環境准備
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.安裝依賴
yum install python-devel libffi-devel gcc openssl-devel libselinux-python -y
2.安裝 pip，ansible
##如果無法安裝python-pip,先導入epel源
yum install epel-release -y
yum install python-pip ansible -y
pip install -U pip
安裝 docker-ce（CentOS 7 使用 yum 進行安裝）
# step 1: 安裝必要的一些系統工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加軟件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新並安裝Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 開啟Docker服務
systemctl enable docker;systemctl restart docker
3.配置 docker 鏡像加速
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.安裝 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
##出現報錯不能卸載PyYAML，使用下面命令，忽略PyYAML錯誤
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=100
2.配置主機清單文件，根據部署場景，這里選擇 all-in-one 文件
[control] kolla [network] kolla [compute] kolla [storage] kolla [monitoring] kolla [deployment] kolla
3.對 /etc/kolla/passwords.yml 文件生成隨機密碼，或者修改為自定義密碼
kolla-genpwd vim /etc/kolla/passwords.yml ##admin密碼可以修改為自定義，在登錄dashboard會用到
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 無密鑰登錄，授權節點
ssh-keygen
ssh-copy-id -i ~/.ssh/id_rsa.pub root@kolla
Deployment
##檢查主機連接
ansible -i all-in-one all -m ping
##檢查Bootstrap servers依賴
kolla-ansible -i ./all-in-one bootstrap-servers
##檢查配置
kolla-ansible -i ./all-in-one prechecks
##pull鏡像
kolla-ansible pull -i ./all-in-one
##執行部署
kolla-ansible -i ./all-in-one deploy
- 報錯1：
執行kolla-ansible -i ./all-in-one bootstrap-servers

報錯沒錯找到cinder-volumes卷
手動創建
pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb

Using OpenStack
1.安裝CLI客戶端
pip install python-openstackclient
2.生成環境腳本
kolla-ansible post-deploy . /etc/kolla/admin-openrc.sh
- 報錯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/12054817.html
3.使用腳本文件初始化運行環境
/usr/share/kolla-ansible/init-runonce
4.刪除部署的openstack環境
kolla-ansible destroy -i all-in-one --yes-i-really-really-mean-it
