Build a DevStack Development Environment on CentOS7.0

Build a DevStack Development Environment on CentOS7.0

Yesterday, according to other people's information on the Internet, the local virtual machine was used to build a DevStack in the ubuntu14.04 environment and the mitaka version was selected. In the deployment phase of Eclipse, the blue screen of the host causes failure. Sang Xin...

I am not familiar with Ubuntu to build this environment again today. I have to check the information for many operations. Try a familiar centos system today and it should be easier to operate. Because you need to install the development tool (Eclipse), choose to install the desktop when installing the operating system. Hope you can install it successfully today...

Centos7 is installed with the KDE graphic interface.

First, set the network and host name. In this case, my virtual machine uses vmware workstation and nat network, and the host name is set to devstack.

My Network Configuration

To install devstack, you need to ensure that the virtual machine can access the Internet. This address is also required for later configuration. dhcp allocation is not recommended.

Modify host name

Okay, please ignore the wrong commands. I can't remember them. I tried them several times and finally got it right. Yes

Hostnamectl set-hostname Host Name

Restart once, and these changes will be updated.

After restarting, you can see that the host name is updated and the address is changed.

Finally, I can use the terminal software to log on.

Modify the host file.

Vim/etc/hosts

The font of the terminal software is really much more beautiful.

The source will be updated later, and yum update will be used. This process will take a long time ......

Input Y

Update completed

Now, devstack is officially installed. First install Git

Yum install git-y

Installation Complete

Next, download devstack. I chose to download it to/tmp/devstack. This directory will be used by the stack users at last, so it doesn't matter which directory to store it.

Download devstack and run the following command:

Git clone-B stable/mitaka https://git.openstack.org/openstack-dev/devstack

After the download is complete, go to the tools in the devstack directory and run

Create-stack-user.sh

Script to create a stack user. devstack must be used for operations.

After the user is created, run

Su-stack

Go to the stack user and copy the devstack directory to the stack user directory.

Modify the owner group of the devstack directory.

Chown-R stack: stack devstack

Before the formal installation, You can manually download the source code back to shorten the installation time. I have no comparison and doubt this.

You can run the following commands in multiple Windows:

Git clone-B stable/mitaka git: // git.openstack.org/openstack/horizon.git/opt/stack/horizon
Git clone-B stable/mitaka git: // git.openstack.org/openstack/keystone.git/opt/stack/keystone
Git clone-B stable/mitaka git: // git.openstack.org/openstack/nova.git/opt/stack/nova
Git clone-B stable/mitaka git: // git.openstack.org/openstack/neutron.git/opt/stack/neutron
Git clone-B stable/mitaka git: // git.openstack.org/openstack/glance.git/opt/stack/glance
Git clone-B stable/mitaka git: // git.openstack.org/openstack/cinder

Note that every terminal must be su-applied to the stack before execution.

Just like this

Execute a git clone command in each window.

After all the terminals are cloned, start to configure the configuration file. This is a key part of devstack installation. The configuration file determines the installed component content and network settings. Here I use the Mr _ portable configuration. The link is as follows: http://blog.csdn.net/u011521019/article/details/41014681.

In configuration, I only modified the network part, but the other parts were not changed.

In the devstack directory, create local. conf

Vim local. conf

Stick the configuration above.

Then you can start the installation and execute

./Stack. sh

Installation started, and it was a long wait .......

After lunch and taking a nap, I didn't fall asleep. I stared at the screen for a while and finally finished the installation.

Installation started at nine o'clock A.M. and completed at noon. It took three and a half hours and no development tools were installed.

In this case, you can use the web to open the firewall. Check if the firewall is disabled. My firewall is not closed at the beginning. It does not seem to work after it is installed. I cannot access the dashboard outside, but it can be accessed on the centos system. The interface is like this:

Admin Login

It should be normal, but external access is not allowed.

Next, install eclipse. First upload jdk

Decompress the tar.gz package of JDK to/usr/lib/Java.

Configuration file/etc/profile

Add JAVA_HOME

Exprot JAVA_HOME =/usr/lib/java/jdk directory

Run after editing

Source/etc/profile

Execute Command

Java-version

Verify that jdk can be used

Then upload eclipse. The idea can be downloaded. Now I can only install it using install.

Decompress eclipse installer

Tar-xzvf eclipse-inst-linux64.tar.gz

Then go to the centos graphical interface and start the installation.

Enter Installation Options

I selected the first

Select the installation path. The default setting is good.

Start installation, or wait...

In the middle of the pop-up license confirmation, just agree.

Installation Complete

Start eclipse and set the working directory to/opt/stack.

Install pydev. Open the following URL in the browser:

Https://marketplace.eclipse.org/content/pydev-Python-ide-eclipse

Click install and drag it to eclipse to start installation.

Select "Install" and click "confirm" to start installation.

After the installation is complete, you will be prompted to restart eclipse and click restart.

After startup, click windows> prefrences and find the python option.

Click "Quick Auto-Config"

Click "OK"

Click "File" and select "Import ..."

Select Projects from Git

Select an existing database

Select a component and click finish.

Here you can select Import as general project

This completes. You can see that the source code of keystone has been imported, and you can edit and modify it. Other components can also be imported in this way. At this point, the establishment of the devstack development environment is basically complete. With the code, we can solve problems and change the environment. Mom no longer needs to worry about the failure of openstack.

Finally, the problem of external access is also solved. The reason is that I used the systemctl stop firewalld command to disable the firewall. In fact, iptables still works, so I disabled iptables and the access was normal, I don't know how many centos firewalls are.
