声明：最近在进行openstack的kilo版本的安装，发现现有的网络教程非常少，而且多数教程并不能安装成功，故写此教程。openstack的安装较为复杂，本教程并不能保证在不同环境下也能将其安装成功。个人安装教程，也难免出错。同时，安装是在虚拟机环境下，真实安装环境需要进行更改。

第二部分 keystone的安装 (2)

配置Apache服务

vim /etc/httpd/conf/httpd.conf

ServerName 一行改为
ServerName controller

新建文件：

vim /etc/httpd/conf.d/wsgi-keystone.conf

写入如下内容：

Listen 5000
Listen 35357
 
<VirtualHost *:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-public
    WSGIScriptAlias / /var/www/cgi-bin/keystone/main
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    LogLevel info
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined
</VirtualHost>
 
<VirtualHost *:35357>
    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-admin
    WSGIScriptAlias / /var/www/cgi-bin/keystone/admin
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    LogLevel info
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined
</VirtualHost>

创建目录

mkdir - p /var/www/cgi-bin/keystone

curl http://git.openstack.org/cgit/openstack/keystone/plain/httpd/keystone.py?h=stable/kilo |
tee /var/www/cgi-bin/keystone/main /var/www/cgi-bin/keystone/admin

赋权

chown -R keystone:keystone /var/www/cgi-bin/keystone
chmod 755 /var/www/cgi-bin/keystone/*

启动

systemctl enable httpd.service
systemctl start httpd.service

（注：按照kilo版的安装手册，我在这里遇到了无法启动的问题，下面给出解决办法，原因主要是Apache和keystone service 服务存在冲突，官方手册建议使用Apache提供restful API 服务）：

检验是否存在问题

设置环境变量：

export OS_TOKEN=openstack 
export OS_URL=http://controller:35357/v2.0

注：openstack是上文中设置的字段

openstack service create --name keystone --description "Opentack Identity" identity

注：我在此处遇到错误：HTTP 500

如下解决：

首先尝试：

systemctl enable openstack-keystone.service
systemctl start openstack-keystone.service

注：出现Failed to start OpenStack Identity Service

解决办法：

ln -s /usr/lib/systemd/system/httpd.service /etc/systemd/system/openstack-keystone.service

然后启动：

systemctl enable openstack-keystone.service
systemctl start openstack-keystone.service

注：出现：Failed to start the Apache Http server

最后尝试：

vim /usr/lib/systemd/system/httpd.service

在Type下添加一行
PIDFile= /var/run/httpd/httpd.pid

启动服务:

systemctl enable openstack-keystone.service
systemctl start openstack-keystone.service

解决问题.
