SysCare: 系统热服务

介绍

​ SysCare是一个系统级热修复软件,为操作系统提供单机级与集群级安全补丁和系统错误热修复,主机无需重新启动即可修复该系统问题。 ​ 当前仅融合统一内核态/用户态热补丁技术,用户需聚焦在自己核心业务中,系统修复问题交予SysCare进行处理。后期计划根据修复组件的不同,提供系统热升级技术,进一步解放运维用户提升运维效率。

软件架构

​ 可以利用系统组件源代码与相应的patch问题,制作出相应组件补丁的RPM(包含补丁文件、依赖信息与配置信息等). 制作的补丁RPM,可以上传到相应的补丁仓库中,集群的系统demon定时去查询补丁仓库, 对系统中运行的CVE与软件错误进行热修复,保证系统安全、稳定、高效运行。

安装教程

DNF安装

  1. 正确配置dnf/yum仓库文件
  2. dnf update & dnf install syscare
  3. enjoy the tool

源码编译安装

  • 安装编译依赖

    $ kernel-version=$(uname -r)
    $ dnf install -y kernel-source-$kernel-version kernel-debuginfo-$kernel-version kernel-devel-$kernel-version
    $ dnf install -y elfutils-libelf-devel openssl-devel dwarves python3-devel rpm-build bison cmake make gcc g++
  • 编译并安装

    git clone https://gitee.com/openeuler/syscare.git
    cd syscare
    mkdir tmp
    cd tmp
    cmake -DCMAKE_INSTALL_PREFIX=/usr -DKERNEL_VERSION=$(uname -r) ..
    make
    make install
  • 离线编译 首先在网络的环境上执行cargo vendor下载所有依赖到./vendor目录下

    cd syscare
    cargo vendor

    源码目录创建.cargo/config.toml,并写入以下设置,下次编译就不需要联网了

    [source.crates-io]
    replace-with = "vendored-sources"
    
    [source.vendored-sources]
    directory = "vendor"

rpm安装

rpm -ivh syscare-*.rpm

使用说明

   --output ./output \
   --patch ./0001-Prevent-unauthenticated-client-from-easily-consuming.patch

内核模块热补丁制作

$ syscare build \
   --patch-name HP001 \
   --source ./kernel-5.10.0-60.91.0.115.src.rpm \
   --source ./testmod-1-1.src.rpm \
   --debuginfo ./kernel-debuginfo-5.10.0-60.91.0.115.aarch64.rpm \
   --output ./output \
   --verbose \
   --skip-cleanup \
   --patch ./0001-test.patch

  1. 确认补丁
$ sudo syscare accept redis-6.2.5-1/HP001
  1. 查询补丁状态
$ syscare status redis-6.2.5-1/HP001
  1. 查询补丁信息
$ syscare info redis-6.2.5-1/HP001
  1. 查询补丁目标软件信息
$ syscare target redis-6.2.5-1/HP001
  1. 查询所有补丁
$ syscare list

系统管理

  1. 快速重启系统
$ syscare reboot

命令行详细使用说明请见cli/README.md
