Oracle VM + centos7.1+openstack kilo 多結點安裝教程---keystone的安裝(2)

標籤：

聲明：最近在進行openstack的kilo版本的安裝，發現現有的網路教程非常少，而且多數教程並不能安裝成功，故寫此教程。openstack的安裝較為複雜，本教程並不能保證在不同環境下也能將其安裝成功。個人安裝教程，也難免出錯。同時，安裝是在虛擬機器環境下，真實安裝環境需要變更。

 第二部分 keystone的安裝 (2)

配置Apache服務

vim /etc/httpd/conf/httpd.conf

ServerName 一行改為ServerName controller

 建立檔案：

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

 寫入如下內容：

Listen 5000Listen 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>

建立目錄

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

  

賦權

 

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

  

啟動

systemctl enable httpd.servicesystemctl start httpd.service

 

（註：按照kilo版的安裝手冊，我在這裡遇到了無法啟動的問題，下面給出解決辦法，原因主要是Apache和keystone service 服務存在衝突，官方手冊建議使用Apache提供restful API 服務）：

 

檢驗是否存在問題

 設定環境變數：

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

註：openstack是上文中設定的欄位

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

註：我在此處遇到錯誤：HTTP 500 

 如下解決：

首先嘗試：

 

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

註：出現Failed to start OpenStack  Identity  Service 

 

解決辦法：

 

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

 然後啟動：

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

註：出現：Failed to start the Apache Http server

 

 最後嘗試：

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

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

啟動服務:

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

解決問題.
