搭建openstack可以这么简单_centos8.5系统使用kolla部署openstack-优快云博客

基于kolla-ansible 部署openstack Yoga版本用于开发测试，本文绝对是目前为止最简单部署的了，请看完全文。

角色	网络	备注
部署机	eth0:10.10.1.115	一个普通docker容器
控制节点	eth0:10.14.203.171	至少一个网卡
计算节点	eth0:xxx eth1: trunk模式	大于等于两个网卡

一、部署kolla-ansible

这里在部署机 10.10.1.115 上部署了 kolla-ansible，这里基于docker起了个centos8 x86_64的容器，省事还好迁移

1. 安装kolla-ansible

启动kolla deploy容器, 用于部署以及后续迁移

#docker run -it --privileged --network host -h KOLLA_DEPLOY --name kolla_deploy -v /data:/data:rw centos:8
#使用aliyun centos8 base/epel repo （忽略）

#yum -y install gcc gcc-c++ make cmake python3-pip openssl-devel python3-devel wget openssh-clients rsync git
#yum update
#rm -rf /etc/yum.repos.d/*Linux*
#yum update libmodulemd
#dnf -y install gcc zlib* libffi-devel

升级pip源

#mkdir /root/.pip
#vim /root/.pip/pip.conf
    [global]
    timeout = 6000
    index-url = https://mirrors.aliyun.com/pypi/simple/
    trusted-host = mirrors.aliyun.com
#pip3 install -U pip

安装kolla-ansible，kolla 版本与 openstack 版本对应关系

#pip3 install ansible==4.10.0
#pip3 install 'ansible-core==2.11.12'
#pip3 install kolla-ansible==14.0.0

安装kolla-ansible依赖，这块kolla-ansible改动较大，社区将公共的部分插件、role等拆分出去了

#vim /usr/loca/share/kolla-ansible/requirements.yml  #变更collections地址,社区tag不存在了
    ---
    collections:
      - name: https://jihulab.com/james-curtis/ansible-collection-kolla
        type: git
        version: stable/yoga
        
#kolla-ansible install-deps
#不然报错 RROR! Failed to switch a cloned Git repo `https://opendev.org/openstack/ansible-collection-kolla` to the requested revision `stable/yoga`.

安装sshpass，默认centos8 没有yum包，需要源码安装

#wget https://sourceforge.net/projects/sshpass/files/latest/download -O sshpass.tar.gz
#cd ssh-pass-1.10
#./configure
#make
#make install

2. 配置kolla-ansible

#mkdir /etc/kolla
#cp -rf /usr/local/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/
#cp -rf /usr/local/share/kolla-ansible/ansible/inventory/* /etc/kolla/

优化ansible 性能

#mkdir /etc/ansible
#vim /etc/ansible/ansible.cfg
[default]
host_key_checking=False
pipelining=True
forks=100

测试ansible

# /usr/local/bin/ansible -i /etc/kolla/all-in-one all -m ping

生成openstack组件密码，该操作会填充/etc/kolla/passwords.yml

#kolla-genpwd

#vim /etc/kolla/globals.yml
    # Kolla options

    kolla_base_distro: "centos"
    kolla_install_type: "source"
    openstack_release: "yoga"
    kolla_internal_vip_address: "10.14.203.171"

    # Docker options
    # docker_registry: "registry.cn-beijing.aliyuncs.com"
    # docker_namespace: "kollaimage"
	openstack_logging_debug: "True"
	enable_openstack_core: "yes"
    # Neutron - Networking Options
    network_interface: "eth0"
    neutron_external_interface: "eth1"
    neutron_plugin_agent: "openvswitch"
    enable_neutron_provider_networks: "yes"

    # OpenStack services
    enable_cinder: "yes"
    enable_ironic: "yes"

3. 部署openstack

配置inventory清单 multinode，再部署服务

#cd /etc/kolla/
#vim multinode

#/usr/local/bin/kolla-ansible -i ./multinode bootstrap-servers
#/usr/local/bin/kolla-ansible -i ./multinode prechecks
#/usr/local/bin/kolla-ansible -i ./multinode pull
#/usr/local/bin/kolla-ansible -i ./multinode deploy
#/usr/local/bin/kolla-ansible -i ./multinode post-deploy
