编译安装openstack mitaka horizon

由于openstack的rpm包版本过低，有BUG只能自己手动编译安装新版本的horizon。

具体什么bug请看[url=http://powertech.iteye.com/blog/2363303]openstack mitaka版dashboard的BUG Security group not found for project [/url]，如查你也碰到这样的问题，先恭喜你，已经有解决办法了。我在这个问题上已经排查了三周，你就不需要花三周时间了。

前提条件：要有一台和controller一样操作系统的另一台服务器，否则编译时需要下载依赖包，会损坏已配好的系统。

1、添加stack开发用户

     sudo adduser stack

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

      groupadd stack 
      useradd -g stack  -m stack

      sudo su - stack

2、下载devstack，openstack的开发环境

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

//切换到自己用的版本
git checkout -b stable/mitaka

在devstack根目录，添加一个配置文件local.conf

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

初始化开发环境，需要下载和安装比较多的包，时间稍常，只需等待

./stack.sh

3、下载horizon的源码，并进行编译和配置

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

git branch -a

#切换到对应版本
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

或者手动下载打好的版本的包，不通过git下载

[quote]9.1.2 openstack/horizon ce80bb6fec3cb0262728e7ae8b9d695cf832e5bf
9.1.1 openstack/horizon 9a460aad76c05c411765af2b2d85b075a5f7004e
9.1.0 openstack/horizon 8211d685afed20469b5bfd53c008e4bc98e7047a

9.0.0 openstack/horizon 2eb320bd31078e3728b91e4badc597624d0827f8[/quote]

这里下载最新的版本9.1.2，下载后，可以解压源码，执行以下操作

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

打包后发到controller所在的服务器上

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

4、controller服务器上配置新版horizon，前题是你已经在该台服务器上通过命令安装过dashboard，

yum install openstack-dashboard

解压源文件

tar zxvf horizon.tar.gz

给httpd服务增加horizon.conf配置文件

#备份原文件
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文件内容

WSGIDaemonProcess dashboard
WSGIProcessGroup dashboard
WSGISocketPrefix run/wsgi

WSGIScriptAlias /dashboard /opt/horizon/openstack_dashboard/wsgi/django.wsgi
Alias /dashboard/static /opt/horizon/static

<Directory /opt/horizon/openstack_dashboard/wsgi>
  Options All
  AllowOverride All
  Require all granted
</Directory>

<Directory /opt/horizon/static>
  Options All
  AllowOverride All
  Require all granted
</Directory>

在/opt/horizon目录下执行，否则会找不到所有样式文件

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

修改/opt/horizon目录权限和修改lo

chmod -Rv 775 /opt/horizon

按官方文档添加和修改local_settings.py配置文件

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

重启服务器

systemctl restart httpd.service

访问控制面板即可
