查看hostname

[root@nova1 ~]# cat /etc/hostname 
nova1

配置pip源，方便下载python

[root@nova1 ~]# mkdir ~/.pip
[root@nova1 ~]# vim ~/.pip/pip.conf
[global]
index-url = https://mirrors.aliyun.com/pypi/simple/

[install]
trusted-host=mirrors.aliyun.com

配置网卡

[root@nova1 ~]# cd /etc/sysconfig/network-scripts/
[root@nova1 network-scripts]# cp ifcfg-ens33  ifcfg-ens37        
[root@nova1 network-scripts]# vim ifcfg-ens37
NAME="ens37"
DEVICE="ens37"
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
[root@nova1 network-scripts]# systemctl restart network

安装基础包和docker服务

1，安装基础包

[root@nova1 ~]# yum install -y python-devel libffi-devel gcc openssl-devel libselinux-python git python-pip
[root@nova1 ~]# wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
[root@nova1 ~]# python get-pip.py
[root@nova1 ~]# pip install -U pip
[root@nova1 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 

2,安装docker

[root@nova1 ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@nova1 ~]# yum -y install docker-ce 

3,设置docker volume挂载卷方式

[root@nova1 ~]# mkdir /etc/systemd/system/docker.service.d
[root@nova1 ~]# tee /etc/systemd/system/docker.service.d/kolla.conf << 'EOF'
> [Service]
> MountFlags=shared
> EOF

4，设置docker镜像加速

[root@nova1 ~]# mkdir /etc/docker/
[root@nova1 ~]# vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://1me84w5g.mirror.aliyuncs.com"]
}
[root@nova1 ~]# systemctl daemon-reload
[root@nova1 ~]# systemctl restart docker
[root@nova1 ~]# systemctl enable docker

安装kolla-ansible

安装ansible

[root@nova1 ~]# pip install 'ansible<2.10'

安装kolla-ansible train版本

[root@nova1 ~]# git clone https://github.com/openstack/kolla-ansible.git -b stable/train

安装kolla-ansible所需要的包

[root@nova1 ~]# cd kolla-ansible/
[root@nova1 kolla-ansible]# pip install pbr
[root@nova1 kolla-ansible]# pip install .
[root@nova1 kolla-ansible]# ls etc/kolla/
globals.yml  passwords.yml
[root@nova1 kolla-ansible]# cp -r etc/kolla/ /etc/kolla
[root@nova1 kolla-ansible]# ls /etc/kolla/
globals.yml  passwords.yml
[root@nova1 kolla-ansible]# ls ansible/inventory/
all-in-one  multinode
[root@nova1 kolla-ansible]# cp ansible//inventory/* /etc/kolla/
[root@nova1 kolla-ansible]# ls /etc/kolla/
all-in-one  globals.yml  multinode  passwords.yml

自定义kolla-ansible安装openstack的相关配置文件

1、自动生成openstack各服务的密码文件

[root@nova1 kolla-ansible]# kolla-genpwd 
[root@nova1 kolla-ansible]# vim /etc/kolla/passwords.yml 
改：keystone_admin_password: vN3viBr7DOkXPKzxqaNla8BkJrPXsJZSRTze6ODR
为：keystone_admin_password: admin

2、编辑 /etc/kolla/globals.yml 自定义openstack中部署事项

[root@nova1 kolla-ansible]# vim  /etc/kolla/globals.yml 
改：#kolla_base_distro: "centos"
为：kolla_base_distro: "centos"
改：#kolla_install_type: "binary"
为：kolla_install_type: "binary"
改：#openstack_release: "train"
为：openstack_release: "train"
改：kolla_internal_vip_address: "10.10.10.254"
为：kolla_internal_vip_address: "192.168.201.133"
改：#network_interface: "eth0"
为： network_interface: "ens33"
改：#neutron_external_interface: "eth1"
为： neutron_external_interface: "ens37"
改：#enable_haproxy: "yes"
为：enable_haproxy: "no"

开始基于kolla-ansible部署openstack

生成SSH Key，并授信本节点

[root@nova1 kolla-ansible]# ssh-keygen 
[root@nova1 kolla-ansible]# ssh-copy-id -i ~/.ssh/id_rsa.pub root@nova1

配置单节点清单文件

[root@nova1 kolla-ansible]# vim /etc/kolla/all-in-one   #vim命令行模式依次执行以下两条命令
:1,$s/localhost/nova1/
:1,$s/ansible_connection=local//  

开始部署OpenStack
1、安装依赖项目

[root@nova1 kolla-ansible]# kolla-ansible -i /etc/kolla/all-in-one  bootstrap-servers

执行部署检测

[root@nova1 kolla-ansible]# kolla-ansible -i /etc/kolla/all-in-one  prechecks

开始部署

[root@nova1 ~]# kolla-ansible -i /etc/kolla/all-in-one deploy

部署完成

验证部署

[root@nova1 ~]# kolla-ansible post-deploy  /etc/kolla/all-in-one 

验证部署完成后就创建了/etc/kolla/admin-openrc.sh 文件
