yum install -y gcc openssl-devel pam-devel rpm-build 【下載相關依賴包】
wget http://10.10.8.8/openssl-1.0.2p.tar.gz 【下載ssl，可到相應資源網站去下載最新】
tar -zxvf openssl-1.0.2p.tar.gz && cd openssl-1.0.2p 【解壓】
./config --prefix=/usr/local/openssl --shared
make && make install 【編譯及安裝】
mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl /usr/include/openssl.bak
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl

./configure --prefix=/usr --sysconfdir=/etc/ssh --with-ssl-dir=/usr/local/openssl --with-zlib --with-md5-passwords --with-pam --with-tcp-wrappers 【可能會出現：configure: error: PAM headers not found 錯誤，需要安裝pam-devel的rpm包
make && make install
sed -i ‘s/#PermitRootLogin prohibit-password/PermitRootLogin\ yes/g‘ /etc/ssh/sshd_config 【允許root遠程登陸】
