OpenSSH9.8快速升级，CentOS7使用脚本一键快速升级至openssh9.8，连接无中断

本地测试环境CentOS7.4

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core)

确认当前openssh版本

[root@localhost ~]# ssh -V
OpenSSH_7.4p1, OpenSSL 1.0.2k-fips  26 Jan 2017

上传打包好的rpm包和执行脚本 http://121.37.180.195/p.php?8tp=s2.31475a8b9900.pg3

[root@localhost ~]# ls
openssh9.8rpm.tar.gz  openssh.sh

执行脚本

[root@localhost ~]# bash openssh.sh

执行结果

说明
rpm包是个人通过官网源码包编译的，在本地操作系统测试过，完全一键安装，比较适合伸手党，但是时间也是有成本的，大神和介意的请绕过。
打包教程网上都有，介意的可以自行学习。
