Linux Centos7 升级最新版OpenSSH-9.6p1 有脚本（支持离线）_openssh离线升级到9.6

参考出处

链接: https://blog.csdn.net/gsj4719896/article/details/135122636

服务器/opt目录，新增离线安装的rpm，在文章顶部资源中下载

将openssh-9.6p1.tar.gz、openssl-1.1.1q.tar.gz、zlib-1.3.tar.gz、sshupdate2.sh，上传至服务器/opt目录。然后执行脚本sshupdate2.sh，命令如下：sh sshupdate2.sh。等待执行结果即可。查看SSH版本命令：ssh -V

脚本如下，也可在资源中直接下载（centos直接可以用，不用转换）

#!/bin/bash

升级成功别急着退出连接，先检查下配置文件，不然华为云堡垒机可能会出现连接不上的问题！！！

我的服务器配置文件地址：/etc/ssh/sshd_config
需要保证该配置文件有如下内容：HostKeyAlgorithms ssh-rsa,ssh-dss。若没有的话，手动加上在末尾。
