Use the screen command to restart the service in OpenStack In older versions of OpenStack, it is common to use./rejoin-stack.sh to restart all specified services, in the newest master branch, and no rejoin-stack.sh, then restart the service only first. Unstack.sh, and then./stack.sh. Of course not, this is a very waste of time. In fact, we can manage each of the OpenSt

Step 17: After receiving the request from Nova-compute, use resource tracker to declare the occupation of resources required for creating the Virtual Machine. Step 18: Call the neutron API to configure the network. The virtual machine is in the networking state.
It should be noted that although this step is to configure the network, it is mainly to prepare the data structure, and the real device is not created.
When creating a virtual machine, we specify the private network to w

OpenStack has become the first choice for many cloud computing vendors to build a private cloud. Many academic institutions also use OpenStack to build a small-scale test environment for students' experiments. Here we will share the process of using OpenStack Virtual Machine to build the Hadoop2.2.0 environment.
1. Prepare the VM Environment
I have recently read about Openstack and have been trying to install it. However, I have referenced a lot of information, which is not satisfactory. Since CentOS has been used for Linux, most Openstack installation is required on Ubuntu. I don't know why. I don't like Ubuntu. Maybe I think it's too fancy, and I always want to update something.

BKJIA exclusive Article] OpenStack is a set of platform software used to manage virtual machines. Instead of a single software, it integrates many components for collaboration. Simply put, for example, there are ten servers. In the case of VMware, we install esx or esxi on each server, and then install a vcenter, in the vcenter management interface, you can add the esx of ten servers to the vcenter by adding domain names or ip addresses. Similarly, Re

The resize (upgrade) function of openstack allows us to change the number of CPU cores, memory, and disk size of the Virtual Machine. Of course, the virtual machine can only be upgraded up and cannot be downgraded down. By analyzing the source code, we found that the resize process is actually a cold migration process, and the resize multi-transmits a flavor parameter. The following
