openstack平台部署(二)

根据openstack(前期准备)和openstack(一)两个章节的配置,完成了部署openstack所需的基础配置。

一、OpenStack搭建任务

在控制节点和计算节点上分别安装iaas-xiandian软件包,根据表2配置两个节点脚本文件中的基本变量(配置脚本文件为/etc/xiandian/openrc.sh)。

1.1 安装iaas-xiandian服务,并修改xiandian服务的配置文件

1.1.1 安装iaas-xiandian服务(在两节点执行);

yum -y install iaas-xiandian
image-20220713000051130image-20220713000051130

1.1.2 修改xiandian服务的配置文件

vi /etc/xiandian/openrc.sh
 
# 进入配置文件后需要在命令行模式下敲
:%s/^#//g # 一行中只带有一个#注释的,作用去除#注释
:%s/PASS=/PASS=000000/g # 将PASS=全部替换成PASS=000000,这样省的我们自己手动敲很多代码了

需要修改的地方已在后面增加注释(有的地方还需输入六个零上面会有 example: 提示)

通过scp方法将修改过的xiandian配置文件传输到compute节点

scp /etc/xiandian/openrc.sh compute:/etc/xiandian/openrc.sh

在compute节点中将xiandian配置文件修改第69行的IP地址,改成对应节点的IP地址(在compute节点只需修改这一行)

image-20220713000448821image-20220713000448821

修改完成后保存退出。

二.通过脚本安装服务

2.1-2.3的基础配置操作命令已经编写成shell脚本,通过脚本进行一键安装。如下:

执行脚本iaas-pre-host.sh进行安装

#Controller节点
[root@controller ~]# iaas-pre-host.sh

#Compute节点
[root@compute ~]# iaas-pre-host.sh

安装完成后同时重启

#Controller节点
[root@controller ~]# reboot

#Compute节点
[root@compute ~]# reboot

2.1 安装Openstack包

#Controller节点
[root@controller ~]# yum -y install openstack-utils openstack-selinux python-openstackclient
[root@controller ~]# yum upgrade

#Compute节点
[root@compute ~]# yum -y install openstack-utils openstack-selinux python-openstackclient
[root@compute ~]# yum upgrade

2.2 配置域名解析

2.2.1 修改/etc/hosts添加一下内容。

#Controller节点
172.129.7.10 controller
172.129.7.20 compute

#Compute节点
172.129.7.10 controller
172.129.7.20 compute

2.3 安装chrony服务

2.3.1 安装chrony服务;

#Controller节点
[root@controller ~]# yum install -y chrony

#Compute节点
[root@compute ~]# yum install -y chrony

2.3.2 配置controller节点

image-20220713164240811image-20220713164240811

#Controller节点
[root@controller ~]# vi /etc/chrony.conf #编辑/etc/chrony.conf文件
#添加以下内容(删除默认sever规则,默认sever规则如上图)
server controller iburst
allow 192.168.100.0/24
#启动ntp服务器
[root@controller ~]# systemctl restart chronyd
[root@controller ~]# systemctl enable chronyd

#Compute节点
[root@compute ~]# vi /etc/chrony.conf #编辑/etc/chrony.conf文件
#添加以下内容(删除默认sever规则,默认sever规则如上图)
server controller iburst
#启动ntp服务器
[root@compute ~]# systemctl restart chronyd
[root@compute ~]# systemctl enable chronyd

三、通过脚本安装openstack相关服务

依次运行相关脚本,脚本运行时间看虚拟机配置。

3.1 数据库安装

在controller节点上使用iaas-install-mysql.sh 脚本安装Mariadb、Memcached、etcd服务。

#Controller节点
[root@controller ~]# iaas-install-mysql.sh

3.2 Keystone服务安装

在controller节点上使用iaas-install-keystone.sh 脚本安装Keystone服务。

#Controller节点
[root@controller ~]# iaas-install-keystone.sh 

3.3 Glance安装

在controller节点上使用iaas-install-glance.sh脚本安装glance 服务。

#Controller节点
[root@controller ~]# iaas-install-glance.sh

3.4 Nova安装

在controller节点和compute节点上分别使用iaas-install-nova -controller.sh脚本、iaas-install-nova-compute.sh脚本安装Nova 服务。

#Controller节点
[root@controller ~]# iaas-install-nova -controller.sh

#Compute节点
[root@compute ~]# iaas-install-nova-compute.sh

3.5 Neutron安装

在controller节点和compute节点上分别修改iaas-install-neutron-controller.sh脚本、iaas-install-neutron-compute.sh脚本分别安装 Neutron 服务。

#Controller节点
[root@controller ~]# iaas-install-neutron-controller.sh

#Compute节点
[root@compute ~]# iaas-install-neutron-compute.sh

3.6 Doshboard安装

在controller节点上使用iaas-install-dashboad.sh脚本安装dashboad服务。

#Controller节点
[root@controller ~]# iaas-install-dashboad.sh

3. 7 Cinder安装

在控制节点和计算节点上分别使用iaas-install-cinder-controller.sh脚本和iaas-install-cinder-compute.sh安装cinder服务。

#Controller节点
[root@controller ~]# iaas-install-cinder-controller.sh

#Compute节点
[root@compute ~]# iaas-install-cinder-compute.sh
