简单几步单节点部署openstack私有云

这几天闲来无事，就随手部署了个openstack私有云，总的来说还是蛮简单的，只是耗时比较长，我8G内存的耗费了近1个小时

openstack是一个开源的云计算平台，它不是一个单一的项目，而是由多个相关项目组成，包含nova,swift,glance,keystone,horizon等，这些项目各实现不同功能，例如弹性计算服务、对象存储服务、虚拟机磁盘镜像服务、安全统一认证服务等，目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。

1.把防火墙这些关掉，避免冲突

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disabled firewalld
Unknown operation 'disabled'.
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# setenforce 0

2.下载安装openstack软件仓库（我这里用stein版）和部署工具packstack

[root@localhost ~]# yum install -y centos-release-openstack-stein
已加载插件：fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: ftp.sjtu.edu.cn
 * extras: ftp.sjtu.edu.cn
 * updates: ftp.sjtu.edu.cn
 <以下部分省略>
 [root@localhost ~]# yum-config-manager --enable openstack-stein
已加载插件：fastestmirror, langpacks
[root@localhost ~]# yum update
已加载插件：fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: ftp.sjtu.edu.cn

 * centos-qemu-ev: ftp.sjtu.edu.cn
 * extras: ftp.sjtu.edu.cn
 * updates: ftp.sjtu.edu.cn
<以下部分省略>
[root@localhost ~]# yum install -y https://rdoproject.org/repos/rdo-release.rpm
已加载插件：fastestmirror, langpacks
rdo-release.rpm                                          | 6.7 kB     00:00     
正在检查 /var/tmp/yum-root-35mOa0/rdo-release.rpm: rdo-release-train-1.noarch
/var/tmp/yum-root-35mOa0/rdo-release.rpm 将被安装
正在解决依赖关系
<以下部分省略>
[root@localhost ~]# yum install -y openstack-packstack

<以下部分省略>

3.执行部署命令
（等待时间较长，我等了近一小时）

[root@localhost ~]# packstack --allinone

 **** 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-20210719-192617.txt
 * Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
 * Warning: NetworkManager is active on 192.168.xx.xxx. OpenStack networking currently does not work on systems that have the Network Manager service enabled.
 * File /root/keystonerc_admin has been created on OpenStack client host 192.168.xx.xxx. To use the command line tools you need to source the file.
 * To access the OpenStack Dashboard browse to http://192.168.xx.xxx/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
 * Because of the kernel update the host 192.168.xx.xxx requires reboot.

4.部署成功后，接下来获取自己的账号密码

[root@localhost ~]# cat ~/keystonerc_admin

5.在浏览器中输入http://192.168.xx.xxx/dashboard 
(ip为自己本机的ip地址)

到这里就部署完成啦！
