手动部署 OpenStack Rocky 双节点

关于机器名变更

由于实验室网络冲突，机器变更如下。

原机器名	新机器名	/etc/hosts文件
controller	tony-controller	172.18.22.231 controller
compute	tony-compute1	172.18.22.232 compute1

controller / tony-controller网络配置

[tony@tony-controller ~]$ sudo ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP inet 172.18.22.231/24 brd 172.18.22.255 scope global noprefixroute enp0s3

compute1 / tony-compte1网络配置

Horizon (controller-only)

安装软件包

[tony@tony-controller ~]$ sudo yum install -y openstack-dashboard

dashboard.conf文件

在原配置文件里，加入如下标红的一行即可。

[tony@tony-controller ~]$ sudo cat /etc/httpd/conf.d/openstack-dashboard.conf

大功告成

看起来一切正常，尝试在浏览器中输入http://tony-controller/dashboard，进入openstack登录界面。

登录Openstack之后的主窗口界面。

自此，手动在双机上安装OpenStack Rocky的实录工作正式完成。
