openssh源码编译打包成rpm（openssh-8.6p1，aarch64，4.19内核） – lvbibir's blog

一、下载openssh源码

https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.2p1.tar.gz

二、RPM包编译环境

yum install openssl-devel krb5-devel pam-devel rpm-build -y

mkdir /root/rpmbuild/{RPMS,SOURCES,SPECS}

解压缩文件并且存放于具体路径

将 openssh-9.2p1 存放于/root/rpmbuild/SOURCES

将 openssh.spec存放于 /root/rpmbuild/SPECS

注意原始文件路径为: /openssh-9.2p1/contrib/redhat

与之前的文档一样, 需要修改: 注意需要修改openssh.spec

如下三个配置:

%global no_x11_askpass 1

%global no_gnome_askpass 1

三、生成与安装rpm

cd /root/rpmbuild/SPECS

rpmbuild -bb openssh.spec

cd /root/rpmbuild/RPMS/x86_64/

四、备份和升级

cp /etc/pam.d/sshd /etc/pam.d/sshd_bak
cp /etc/ssh/sshd_config /etc/ssh/sshd_config_bak
rpm -Uvh ./*.rpm
cp -r /etc/pam.d/sshd_bak /etc/pam.d/
cp /etc/ssh/sshd_config_bak /etc/ssh/sshd_config
rm -rf /etc/ssh/ssh*key

systemctl daemon-reload

systemctl restart sshd

版本验证

ssh -V

启动文件报错

systemctl restart sshd
Warning: The unit file, source configuration file or drop-ins of sshd.service changed on disk. Run
'systemctl daemon-reload' to reload units.

自定义一份启动文件

vi /usr/lib/systemd/system/sshd.service

systemctl daemon-reload
systemctl restart sshd
