1. Configure virtual machines

2. Create virtual machines for control and compute nodes

Create two virtual machines ( Control node and calculation node )
2.1 Create node virtual machine
(1) Create a new system for the virtual machine , Set parameters


(2) After the node system is installed , Use root Account login system , Configure static ip Address

>ip a   //  Command to check that there is no network card at this time ip Address , Modify the interface of the corresponding network card ip Address 
> vi /etc/sysconfig/network-scripts/ifcfg-xxxxx  //  Use vi Command configuration network ip Address 
> systemctl restart network     //  Use systemctl Command to restart the network 

Be careful ： gateway Set to 192.168.200.2 What's the reason for that ？
Because the gateway has been set in the virtual machine network configuration ip and ip Address range , as follows ：

If you want the virtual machine to be able to access the Internet , Just add dns The configuration can be ：

(3) View configuration results

(4) > And then through secureCRT You can connect to the system shell Terminal interface ：

notes ： About secureCRT and SecureFX Software installation reference blog ：

(5) To configure Host name of control node controller and Compute node hostname compute
Sign in controller Node terminal , Enter the following command ：

>hostnamectl set-hostname controller
> logout
> vi /etc/hosts           //  Add the following 2 That's ok 

> ping compute         //  Test whether the host name is set successfully 
	 Sign in compute Node terminal , Enter the following command ：
>hostnamectl set-hostname compute
> logout
> vi /etc/hosts           //  Add the following 2 That's ok 

ping controller // Test whether the host name is set successfully
(6) Each node ( Control node and computing node at the same time ) Set up Turn off firewall , Start up does not start ; selinux by permissive
Enter the following command :
systemctl stop firewalld // Stop firewall
systemctl disable firewalld // Set to enable or disable the firewall
firewall-cmd --state // Test and check the firewall status
setenforce 0 // Temporarily Closed Selinux
vi /etc/selinux/config // Use vi command , Enter the configuration file and change it to disable

getenforce // getenforce Command to view test results

(7) Set the synchronization time
yum install -y chrony // Both the control node and the computing node execute the installation command

1. Configure the control node as shown in the figure : Comment out your own server Group . Add the following two lines ：
   
2. Configure the calculation node as shown in the figure :
   
3. Finally, start the service and start chronyd：（ Both the computing node and the control node should execute ）

> systemctl start chronyd
> systemctl enable chronyd

4. test
   Execute on the compute node chronyc sources -v Command synchronization time

>  chronyc sources
 For example, modify the server controller Time for , Check whether the calculation node is synchronized successfully :
> timedatectl set-time  "2021-07-31 20:40:38"            //  stay controller Node execution 
>  chronyc sources -v          //  stay compute Node execution 

3. Import centos\XianDian Image package

(1) Use SecureFX Software creates a new connection 192.168.100.10

(2) Use... On the control node SecureFX Software upload image file CentOS-7-x86_64-DVD-1511.iso and
XianDian-IaaS-v2.1.iso To /opt Under the path

（3） Configure the control node , Create two directories /opt/centos、/opt/iaas, Will be more than iso The image files are mounted in two directories respectively ：

> cd /opt
> mkdir iaas
> mkdir centos
> mount -o loop /opt/CentOS-7-x86_64-DVD-1511.iso /opt/centos/     // mount Centos 
> mount -o loop /opt/XianDian-IaaS-v2.2.iso /opt/iaas/                   // mount iaas

Be careful ： If the next installation process , Restart the computer , Then you need to download download Resource Pack , Need to re mount mount ！

4. To configure yum Source

4.1 Configure control node local yum Source file local.repo （ Reference resources /etc/yum.repos.d/ In the catalog yum Source configuration ）
(1) First clear the source configuration file or move repo File to media Catalog

mv /etc/yum.repos.d/* /media/ perhaps rm –rf /etc/yum.repos.d/*
(2) establish local.repo file , Configure source content
vi /etc/yum.repos.d/local.repo // Use vi Command edit control node yum Source

(3) Test configuration success
yum clean all
yum repolist // Use yum repolist Command to check whether the configuration is successful
(4) install vsftpd：

>yum -y install vsftpd
>vi /etc/vsftpd/vsftpd.conf         //  Edit profile , Add a row 
anon_root=/opt    //  Specify anonymous users to access the home directory 

systemctl restart vsftpd && systemctl enable vsftpd // Enter the restart command
adopt windows Computer Explorer , visit ftp website , Verify if ok？

(5) restart vsftpd service , see vsftp state ：

4.2 Configure the local configuration of the compute node yum Source file ftp.repo
(1) First clear the source configuration file or move repo File to media Catalog
mv /etc/yum.repos.d/* /media/ perhaps rm –rf /etc/yum.repos.d/*
(2) establish ftp.repo file , build ftp The server points to store yum The source path , Configure compute nodes yum Source file ftp.repo Use the previously configured control nodes ftp As yum Source （ The addresses of two nodes are represented by host names ）

> vi /etc/yum.repos.d/ftp.repo   //  Edit source file ftp.repo  Point to ftp The server , Add the following :

> yum clean all
> yum repolist             //  Use yum repolist Command to check whether the configuration is successful 

5. Modify the configuration file

Install the control node and the calculation node respectively iaas-xiandian package , Complete the configuration of basic variables in the configuration file . According to the following table 2 Complete the configuration of the specified variable :

(1) For configuration cinder Storage service , The virtual machine that needs to be in the computing node , New disk sdb, And partition it

After rebooting the system , Get into shell terminal , Use the command to partition

> fdisk /dev/sdb                    //  Partition sdb surface 
> n   Express  add a new partition
> w  Express write table to disk and exit  

(2) At the control node and calculation node , At the same time, use the command to install iaas Of rpm package

yum -y install iaas-xiandian // Install at the control node and the calculation node respectively iaas


(3) According to the above table 2 Complete the configuration of specified control node and calculation node variables ：( Refer to... In the attachment folder openrc.sh)
vi /etc/xiandian/openrc.sh // Edit environment variables

Specific document contents , Refer to the below ：



skill 1： In the step of editing environment variables , How to quickly remove the first in each line #？
vi /etc/xiandian/openrc.sh // Edit the environment variable and enter the following ：
:%s/^#//g

skill 2： have access to scp The command directly copies the configured file of the control node to the computing node .
scp /etc/xiandian/openrc.sh compute:/etc/xiandian/

6. install openstack package

The basic configuration operation command has been written as shell Script , One click installation through script .
If during the installation process , appear download Failure or failed to load perhaps no such file…. Here's the picture ：

Check the mount Two directories mounted /opt/centos and /opt/iaas Whether there is a file . If the directory is empty , You need to mount it again ： Execute the following two lines of commands ：

> mount -o loop /opt/CentOS-7-x86_64-DVD-1511.iso /opt/centos/     // mount Centos 
> mount -o loop /opt/XianDian-IaaS-v2.2.iso /opt/iaas/                   // mount iaas
