测试环境
openEuler-22.03-LTS-SP4-x86_64-dvd.iso
Virtual Box，4 vCPU, 8G RAM, 50 vDisk。安装时删除/home，SWAP分区，全部空间给/目录。
目标是部署OpenStack All-In-One模式，控制节点+计算节点+存储节点在一台机器实现。
系统配置
常用工具
dnf install -y tar git
优化SSH
vi /etc/ssh/sshd_config
UseDNS no
systemctl restart sshd
关闭selinux
sed -i 's#SELINUX=enforcing#SELINUX=permissive#g' /etc/selinux/config
关闭防火墙
systemctl disable --now firewalld
systemctl stop firewalld
systemctl status firewalld
设置主机名，配置hosts文件
hostnamectl set-hostname node1
cat << EOF >> /etc/hosts
192.168.31.115 node1
EOF
设置免密登录
ssh-keygen
ssh-copy-id node1
重启系统
system reboot
安装docker
vi /etc/yum.repos.d/openEuler-docker-ce.repo
[docker-ce-stable]

gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg
dnf install -y docker-ce
指定docker加速器，阿里云申请免费
mkdir -p /etc/docker
tee /etc/docker/daemon.json << 'EOF'
{
"registry-mirrors": ["https://xxx.mirror.aliyuncs.com"]
}
EOF
systemctl daemon-reload
#启动docker服务
systemctl start docker
systemctl enable docker
systemctl status docker
docker info
docker --version
安装Python docker模块
pip3 install docker
安装ansible
更换pip国内源，加速pip下载安装
mkdir ~/.pip
vi ~/.pip/pip.conf
global
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
install
trusted-host = pypi.tuna.tsinghua.edu.cn
pip3 install ansible
ansible --version
安装后的版本是ansible-8.7.0 + ansible [core 2.15.12]
优化ansible
mkdir /etc/ansible
vi /etc/ansible/ansible.cfg
defaults
host_key_checking=False
pipelining=True
forks=100
安装kolla-ansible
安装kolla-ansible需要的依赖
dnf install -y python3-devel libffi-devel gcc openssl-devel python3-libselinux
安装kolla-ansible
kolla-ansible与OpenStack之间版本信息：https://docs.openstack.org/releasenotes/kolla-ansible/
pip3 install pbr
pip3 install kolla-ansible==17.5.0
kolla-ansible --version
从Yoga版本开始需要安装Ansible Galaxy的依赖项
kolla-ansible install-deps
部署OpenStack
创建kolla-ansible配置文件目录
mkdir /etc/kolla
chown U S E R : USER: USER:USER /etc/kolla
配置文件
cp /usr/local/share/kolla-ansible/etc_examples/kolla/globals.yml /etc/kolla/
cp /usr/local/share/kolla-ansible/etc_examples/kolla/passwords.yml /etc/kolla/
cp /usr/local/share/kolla-ansible/ansible/inventory/all-in-one /etc/kolla/
编辑all-in-one
sed -i 's#localhost ansible_connection=local#node1 ansible_python_interpreter=/usr/bin/python3#g' /etc/kolla/all-in-one
生成密码
kolla-genpwd
编辑globals.yml
cat /etc/kolla/globals.yml|grep -v ^#|grep -v ^$

部署安装指定版本库，避免报错。
pip3 install pyOpenSSL==24.2.1
pip3 install cryptography==42.0.0
pip3 install paramiko==3.0.0
已安装过docker，注释掉kolla自动安装docker的任务
vi /root/.ansible/collections/ansible_collections/openstack/kolla/roles/docker/defaults/ main.yml
enable_docker_repo: false
vi /root/.ansible/collections/ansible_collections/openstack/kolla/roles/docker/tasks/main.yml
