Editor to share with you how to install packstack in CentOS. I hope you will get something after reading this article. Let's discuss it together.

The steps for CentOS to install version M are as follows:

Step 1: initial system configuration

1. Prepare before you start to deploy your own virtual cloud computing infrastructure with your root account, log in for the first time and make sure the system is the latest node.

two。 Next, identify, stop, disable, and delete unwanted services, mainly Postfix,NetworkManager and firewalld.

Turn off the firewall and NetworkManager

# systemctl stop postfix firewalld NetworkManager

Permanently shut down the firewall and NetworkManager

# systemctl disable postfix firewalld NetworkManager

# systemctl mask NetworkManager

# yum remove postfix NetworkManager NetworkManager-libnm

Prompt that if the uninstall is successful, it is completed.

3. Disable the SELinux policy on your computer entirely by issuing the following command. You can also edit the / etc/selinux/config file and set SELINUX from the screenshot below.

# setenforce 0

# getenforce

# vi / etc/selinux/config

Disable SELinux

Then restart the virtual machine

4. Set the hostname of your Linux system in the next step using the hostnamectl command. So change the FQDN variable.

# hostnamectl set-hostname cloud.centos.lan

Set the Linux system hostname

Step 2: install OpenStack in CentOS

5. Configure the OpenStack-Mitaka network source

Vi / etc/yum.repos.d/CentOS-OpenStack.repo

[OpenStack-Mitaka]

Name=OpenStack-Mitaka

Baseurl= http://vault.centos.org/7.2.1511/cloud/x86_64/openstack-mitaka/

Enabled=1

Gpgcheck=0

6. Install packstack tools

# yum install openstack-packstack libvirt-enablerepo=OpenStack-Mitaka

7.Packstack installation:

Performing the installation using the following code automatically configures the bridge:

Packstack-allinone-provision-demo=n-os-neutron-ovs-bridge-mappings=extnet:br-ex-os-neutron-ovs-bridge-interfaces=br-ex:eno16780032-os-neutron-ml2-type-drivers=vxlan,flat

Eno16780032 is the name of the network card

Note: if an error occurs, you need to re-execute step 7, but sometimes you will still report an error. It may be that you installed it before and did not uninstall it cleanly. At this time, do not worry. Uninstall the script for openstack components.
