cd openssl-3.0.7
./Configure --prefix=/usr/local/openssl
make -j && make install 
rm -rf /usr/include/openssl  /usr/local/lib64/libssl.so
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
ln -s /usr/local/openssl/lib/libssl.so /usr/local/lib64/libssl.so
ln /usr/local/openssl/bin/openssl /usr/bin
echo "/usr/local/openssl/lib" >> /etc/ld.so.conf
#使修改后的/etc/ld.so.conf生效 
ldconfig -v
export LDFLAGS=" -L/usr/local/openssl/lib"
export CPPFLAGS=" -I/usr/local/openssl/include"
export PKG_CONFIG_PATH="/usr/local/openssl/lib/pkgconfig"
