dracut-initqueue errors while using virt-install + kickstart file
by Germano Massullo 06 Mar '17

06 Mar '17

I am trying to install a CentOS qemu/kvm virtual machine using a virt-install script[1]. Since Anaconda text user interface does not permit to users to edit filesystem type and mount points[2], I decided to use a kickstart file to customize such settings. To create a kickstart file, I used a trick: I installed a CentOS machine using Anaconda graphical user interface, and I made all customizations I need, then when the installation has been completed, I got the kickstart file (generated by Anaconda) in /root. [3] Then I added --grow flags to enlarge "/" as much as possible. After that, I started the virt-install script passing as input an ISO and the kickstart file, but the installation failed with logs [4]. Where did I make mistakes? Thank you for your time [1]: https://paste.fedoraproject.org/paste/OrbunqjpK7pxGlkUJdnV015M1UNdIGYhyRLiv… [2]: https://bugzilla.redhat.com/show_bug.cgi?id=1426126 [3]: https://paste.fedoraproject.org/paste/4zKZ3RopjwX5OmpuVAhwG15M1UNdIGYhyRLiv… [4]: https://paste.fedoraproject.org/paste/QYijE3MFeyoGpGdgSHPp715M1UNdIGYhyRLiv…

How to automatically confirm importing repo key?
by Yuri Kanivetsky 05 Mar '17

05 Mar '17

Hi, I'm trying to set up provisioning LXC container running CentOS. And among other things, I need to install nginx + passenger from a non-official repo (the docs: https://www.phusionpassenger.com/library/install/nginx/install/oss/el7/) With this playbook: - hosts: all tasks: # https://docs.ansible.com/ansible/yum_repository_module.html - name: Add repository yum_repository: # from https://oss-binaries.phusionpassenger.com/yum/definitions/el-passenger.repo name: passenger description: Passenger repository baseurl: https://oss-binaries.phusionpassenger.com/yum/passenger/el/$releasever/$bas… repo_gpgcheck: 1 gpgcheck: 0 enabled: 1 gpgkey: https://packagecloud.io/gpg.key sslverify: 1 sslcacert: /etc/pki/tls/certs/ca-bundle.crt # http://docs.ansible.com/ansible/command_module.html - name: (1) Add repository key (shell command) command: rpm --import https://packagecloud.io/gpg.key # # http://docs.ansible.com/ansible/rpm_key_module.html # - name: (2) Add repository key (python code) # rpm_key: # key: https://packagecloud.io/gpg.key # http://docs.ansible.com/ansible/yum_module.html - name: Install nginx yum: name={{ item }} with_items: nginx ansible fails performing the last task with: Failure talking to yum: failure: repodata/repomd.xml from passenger: [Errno 256] No more mirrors to try. https://oss-binaries.phusionpassenger.com/yum/passenger/el/7/x86_64/repodat…: [Errno -1] repomd.xml signature could not be verified for passenger no matter which way of importing key I choose (1 or 2). If I then ssh to container and run `yum install nginx` manually, it says: Retrieving key from https://packagecloud.io/gpg.key Importing GPG key 0xD59097AB: Userid : "packagecloud ops (production key) <ops(a)packagecloud.io>" Fingerprint: 418a 7f2f b0e1 e6e7 eabf 6fe8 c2e7 3424 d590 97ab From : https://packagecloud.io/gpg.key Is this ok [y/N]: And I suppose this extra confirmation request is what makes ansible fail. Can it be confirmed automatically? I tried to make it clear for those who don't use ansible, but feel free to ask questions. Thanks in advance.

How to rebuilt the pxe initramfs
by Andreas Benzler 05 Mar '17

05 Mar '17

Hello Guys, i read the official red hat documentation of "How built pxe initramfs", but it does not work" the inluded version of initramfs is about 42MB, mine 13MB. This is again one of more failure of redhat documentation. That's why i ask here. In my despair tried a very hard version: dracut -v -f -m "nfs network base" --add-drivers "nfsv4 (find /lib/modules/3.10.0-514.el7.x86_64/kernel/drivers/net ) $(find /lib/modules/3.10.0-514.el7.x86_64/kernel/drivers/virtio/) "; chmod 644 /boot/initramfs-3.10.0-514.el7.x86_64.img In the past i did it on ubuntu and it works flawless - means in principal I know what I do. Thanks for help Sincerely Andy PS: given kernel & initramfs from iso boots..

Python search path
by Alice Wonder 05 Mar '17

05 Mar '17

Hello, Working on a project to create clean spec files for libbitcoin for CentOS 7 (and eventually I want them to work in Fedora 25+ too) These spec files must work with the user defines an alternate %{_prefix} before building them. This means that python components would be installed in /opt/libbitcoin (or whatever) instead of in /usr so %{python2_sitelib} and %{python2_sitearch} no longer would apply. sys.path.append looks like the way to tell python about a new path to look for stuff, but I'm guessing there are guidelines somewhere for how that is suppose to properly done from within spec files. Unfortunately I can't find them, and search engines are getting harder and harder to use to find technical related information, always changing my query and showing me completely unrelated results. Anyway I didn't see anything in the Fedora packaging guidelines for python, that seems to be targeting a prefix of /usr Thanks for any links or suggestions.

CentOS 7 iso file SHA-256 hashes
by Darr247 04 Mar '17

04 Mar '17

I downloaded CentOS-7-x86_64-Everything.iso (8,233,418,752 bytes) by clicking on the 'Everything' link in the 'Rolling' line on https://wiki.centos.org/Download (supposedly the 1611 build). But when I look in the sha256sum.txt file from https://buildlogs.centos.org/rolling/7/isos/x86_64/ (where Chrome says that iso came from), there is no SHA hash for a file of that name. The reason I wanted to check it is because it's a different size than another one I found on my hard drive while looking through the Downloads history in Chrome. The other file I found was CentOS-7-x86_64-Everything-1611.iso (8,280,604,672 bytes), which returns a hash of af4969ebbdc479d330de97c5bfbb37eedc64c369f009cb15a97f9553ba441c88 and that matches the value given in the sha256sum.txt file for the file of that name. So, my question is tri-fold. what's the SHA-256 hash supposed to be for the file given when clicking the 'Everything' link on centos.org. then, why is the 'official' download link sending a file that's not listed in the hash results. and finally, why is the file sent thusly, different from another 'everything' iso allegedly from the same build? Thanks.

New C7 kernel ABI and kmods
by Lamar Owen 04 Mar '17

04 Mar '17

All, This is just a heads-up that the new C7 update kernel breaks ABI compatibility, at least as far as using the ELrepo nVidia drivers is concerned. I have posted more details to the ELrepo list; but since many folks use the Elrepo kmods I thought a heads-up would be appropriate. If you use the ELrepo nvidia kmod you will either need to hold off on the kernel update or uninstall the nvidia kmod.

C 7.3 sshd will not reload
by me＠tdiehl.org 04 Mar '17

04 Mar '17

Hi, Since upgrading to 7.3 I am having a problem getting sshd to reload after configuration changes. When I issue the command "systemctl reload sshd.service" I get the following error: "Unit sshd.service cannot be reloaded because it is inactive." It is obviously still running because I am connected over ssh to the machine and netstat shows it is listening. (vnewman pts3) # netstat -tulpn | grep ssh tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 29249/sshd tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN 3012/sshd: root@pts (vnewman pts3) # If I reboot the machine, then everything is OK. Has anyone seen this behavior or more importantly know how to fix it? Regards, -- Tom me(a)tdiehl.org Spamtrap address me123(a)tdiehl.org

A firefox/CentOS 7 oddity
by m.roth＠5-cent.us 03 Mar '17

03 Mar '17

I just switched to a new workstation, running C 7, the other day. I was looking at a blog, and in the thread of cmts, I wanted to play this one youtube video. I listened, then closed the tab. The video that had been *above* it in the thread started playing, and hasn't stopped. Every other time until now that I've done this, closing the tab shuts down the video.... mark
