 /mnt/boot/grub/grub.cfg
sed -i 's/GRUB_DEFAULT="netinstall"/GRUB_DEFAULT="0"/' /mnt/etc/default/grub
umount /mnt/
