解压源代码之后进行如下操作
./config
make
make install
mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl /usr/include/openssl.bak
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/ssl/include/openssl /usr/include/openssl
echo “/usr/local/ssl/lib” >> /etc/ld.so.conf
ldconfig -v
完成之后检验版本信息
openssl version -a
openssl 升级
