06 Jun '17

Hi, are there packages replacing the ancient perl version in Centos 7 with a more recent one, like 5.24? At least the state feature is required.

C7 ansible 2.3 become_method: su not working
by Mark Haney 05 Jun '17

05 Jun '17

I just don't know what else to try. I've beat my head on this for 3 days now and it's becoming obvious that either Ansible 2.3 is a complete disaster, or the CentOS 7 package is a complete cluster. Here's my problem. I am working on getting an ansible server to manage about 100 or so CentOS 6 servers. All have an unprivileged user account setup (up to 3 years before I got here in April) but that user account isn't setup with sudo access. The way to get to root is 'su'. I'm not a newbie with Ansible as I used it extensively in my previous position to manage ~70 or so Ubuntu servers. The Ansible is CentOS 7. I'm working on getting Ansible to play nice with privilege escalation using SU and NAFT has worked. Here's an example (very simple) playbook: Because I'm having to use 'su' I have to either add the user password to the inventory file or use the --ask-become-pass parameter to the command line. Every time I do, I get this: [root@ansible ~]# ansible-playbook playbooks/radtest.yml --ask-become-pass SUDO password: It bombs timing out on privilege escalation. Every single time. I'm absolutely frustrated and am almost ready to throw ansible to the curb for something that doesn't suck so bad. But before I do, I'm asking the list, anyone seen anything like this before? I could post to the ansible list, but it's a google group and God knows when I might get a reply. BTW, setting up root with key-only auth is an option, but would be a real PITA to configure 100+ external servers by hand with the keys and reconfig sshd for it.

CentOS 7 install: closest mirror not supported?
by Jos Vos 05 Jun '17

05 Jun '17

Hi, Do CentOS 7 installs not automatically use a closest mirror for installing like Fedora does, or is that due to the way I'm starting the install (virt-install)? Background: I'm trying to find the best way to do installs using basic local media (network install, but *without* the need to download the squashfs.img for every install) but without a full local mirror. On Fedora (25), it works fine using a local boot.iso (virt-install -l), but with CentOS 7 you then have to manually enter a repository URL. I also tried a local kernel/pxeboot tree with LiveOS/squashfs.img (the latter similar to Fedora's install.img?) with no result.

Dear Community I am trying to install MySQL 5.6 on a Raspberry PI 3B. Using my normal procedure by downloading the yum repo rpm and installing MySQL through that is not working. There is no rpm information for arm7. Can anyone please point me in a direction where I can find a procedure on how to install MySQL 5.6 on Centos 7 running on a PI3? Kind Regards, Leon

Upgrade 6 to 7
by Jerry Geis 03 Jun '17

03 Jun '17

I found this site https://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool Is this still the case - there is no upgrade path from 6 to 7 ? I have a few remote servers I'd like to upgrade (if possible). Thanks, Jerry

yum install <olderversion> does not downgrade
by Anand Buddhdev 03 Jun '17

03 Jun '17

We're using ansible to configure our CentOS 6 servers, and we have a task to install a specific version of a package: - name: install thrift2 yum: name=ripencc-thrift2-{{ version }} In this ansible task, the "version" variable is set by the operator. When we want to upgrade, it works. But today we had to downgrade, and noticed that ansible wasn't downgrading it. So we tried by hand (the installed version was 1.0.8): # yum install ripencc-thrift2-1.0.3 I don't have the output handy, because a colleague was working on it, but basically, yum said something like "package already installed" and refused to downgrade it, even though the package is in our repository. I have a strong sense that yum _used to_ downgrade packages if asked to install an older version, but perhaps I am misremembering. Nevertheless, I want to ask: is this a bug in yum? If asked to install a specific version, should it not upgrade OR downgrade as needed? Regards, Anand

CentOS 6.9, shredding a RAID
by m.roth＠5-cent.us 02 Jun '17

02 Jun '17

I've got an old RAID that I attached to a box. LSI card, and the RAID has 12 drives, for a total RAID size of 9.1TB, I think. I started shred /dev/sda the Friday before last... and it's still running. Is this reasonable for it to be taking this long...? mark

should NUMA be enabled?
by hw 02 Jun '17

02 Jun '17

Hi, should NUMA be enabled in the BIOS of a server that has two sockets but only a single CPU in one of the sockets? From what I´ve been reading, it is unclear to me if NUMA should be enabled only on systems with multiple CPUs in multiple sockets or if multiple cores of a single CPU in a single socket benefit from NUMA being enabled, and if memory access in general benefits from NUMA being enabled (in some other ways) even when there is only a single CPU in a single socket. It seems clear that NUMA should be enabled an can be taken advantage of when there are multiple CPUs in multiple sockets.
