Oracle Linux - Centos Replacement?

Hi,

We have used Centos for many years on our customer's servers and are now looking at a replacement.

Busy experimenting with Oracle Linux - has anyone any experience with it? 

It is supposedly a binary replacement for RHEL 8 and has 8.3, 8.4 & 8.5 iso's available.

I've loaded 8.5 but am getting the below error with D3_setup - not sure if 8.5 is too bleeding edge or Oracle Linux default repos are different to Centos/Redhat?

Any ideas welcomed! 

No repository match: *
d3depends for RHEL/ CentOS 8 - x86_64 [$YUM0] 0.0 B/s | 0 B 00:04
Errors during downloading metadata for repository 'd3depends':
- Curl error (9): Access denied to remote resource for ftp://d3mv-repo:d3getRep0@ftp.rocketsoftware.com/RedHatEnterpriseServer/8.5/x86_64/repodata/repomd.xml [Server denied you to change to the given directory]
Error: Failed to download metadata for repo 'd3depends': Cannot download repomd.xml: Cannot download repodata/repomd.xml

Thanks

I posted this close to midnight - was a bit weary! Shortly afterwards I did some digging in the setup scripts - fooled them to thinking it was Centos 8.3 and D3 loaded fine although I see some SELINUX issues which  I suspect made the loading quite slow - I'll fiddle with it later and advise.

Cheers
Tom

Hy it depends of wich version of d3 you are using

if is 10.2 you have to use version 7 ( all the releases)

if its 10.3 you have to use version  8 ( is suported only until version  8.4) and you are using 8.5

and rocket always sugest do disabe selinux

Rocket has certified D3 over Rocky Linux and Alma Linux. As you probably figured out already, the /etc/redhat-release string determines which repository to load, and there isn't one for Oracle Linux. You can load the dependencies by hand before running D3_setup, list is below.

As for selinux, unless you have some REALLY good reason to do otherwise, it's a good idea to change selinux to "disabled" from "enforcing" in the /etc/selinux/config file then reboot Linux.

Dependencies for 10.3:

yum install dialog
yum install gcc
yum install libcurl-devel
yum install libcurl.i686
yum install pam-devel
yum install pam-devel.i686
yum install xinetd
yum install net-tools
yum install psmisc
yum install glibc-devel
yum install glibc-devel.i686
yum install libgcc.i686
yum install ncurses-devel
yum install ncurses-devel.i686
yum install ncurses-libs.i686
yum install libidn
yum install libuuid
yum install openssl
yum install openssl-devel
yum install initscripts
yum install gcc-c++
yum install libstdc++
yum install libstdc++-devel
yum install mpfr-devel

Then make sure /usr/lib/pick exists and do this:

cat /dev/null > /usr/lib/pick/d3depends

I see Brian Says that Rocket is looking at other Linux flavours. While they are at it, why don't they look at Ubuntu as well, seeing that it is supposedly the most installed version of Linux. We have been using it for over 15 years and only use CentOS for our D3. A move to an Ubuntu version would be greatly appreciated.

@Brian Cram - thanks for your answer!

An update - I downloaded Oracle Linux 8.4, installed it, disabled SELINUX, loaded D3 10.3.3 and viola - all worked - didn't have to gyppo d3_setup_sub as the /etc/redhat-release shows "Red Hat Enterprise Linux release 8.4 (Ootpa)"

Seems like my initial use of 8.5 caused the issues (with a hint of SELINUX).

As per @Alex Polglaze, any chance of Ubuntu certification? It would also be my choice of distro.

Cheers

I would vote for D3 on Ubuntu, as well!!!

Hello one of the main reasons why it is not possible to certify ubuntu is because it is a debian based system. and d3 was developed for systems based on red hat, so in theory all linux distributions based on red hat (maybe work) such as centos, fedora, oracle among others, because they use .rpm packages and the base structure is practically the same. Ubuntu is based on debian which has a totally different architecture and uses .deb packages. it's all linux but they are very different architectures, that's why oracle 8.4 worked correctly, due to its base architecture being the same as centos 8.4 and redhat 8.4
