Openstack安装过程中遇到的问题汇总

Openstack安装过程中遇到的问题汇总安装过程中遇到的问题汇总

本文给大家分享的是作者在Centos7中安装openstack过程中出现的一些问题的汇总，以及解决的方法，有需要的小伙伴可以参考下

一、Centos7安装Mitika问题

1.问题:在keystone安装阶段请求认证令牌出现错误

# vim admin-openrc

export OS_PROJECT_DOMAIN_NAME=default

export OS_USER_DOMAIN_NAME=default

export OS_PROJECT_NAME=admin

# openstack token issue

The request you have made requires authentication. (HTTP 401) (Request-ID: req-7fdfe96b-ed63-4204-a357-ef104d9cf07d)

解决:该问题是由于二次实验时更改了用户密码，密码错误致使出现该问题，更改环境变量脚本的密码后，请求认证令牌成功

# vim admin-openrc

export OS_PROJECT_DOMAIN_NAME=default

export OS_USER_DOMAIN_NAME=default

export OS_PROJECT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=keystone

export OS_AUTH_URL=http://192.168.30.139:35357/v3

解决:更改dashboard的local_settings配置文件并重启httpd和memcached，刷新后可正常登陆，这是在国外的论坛上找到得解决方法。

# vim /etc/openstack-dashboard/local_settings

#SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

SESSION_ENGINE = 'django.contrib.sessions.backends.file'

# systemctl restart httpd memcached

# systemctl status httpd memcached

解决:nova.conf配置文件配置错误，仔细核对重新配置后正常
