How can I install curl 7 34 or later on Amazon linux old instance

Question

We are using a few older instances to run our server at work, and since they are already in sunset mode we dont really want to update the AMIs. However we now need curl that is able to use TLS 1.2 and that means 7.34 or later. yum lists 7.27 as the latest on our instance, coming from amzn-updates repo. What are our options to update curl on these machines? The openssl version on these machines does support TLS1.2, it is only curl that doesnt support it. Specifically we need git to support TLS1.2.

Answer 1

add a new text file called /etc/yum.repos.d/city-fan.repo containing

name=City Fan Repo

baseurl=city-fan/yum-repo/rhel$releasever/$basearch/

enabled=1

gpgcheck=0

Either way, you should then be good to go :

yum install libcurl should update cURL to a (very) recent openSSL-based version (7.46.0 at the time of writing), which will resolve the "unknown protocol" errors for TLSv1 etc.

You may want to then remove/rename the city-fan.repo file if you want to prevent yum later also updating other packages you may have installed with "non-official" later versions.
