Compile and install openstack mitaka horizon

    Since the version of the rpm package of openstack is too low, if there is a bug, you can only manually compile and install the new version of horizon.

    For specific bugs, please see BUG Security group not found for project in the dashboard of the openstack mitaka version . If you encounter such a problem, congratulations first, there is already a solution. I've been troubleshooting this for three weeks, you don't need to spend three weeks.

    Prerequisite: There must be another server with the same operating system as the controller, otherwise, you need to download the dependency package when compiling, which will damage the configured system.

1. Add stack development user
   

     sudo adduser stack

      sudo tee <<<"stack ALL=(ALL) NOPASSWD: ALL" /etc/sudoers

      groupadd stack
      useradd -g stack  -m stack

      sudo su --stack

2. Download devstack, the development environment of openstack

git clone https://git.openstack.org/cgit/openstack-dev/devstack

git branch -a

  *master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/origin/stable/kilo
  remotes/origin/stable/liberty
  remotes/origin/stable/mitaka
  remotes/origin/stable/newton
  remotes/origin/stable/ocata

//Switch to your own version
git checkout -b stable/mitaka

In the devstack root directory, add a configuration file local.conf

[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

Initialize the development environment, you need to download and install more packages, the time is a bit long, just wait

./stack.sh

3. Download the source code of horizon, and compile and configure it

git clone git://git.openstack.org/openstack/horizon

git branch -a

#Switch to the corresponding version
git checkout stable / mitaka


sudo pip install -c http://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/mitaka .

cp openstack_dashboard/local/local_settings.py.example openstack_dashboard/local/local_settings.py

sudo ./run_tests.sh --compilemessages
sudo ./manage.py collectstatic
sudo ./manage.py compress --force

Or manually download the packaged version without downloading via git

Download the latest version 9.1.2 here. After downloading, you can unzip the source code and perform the following operations

sudo pip install -c http://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/mitaka .

cp openstack_dashboard/local/local_settings.py.example openstack_dashboard/local/local_settings.py

sudo ./run_tests.sh --compilemessages
sudo ./manage.py collectstatic
sudo ./manage.py compress --force

After packaging, send it to the server where the controller is located

tar czvf horizon.tar.gz horizon/ --exclude .git

4. Configure the new version of horizon on the controller server. The premise is that you have already installed the dashboard on the server through the command.

yum install openstack-dashboard

Unzip the source file

tar zxvf horizon.tar.gz

Add horizon.conf configuration file to httpd service

# backup original file
cp /etc/httpd/conf.d/openstack-dashboard.conf /etc/httpd/conf.d/openstack-dashboard.conf.bak

mv /etc/httpd/conf.d/openstack-dashboard.conf /etc/httpd/conf.d/horizon.conf

horizon.conf file content

WSGIDaemonProcess dashboard
WSGIProcessGroup dashboard

Execute in the /opt/horizon directory, otherwise all style files will not be found

sudo ./manage.py collectstatic
sudo ./manage.py compress --force

Modify /opt/horizon directory permissions and modify lo

chmod -Rv 775 /opt/horizon

Add and modify the local_settings.py configuration file according to the official documentation

cp /opt/horizon/openstack_dashboard/local/local_settings.py.example /opt/horizon/openstack_dashboard/local/local_settings.py
