How to install Oracle Linux using public oracle repositories?

I've downloaded OL7.5 Boot ISO image and want to install the last version of Oracle Linux.

Which address could I use to do it?

Solution 1:

To install specific version (for x86_64 platform):

http://public-yum.oracle.com/repo/OracleLinux/OL7/5/base/x86_64/

Number 5 between OL7/ and /base could be replaced by any available update number.

Installation of the last update of OL7 (for x86_64 platform) will be:

http://public-yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/

After installation we have:

[root@localhost ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.7 (Maipo)

Solution 2:

As of today, this content has changed and the above is not correct. But using pointers from Gryu's answer above, I was able to find that the current URL for specifying at install time for base OS for current 8.3 is:

public-yum.oracle.com/repo/OracleLinux/OL8/3/baseos/base/x86_64/

Note the additional "baseos" inclusion. Also note that Oracle intentionally obfuscates these paths, as you cannot simply "navigate" to them via normal browser to confirm, so you need to poke around to find the appropriate path if it changes.
