(1).Kolla概述
Kolla是OpenStack下用于自动化部署的一个项目，它基于docker和ansible来实现，其中docker主要负责镜像制作和容器管理，ansible主要负责环境的部署和管理。
Kolla实际上分为两部分：Kolla部分提供了生产环境级别的镜像，涵盖了OpenStack用到的各个服务；Kolla-ansible部分提供了自动化的部署。最开始这两部分是在一个项目中的（即Kolla），OpenStack从O开头的版本开始被独立开来，这才有了用于构建所有服务镜像的Kolla项目，以及用于执行自动化部署的Kolla-ansible。
(2).Linux系统硬件配置
需要一台高配VMware虚拟机，内存12G，硬盘200G（swap分区4G，boot分区200M，剩下全给根目录），CPU开启虚拟化支持，双网卡桥接模式。
(3).准备工作
如果是最小化安装，那么按<Tab>键是不会自动补全的，所以此时需要安装bash-completion。另外还需要安装vim和net-tools工具
[root@Openstack240 ~]# yum -y install bash-completion vim net-tools
关闭SELinux和firewalld
[root@Openstack240 ~]# vi /etc/selinux/config
SELINUX=disabled
[root@Openstack240 ~]# setenforce 0
[root@Openstack240 ~]# getenforce
Permissive
[root@Openstack240 ~]# systemctl disable firewalld && systemctl stop firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@Openstack240 ~]# systemctl status firewalld

配置/etc/hosts
[root@Openstack240 ~]# vim /etc/hosts 192.168.128.240 OpenStack
下载epel源
[root@Openstack240 ~]# yum -y install epel-release
配置网卡信息
| IP地址 | 网络类型 | 网卡 | 在OpenStack网络中的作用 |
| 192.168.128.240 | bridge（桥接） | ens32 |
OpenStack内部管理网络（management network），Horizon web界面访问就是通过该网卡 |
| 无（不能配置IP地址） | bridge（桥接） | ens33 | 外部网络（external network），让neutron（OpenStack中的网络组件）的br-ex绑定使用，OpenStack中的虚拟机是通过该网卡与外网通信 |
[root@Openstack240 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32 //修改以下几行，如果不存在则添加 BOOTPROTO=none //将dhcp改为none，使自动获取改为静态获取 ONBOOT=yes //启动用该网卡 IPADDR=192.168.128.240 //设置IPv4地址 NETWORK=255.255.255.0 //设置子网掩码 GATEWAY=192.168.128.254 //设置默认网关 DNS1=61.177.7.1 //设置DNS [root@Openstack240 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33 //修改以下几行，并将其移动到文件开头，如果不存在则添加。 TYPE=Ethernet NAME=ens33 DEVICE=ens33 //如果是开启虚拟机后添加网卡，需要手动编辑以上三行 BOOTPROTO=none //将dhcp改为none，使自动获取改为静态获取 ONBOOT=yes //启用该网卡
安装基础包
//安装基础包 [root@Openstack240 ~]# yum -y install python-devel libffi-devel gcc openssl-devel git python-pip //配置pip镜像源，方便快速下载python库（默认从国外下载） [root@Openstack240 ~]# mkdir .pip [root@Openstack240 ~]# tee .pip/pip.conf << EOF //不知道为什么cat失败，所以用了tee > [global] > index-url=http://mirrors.aliyun.com/pypi/simple/ > [install] > trusted-host=mirrors.aliyun.com > EOF //升级pip [root@Openstack240 ~]# pip install -U pip
(4).安装kolla-ansible
1）使用pip安装ansible，注意不要使用yum安装，否则会与kolla中的YAML包冲突
[root@Openstack240 ~]# pip install ansible
2）使用pip安装kolla-ansible
[root@Openstack240 ~]# pip install kolla-ansible
如果出现如下错误
//已经存在PyYAML3.10导致不能安装PyYAML Found existing installation: PyYAML 3.10 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. //出现如上错误，请执行以下步骤 [root@Openstack240 ~]# pip install PyYAML --ignore-installed PyYAML //忽略已经安装的PyYAML，安装PyYAML [root@Openstack240 ~]# pip install kolla-ansible //重新安装kolla-ansible
3）复制kolla-ansible的相关配置文件
[root@Openstack240 ~]# cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/ [root@Openstack240 ~]# ls /etc/kolla/ globals.yml passwords.yml [root@Openstack240 ~]# cp /usr/share/kolla-ansible/ansible/inventory/* /etc/kolla/ [root@Openstack240 ~]# ls /etc/kolla/ all-in-one globals.yml multinode passwords.yml
文件说明：all-in-one是安装单节点OpenStack的ansible自动安装配置文件；multinode是安装多节点OpenStack的ansible自动安装配置文件；globals.yml是OpenStack部署的自定义配置文件；passwords.yml是OpenStack中各个服务的密码文件。
(5).编辑kolla-ansible的配置文件，用于自定义安装OpenStack
生成OpenStack各个服务的密码文件，并修改Web页面登录密码
[root@Openstack240 ~]# kolla-genpwd [root@Openstack240 ~]# vim /etc/kolla/passwords.yml //修改第165行，这是登录Dashboard（web界面控制台）的密码。正常情况下也不能太简单，可以截取一段自动生成的密码 keystone_admin_password: 123456
编辑/etc/kolla/global.yml自定义OpenStack中的部署事项
[root@Openstack240 ~]# vim /etc/kolla/globals.yml //第14行和第15行，选择下载的基础镜像，5选1 # Valid options are [‘centos‘, ‘debian‘, ‘oraclelinux‘, ‘rhel‘, ‘ubuntu‘] kolla_base_distro: "centos" //第17行和第18行，选择的安装方法，2选1。binary二进制安装，source源码安装 # Valid options are [ binary, source ] kolla_install_type: "source" //第20行和第21行，选择OpenStack的版本标签，详细请看：https://releases.openstack.org/ # Valid option is Docker repository tag openstack_release: "stein" //注意版本必须小写，后期下载的OpenStack相关的docker镜像标签也为stein。我是train版本失败，才换成stein //第23行和第24行，存放配置文件的位置 # Location of configuration overrides #node_custom_config: "/etc/kolla/config" //默认存放地址 //第31行，OpenStack内部管理网络地址，通过该IP访问OpenStack Web页面进行管理。如果启用了高可用，需要设置为VIP（漂移IP） kolla_internal_vip_address: "192.168.128.240" //第87行，OpenStack内部管理网络地址的网卡接口 network_interface: "ens32" //第105行，OpenStack外部（或公共）网络的网卡接口，可以是vlan模式或flat模式。 //此网卡应该在没有IP地址的情况下处于活动，如果不是，那么OpenStack云平台中的云主机实例将无法访问外部网络。（存在IP时br-ex桥接就不成功） neutron_external_interface: "ens33" //第190行，关闭高可用 enable_haproxy: "no" //第213行，关闭cinder（块存储） #enable_cinder: "no" //第443行和第444行,指定nova-compute守护进程使用的虚拟化技术。（kvm好像有点问题，大家可以试试，看看你们能不能过nova下载）
//nova-compute是一个非常重要的守护进程，负责创建和终止虚拟机实例，即管理虚拟机实例的生命周期 # Valid options are [ qemu, kvm, vmware, xenapi ] nova_compute_virt_type: "qemu"
(6).基于kolla-ansible安装OpenStack私有云
生成ssh key，并给自己授权
[root@Openstack240 ~]# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory ‘/root/.ssh‘. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub.

配置单节点清单文件
[root@Openstack240 ~]# vim /etc/kolla/all-in-one //修改第3行到第19行，将localhost ansible_connection=local改为OpenStack //可以使用替换命令":1,$s/localhost ansible_connection=local/OpenStack/" [control] OpenStack [network] OpenStack [compute] OpenStack [storage] OpenStack [monitoring] OpenStack [deployment] OpenStack
开始部署OpenStack。注意：我在使用阿里云的epel源时，在安装bootstrap-server时会卡在TASK [baremetal : Install yum packages]这一步。而系统安装的epel源只等待了5分钟左右。
//安装bootstrap-servers部署OpenStack所需的依赖包。该包由kolla-ansible提供，包含docker。
[root@Openstack240 ~]# kolla-ansible -i /etc/kolla/all-in-one bootstrap-servers
//对当前主机进行预部署（检测），直接看最后的统计即可。如果检测报错，可以查看前面的TASK:[precheck ...]部分，可以快速定位到错误
[root@Openstack240 ~]# kolla-ansible -i /etc/kolla/all-in-one prechecks

报错1：拉取镜像失败。
首先重复尝试几次拉取镜像操作。如果还是失败，先检测/etc/kolla/globals.yml中第21行版本号是否正确。在版本号正确的情况下再次拉取镜像还是报错，那么向前退一个版本尝试拉取镜像。（我就是train版本无法使用，退回到stein版本）
报错2：部署失败（我没遇到，有待测试）
如果部署时报以下错误：

可以尝试重新部署，会自动解决该问题。
