1. 使用packstack部署openstack

redhat开源项目 RDO， 利用puppet 管理openstack

使用RDO项目中的工具packstack 安装openstack：

一种是 allinone 方式 ：

 把openstack的各个组件全部安装到一台机器上去，安装的时候很多都是不可以定制，allinone只适合做测试环境，体验一下openstack

同时，会预下载一个镜像cirros及配置模拟环境，从互联网上下载，其下载地址是国外网址，所以最好禁止这部分，后文有说这一点provision_demo

一种是应答文件的方式：

生成一个应答文件，然后根据需要对这个应答文件进行修改. 下文是通过应答文件来部署的。

 

首先建立RHEL 7.2的环境，然后在RHEL7.2上安装openstack：

新建的RHEL 7.2环境，配置如下：

内存：需要大于5G

处理器：给2个即可

硬盘：100G

网络：NAT----具体IP地址段，查看下面

 

RHEL7.2的分区管理如下：

挂载sda1 挂到  根目录       /  采用标准分区

挂载sda2 挂到    swap            采用标准分区

 

·        RHEL7.2启动配置完毕后，由于系统默认的interface是 enoXXXXX格式，此处我们改成eth0的格式，修改方式如下：

 

 

vim /etc/default/grub

修改如下内容：

GRUB_CMDLINE_LINUX="rhgbquiet net.ifnames=0 biosdevname=0"

grub2-mkconfig-o   /boot/grub2/grub.cfg

reboot

·        重启之后，系统起来后即变成了eth0

关闭selinux：

vim /etc/selinux/config

修改SELINUX=permissive

setenforce 0

getenforce

 

关闭防火墙，放行所有流量：

firewall-cmd--set-default-zone=trusted

 

修改本机的hostname如下： 此部分可以在RHEL7.2 创建时候设置，如果未设置可以用hostnamectl --set-hostname 设置。

[root@osp1 ~]# hostname

osp1.example.com

 

修改本地地址解析hosts：

vim /etc/hosts

 

上传openstack安装包：

 

下面创建repos：

第一： RHEL7.2 repos：

mount cdrom 光盘内容到   /iso下面， 如果没有/iso， mkdir  /iso

（此处必须保证光盘connected）

 

创建新的RHEL7.2 repo：

 

清除原有的yum信息：

 

第二：制作openstack repos：

此处安装vsftpd 软件，（原因：我们会将openstack 的repo 创建在/var/ftp下面，让本机启用ftp业务，之后新增加的compute即可不用创建自己的repos，采用ftp 到本机即可下载安装软件包）

 

启用vsftpd服务并开启下次开机启动：

 

mount其OPENSTACK 包到 /mnt下：

cd /var/ftp 目录下，复制所有的包到osp/下，createrepo 定义yum 源：

 

编辑 yum 配置文件如下：

 

安装packstack 软件包：

 

 

P.S.:

allinone 安装命令如下：

 

此处采用应答文件的方式安装：

 

 

 

 

修改provision_demo为n（no）

然后使用sed 对所有的相关密码进行修改：

# sed -i.bak -r 's/(.+_PW)=[0-9a-z]+/\1=redhat/'aa.txt

 

开始安装：

 

安装完成：

 

如图所示：

有些服务依赖于NTP，我们此处没有NTP SERVER。

系统启用了NetworkManager， 为防止冲突，关闭它。

如何介入openstack的dashboard

登录dashboard的账户信息在某个文件里。

Additional information:

 * Time synchronization installation wasskipped. Please note that unsynchronized time on server instances might beproblem for some OpenStack co

mponents.

* Warning:NetworkManager is active on 192.168.179.137. OpenStack networking currentlydoes not work on systems that have the Network Manager se

rviceenabled.

 * File/root/keystonerc_admin has been created on OpenStack client host192.168.179.137. To use the command line tools you need to source the fi

le.

* Toaccess the OpenStack Dashboard browse to http://192.168.179.137/dashboard .

Please,find your login credentials stored in the keystonerc_admin in your homedirectory.

 * Theinstallation log file is available at:/var/tmp/packstack/20171217-155854-Z_RpoS/openstack-setup.log

 * Thegenerated manifests are available at:/var/tmp/packstack/20171217-155854-Z_RpoS/manifests

 

关闭NetworkManager：

登录dashboard的账户信息如下： admin/redhat

 

 

 

Verifyinstallation.

Start a session to the newly installed system,source the keystonerc_admin

如何新增加一个计算节点：

[首先重新安装一个新的RHEL7.2虚拟机，按照上面的步骤新建一个计算节点]

之后做如下配置：osp2 修改selinux，firewall，hostname ，hosts， 同时修改osp1的hosts内容

 

osp2 hosts配置：

osp1 hosts 增加新加的osp2 计算节点：

创建yum源：

 

 

修改enoXXXX 为eth0：

mv ifcfg-enoXXXXX ifcfg-eth0

 

 

安装packstack 软件包：

disable NetworkManager服务：

 

 

在osp1 的应答文件中增加新的计算节点ip即可：

 

 

 

重新运行一次packstack 应答文件：

 

直到最终显示如下的结果：

 

 

最终会在dashboard中看到这个新增加的计算节点：如图所示
