Rocky Linux 9.4基于官方源码制作openssh 9.8p1二进制rpm包 —— 筑梦之路

2024年7月1日，openssh 9.8版本发布，主要修复了CVE-2024-6387安全漏洞。

由于centos 7的生命周期在6月30日终止，因此需要逐步替换到Rocky Linux，后续会有更多分享关于Rocky Linux的文章。

2. 内核版本和CPU架构

uname -r
5.14.0-427.16.1.el9_4.x86_64arch
x86_64

3. openssl版本

openssl version
OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)

准备工作

 1. 安装编译工具和依赖包

dnf install rpm-build zlib-devel openssl-devel gcc perl-devel pam-devel  libXt-devel gtk2-devel make perl krb5-devel -y

2. 下载所需要的源码

# openssh源码包wget https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.8p1.tar.gz# imake rpm包wget http://rpmfind.net/linux/epel/9/Everything/x86_64/Packages/i/imake-1.0.8-6.el9.x86_64.rpm# x11源码包wget https://src.fedoraproject.org/repo/pkgs/openssh/x11-ssh-askpass-1.2.4.1.tar.gz/8f2e41f3f7eaa8543a2440454637f3c3/x11-ssh-askpass-1.2.4.1.tar.gz

3. 创建所需目录和安装imake包

# 创建制作rpm包的目录结构mkdir -p rpmbuild/{SPECS,SOURCES}# 安装imake rpm包rpm -ivh imake-1.0.8-6.el9.x86_64.rpm# 将源码拷贝到对应的目录cp openssh-9.8p1.tar.gz rpmbuild/SOURCES/cp x11-ssh-askpass-1.2.4.1.tar.gz rpmbuild/SOURCES/

4. 修改spec文件

tar -zxvf openssh-9.8p1.tar.gzcp openssh-9.8p1/contrib/redhat/openssh.spec rpmbuild/SPECS/cd rpmbuild/SPECS/修改openssh.spec文件，主要添加ssh-copy-id命令，启用openssl版本显示

检查验证

对rpm包在干净的环境上安装检查验证，主要验证用户权限、登陆测试等方面。

# 安装依赖包dnf install chkconfig  initscripts# 安装openssh 9.8p1版本yum localinstall openssh-*.rpm# 设置权限chmod 600 /etc/ssh/ssh_host*#授权mv /etc/ssh/sshd_config /etc/ssh/sshd_config_bakecho "PermitRootLogin yes" >> /etc/ssh/sshd_config  #允许root远程登录#配置认证
