WSGI mod, Python, Django, Celery and a nice fella virtualenv

  By , , , ,

Here I’ll show how to use Python (3.8.0 in the current example, but legit for latest 3.+ versions, not for os.name == ‘NT’) and virtualenv to setup WGSI enabled website on Django (or any) with implemented Celery + Flower + RabbitMQ. This example is my own path used for automated test framework: Octopus (not available now, but have dev branch opened: Lobster) Here only configurations and setup for Python 3.8.0, virtualenv, WSGI, Django, Celery (worker and beat services), Flower and that’s it. Later I’ll show Django + Celery configuration when they run together (sort of). You may want to install Python at first: Read When your modern and fancy python is installed, we’ll make a virtual environment for our website.Short Read more…

Oh my gosh BACULA config

  By , ,

Recently finished bacula config and run first one successfully! I’m really do not understand now, why does this tool have a complicated system with batch of daemons and modules. For my opinion, backup tool just should know from where to wherever make a backup and how often. But for further usage and remember this config, I’ll add it here.   Is is just a reminder, not a how-to, just want to not forget this. Job configs is not so complicate, intuitively understandable.

The conclusion after migration VMvsHyperV

  By , ,

So, what can I say before migration. First day looks good, nothing leaks, all services works as expected, have some additional configuration for MAC addresses etc. During migration I’ve accidentally lost one system disk for one of my VM and photos backup disk, but this is not an issue, because all important stuff have more then one backup. First expression about Hyper-V – it’s more thrifty to system resources, I’m still tuning it to make my vms run smoothly but this is the first thing I saw. Then, Hyper-V has a good mgmt console for all my needs, I have a small env. so I do not need an HUGE MGMT-VM to host vCenterServer because new VM ver. cannot beShort Read more…

Get Acess to VMFS from Windows (Vmplayer+Centos6)

  By , ,

Required: http://www.eastern.nl/2014/12/mounting-vmfs-centos-7/ http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/ Above May not work. So make a VMplayer VM with ESXi installation and mound physical disk where VMFS present. http://www.empirion.co.uk/vmware/vmware-vsphere-client-direct-download-links/ This is the biggest technical perversion I’ve ever did: There are: VmWare Vmplayer + ESXi mounted IDE disks with VMFS bridged network vSphereClient added datastores added NFS datastore to host where vmplayer runs (thought it were faster then just download) Windows Server 2012 NFS role and share enought space Bad method. Spent to much time. On the host where you installed Windows 2012 (for example) and where HDD with ESXI disks is mounted install one of this Hyper-V role vmware player Then create new virtual machine and install ESXi on it, just any trial ESXi you canShort Read more…

vmdk madness!

  By , , ,

When reading a lot of guides how better migrate from ESXi to Hyper-V I’ve saw some madness and then I become mad too. I decided to copy important VMs, which I don’t want to break, on my laptop. YEAH!   Guess what? I bet when I’ll migrate almost VMs to Hyper-V one last VM wouldn’t convert and I will run it under the VMbox with bridged NIC from Windows Server with Hyper-V. I feel it would be exactly like that! Read more…
