openssh离线升级9.0的步骤总结---（针对与centos7）

序言：

ssh服务版本低会出现漏洞，对于安全要求较高的公司来讲，服务器的ssh加固最有效的方式就是平滑升级到最新版本，所以今天需要来讲一下平滑升级到ssh9.0的方法和步骤。

1：所需包下载地址如下:

Zlib官网：http://www.zlib.net/OpenSSL官网：https://www.openssl.org/OpenSSH官网：https://www.openssh.com/

2:准备工作：

需要升级前先开启telnet服务，防止当我们的ssh升级失败的时候没有可以远程链接机器的服务。

开启telnet服务：

1：检查是否安装了telnet rpm -qa telnet

2：未安装telnet的情况下先到 http://rpmfind.net/下载telnet的对应版本的rpm包上传到服务器后进行安装安装命令 rpm -ivh telnet-server*.rpm

3: 开启telnet 命令如下

systemctl start  telnet.socket

3: 安装与最终查询

3.1 创建自定义目录

mkdir   ssh_up

3.2：将准备好的zlib ssl，ssh的最新的安装包放置到服务器的自定义目录下

3.3：检查安装依赖是否都存在，不存在利用yum进行安装，yum源里没有的情况下缺少的包可以去 http://rpmfind.net/进行对应包的搜索和下载

yum install gcc gcc-c++ glibc make autoconf openssl openssl-devel pcre-devel pam-devel zlib-devel tcp_wrappers-devel tcp_wrappers

　3.4: 开启脚本安装ssh升级服务，脚本如下：步骤一定和文档一样才能用这个脚本，否则请自行按照自己的实际情况修改脚本。

　 3.5: 检查是否升级成功，查看是否为最新版本的ssh

ssh -V

centos7升级python2.7 centos7升级openssh9.0_源码包

3.6：如果升级成功之后，需要检查是否可以使用sftp，如果不可以使用，请检查自己的sftp-server的服务包的位置，查找到之后把位置替换到ssh的配置文件中后，重启ssh 命令如下：

find / -name sftp-server

vi /etc/ssh/sshd_config
找到Subsystem sftp internal-sftp  
替换为 Subsystem sftp 刚刚查找到的位置
保存后重启ssh

service sshd restart

3.7：善后工作: 关闭telnet服务

systemctl stop telnet.socket
