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 '10.1.10.151    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，docker-ce

yum install python-pip ansible docker-ce -y
pip install -U pip
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
pip install kolla-ansible --ignore-installed

mkdir -p /etc/kolla
chown $USER:$USER /etc/kolla

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

Prepare initial configuration

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

[defaults]
host_key_checking=False
pipelining=True
forks=100

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]
#localhost       ansible_connection=local
kolla
[network]
#localhost       ansible_connection=local
kolla
[compute]
#localhost       ansible_connection=local
kolla
[storage]
#localhost       ansible_connection=local
kolla
[monitoring]
#localhost       ansible_connection=local
kolla
[deployment]
#localhost       ansible_connection=local
kolla

检查主机连接

ansible -i all-in-one all -m ping

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
keystone_admin_password: 1234qwer

4.配置 /etc/kolla/globals.yml 文件

kolla_base_distro: "centos"
kolla_install_type: "source"
openstack_release: "stein"
kolla_internal_vip_address: "10.1.10.151"
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

kolla-ansible -i ./all-in-one bootstrap-servers　　　　##Bootstrap servers依赖
kolla-ansible -i ./all-in-one prechecks　　　　##检查配置
kolla-ansible pull -i ./all-in-one　　　　##pull镜像
kolla-ansible -i ./all-in-one deploy　　##部署

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

3.使用脚本文件初始化运行环境

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