前言： 根据 国家信息安全漏洞共享平台 漏洞统计报告，信息安全数据泄露，漏洞入侵时时刻刻都在发生着，我们必须实时监控漏洞发现与威胁感知，及时预警网络安全漏洞的存在，以便及时整改修复漏洞，避免产生更大的安全事故，确保业务和系统的网络安全、稳定，促进社会的和谐发展。

一、OpenSSH 介绍

OpenSSH 是 SSH （Secure SHell） 协议的免费开源实现。SSH协议族可以用来进行远程控制， 或在计算机之间传送文件。而实现此功能的传统方式，如telnet(终端仿真协议)、 rcp ftp、 rlogin、rsh都是极为不安全的，并且会使用明文传送密码。OpenSSH提供了服务端后台程序和客户端工具，用来加密远程控制和文件传输过程中的数据，并由此来代替原来的类似服务。

二、源码包官网

目前基于最新版本 OpenSSH-9.0p1、OpenSSL1.1.1q 更新 ，测试环境为Centos7.x以上，请结合个人情况参考更新，其他版本请自测！

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

注： 手动下载官方源码包时，可能会非常慢，可以去常用的镜像站点（比如 清华镜像站、阿里镜像站 等）去下载

三、OpenSSH 安装

1.开启 telnet 服务，临时关闭防火墙

由于一般登录方式为ssh，所以需要安装其他登录方式，比如Telnet服务，防止升级失败

#安装telnet
yum install xinetd telnet-server telnet -y

#备份文件securetty
mv /etc/securetty.bak
#配置telnet登录的终端类型,增加一些pts终端
pts=$'pts/0\npts/1\npts/2\npts/3' && echo "$pts" >> /etc/securetty

#开启服务
systemctl start telnet.socket
service xinetd start

#关闭防火墙（或者开启23端口）
systemctl stop firewalld.service 
systemctl disable firewalld.service

2.环境准备

#安装wget
yum install -y wget

#安装tar
yum install -y tar

#软件包准备
cd /opt   #解压目录
wget --no-check-certificate https://www.zlib.net/zlib-1.2.12.tar.gz
wget --no-check-certificate https://www.openssl.org/source/openssl-1.1.1q.tar.gz
wget --no-check-certificate https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-9.0p1.tar.gz

#解压软件包
tar -zxvf zlib-1.2.12.tar.gz
tar -zxvf openssl-1.1.1q.tar.gz
tar -zxvf openssh-9.0p1.tar.gz

#备份
mv /etc/ssh /etc/ssh.bak
cp /etc/pam.d/sshd.pam /etc/pam.d/sshd.pam.bak
cp /etc/init.d/sshd /etc/init.d/sshd.bak
cp /usr/bin/openssl /usr/bin/openssl.bak

##卸载原有的openssh
rpm -e --nodeps `rpm -qa | grep openssh`

###安装相关依赖包
yum install vim gcc gcc-c++ glibc make autoconf openssl openssl-devel pcre-devel pam-devel zlib-devel tcp_wrappers-devel tcp_wrappers;

3.SSH安装*

3.1 Zlib安装

#进入zlib解压目录
cd /opt/zlib-1.2.12

#编译安装
./configure --prefix=/usr/local/zlib

make && make test && make install

#
ll /usr/local/zlib
ldconfig -v
/sbin/ldconfig

3.2 OpenSSL安装

注： 1. SSL更新前如果编译目录下有原版本，需删除后编译，防止SSH编译失败！ 2.结尾处截图为初发文时间更新版本，和操作语句新版本不冲突

#进入openssl解压目录
cd /opt/openssl-1.1.1p

#编译安装
./config shared zlib --prefix=/usr/local/ssl

make clean && make -j 4 && make install 

#更新函数库
echo "/usr/lcoal/ssl/lib" >> /etc/ld.so.conf
ldconfig
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/ssl/lib/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/ssl/lib/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1

#检查是否升级成功
openssl version -a

3.3 OpenSSH安装

#进入openssh解压目录
cd /opt/openssh-9.0p1

#编译安装
./configure --prefix=/usr/local/ssh --sysconfdir=/etc/ssh --with-ssl-dir=/usr/local/ssl --with-zlib=/usr/local/zlib 

make -j 4 && make install 

#查看目录版本
/usr/local/ssh/bin/ssh -V

#复制新ssh文件
cp -rf /opt/openssh-9.0p1/contrib/redhat/sshd.init /etc/init.d/sshd
cp -rf /opt/openssh-9.0p1/contrib/redhat/sshd.pam /etc/pam.d/sshd.pam
cp -rf /opt/openssh-9.0p1/sshd_config /etc/ssh/sshd_config

cp -rf /usr/local/ssh/sbin/sshd /usr/sbin/sshd
cp -rf /usr/local/ssh/bin/ssh /usr/bin/ssh
cp -rf /usr/local/ssh/bin/ssh-keygen /usr/bin/ssh-keygen

#开启sshd
chmod u+x /etc/init.d/sshd;
chkconfig --add sshd      ##自启动
chkconfig --list |grep sshd
chkconfig sshd on

#允许root登录
echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config
echo 'Subsystem sftp /usr/local/ssh/libexec/sftp-server' >> /etc/ssh/sshd_config

#重启sshd服务
/etc/init.d/sshd restart
/etc/init.d/sshd status

#查看升级后ssh版本
ssh -V

4.关闭 telnet 服务

#关闭telnet服务
systemctl stop xinetd.service
systemctl stop telnet.socket

#卸载telnet服务
yum remove xinetd telnet-server telnet -y

#开启防火墙
systemctl start firewalld.service 
systemctl enable firewalld.service

5.SSH启动失败问题

5.1. Permissions 0737 for ‘/etc/ssh/ssh_host_rsa_key’ are too open”问题
解决方法：更改报错文件权限

chmod 600 /etc/ssh/ssh_host_rsa_key
chmod 600 /etc/ssh/ssh_host_dsa_key
chmod 600 /etc/ssh/ssh_host_ecdsa_key
chmod 600 /etc/ssh/ssh_host_ed25519_key

5.2. 升级完openssh后root账号无法登录的问题
解决方法：查下/etc/ssh/sshd_config的配置文件中。UsePAM 这个是否注释了，去掉注释并修改为UsePAM yes

四、OpenSSH-9.0p1 升级脚本*

注：考虑系统内容环境因素，脚本请根据个人情况，进行升级，固有些差异的地方需要根据实际情况修改！！
