I have one task for today: to upload hyper-v vhdx image to azure and start vm. So let's try to realize this interesting thing.
Do the following steps:
(you can read detailed steps here)
Packer with Azure
Yes! It's works.
First of all you need to install packer. After that – Azure plugin for Packer (you could download executable package or compile proper package with GOlang placing it to directory with packer plugins).
In my case I used *.exe files, downloaded from Github release. Also you can find packer configuration for different OS here.
Lets analyze my configuration file and run packer to azure.
Powershell: Check variable for null
If your working a lot with parameters and inputs you need to check if variables have the right value and are not “null”.
You can check that (check if $variablename has $null as value):
Configuring Cisco on Mac Os through the console port
You'll need to get a usb-serial adapter and then connect with a console cable.
Connecting to the Console Port with Mac OS X. To connect a Mac OS X system USB port to the console using the built-in OS X Terminal utility, follow these steps:
Step 1. Use the Finder to go to Applications > Utilities > Terminal.
Step 2. Connect the OS X USB port to the router.
Step 3. Enter the following commands to find the OS X USB port number:
ERROR: The missing cookbook(s)
If you received error uploading cookbook to chef server:
knife cookbook upload rundeck
Uploading rundec
ERROR: Cookbook rundeck depends on cookbooks which are not currently
ERROR: being uploaded and cannot be found on the server.
ERROR: The missing cookbook(s) are: 'java' version '>= 0.0.0', 'yum' version '>= 0.0.0', 'apt' version '>= 0.0.0', 'supervisor' version '>= 0.0.0', 'database' version '>= 0.0.0', 'mysql2_chef_gem' version '~> 1.0.2', 'mysqld' version '~> 1.0.3'
Installing workstation for managing Chef server
A workstation is a computer that is configured to run knife, to synchronize with the chef-repo, and interact with a single Chef server. The workstation is the location from which most users will do most of their work.
We need ti install on our workstation:
- knife
- chef-sdk
- chef-repo
- ruby
Installing Chef on Centos 6
Today we will install chef server in our home lab based on proxmox 3.4.6. So we have installed server 2cpu, 2Gb memory, Centos 6.7
First of all I switched off selinux, and configured hostname of server in /etc/sysconfig/network and /etc/hosts
Let's go on:
#wget https://web-dl.packagecloud.io/chef/stable/packages/el/6/chef-server-core-12.1.2-1.el6.x86_64.rpm
# rpm -Uvh chef-server-core-12.1.2-1.el6.x86_64.rpm
# chef-server-ctl reconfigure
“Cannot run upgrade script on host” during upgrade from esxi 5.5 to 6.0
The host upgrade from ESXi 5.5 to ESXi 6.0 failed with the following error: „Cannot execute upgrade script on host“.
The data service timed out because a back-end task took more than 120
Today I received error on my vm summary page in Vsphere web client: The data service timed out because a back-end task took more than 120 seconds. See the vsphere-client-virgo.log for more details.
Just before that I removed a test vcenter server, which was connected to my PSC on production Vsphere instance.
You need to remove a stale vCenter Server from your SSO environment, use the cmsso-util. It may takes a long time but does the job.
Passwordless command line scripts with MySQL 5.6
I have several command line scripts to MySQL databases for zabbix statistic. These scripts set the password on the command line using the -p option.
With MySQL 5.6, a new warning is displayed every time my scripts run:
