Curl does not support HTTPS (Protocol HTTPS not supported or disabled in Libcurl)

When curl is installed by default, only the HTTP protocol is supported and the HTTPS protocol is not supported.

You can first use curl-v to see which protocols are currently supported by Curl:

[Email protected]/]# curl-v

Curl 7.19.4 (X86_64-UNKNOWN-LINUX-GNU) libcurl/7.19.4 openssl/1.0.2k zlib/1.2.11

Protocols:tftp ftp telnet dict http file FTPs

You can see that the HTTPS protocol is not supported. If you use the Curl command to access HTTPS, you will get an error:

Protocol HTTPS not supported or disabled in Libcurl

If you need to have curl support for the HTTPS protocol, you need to install OpenSSL and make it effective in curl:

Download and install the OpenSSL package (you do not need to reinstall if it is installed):

wget https://www.openssl.org/source/openssl-1.0.2k.tar.gz

wget  https://www.openssl.org/source/openssl-fips-2.0.14.tar.gz

Install Openssl-fips:

Tar xvf openssl-fips-2.0.14.tar.gz

CD Openssl-fips-2.0.14&&./config&&make&&make Install

Installing OpenSSL:

Tar xvf openssl-1.0.2k.tar.gz

./config shared--prefix=/usr/local/ssl&& make && make install

# Update LD

echo "/usr/local/ssl/lib" >>/etc/ld.so.conf

Ldconfig-v

# Configure the OpenSSL library

Recompile Curl

./configure–with-ssl=/usr/local/ssl

Make

Make install

See if curl already supports the HTTPS protocol:

Curl-v

Curl 7.19.4 (X86_64-UNKNOWN-LINUX-GNU) libcurl/7.19.4 openssl/1.0.2k zlib/1.2.11

Protocols:tftp ftp telnet dict http file HTTPS FTPs

You can see that the HTTPS protocol is already supported.
