[系统运维]Centos7制作openssh8.9rpm包

1、yum安装编译依赖的组件

yum install -y rpm-build gcc gcc-c++ glibc glibc-devel openssl-devel openssl prce pcre-devel zlib zlib-devel make wget krb5-devel pam-devel libX11-devel xmkmf libXt-devel initscripts libXt-devel imake gtk2-devel lrzsz

虚拟机配置可参考本地yum源

2、建立编译目录

mkdir -pv /root/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}

3、源码包下载到/root/rpmbuild/SOURCES

wget http://mirror.aarnet.edu.au/pub/OpenBSD/OpenSSH/portable/openssh-8.9p1.tar.gz -O /root/rpmbuild/SOURCES/openssh-8.9p1.tar.gz

?4、解压spec编译文件

cd /root/rpmbuild/SOURCES/
tar -xf openssh-8.9p1.tar.gz  openssh-8.9p1/contrib/redhat/openssh.spec
mv openssh-8.9p1 /root/rpmbuild/SPECS

5、配置spec编译文件

a、不生成askpass包

b、解决openssl-devel < 1.1报错

cd /root/rpmbuild/SPECS/openssh-8.9p1/contrib/redhat/
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
sed -i '/openssl-devel < 1.1/s/^/#/' openssh.spec

6、编译openssh源码

rpmbuild -bb /root/rpmbuild/SPECS/openssh-8.9p1/contrib/redhat/openssh.spec

?编译最后无报错即编译成功

7、查看编译的RPM文件

在/root/rpmbuild/RPMS/x86_64/

?

附：openssh升级

1、先将本机telnet服务打开，避免升级后ssh服务挂掉

2、关闭selinux

3、安装/root/rpmbuild/RPMS/x86_64/下三个rpm包

?4、升级完后，更改ssh下面的key文件权限。不然重启ssh提示报错

chmod 600 /etc/ssh/ssh_host*key

?5、重启sshd，查看sshd状态，显示绿色running即可升级成功，关闭telnet服务。

?

ps：rpmbuild提示下面问题

1、install: cannot stat `contrib/redhat/sshd.pam.old': No such file or directory

解决：下载8.4的包，提取contrib/redhat sshd.pam.old sshd.init.old加到openssh 8.9p1
