1. 处理源码
 
tar -zxf openssh-9.1p1.tar.gz 
 
cd openssh-9.1p1/contrib/redhat/
 
cp -p sshd.pam sshd.pam.old
 
cp -p sshd.init sshd.init.old
 
cd ../../
 
#重新打包源码
 
tar -czf openssh-9.1p1.tar.gz openssh-9.1p1
 
2. 处理openssh.spec
 
注释的地方如下：
 
 94 #PreReq: initscripts >= 5.00
 
103 #BuildRequires: openssl-devel < 1.1
 
3. 手动创建目录
 
mkdir -p /root/rpmbuild/{SPECS,SOURCES}
 
4. 拷贝源码到目录
 
cp openssh-9.1p1.tar.gz x11-ssh-askpass-1.2.4.1.tar.gz /root/rpmbuild/SOURCES/
 
5.切换目录进行rpm包制作
 
cd rpmbuild/SPECS/
 
rpmbuild -ba openssh.spec
 
6.查看构建的成果

7.安装测试
 
升级安装只需要三个包：
 
openssh-9.1p1-1.x86_64.rpm
openssh-clients-9.1p1-1.x86_64.rpm
openssh-server-9.1p1-1.x86_64.rpm
 
# 备份配置文件
cp -p /etc/ssh /etc/ssh-backup
cp -p /etc/pam.d/sshd /etc/pam.d/sshd-backup
 
# 升级安装
 
yum localinstall *.rpm
 
# 覆盖/etc/pam.d/sshd
cat /etc/pam.d/sshd
