[schedule name] Game 1 of cloud computing competition - Private Cloud
An enterprise plans to use OpenStack to build an enterprise cloud platform to realize resource pooling elastic management, centralized enterprise application management, unified security authentication and authorization. The system architecture is shown in Figure 1, and the IP address planning is shown in Table 1.
[task 1] basic operation and maintenance task [5 points]
[Topic 1] basic environment configuration [1.5 points]
Use the user name and password provided, log in to the OpenStack private cloud platform provided, create two virtual machines using the CentOS7.5 image, and use 4V for the control node flavor_ 12G_ In 100g configuration, the computing node flavor uses 4v_8G_100G_50G configuration. The first network card uses the network provided, and the second network card uses the network created by itself (the network segment is 10.10.X.0/24, and X is the station number). After creating the virtual machine, ensure that the network communicates normally, and then configure the server according to the following requirements:
(1) Set the host name of the control node to controller and the host name of the calculation node to compute;
(2) Modify the hosts file to map the IP address to the host name; After completion, submit the user name, password and IP address of the control node to the answer box.
[root@localhost ~]# hostnamectl set-hostname controller [root@localhost ~]# hostnamectl set-hostname compute [root@localhost ~]# logout [root@controller ~]# vi /etc/hosts 192.168.100.10 controller 192.168.100.20 compute [root@controller ~]# scp /etc/hosts compute:/etc/hosts #The question doesn't ask to close the firewall. We closed it first when we practiced
[Title 2] Yum source configuration [1 point]
Use the provided HTTP service address. Under the HTTP service, there are network Yum sources for CentOS 7.5 and iaas. Use the HTTP source as the network source for installing the iaas platform. Set the yum source file http.repo for controller node and compute node respectively. After completion, submit the user name, password and IP address of the control node to the answer box.
