环境

我的规划

注意： 我的教程有很多错误，如果发现了错误请麻烦给我留个言

controller IP： 192.168.3.104（管理IP），192.168.101.131（提供者IP）
compute IP：192.168.3.103（管理IP），192.168.101.130（提供者IP）
密码全为： 123456

官方文档的配置：
comtroller IP： 10.0.0.11
compute IP： 10.0.0.31

技巧：
可以使用grep过滤要配置的文件，很多文件都是没有内容的，只有一个标签
grep -vE ‘^#|^$’ 文件路径

##配置进度
controller： glance节点已经配完
compute：配置以及全部配完

安全

controoler： openssl rand -hex 10 > rand.pass
官方文档建议admin使用这个命令生成的的字符串当密码

主机名，yum源等

所有节点:

hostnamectl set-hostname controller
hostnamectl set-hostname compute
yum -y install epel-release centos-release-openstack-stein 
yum -y install python-openstackclient openstack-selinux
yum  -y  upgrade
配置hosts文件
删除网卡配置文件中关于UUID和HWADDR的内容
检查时间是否一致date

NTP（可选）

问题集合

placement出错

openstack resource provider list 没有结果显示

解决：
对配置文件/etc/httpd/conf.d/00-placement-api.conf 添加内容：

再次运行openstack resource provider list 验证：

keystone出错

同步数据时日志报错
#su -s /bin/sh -c “keystone-manage db_sync” keystone

在知乎上查找到可能是/etc/hosts 文件的错误，但我hosts文件没问题（controler写的不是管理IP），我猜想是不是前面配置的时候写的是管理IP，而这里写的又不是管理IP，导致keystone查找IP出错，所以我把hosts文件的IP改为controller的管理IP，再次运行同步命令，这个就成功了。

原来的hosts文件，如下图

因为我controller的管理IP是192.168.10.150，然后keystone同步数据库时根据controller的解析找到第一个IP——192.168.101.150，导致出错；把第一行删掉或者换到下一行就可以解决这个问题

glance出错

配置完成后，上传镜像报服务器内部错误，查看glance日志发现好像数据库报错，但仔细看了数据库的配置貌似没有配错， 哪位仁兄发现哪里配错了麻烦留言一下

报错信息：
HTTP 500 Internal Server Error: The server has either erred or is incapable of performing the requested operation.

问题已解决：（同keystone数据库同步失败的原因一样）
尴尬：我原来hosts中controller的IP有两个，删除掉多余的，只留一个管理IP的映射，结果就不报错了

dashboard出错

创建网络时出现错误



原来我在配/etc/neutron/plugins/ml2/ml2_conf.ini时配错了，跟下面参考的网站的情况一样，配错地方了。

参考了：https://blog.csdn.net/ranweizheng/article/details/87857936?ops_request_misc=%25257B%252522request%25255Fid%252522%25253A%252522160837126416780273393490%252522%25252C%252522scm%252522%25253A%25252220140713.130102334…%252522%25257D&request_id=160837126416780273393490&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2_allsobaiduend~default-2-87857936.first_rank_v2_pc_rank_v29&utm_term=No%20tenant%20network%20is%20available%20for%20allocation.

还有一个错误是因为驱动的问题

有一个选型时type_driver，只有在里面有的驱动才能创建相应的网络

创建实例出错

1、Host ‘compute’ is not mapped to any cell

按照网上的教程：
nova-manage cell_v2 discover_hosts --verbose
再次创建实例貌似就没问题了

2、4336 ERROR nova.compute.manager [req-7c1bc64e-74da-4152-84fd-45eff53ed5ee 25b99096b60849e9b5a66dde8ce879cb dba851953a1446cfb651022214d6d486 - default default] [instance: ee763bf9-25ae-48e2-8a52-524695e9b4f1] Failed to allocate network(s): VirtualInterfaceCreateException: Virtual Interface creation failed

创建VM报错，同时网络是down的

我用vxlan网络创建VM成功创建并允许，但用Local创建就报这样的错，可能local配置的原因

3、There are not enough hosts available.

计算结点上创建的VM太多了

4、oslo.messaging._drivers.impl_rabbit [-] Unexpected error during heartbeat thread processing, retrying…错误
