使用Kolla部署Stein版本OpenStack（含Ceph存储部分）
并于Kolla的介绍这里不进行过多的阐述，网上有很多文档。本文主要是针对最新版本的Kolla，解决单节点无法部署ceph-osd问题（在测试时发现多节点也无法部署Ceph-osd）。在最新版本的kolla中，官网已经给出要下架Ceph的公告，具体信息如下图：
此片文章会通过修改kolla-ansible源码解决不能部署ceph问题。
部署具体过程如下：

[root@openstack ~]# yum install ansible4.2 配置ansible
[root@openstack ~]# vim /etc/ansible/ansible.cfg
[defaults]
host_key_checking=False
pipelining=True

5.1 安装依赖
kolla分为两个仓库，一个为https://github.com/openstack/kolla , 另一个为https://github.com/openstack/kolla-ansible 在这两个仓库中有requirements.txt文件，需要将其中的依赖安装

[root@openstack ~]# pip install GitPython==3.0.2安装第二个依赖
[root@openstack ~]# pip install -r 2.txt5.2 安装kolla-ansible
[root@openstack ~]# pip install kolla-ansible在安装kolla-ansible的时候会出现下面的错误

[root@openstack ~]# pip install kolla-ansible --ignore-installed PyYAML5.3 安装kolla
[root@openstack ~]# pip install kolla6. 配置kolla-ansible
6.1 创建kolla目录，复制globals.yml，passwords.yml
[root@openstack ~]# mkdir -p /etc/kolla/
[root@openstack ~]# cp /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/6.2 由于此环境在虚拟机部署，所以virt_type的类型设置为qemu
[root@openstack ~]# mkdir -p /etc/kolla/config/nova/
[root@openstack ~]# vim /etc/kolla/config/nova/nova-compute.conf
[libvirt]
virt_type = qemu
cpu_mode = none6.3 配置ceph.conf，设备ceph副本数，此环境为一台节点，3个OSD盘，设置副本为1即可，如果是三台节点，9OSD盘，副本为3。
[root@openstack ~]# vim /etc/kolla/config/ceph.conf

注：如果此环境所在的网络中还有其它使用Kolla部署的openstack，那么需要修改globals.yml中的

在部署的过程中，我们可以看到在执行ceph-osd相关任务时，没有正确执行的反馈，具体如上图。此时我们可以通过ceph osd tree 命令来查看

7.6 生成admin-openrc.sh
[root@openstack ~]# kolla-ansible post-deploy7.7 上传镜像
ceph作为glance存储，镜像格式要使用raw，操作如下
[root@openstack ~]# yum install qemu-img -y
[root@openstack ~]# qemu-img convert -f qcow2 -O raw cirros-0.3.4-x86_64-disk.img cirros.raw

[root@openstack ~]# glance image-create --name cirros --disk-format raw --container-format bare --progress < cirros.raw

10. 测试openstack
10.1 上传镜像
[root@openstack ~]# kolla-ansible post-deploy
[root@openstack ~]# source /etc/kolla/admin-openrc.sh
[root@openstack ~]# glance image-create --name cirros --disk-format raw --container-format bare --progress < cirros.raw
