1、上傳openssl 1.1.1t源文件到 /usr/local/src/并解壓

2、編譯安裝

./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl --shared zlib
make
make install

3、相關配置

mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/lib64/openssl /usr/lib64/openssl.old
mv /usr/lib64/libssl.so /usr/lib64/libssl.so.old
ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/lib/libssl.so /usr/lib64/libssl.so

echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openssl/lib
ldconfig -v

4、檢查確認

openssl version
openssl version -a
