构建基于RHEL7(CentOS7)的OpenSSH9.5p1的RPM包和升级回退方案

发布时间:2024年01月12日

本文适用:RHEL7系列,或同类系统(CentOS7等)
文档形成时期:2023年
因软件世界之复杂和个人能力之限,难免疏漏和错误,欢迎指正。

环境准备

yum install rpmdevtools
#创建目录
rpmdev-setuptree
#或手动创建目录:

mkdir rpmbuild-openssh9.5p1; cd rpmbuild-openssh9.5p1
mkdir -p ./{BUILD,RPMS,SOURCES,SPECS,SRPMS}

安装依赖

yum install rpm-build gcc make wget openssl-devel krb5-devel pam-devel libX11-devel xmkmf libXt-devel

准备包
libressl-3.8.2.tar.gz openssh-9.5p1.tar.gz openssl-1.1.1w openssl-1.1.1w.tar.gz x11-ssh-askpass-1.2.4.1.tar.gz zlib-1.3.tar.gz
其中openssl-1.1.1w是同系统中编译好的,也就是说,先把openssl-1.1.1w编译安装,安装目标路径是/usr/local/openssl-1.1.1w,然后拷贝到SOURCES目录中,
所有包放SOURCES目录中,其中tar.gz包在spec中也可以指定地址下载,比如x11-ssh-askpass-1.2.4.1.tar.gz我就是下载的。
SOURCES/openssl-1.1.1w.tar.gz没用到,直接用编译好的。

准备spec文件
tar zxf openssh-9.5p1.tar.gz openssh-9.5p1/contrib/redhat/openssh.spec
放SPECS目录下
chown sshd:sshd SPECS/openssh.spec
修改openssh.spec之后如下:
no_gnome_askpass 0改为1
no_x11_askpass 0改为1
注释掉这一行:BuildRequires: openssl-devel < 1.1 大约在103或113行

%description
SSH (Secure SHell) is a program for logging into and executing
commands on a remote machine. SSH is intended to replace rlogin and
rsh, and to provide secure encrypted communications between two
untrusted hosts over an insecure network. X11 connections and
arbitrary TCP/IP ports can also be forwarded over the secure channel.

OpenSSH is OpenBSD's version of the last free version of SSH, bringing
it up to date in terms of security and features, as well as removing
all patented algorithms to separate libraries.

This package includes the core files necessary for both the OpenSSH
client and server. To make this package useful, you should also
install openssh-clients, openssh-server, or both.

%description clients
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package includes
the clients necessary to make encrypted connections to SSH servers.
You'll also need to install the openssh package on OpenSSH clients.

%description server
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
the secure shell daemon (sshd). The sshd daemon allows SSH clients to
securely connect to your SSH server. You also need to have the openssh
package installed.

%description askpass
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH.

%description askpass-gnome
OpenSSH is a free version of SSH (Secure SHell), a program for logging
into and executing commands on a remote machine. This package contains
an X11 passphrase dialog for OpenSSH and the GNOME GUI desktop
environment.

- Update to x11-askpass 1.1.1. (#21301)

构建

rpmbuild -ba SPECS/openssh.spec

重新构建前清理

rm -rf BUILD/openssh-9.5p1/ RPMS/x86_64/openssh-* SRPMS/openssh-9.5p1-1.el7.src.rpm 

RPM包下载

(资源如果不能打开是可能正在审核中,可过一会儿或次日访问)

安装前

注意事项

  • 升级安装后由于加密算法的区别,低版本的SSH工具可能无法连接,建议改用Xshell7或SecureCRT9.0以上版本;
  • 临时增加telnet终端,验证telnet登录是否正常,并连接多个ssh终端操作;
  • 升级前备份;
  • 先在测试环境或局部升级,逐步推进;

配置备份文件的时间缀
export datetime=$(date +%Y%m%d-%H%M)

开启telnet(可选)

升级过程中,sshd可能无法使用,因此需要安装telnet服务【telnet服务依赖于xinetd服务】
yum install xinetd telnet-server

Linux系统中默认不允许root账户telnet远程登录,解决方法有二:
方法一:移除配置文件,保证root账户能够远程登录
#mv /etc/securetty /etc/securetty.bak-${datetime}

方法二:配置允许root账户telnet远程登录
实践中采用方法二

cp /etc/pam.d/login /etc/pam.d/login.bak-${datetime}
sed -i "2s/^/#/g" /etc/pam.d/login


#并添加超级用户登陆设备至/etc/securetty文件
cp /etc/securetty /etc/securetty.bak-${datetime}
for i in `seq 0 10`; do echo "pts/$i" >> /etc/securetty; done

方法二结束

启用telnet和xinetd服务
systemctl enable telnet.socket
systemctl start telnet.socket
systemctl enable xinetd
systemctl start xinetd
systemctl status xinetd
systemctl status telnet.socket

如果开启了selinux需关闭
getenforce
setenforce 0
防火墙临时允许telnet

验证telnet登录是否正常
telnet ip

备份openssl和openssh(可选)

备份操作在本文档构建的RPM包安装时会自动完成,当然也可以手动操作一遍

mv /usr/bin/openssl /usr/bin/openssl.bak-${datetime}
mv /usr/include/openssl /usr/include/openssl.bak-${datetime}  #实际发现这个目录不存在
ls -l /usr/lib64/libssl.so #确认是否是软链接,和真实文件路径,以备还原,实际发现这个路径不存在
unlink /usr/lib64/libssl.so

mv /etc/ssh /etc/ssh.bak-${datetime}
mkdir /usr/bin/bak-${datetime}
ls -l /usr/bin/{scp,sftp,ssh,ssh-add,ssh-agent,ssh-keygen,ssh-keyscan} # 注:如果是软链接,没有备份必要,下列文件同理。发现实际上都不是软链接
cp -apf /usr/bin/{scp,sftp,ssh,ssh-add,ssh-agent,ssh-keygen,ssh-keyscan} /usr/bin/bak-${datetime}/
cp -apf /usr/sbin/sshd /usr/sbin/sshd.bak-${datetime}
cp -apf /etc/sysconfig/sshd /etc/sysconfig/sshd.bak-${datetime}
cp -apf /etc/pam.d/sshd /etc/pam.d/sshd.bak-${datetime}

安装

rpm -Uvh openssh-*.rpm --force --nodeps

遗留问题

在某些CentOS7上装好重启sshd时,会卡住,但不影响SSH连接,但有些系统正常,偿试过DNS、GSAPI无关,待深入排查,欢迎反馈和探讨。

验证升级结果

ssh -V

远程连接验证

回退

${datetime}为RPM包安装时为备份文件创建而生成的时间缀,假设为20240110-2000
执行:
datetime=20240110-2000

回滚openssl

/bin/cp -ap /usr/bin/openssl.bak-${datetime} /usr/bin/openssl
/bin/cp -ap /usr/include/openssl.bak-${datetime} /usr/include/openssl

验证结果:
openssl version
输出:
OpenSSL 1.0.2k-fips 26 Jan 2017

回滚openssh

rm -rf /etc/ssh 
datetime=备份时的时间缀
/bin/cp -ap /etc/ssh.bak-${datetime} /etc/ssh
/bin/cp -ap /usr/bin/bak-${datetime}/{scp,sftp,ssh,ssh-add,ssh-agent,ssh-keygen,ssh-keyscan} /usr/bin/
/bin/cp -ap /usr/sbin/sshd.bak-${datetime} /usr/sbin/sshd
/bin/cp -ap /etc/sysconfig/sshd.bak-${datetime} /etc/sysconfig/sshd
/bin/cp -ap /etc/pam.d/sshd.bak-${datetime} /etc/pam.d/sshd

mv /usr/lib/systemd/system/sshd.service.bak-${datetime} /usr/lib/systemd/system/sshd.service
systemctl daemon-reload
systemctl restart sshd

#回滚后验证结果
ssh -V
远程连接验证

现场整理或清理

关闭telnet和xinetd服务

systemctl disable telnet.socket
systemctl stop telnet.socket
systemctl disable xinetd
systemctl stop xinetd
systemctl status xinetd
systemctl status telnet.socket

cp -ap /etc/pam.d/login.bak-${datetime} /etc/pam.d/login
cp -ap /etc/securetty.bak-${datetime} /etc/securetty

防火墙策略还原

清理为telnet开启的白名单策略
