一、背景说明
openeuler 22.03 默认安装的openssh 版本为8.8p1，经绿盟扫描，存在高危漏洞，需要升级到最新。
官网只提供编译安装包，而openeuler 22.03 为rpm方式安装。
为了方便升级，先通过编译安装包，制作rpm包，并进行升级
如下为做好的rpm升级包，可直接下载使用：

1.1 系统版本查看 cat /etc/os-release
[root@localhost ~]# cat /etc/os-release
NAME="openEuler"
VERSION="22.03 LTS"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 LTS"
ANSI_COLOR="0;31"
[root@localhost ~]# 二、rpm包制作
2.1、安装制作的工具
配置yum源
[root@localhost ~]# cat /etc/yum.repos.d/iso.repo
[iso]
name=iso
baseurl=file:///iso
enabled=1
gpgcheck=0
[root@localhost ~]# 安装依赖包
yum install rpm-build zlib-devel openssl-devel gcc perl-devel pam-devel libXt-devel gtk2-devel make perl -y
下载并安装imake
下载imake包
wget https://mirror.nju.edu.cn/openeuler/openEuler-22.03-LTS/everything/x86_64/Packages/imake-1.0.7-17.oe2203.x86_64.rpm
[root@localhost iso]# ls
imake-1.0.7-17.oe2203.x86_64.rpm openEuler-22.03-LTS-SP1-x86_64-dvd.iso
[root@localhost iso]# yum localinstall -y imake-1.0.7-17.oe2203.x86_64.rpm

2.3 下载openssh9.3p1和x11-ssh-askpass-1.2.4.1.tar.gz
#将下载的文件放入SOURCES文件夹下
cd /root/rpmbuild/SOURCES/
#下载openssh9.3p1
wget https://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.3p1.tar.gz
#下载x11-ssh-askpass-1.2.4.1.tar.gz
wget https://src.fedoraproject.org/repo/pkgs/openssh/x11-ssh-askpass-1.2.4.1.tar.gz
重新制作openssh压缩包
因为下载的包缺一个sshd.pam.old，需要将现在系统的/etc/pam.d/sshd，拷到编译的目录中。如果没有改文件，后续编译会报错。
tar -xvzf openssh-9.3p1.tar.gz
cd /root/rpmbuild/SOURCES/openssh-9.3p1
cp /etc/pam.d/sshd /root/rpmbuild/SOURCES/openssh-9.3p1/contrib/redhat/sshd.pam.old
#回到SOURCE目录，重新tar包
cd ..
tar -zcpf openssh-9.3p1.tar.gz openssh-9.3p12.4 修改openssh.spec配置
#将openssh.spec配置文件拷贝到，编译目录下
cp /root/rpmbuild/SOURCES/openssh-9.3p1/contrib/redhat/openssh.spec /root/rpmbuild/SPECS/
cd /root/rpmbuild/SPECS
#修改openssh.spec配置
#1.不生成askpass包
cat /root/rpmbuild/SPECS/openssh.spec | grep no_gnome_askpass
cat /root/rpmbuild/SPECS/openssh.spec | grep no_x11_askpass
sed -i -e "s/%global no_gnome_askpass 0/%global no_gnome_askpass 1/g" openssh.spec
sed -i -e "s/%global no_x11_askpass 0/%global no_x11_askpass 1/g" openssh.spec
#2.解决openssl-devel < 1.1报错
cat /root/rpmbuild/SPECS/openssh.spec | grep openssl-devel
sed -i '/openssl-devel < 1.1/s/^/#/' openssh.spec
#3.解决PreReq报错
cat /root/rpmbuild/SPECS/openssh.spec | grep PreReq
sed -i '/PreReq/s/^/#/' openssh.spec
#4.解决Obsoletes报错
cat /root/rpmbuild/SPECS/openssh.spec | grep Obsoletes
sed -i '/Obsoletes:/s/^/#/' openssh.spec2.5 编译源码包，制作成rpm包
cd /root/rpmbuild/SPECS/
rpmbuild -ba openssh.spec

[root@localhost SPECS]# 三、升级openssh
下载制作好的rpm后，上传到其他主机升级openssh。
3.1 升级前检查
[root@localhost SPECS]# rpm -qa|grep openssh
openssh-clients-8.8p1-2.oe2203.x86_64
openssh-8.8p1-2.oe2203.x86_64
openssh-server-8.8p1-2.oe2203.x86_64
[root@localhost SPECS]#只用了3个rpm包
3.2 备份openssh配置文件
cp /etc/ssh/sshd_config /etc/ssh/sshd_config.202305093.3 升级openssh
yum localinstall -y openssh-clients-9.3p1-1.x86_64.rpm openssh-9.3p1-1.x86_64.rpm openssh-server-9.3p1-1.x86_64.rpm3.4 检查sshd的配置文件是否正常。
