Centos 6.7 add user to sudoers

You will only have to set up a local repository. Except if you installed a minimal iso image of CentOS 7 (in this case, you will need Internet access to get some additional packages from the CentOS repositories), you don’t need to register to anything. All the main packages are already inside the iso image.

What is the point of “2” in command “chmod 2770 /common”. Regarding the 6-th question. Let me know if I’m wrong. So I suppose that “chmod 770 /common” will be enough. There is no mentioning about executable date in the topic. It is a SGID, which relates only to executable files.

Options 02 and 03 work definitively but I suppose option 3 works too. In term of best way to mount a volume, I would say: option 02 (the best way because the most precise with the use of the UUID), option 03 (perfectly correct but slightly less precise) and option 01.

Now you can start grafana with systemctl start grafana-server, and configure it via the web interface. Don’t worry, we’re nearly there and there’s only a little left to do. Since we’re doing this all on the localhost, you’ll be able to cheat and use the data source settings in the screenshot. After you log in for the first time, you’ll be prompted to configure a few things including a data source, and a dashboard.

Log files btw) were always saying that credentials given were refused by rabbitmq, while tested manually). In Openstack Ocata, some things are mandatory, like the Placement API, but despite all the classes being applied, I had some issues to have it to run correctly when deploying an instance. But openstack nova services (all nova-*. Let me explain why. It’s true that I initially had a bug in my puppet code for the user/password to use to configure the rabbitmq settings, but it was solved and also applied correctly in /etc/nova/nova. Finally I found that some of the openstack puppet modules aren’t touching the whole config.

You will never need to use the chcon command in a RHCSA or RHCE exam, you can forget this command. No, you couldn’t use the chcon command because, when rebooting, an autorelabel might happen, removing the specified context. The semanage command is the only solution.

Once I’ve gotten through testing this board out, the plan is to build out a demo cluster to bring around to various conferences to showcase what we’re currently doing with the distribution, so you may hear a bit more from me on this in the future. This board is a bit of an improvement over previous Minnowboards, with an M. 2 slot, and dual ethernet, but lacks the onboard emmc available on previous versions. Since I had a few spare m2 ssds around, it’s not a huge deal for my purposes.

On CentOS, if adding the user to the group does not work immediately, you may
have to edit the /etc/sudoers file to uncomment the group name .

It’s no that I’m a fan of storing qcow2 images on top of NFS, but it seems it was my only option, and at least the most transparent/less intrusive path, would I need to migrate to something else later. So let’s test this before then using NFS through Infiniband (using IPoIB), and so at “good speed” (still have the infiniband hardware in place running for gluster, that will be replaced).

Let’s show how to do that, as in the above example, we configured the VM to run with 4Gb of ram, but only 3 are really seen inside (remember the 32bits mode and so the need for PAE on i386. At this stage, you can configure the node, etc. The only thing you have to remember is that of course kernel will be provided from outside the VM, so just extract it from an updated VM to boot on that kernel.

Reason is that when I need to test our packages, using my own Cubietruck or RaspberryPi3 is time consuming : removing the sdcard, reflashing with the correct CentOS 7 image and booting/testing the pkg/update/etc. Recently we got our hands on some aarch64 (aka ARMv8 / 64Bits) nodes running in a remote DC. On my (already too long) TODO/TOTEST list I had the idea of testing armhfp VM on top of aarch64.

    A fine idea unless the hardware lies. Since the drive lied, ZFS will incorrectly make stripes aligned to 512 bytes. This means stripes will almost always be non-aligned forcing the underlying device to use internal processing time which will slightly degrade write performance. ZFS will query the underlying device to understand how large the sectors are and use this information to determine the size of its dynamic width stripes. We say slightly because in practice a misaligned drive only writes less then 10% slower then a properly aligned drive. Today, drive hardware lies more often than not. Still, every byte per second counts right. Drives claim to have a logical sector size of 512 bytes (ashift=9 or 2^9=512) while the physical sectors are 4Kib (ashift=12 or 2^12=4096).
