使用packstack快速部署OpenStack

本文记录了基于CentOS操作系统使用packstack快速部署openstack。

资源列表

操作系统	配置	磁盘	IP	数量
CentOS7.9	4C8G	50G	192.168.207.155	1

基础环境

服务器开启虚拟化，我这里使用的是VMware虚拟机，所以勾选虚拟化Intel VT-x/EPT或AMD-V/RVI(V)
关闭防火墙

bash 复制代码

systemctl stop firewalld
systemctl disable firewalld

关闭内核安全机制

bash 复制代码

sed -i "s/.*SELINUX=.*/SELINUX=disabled/g" /etc/selinux/config

修改IP为静态IP，若已经是静态IP可以跳过

bash 复制代码

nmcli con mod ens33 ipv4.method static ipv4.address 192.168.207.155/24 ipv4.gateway 192.168.207.2 ipv4.dns 192.168.207.2

修改主机名

bash 复制代码

# 注意这里修改的主机名不能有下划线
hostnamectl set-hostname openstack

关闭NetworkManager

bash 复制代码

systemctl stop NetworkManager
systemctl disable NetworkManager

添加hosts

bash 复制代码

echo "192.168.207.155 openstack" >> /etc/hosts

重启服务器

bash 复制代码

reboot

安装packstack

bash 复制代码

# 更新软件包
yum -y update
# 安装train版本包
yum -y install centos-release-openstack-train
# 安装packstack
yum -y install openstack-packstack

安装OpenStack

bash 复制代码

# 该过程耗时较长，约30分钟左右
packstack --allinone


# 出现以下信息表示成功
 **** Installation completed successfully ******

Additional information:

- Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS or FWaaS services. Geneve will be used as the encapsulation method for tenant networks
- A new answerfile was created in: /root/packstack-answers-20200221-143136.txt
- Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
- File /root/keystonerc_admin has been created on OpenStack client host 192.168.207.131. To use the command line tools you need to source the file.
- To access the OpenStack Dashboard browse to http://192.168.207.131/dashboard .
  Please, find your login credentials stored in the keystonerc_admin in your home directory.
- The installation log file is available at: /var/tmp/packstack/20200221-143136-tbr4ug/openstack-setup.log
- The generated manifests are available at: /var/tmp/packstack/20200221-143136-tbr4ug/manifests

# 查看keystonerc_admin文件获取账号密码(通常在用户的家目录)
# 以此为例用户就是admin，密码则是4dc0395edf0a4fe7
[root@openstack ~]# cat /root/keystonerc_admin 
unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin
    export OS_PASSWORD='4dc0395edf0a4fe7'
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://192.168.247.3:5000/v3
    export PS1='[\u@\h \W(keystone_admin)]\$ '
    
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

如果有问题的可以使用该命令指定应答文件再次执行

bash 复制代码

packstack --answer-file=[应答文件]

在安装完openstack以后会有一个br-ex网卡这个是临时的需要写个配置文件

bash 复制代码

[root@openstack ]# ifconfig br-ex
br-ex: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.24.4.1  netmask 255.255.255.0  broadcast 0.0.0.0
        inet6 fe80::5cde:dcff:fe75:fb43  prefixlen 64  scopeid 0x20<link>
