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
export OS_USERNAME=admin
export OS_PASSWORD=admin
export OS_AUTH_URL=http://192.168.30.139:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
# . admin-openrc
# 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
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

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

# vim /etc/nova/nova.conf

4.登陆云主机控制台提示如下错误

Failed to connect to server (code: 1006)

原因:计算节点开启了防火墙、SELINUX，关闭后重启计算节点正常

5.云主机无法获取IP，提示如下:

Failed to allocate the network(s), not rescheduling.

原因:计算节点不支持硬件加速

# egrep -c '(vms|svm)' /proc/cpuinfo
0

解决:确定计算节点是否支持虚拟机的硬件加速

# egrep -c '(vmx|svm)' /proc/cpuinfo
0

注:

大于等于1:计算节点支持硬件加速且不需要额外的配置

0:计算节点不支持硬件加速,必须配置 libvirt 来使用 QEMU 去代替 KVM

# vim /etc/nova/nova.conf
[libvirt]
virt_type = qemu

6.上传云镜像失败，提示403 Forbidden

# openstack p_w_picpath create "cirros"  --file cirros-0.3.5-x86_64-disk.img   --disk-format qcow2 --container-format bare   --public
403 Forbidden
You are not authorized to complete publicize_p_w_picpath action.(HTTP 403)

原因:Glance镜像服务组件中未进行如下配置

[paste_deploy]
flavor = keystone

7.登陆云主机控制台提示:Booting from Hard Disk

这里是由于镜像损坏导致，重新下载换个镜像后即可正常进入系统。

4.nova服务配置完成后无法重新启动其中组件

# service nova-api restart
# service nova-consoleauth restart
# service nova-scheduler restart
# service nova-conductor restart             ##无法启动
