kolla-ansible部署openstack allinone单节点

环境准备

2 network interfaces

8GB main memory

40GB disk space

1.修改hostname

hostnamectl set-hostname kolla

2.配置域名解析

echo '10.1.10.161    kolla' >> /etc/hosts

Install packages

1.安装依赖

yum install python-devel libffi-devel gcc openssl-devel libselinux-python -y

2.安装 pip，ansible

##如果无法安装python-pip,先导入epel源
yum install epel-release -y
yum install python-pip ansible -y
pip install -U pip

安装 docker-ce（CentOS 7 使用 yum 进行安装）

# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新并安装Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 开启Docker服务
systemctl enable docker;systemctl restart docker

3.配置 docker 镜像加速

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}
EOF
systemctl daemon-reload;systemctl restart docker

4.安装 kolla-ansible

pip install kolla-ansible

##ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall
##出现报错不能卸载PyYAML，使用下面命令，忽略PyYAML错误
pip install kolla-ansible --ignore-installed PyYAML
 
mkdir -p /etc/kolla
chown $USER:$USER /etc/kolla

##Copy globals.yml and passwords.yml
cp -r /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla
##Copy all-in-one and multinode inventory files
cp /usr/share/kolla-ansible/ansible/inventory/* .

Prepare initial configuration

1.Configure Ansible /etc/ansible/ansible.cfg

[defaults]
host_key_checking=False
pipelining=True
forks=

2.配置主机清单文件，根据部署场景，这里选择 all-in-one 文件

[control]
kolla
[network]
kolla
[compute]
kolla
[storage]
kolla
[monitoring]
kolla
[deployment]
kolla

3.对 /etc/kolla/passwords.yml 文件生成随机密码，或者修改为自定义密码

kolla-genpwd
 
vim /etc/kolla/passwords.yml
##admin密码可以修改为自定义，在登录dashboard会用到
keystone_admin_password: 1234qwer

4.配置 /etc/kolla/globals.yml 文件

kolla_base_distro: "centos"
kolla_install_type: "source"
openstack_release: "train"
kolla_internal_vip_address: "10.1.10.161"
network_interface: "ens32"
neutron_external_interface: "ens34"
enable_haproxy: "no"
nova_compute_virt_type: "qemu"

5.配置 ssh 无密钥登录，授权节点

ssh-keygen
ssh-copy-id -i ~/.ssh/id_rsa.pub root@kolla

Deployment

##检查主机连接
ansible -i all-in-one all -m ping
##检查Bootstrap servers依赖
kolla-ansible -i ./all-in-one bootstrap-servers
##检查配置
kolla-ansible -i ./all-in-one prechecks
##pull镜像
kolla-ansible pull -i ./all-in-one
##执行部署
kolla-ansible -i ./all-in-one deploy

报错1：

执行kolla-ansible -i ./all-in-one bootstrap-servers

TASK [baremetal : Generate /etc/hosts for all of the nodes] ********************************************************************************************************************************
fatal:

to retry, use: --limit @/usr/share/kolla-ansible/ansible/kolla-host.retry

解决办法：

yum upgrade -y

更新的软件包如图

报错2：

执行kolla-ansible -i ./all-in-one prechecks

TASK [prechecks : Checking Docker version] *************************************************************************************************************************************************
fatal:

String: {% if result is failed or result.stdout |

to retry, use: --limit @/usr/share/kolla-ansible/ansible/site.retry

解决办法：

同上，更新软件包后一并解决

报错3：

执行kolla-ansible -i ./all-in-one prechecks

TASK [cinder : Checking LVM volume group exists for Cinder] ********************************************************************************************************************************
fatal:

解决办法：

报错没错找到cinder-volumes卷
手动创建

pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb

详细方法参考：https://www.cnblogs.com/omgasw/p/12098312.html

Using OpenStack

1.安装CLI客户端

pip install python-openstackclient

2.生成环境脚本

kolla-ansible post-deploy . /etc/kolla/admin-openrc.sh

报错4：

/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.25.7) or chardet (2.2.1) doesn't match a supported version

pip uninstall urllib3
pip uninstall chardet
pip install --upgrade requests

https://www.cnblogs.com/omgasw/p/12054988.html

报错5：

ImportError: cannot import name decorate

sed -i '/^from decorator import decorate/s/from/#from/' /usr/lib/python2./site-packages/dogpile/cache/region.py

https://www.cnblogs.com/omgasw/p/12054817.html

3.使用脚本文件初始化运行环境

/usr/share/kolla-ansible/init-runonce

4.删除部署的openstack环境

kolla-ansible destroy -i all-in-one --yes-i-really-really-mean-it
