执行安装/升级

卸载当前版本的openssh

rpm -e `rpm -qa |grep openssh`
如果有依赖：
rpm -e `rpm -qa |grep openssh` --nodeps
1

rpm -e `rpm -qa |grep openssh`
如果有依赖：
rpm -e `rpm -qa |grep openssh` --nodeps

删除/etc/ssh/下所有文件(注意检查是否备份)

rm -rf /etc/ssh/*
1
       
rm -rf /etc/ssh/*

rpm安装openssh7.9p1

cd /root/rpmbuild/RPMS/x86_64/
rpm -iv --force --nodeps *.rpm

cd /root/rpmbuild/RPMS/x86_64/
rpm -iv --force --nodeps *.rpm

配置服务

设置开机启动：
chkconfig sshd on

编辑ssh配置文件：
vim /etc/ssh/sshd_config
配置：
UsePAM yes
如果要允许root用户ssh登录需要配置：PermitRootLogin yes

服务重启
service sshd restart

验证连接和版本
ssh -V

UsePAM yes
如果要允许root用户ssh登录需要配置：PermitRootLogin yes

服务重启
service sshd restart

验证连接和版本
ssh -V

由于升级后sshd会修改 /etc/pam.d/sshd 文件，用户将无法登录，报以下错误：

PAM unable to dlopen(/lib64/security/pam_stack.so): /lib64/security/pam_stack.so: cannot open shared object file: No such file or directory
PAM adding faulty module: /lib64/security/pam_stack.so

PAM adding faulty module: /lib64/security/pam_stack.so

解决办法是需要将之前备份的该文件还原回去。
安装包分发

rpm包编译生成好了之后可以分发到其他的服务器上，执行以下指令打包即可，此外也可以通过scp指令进行分发。

cd /root/rpmbuild/RPMS/x86_64/
zip openssh.zip *

cd /root/rpmbuild/RPMS/x86_64/
zip openssh.zip *
