apt install -y zlib

4、解压安装

tar zxf openssl-1.0.2j.tar.gz
cd openssl-1.0.2j
./config shared zlib
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
