云计算基础设施平台iaas（openstack）超级详细搭建（二十）栈stack操作

本篇博客将介绍openstack中的stack的UI操作
首先把所需文件放到http服务上

[root@controller xiandian]# pwd
/etc/xiandian
[root@controller xiandian]# ls
lb-server.yaml  nginx_flat.yaml  nginx.yaml  openrc.sh
[root@controller xiandian]# cp nginx* /var/www/html/
[root@controller xiandian]# cp lb-server.yaml /var/www/html/
[root@controller xiandian]# 

下面分别对上图5个选项进行一一作答

1.admin的密码为000000 也就是openstack的密码

2.yum的URL其实就是我们最初在controller节点搭建的http服务地址。作为一个httpd服务器。可以到我们的yum源中去查看

这里要求的是centos的yum源

[root@compute ~]# vi /etc/yum.repos.d/local.repo 
[centos]
name=centos
baseurl=ftp://192.168.1.11/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=ftp://192.168.1.11/iaas/iaas-repo
gpgcheck=0
enabled=1
~

3.image的name 我们可以使用openstack或者glance基础命令去查看

这里使用的是glance的基础命令

[root@controller html]# glance image-list
+--------------------------------------+-----------+
| ID                                   | Name      |
+--------------------------------------+-----------+
| 35f04fd3-694b-4ac3-9417-f2a61e479ec6 | CentOS7.0 |
| 37fd20a5-9924-417d-9f51-d283251fafca | centos8   |
| 417f7098-6ac9-4d4f-94e7-23e0616d0f7c | mysql-5.6 |
+--------------------------------------+-----------+

4.针对于我们的网络名字，我们可以使用openstack或者是其组件neutron的基础命令去查看

下面我们使用openstack的命令去查看

[root@controller html]# openstack network list
+--------------------------------------+---------+--------------------------------------+
| ID                                   | Name    | Subnets                              |
+--------------------------------------+---------+--------------------------------------+
| 9ccc01f7-9529-400e-a192-e299baf5ba9c | ext_net | 20eb1afc-fa08-4e91-887a-908375794ef7 |
| c2fc035e-bf7e-412c-81c7-4b904fea870b | ins_net | 01655c52-a687-4d29-81df-15b15fa70d88 |
+--------------------------------------+---------+--------------------------------------+
[root@controller html]# 

5 .这里是我们的负载均衡lbaas的ID

我们可以通过openstack的基础命令去查看

[root@controller html]# neutron lb-pool-list
+--------------------------------------+---------------+----------+-------------+----------+----------------+--------+
| id                                   | name          | provider | lb_method   | protocol | admin_state_up | status |
+--------------------------------------+---------------+----------+-------------+----------+----------------+--------+
| a84b45ce-7fcf-4543-b207-2e489fa0722b | resource_pool | haproxy  | ROUND_ROBIN | HTTP     | True           | ACTIVE |
+--------------------------------------+---------------+----------+-------------+----------+----------------+--------+

我们填写完后，之接点击创建就可以了，如下图效果所示

这是栈模板
