红太狼 2023-02-12 13:24 61阅读 0赞

并于Kolla的介绍这里不进行过多的阐述，网上有很多文档。  
本文使用kolla安装最新版本Train  
部署具体过程如下：

### 1. 准备工作 ###

#### 1.1 安装Centos7.5系统，过程略。本人使用virtualbox创建虚拟机，使用两张网卡即可。第一张为管理网络，可以访问公网，第二张为实例使用网络，启动即可，无需配置IP。 ####

[root@openstack ~]# cat /etc/centos-release
    CentOS Linux release 7.5.1804 (Core)

#### 1.2 关闭防火墙、设置selinux ####

[root@localhost ~]# systemctl disable firewalld
    [root@localhost ~]# systemctl stop firewalld
    [root@localhost ~]# getenforce 
    Disabled

#### 1.3 重启机器 ####

[root@localhost ~]# reboo7

#### 1.4 设置主机名 ####

[root@localhost ~]# hostnamectl set-hostname openstack
    [root@localhost ~]# cat /etc/hosts
    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.122.15 openstack

#### 1.5 配置DNS ####

[root@openstack ~]# cat /etc/resolv.conf
    nameserver 223.5.5.5

#### 1.6 添加阿里yum源 ####

[root@openstack ~]# rm -rfv * /etc/yum.repos.d/*
    [root@openstack ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

### 2. 系统基本配置 ###

#### 2.1 安装常用工具 ####

[root@openstack ~]# yum install vim bash-completion net-tools

#### 2.2 安装epel ####

[root@openstack ~]# yum install epel-release

#### 2.3 安装依赖 ####

[root@openstack ~]#yum install python-devel libffi-devel gcc openssl-devel libselinux-python -y

#### 2.4 安装pip ####

[root@openstack ~]# yum install python-pip

#### 2.5 配置pip，使用阿里源 ####

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

#### 2.6 更新pip ####

[root@openstack ~]# pip install -U pip

### 3. 安装docker ###

#### 3.1 添加docker源，使用阿里源 ####

[root@openstack ~]#yum install -y yum-utils device-mapper-persistent-data lvm2
    [root@openstack ~]#yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

#### 3.2 安装docker ####

[root@openstack ~]#yum -y install docker-ce-18.03.1.ce-1.el7.centos

#### 3.3 配置docker，使用阿里加速器 ####

[root@openstack ~]# mkdir -p /etc/docker/
    [root@openstack ~]# vim /etc/docker/daemon.json 
    {
      "registry-mirrors": ["https://fl791z1h.mirror.aliyuncs.com"]
    }

#### 3.4 添加kolla.conf ####

[root@openstack ~]# mkdir -p /etc/systemd/system/docker.service.d/
    [root@openstack ~]# vim /etc/systemd/system/docker.service.d/kolla.conf 
    [Service]
    MountFlags=shared

#### 3.5 启动docker ####

[root@openstack ~]# systemctl daemon-reload 
    [root@openstack ~]# systemctl enable docker 
    [root@openstack ~]# systemctl start docker

#### 3.6 登录阿里云仓库 ####

[root@openstack ~]# docker login --username=787166093@qq.com registry.cn-hangzhou.aliyuncs.com
    Password:

密码:kolla@123

### 4. 安装ansible ###

#### 4.1 安装ansible ####

[root@openstack ~]# yum install ansible

#### 4.2 配置ansible ####

[root@openstack ~]# vim /etc/ansible/ansible.cfg 
    [defaults]
    host_key_checking=False
    pipelining=True
    forks=100

### 5. 安装kolla-ansible ###

#### 5.1 安装依赖 ####

kolla分为两个仓库，一个为https://github.com/openstack/kolla , 另一个为https://github.com/openstack/kolla-ansible 在这两个仓库中有requirements.txt文件，需要将其中的依赖安装

[root@openstack ~]# vim 1.txt 
    pbr!=2.1.0,>=2.0.0 # Apache-2.0
    docker>=2.4.2 # Apache-2.0
    Jinja2>=2.8 # BSD License (3 clause)
    GitPython>=1.0.1 # BSD License (3 clause)
    oslo.config>=5.1.0 # Apache-2.0
    oslo.utils>=3.33.0 # Apache-2.0
    setuptools!=24.0.0,!=34.0.0,!=34.0.1,!=34.0.2,!=34.0.3,!=34.1.0,!=34.1.1,!=34.2.0,!=34.3.0,!=34.3.1,!=34.3.2,!=36.2.0,>=21.0 # PSF/ZPL
    netaddr>=0.7.18 # BSD

[root@openstack ~]# vim 2.txt 
    pbr!=2.1.0,>=2.0.0 # Apache-2.0
    docker>=2.4.2 # Apache-2.0
    Jinja2>=2.10 # BSD License (3 clause)
    oslo.config>=5.2.0 # Apache-2.0
    oslo.utils>=3.33.0 # Apache-2.0
    setuptools!=24.0.0,!=34.0.0,!=34.0.1,!=34.0.2,!=34.0.3,!=34.1.0,!=34.1.1,!=34.2.0,!=34.3.0,!=34.3.1,!=34.3.2,!=36.2.0,>=21.0.0 # PSF/ZPL
    PyYAML>=3.12 # MIT
    netaddr>=0.7.18 # BSD
    cryptography>=2.1 # BSD/Apache-2.0
    jmespath>=0.9.3 # MIT

以上两个文件，是我直接从requirements.txt，复制过来的，直接安装即可

root@openstack ~]# pip install -r 1.txt

安装第二个依赖

[root@openstack ~]# pip install -r 2.txt

#### 5.2 安装kolla-ansible ####

[root@openstack ~]# pip install kolla-ansible

在安装kolla-ansible的时候会出现下面的错误

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.

解决方法，在安装kolla-ansible的时候忽略PyYAML

[root@openstack ~]# pip install kolla-ansible --ignore-installed PyYAML

#### 5.3 安装kolla ####

[root@openstack ~]# pip install kolla

### 6. 配置kolla-ansible ###

#### 6.1 创建kolla目录，复制globals.yml，passwords.yml ####

[root@openstack ~]# mkdir -p /etc/kolla/
    [root@openstack ~]# cp /usr/share/kolla-ansible/etc_examples/kolla/* /etc/kolla/

#### 6.2 由于此环境在虚拟机部署，所以virt\_type的类型设置为qemu ####

[root@openstack ~]# mkdir -p /etc/kolla/config/nova/
    [root@openstack ~]# vim /etc/kolla/config/nova/nova-compute.conf 
    [libvirt]
    virt_type = qemu
    cpu_mode = none

#### 6.3 配置globals.yml ####

[root@openstack ~]# cat /etc/kolla/globals.yml  | grep -v ^$| grep -v ^#
    kolla_base_distro: "centos"
    kolla_install_type: "source"
    openstack_release: "train"
    kolla_internal_vip_address: "192.168.122.253"
    docker_registry: "registry.cn-hangzhou.aliyuncs.com"
    docker_namespace: "cloudbl"
    network_interface: "enp0s3"
    neutron_external_interface: "enp0s8"
    neutron_plugin_agent: "linuxbridge"
    enable_neutron_qos: "yes"
    enable_ceph_rgw_keystone: "yes"
    glance_enable_rolling_upgrade: "no"
    ironic_dnsmasq_dhcp_range:
    tempest_image_id:
    tempest_flavor_ref_id:
    tempest_public_network_id:
    tempest_floating_network_name:

以上的配置中，本人使用了自己在阿里上搭建的docker仓库。里面的镜像，是从docker的官网push而来。这个仓库是私有仓库，要是需要使用的话，请联系本作者。  
注：如果此环境所在的网络中还有其它使用Kolla部署的openstack，那么需要修改globals.yml中的

#keepalived_virtual_router_id: "51"

把51改成1到99的之间的整数即可。

### 7 部署openstack ###

#### 7.1 生成openstack密码 ####

[root@openstack ~]# kolla-genpwd

如果执行出现如下错误

[root@openstack ~]# kolla-genpwd
    Traceback (most recent call last):
      File "/usr/bin/kolla-genpwd", line 8, in <module>
        sys.exit(main())
      File "/usr/lib/python2.7/site-packages/kolla_ansible/cmd/genpwd.py", line 133, in main

      File "/usr/lib/python2.7/site-packages/kolla_ansible/cmd/genpwd.py", line 67, in genpwd
        private_key, public_key = generate_RSA()
      File "/usr/lib/python2.7/site-packages/kolla_ansible/cmd/genpwd.py", line 52, in generate_RSA

        self._rsa_cdata
      File "/usr/lib64/python2.7/site-packages/cryptography/hazmat/backends/openssl/backend.py", line 1706, in _public_key_bytes
        return self._openssh_public_key_bytes(key)
      File "/usr/lib64/python2.7/site-packages/cryptography/hazmat/backends/openssl/backend.py", line 1740, in _openssh_public_key_bytes
        serialization._ssh_write_mpint(public_numbers.e) +
    AttributeError: 'module' object has no attribute '_ssh_write_string'

解决方法

[root@openstack ~]# pip uninstall cryptography
    [root@openstack ~]# pip install "cryptography==2.7"

#### 7.2 pull镜像 ####

[root@openstack ~]# kolla-ansible pull
    ...........
    PLAY RECAP ************************************************************************************************************************************************
    localhost                  : ok=40   changed=0    unreachable=0    failed=0    skipped=77   rescued=0    ignored=0

出现以上提示，pull成功。如果在pull中出现问题，可以在评论中留言

#### 7.3 检查Kolla ####

[root@openstack ~]# kolla-ansible prechecks
    PLAY RECAP ************************************************************************************************************************************************
    localhost                  : ok=102  changed=0    unreachable=0    failed=0    skipped=147  rescued=0    ignored=0

出现以上提示，prechecks成功。如果在检查的过程中，有遇到问题，请在评论区留言。

#### 7.4 部署Kolla ####

[root@openstack ~]# kolla-ansible deploy -vvv

等待大概十分钟左右，部署完成

#### 7.5 安装openstack-pythonclient ####

安装openstackclient

[root@openstack ~]# pip install python-openstackclient

在安装的过程中如果出现以下的提示

以上提示说明python环境不支持安装zipp这个库，因为我使用是的centos7.5系统 ，python版本2.7，解决方法，指定zipp版本

[root@openstack ~]# pip install zipp==1.1.0

然后再安装python-openstackclient即可成功

[root@openstack ~]# pip install python-openstackclient

#### 7.7 使用init-runonce脚本创建网络、flavor ####
