Today, I would like to share with you how to use packstack to install openstack under centos. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Summary:

Prerequisites: the system requires two hard drives and two network cards.

Configure the network card and skip this step if the system is already connected to the Internet

Vi / etc/sysconfig/network-scripts/ifcfg-eth0; modify onboot=yes; service network restart

Install wget, skip this step if it is already installed

Yum install wget-y

Partitions for cinder-volumes

Fdisk / dev/sdb; n p 1 ret ret w; vgcreate cinder-volumes / dev/sdb1

Modify update source

Enable NetEase's centos update source

Cd / etc/yum.repo.d/; wget http://mirrors.163.com/.help/centos6-base-163.repo; mv centos-base.repo centos-base.repo.bak; mv centos6-base-163.repo centos-base.repo

Enable update source for openstack

Vi openstack.repo

Enter the following and save:

[openstack] baseurl= http://rdo.fedorapeople.org/openstack/openstack-grizzly/epel-6 gpgcheck=0

Update yum Feed

Yum clean all; yum makecache; yum update

Install packstack

Yum install-y openstack-packstack

Next, you need to enter your ip address with one click to install the openstack,--install-hosts parameter

Packstack-when prompted by install-hosts=your_ip;, enter your password and wait for the installation to complete.

Text

The simplest installation of openstack here refers to a centos system that requires the least number of steps to install. If the environment is unlimited, the simplest installation is to use stackops, which is an integrated ubuntu system with openstack. After installing the iso image it provides, openstack has been installed.

However, since many companies use centos as their primary operating environment, the simplest installation is as outlined in this article. Note that it must be a 64-bit centos, and it can be installed at its simplest. A 32-bit system will fail because some installation packages are missing.

One, download

Download link: download centos-6.4-x86_64-minimal.iso.

Download address collection of all centos versions: / / www.jb51.net/os/redhat/395751.html.

Second, install the virtual machine:

Create a new virtual machine with the configuration shown in the following figure. The key is that you need two hard drives and two network cards.

One of the network cards is nat and the other is host-only (uncertain). Otherwise, subsequent installation of packstack will fail.

Select the right arrow of the first hard inventory here.

It will be finished soon.

Third, configure the ip address

There is no ip after the installation.

Vi / etc/sysconfig/network-scripts/ifcfg-eth0

It can be configured as dhcp or static ip, as in the original.

Then restart the network service. Service network restart can see that there is an ip address.

Fourth, add an update source

Cd / etc/yum.reops.d/

Under minimum installation, you don't even have wget, so you need to install it. If you install dvd, ignore this step.

Yum install wget

Download NetEase's mirror repo file, or you can download other repo files according to your network situation.

Wget http://mirrors.163.com/.help/centos6-base-163.repo mvcentos-base.repocentos-base.repo.bak mvcentos6-base-163.repocentos-base.repo

Add openstack.repo

Vi openstack.repo

Enter the following

[openstack] baseurl= http://rdo.fedorapeople.org/openstack/openstack-grizzly/epel-6 gpgcheck=0

Then enter the command to update the source:

Yum clean all yum makecache yum update

Fifth, hard disk operation

Then partition and mount the disk:

Fdisk / dev/sdb n p 1 return (enter) retrun (enter) w

Operate on hard disk / dev/sdb1

Enter:

Vgcreate cinder-volumes / dev/sdb1

This step does not require the installation of cinder. See the following prompt to indicate that the operation is successful: volume group "cinder-volumes" successfully created

Sixth, install packstack

Yum install-y openstack-packstack

Seventh, use packstack to install openstack

Packstack-install-hosts=192.168.8.142

The next step is to enter the password of your root account

As you can see, a series of installations have taken place.

Eight, the installation is successful

Nine, log in to dashboard and manage openstack

Follow the above instructions, log in, and you can manage openstack.

In this step, if you use a vbox virtual machine, you need to configure it according to the way that the virtualbox virtual machine accesses the Internet and hosts and hosts visit each other-- organize this post. At this time, you enter not the address of the nat network card (eth0) that accesses the external network, but the address of the host-only network card (eth1). Because in vbox, the communication between the host and the virtual machine is accomplished through the host-only network card.

The username and password are saved in the keystonerc_admin file in the root directory and viewed using the cat command:

Cat / root/keystonerc_admin

Command line: source / root/keystonerc_admin can import some environment parameters

Then execute some commands, such as:

Keystone user-list

Create a normal user
