安装 openssl
备份原来的openssl
]# mv /usr/bin/openssl /usr/bin/openssl_bak
]# mv /usr/include/openssl /usr/include/openssl_bak
]# tar -xzf openssl-1.1.1h.tar.gz && cd openssl-1.1.1h && ./config --prefix=/usr/local/openssl --shared && make && make install

安装openssh
]# 安装openssh前 将openssl 安装到/usr/local/openssl
备份原来的 ssh配置
]# cd /etc/ssh && mkdir –p /root/sshbak && mv ./* /root/sshbak
]# cd /data/openssh-8.4p1
]# ./configure --prefix=/usr/local/openssh --sysconfdir=/etc/ssh --with-openssl-includes=/usr/local/openssl/include --with-ssl-dir=/usr/local/openssl --with-zlib --with-md5-passwords --with-pam
