如何移除 openEuler 的 grub2 密码 1 问题现状在讨论问题之前，先假设这样的场景：某服务器管理员忘记了 root 用户的密码，不能登录服务器，此时需要进行怎样的操作来重置 root 用户的密码呢？一般的操作流程如下：重启服务器进入 grub2 界面（选择内核的界面）按 “e” 进入 grub2 配置界面，找到 linux 开头的行，将该行中的 ro 修改为 rw，并在该行的末尾加上 init=/bin/sh使用组合键 “ctrl+x” 进入单用户模式，获得 shell 操作界面，执行 passwd root 命令为 root 用户设置密码若 SELinux 为 Enforcing 状态，则还需要执行 touch /.autorelabel 命令以使系统重新打标签退出单用户，重启服务器，使用新的 root 用户密码登录系统从以上处理流程可以看到，即使在不知道服务器 root 用户密码的情况下，只要能接触到物理服务器，也能通过一系列操作进入系统。因此，出于安全考虑，对 grub2 加密是有必要的。以下内容摘自官方文档：GRUB (GRand UnifiedBootloader) 是操作系统启动管理器，用来引导不同系统（如Windows、Linux）。GRUB2 是 GRUB 的升级版。系统启动时，可以通过 GRUB2 界面修改启动参数。为了确保系统的启动参数不被任意修改，需要对 GRUB2 界面进行加密，仅在输入正确的 GRUB2 口令时才能修改openEuler 操作系统默认为 grub2 进行了加密并设置了密码，登录 grub2 的用户名为 root，登陆密码为 openEuler#12。官方文档也进行了说明，详见：帐号清单虽然对 grub2 设置密码比较安全，但是机房重地，并非人人都能接触到物理服务器。因此在某些场景下为 grub2 加密反而使操作变得繁琐，在实际生产中，也遇到很多想要取消 grub2 加密的需求，以下就该问题提出完整的解决方案2 如何取消 grub2 加密2.1 临时方案直接修改 /boot/efi/EFI/openEuler/grub.cfg 或 /boot/grub2/grub.cfg 文件，当然也可以修改 /etc/grub2-efi.cfg 文件（与前述文件是软链接关系），将如下代码删除：set superusers=root password_pbkdf2 root grub.pbkdf2.sha512.10000.5A45748D892672FDA02DD3B6F7AE390AC6E6D532A600D4AC477D25C7D087644697D8A0894DFED9D86DC2A27F4E01D925C46417A225FC099C12DBD3D7D49A7425.2BD2F5BF4907DCC389CC5D165DB85CC3E2C94C8F9A30B01DACAA9CD552B731BA1DD3B7CC2C765704D55B8CD962D2AEF19A753CBE9B8464E2B1EB39A3BB4EAB08删除上述代码后，再次重启系统进入 grub2 就不再需要输入密码。然而作为临时方案，这种操作是不能永久生效的当执行了 grub2-mkconfig -o /path/to/grub.cfg 命令或执行了能触发该命令的操作时，都会重新生成 grub.cfg 文件，使得被删除的代码又重新写入2.2 永久方案只要删除 /etc/grub.d/00_header 文件末尾 cat <<EOF ... EOF 部分的代码，即可实现永久取消 grub2 加密在临时方案中修改 grub.cfg 文件时，注意到删除的代码位于以下两行注释中：### BEGIN /etc/grub.d/00_header ### ...... set superusers=root password_pbkdf2 root grub.pbkdf2.sha512.10000.5A45748D892672FDA02DD3B6F7AE390AC6E6D532A600D4AC477D25C7D087644697D8A0894DFED9D86DC2A27F4E01D925C46417A225FC099C12DBD3D7D49A7425.2BD2F5BF4907DCC389CC5D165DB85CC3E2C94C8F9A30B01DACAA9CD552B731BA1DD3B7CC2C765704D55B8CD962D2AEF19A753CBE9B8464E2B1EB39A3BB4EAB08 ### END /etc/grub.d/00_header ###可见这两行用于加密的代码来自于 /etc/grub.d/00_header 文件，那么接下来修改这个文件。该文件末尾有以下代码，表示在生成 grub.cfg 文件时，通过 cat <<EOF ... EOF 命令将加密的代码写入 grub.cfg 文件：cat <<EOF set superusers=root password_pbkdf2 root grub.pbkdf2.sha512.10000.5A45748D892672FDA02DD3B6F7AE390AC6E6D532A600D4AC477D25C7D087644697D8A0894DFED9D86DC2A27F4E01D925C46417A225FC099C12DBD3D7D49A7425.2BD2F5BF4907DCC389CC5D165DB85CC3E2C94C8F9A30B01DACAA9CD552B731BA1DD3B7CC2C765704D55B8CD962D2AEF19A753CBE9B8464E2B1EB39A3BB4EAB08 EOF因此只要删除 /etc/grub.d/00_header 文件末尾 cat <<EOF ... EOF 部分的代码，即可实现永久取消 grub2 加密2.3 彻底解决方案删除 /usr/sbin/security-tool.sh 文件第 948 行的代码删除的代码内容如下：echo -e "cat <<EOF\nset superusers="root"\npassword_pbkdf2 root grub.pbkdf2.sha512.10000.5A45748D892672FDA02DD3B6F7AE390AC6E6D532A600D4AC477D25C7D087644697D8A0894DFED9D86DC2A27F4E01D925C46417A225FC099C12DBD3D7D49A7425.2BD2F5BF4907DCC389CC5D165DB85CC3E2C94C8F9A30B01DACAA9CD552B731BA1DD3B7CC2C765704D55B8CD962D2AEF19A753CBE9B8464E2B1EB39A3BB4EAB08\nEOF\n" >> /etc/grub.d/00_header在永久解决方案中，/etc/grub.d/00_header 文件末尾 cat <<EOF ... EOF 部分的代码也不是凭空产生的，而是由 /usr/sbin/security-tool.sh 这个文件的第 948 行代码写入的，因此只要将其删除，即可从源头上取消 grub2 加密3 总结grub2 加密的流程为：先通过 /usr/sbin/security-tool.sh 文件第 948 行的代码将加密指令写入 /etc/grub.d/00_header 文件末尾再通过/etc/grub.d/00_header 文件末尾的加密指令，将加密内容写入 grub.cfg 文件系统启动时读取 grub.cfg 文件的加密内容从而对 grub2 加密在了解 grub2 加密的流程后，就可以在每个阶段进行操作，从而达到彻底取消、永久取消、临时取消 grub2 加密的目的

基于 openEuler 22.03 LTS SP4 编译 docker 20.10.13 1 编译目标由于 openEuler 所有版本适配的 docker 版本为 18.09，版本比较低不能满足大部分使用场景。因此本文以基于openEuler 22.03 LTS SP4 操作系统编译 docker-ce-20.10.13 为例，演示在 openEuler 操作系统上编译高版本 docker 的操作流程2 环境准备2.1 网络环境由于编译 docker 所需的源代码资源都在外网，因此需要提前配置代理# 配置代理 PROXY_IP=192.168.230.1 PROXY_PORT=1080 export http_proxy=http://${PROXY_IP}:${PROXY_PORT} export https_proxy=http://${PROXY_IP}:${PROXY_PORT} export ALL_PROXY=http://${PROXY_IP}:${PROXY_PORT} export all_proxy=socks://${PROXY_IP}:${PROXY_PORT} # 测试代理 $ curl www.google.com2.2 编译工具安装必要的编译工具$ yum install -y rpm-build rpmdevtools gcc gcc-c++ make golang2.3 编译资源软件包名下载地址docker-ce-20.10.10-3.el8.src.rpmhttps://download.docker.com/linux/centos/8/source/stable/Packages/docker-ce-20.10.10-3.el8.src.rpmdocker-ce-cli-20.10.13-3.el8.src.rpmhttps://download.docker.com/linux/centos/8/source/stable/Packages/docker-ce-cli-20.10.13-3.el8.src.rpmdocker-ce-rootless-extras-20.10.13-3.el8.src.rpmhttps://download.docker.com/linux/centos/8/source/stable/Packages/docker-ce-rootless-extras-20.10.13-3.el8.src.rpmcontainerd.io-1.4.3-3.2.src.rpmhttps://repo.openeuler.openatom.cn/openEuler-preview/sw_arch/openEuler-22.03-LTS/sources/Packages/containerd.io-1.4.3-3.2.src.rpmdocker-scan-plugin-0.12.0-3.el8.src.rpmhttps://download.docker.com/linux/centos/8/source/stable/Packages/docker-scan-plugin-0.12.0-3.el8.src.rpm3 编译流程3.1 编译 docker-ce3.1.1 编译# 定义 GOPATH 路径 $ export GOPATH=/go # 设置不使用 Go Modules 功能 $ export GO111MODULE=off # 从 docker 官方仓库下载 docker-ce-20.10.10-3.el8.src.rpm 源码包 $ wget https://download.docker.com/linux/centos/8/source/stable/Packages/docker-ce-20.10.10-3.el8.src.rpm -P /root -2024-11-09 12:39:03-- https://download.docker.com/linux/centos/8/source/stable/Packages/docker-ce-20.10.10-3.el8.src.rpm Connecting to 192.168.230.1:1080... connected.

openEuler 搭建本地 repo 源 1 前言everything 镜像中包含了许多 rpm 包，可以提供基本的安装使用，然而还有一部分软件包需要连网到公网 repo 源中下载。但是在生产环境中，服务器大多数是不能连接公网的，因此需要搭建一个局域网 repo 源，即让一台能够连接公网的服务器从公网 repo 源中同步 rpm 包到本地，然后局域网的其他服务器再从这台能连接公网的服务器中下载 rpm 包2 所需的服务或命令2.1 Web 服务用于局域网中其他服务器访问，可以使用 httpd 服务或 nginx 服务2.2 dnf reposync 命令$ dnf reposync [OPTIONS] -c [CONFIG FILE] 指定配置文件运行（默认配置文件是 /etc/yum.conf） -q 安静操作 -v 显示详细信息 -b 尝试使用最佳的软件包版本 -C 完全从系统缓存运行，不更新缓存 -R [minutes] 最大命令等待时间 -y 所有问题自动回答 yes --assumeno 所有问题自动回答 no --enablerepo [repo] 启用其他存储库，可以指定多次 --disablerepo [repo] 禁用仓库，可以指定多次 --repo [repo], --repoid [repo] 仅使用指定的存储库 --exclude [package] 排除软件包 --forcearch ARCH 强制使用指定的架构 --arch [arch] 仅下载指定架构的软件包 --delete 删除存储库中不再存在的本地软件包 -n 仅下载最新的软件包 -p DOWNLOAD_PATH 指定软件包下载的位置 --norepopath 在下载目录中不重新生成以 `repo name` 命名的目录2.3 createrepo 命令$ createrepo [OPTION?] <directory_to_index> -q 以安静模式运行 -v 显示详细信息 -o 指定生成的元数据存放的位置 --excludes=PACKAGE_NAME_GLOB 指定生成元数据时排除的包 --update 在原有元数据上升级，只更新有变化的软件 --workers 读取 rpm 包的数量，默认为 53 同步官方源服务器名称用途操作系统版本IP 地址Server搭建局域网 repo 源openEuler 22.03 LTS SP1192.168.255.221Client模拟局域网内主机openEuler 22.03 LTS192.168.255.2203.1 Server 端配置3.1.1 系统基本设置# 关闭防火墙，并停止开机自启 $ systemctl stop firewalld $ systemctl disable firewalld #
