CentOS 5/6/7 基于开源项目制作openssh 9.6p1 rpm包—— 筑梦之路

阅读本书更多章节>>>>

背景介绍

开源项目地址：https://github.com/boypt/openssh-rpms.git

该项目主要支持了centos 5 、6、7版本，针对使用了比较老的操作系统进行openssh安全加固，还是不错的项目，使用简单、一件制作，欢迎大家去支持作者。这里我来使用试试，并将过程进行记录。

环境说明

操作系统：CentOS Linux release 7.3.1611 (Core)

CPU架构：x86

内核版本：3.10.0-514.26.2.el7.x86_64

准备工作

1. 准备源码

# 准备源码wget --no-check-certificate https://mirrors.aliyun.com/pub/OpenBSD/OpenSSH/portable/openssh-9.6p1.tar.gzwget --no-check-certificate https://www.openssl.org/source/openssl-1.1.1w.tar.gzgit clone https://github.com/boypt/openssh-rpms.git# 将源码下载放到downloads目录下

2. 准备编译打包环境

yum groupinstall -y "Development Tools"yum install -y imake rpm-build pam-devel krb5-devel zlib-devel libXt-devel libX11-devel gtk2-devel

3. 修改开源脚本

# 修改脚本pullsrc.sh# 第一处source version.env改为source ./version.env# 第二处wget OPENSSLSRCwget OPENSSHSRCwget ASKPASSSRC改为wget --no-check-certificate $OPENSSLMIR/$OPENSSLSRC wget --no-check-certificate $OPENSSHMIR/$OPENSSHSRCwget --no-check-certificate $ASKPASSMIR/$ASKPASSSRC修改脚本compile.shsource version.env改为source ./version.env

# 添加ssh-copy-id命令cd el7/SPECSvim  openssh.spec# 307 行后添加install -m755 contrib/ssh-copy-id $RPM_BUILD_ROOT/usr/bin/ssh-copy-id# 390行后添加%attr(0755,root,root) %{_bindir}/ssh-copy-id

# 修改版本openssl的版本 version.envOPENSSLSRC修改为openssl-1.1.1w.tar.gz

 编译打包

cd openssh-rpms && ./compile.sh el7

打包完成后二进制rpm包在目录openssh-rpms/el7/RPMS/x86_64下，源码包在openssh-rpms/el7/SRPMS/下，稍后我将放到我的资源中，若有需要的可自行下载。资源名称为：openssh9.6-centos7.3-x86-64.tgz，资源地址：https://download.csdn.net/download/qq_34777982/88668870

安装测试

# 安装更新yum localinstall openssh-*.rpm # 授权chmod 600 /etc/ssh/ssh_host_*# 重启服务systemctl  restart sshd && systemctl  enable sshd --now# 检查服务状态systemctl status sshd

FAQ

1. 修改yum源

为什么要修改yum源，系统默认是最新的yum源，在安装依赖包的时候会升级版本和内核，而由于centos 7.3比较老，会出现诸多兼容性问题，因此我们需要将yum改为7.3的。

以下文件作为参考：

2. 查看防火墙状态

在未关闭selinux、firewalld防火墙的情况下仍然可以正常连接。
