CentOS Linux release 7.8.2003 (Core)
Python 2.7.5
pip 20.2 from /usr/lib/python2.7/site-packages/pip (python 2.7)
Python3 3.5.9
pip3 -V
pip 20.2 from /usr/local/python3/lib/python3.5/site-packages/pip (python 3.5)
git version 1.8.3.1
[root@localhost ~]# tox --version
3.18.0 imported from /usr/lib/python2.7/site-packages/tox/__init__.pyc
horizon 14.1.0 (rocky)
git clone https://git.openstack.org/openstack/horizon -b stable/rocky --depth=1 cd horizon
tox -l #查看horizon项目需要的环境列表
[root@localhost horizon]# tox -l
pep8
py27
py35
py3-dj111
releasenotes
npm
因horizon项目需要安装的依赖包较多，国内的朋友强烈建议使用国内pip源
mkdir ~/.pip
vim ~/.pip/pip.conf
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = https://pypi.tuna.tsinghua.edu.cn可能会有包缺失，也可以使用其他几个
https://pypi.doubanio.com/simple
http://mirrors.aliyun.com/pypi/simple/
可以先运行
tox -e runserver 试一下，多数情况下会失败，因为需要装的包太多了，所以我们要分步安装
yum install nss-devel nspr-devel -y
yum install -y libvirt-devel
yum -y install gcc intltool gperf glib2-devel libcap-devel xz-devel
yum -y install systemd-devel libsystemd-dev
git clone https://github.com/openstack/liberasurecode
cd liberasurecode
./autogen.sh
./configure
make
make test
make install
cd horizon
pip install -r requirements.txt
pip install -r test-requirements.txt
pip install -r upper-constraints.txt
项目中没有包含upper-constraints.txt文件，而是从
https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/rocky 读取，为提高安装速度将其下载至本地。
*安装过程中有很多无法删除和版本不兼容问题，基本可以用下面的办法解决
a、版本不兼容问题
pip install -I 包名称==所需版本
例如：
Failed to build pyeclib
ERROR: tox 3.18.0 has requirement pluggy>=0.12.0, but you'll have pluggy 0.6.0 which is incompatible.
pip install -I pluggy==0.12.0 -i https://pypi.doubanio.com/simple
b、无法自动删除问题
用find命令找到无法删除的包文件，用rm命令直接删除，然后继续安装，例如：
ERROR: Cannot uninstall 'subprocess32'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
[root@localhost horizon]# find / -name subprocess32*
/root/.cache/pip/wheels/f8/8f/c3/8c6f9ac94ec272e4936840f14edb2128551136cd0a8dbf49d6/subprocess32-3.5.2-cp27-cp27mu-linux_x86_64.whl
/usr/lib64/python2.7/site-packages/subprocess32-3.2.6-py2.7.egg-info
[root@localhost horizon]# rm /usr/lib64/python2.7/site-packages/subprocess32-3.2.6-py2.7.egg-info
rm：是否删除普通文件 "/usr/lib64/python2.7/site-packages/subprocess32-3.2.6-py2.7.egg-info"？y
cp openstack_dashboard/local/local_settings.py.example openstack_dashboard/local/local_settings.py vim openstack_dashboard/local/local_settings.py
