完成安装
1.决定计算节点是否支持虚拟机的硬件加速：
[Bash shell] 纯文本查看 复制代码
|
1
|
egrep-c
'(vmx|svm)'/proc/cpuinfo
|
如果输出值是1或则比这更大，则不需要额外配置
如果是0，计算节点不支持硬件加速，你必须配置libvirt 为QEMU ，代替KVM
a. 编辑文件/etc/nova/nova-compute.conf在 [libvirt]
[Bash shell] 纯文本查看 复制代码
|
1
2
3
|
[libvirt]
...
virt_type
= qemu
|
2.重启计算服务
[Bash shell] 纯文本查看 复制代码
|
1
|
service
nova-compute restart
|
3.如果存在SQLite 数据，则删除
[Bash shell] 纯文本查看 复制代码
|
1
|
rm-f
/var/lib/nova/nova.sqlite
|
验证安装【控制节点】
1.生效环境变量
[Bash shell] 纯文本查看 复制代码
|
1
|
sourceadmin-openrc.sh
|
2.目录服务组件来验证每个进程的成功创建和注册：
[Bash shell] 纯文本查看 复制代码
|

|
nova
service-list
|
[Bash shell] 纯文本查看 复制代码
|

+----+------------------+------------+----------+---------+-------+----------------------------+-----------------+
|
Id | Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+----+------------------+------------+----------+---------+-------+----------------------------+-----------------+
|
1 | nova-conductor | controller | internal | enabled | up | 2014-09-16T23:54:02.000000 | - |
|
2 | nova-consoleauth | controller | internal | enabled | up | 2014-09-16T23:54:04.000000 | - |
|
3 | nova-scheduler | controller | internal | enabled | up | 2014-09-16T23:54:07.000000 | - |
|
4 | nova-cert | controller | internal | enabled | up | 2014-09-16T23:54:00.000000 | - |
|
5 | nova-compute | compute1 | nova | enabled | up | 2014-09-16T23:54:06.000000 | - |
+----+------------------+------------+----------+---------+-------+----------------------------+-----------------+
|
这个输出显示四个服务在控制节点启用，一个服务在计算节点
3.列出API endpoints 在 Identity service核实身份验证连接服务

遇到问题：
su -s /bin/sh -c "nova-manage db sync" nova
No handlers could be found for logger "oslo_config.cfg"
原因：
日志文件的配置项错误
解决办法：
修改logdir为log_dir=/var/log/nova
————————————————————————————————————
ERROR (EndpointNotFound): publicURL endpoint for compute service not found
原先endpoint被删除了
创建后：
总结：
在删除service的时候，endpoint会自动删除。他们之间是级联删除的
————————————————————————————————————
