If it's a rhel7 installation ISO it might come up with a GRUB prompt if it's booting uEFI.

comment libc.so.6(GLIBC_2.14)(64bit)
Also, that's not really CentOS. It is part of the CentOS userland installed in an OpenVZ container. What you install will be severely limited, particularly if you want to load kernel modules.

comment how to untar file in linux red hat?
If its a modern GNU tar, just leave off the decompression algorithm, and just use tar xvf linux-2.6.32.65.tar.xz. Tar is smart enough to figure it out.

comment STDERR: yum-dump Repository Error: Cannot retrieve repository metadata (repomd.xml) for repository: epel. Please verify its path and try again
It looks like a connection timeout to all the EPEL mirrors simultaneously, which might be possible but more likely a local networking issue. Can you just run a curl -v 'https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64'?

comment setting up a relay port for postfix smtp on CentOS 7
I suggest reading Mutt's man page for more details. For example: "set smtp_url=smtp://myusername@myserver.domain.tld/"

Either run a mail client on the server (like mutt) or forward the port with ssh and use your Thunderbird client.

comment setting up a relay port for postfix smtp on CentOS 7
Are you able to authenticate and send mail through the submission (587) port from the mail host? I'm trying to determine if it's the firewall or the postfix setup.

comment setting up a relay port for postfix smtp on CentOS 7
Oh! I see. You want to set up an SMTP submission port (typically 587) on your mail server. You will need to open the 'submission' port on the firewall and add the SMTP submission service with SASL authentication.
