手动部署OpenStack Rocky双节点

虚拟机准备

两台虚拟机，每台虚拟机4G内存，各配三个网卡。

OS准备

controller虚拟机

安装CentOS 7.5.1804，内核版本3.10.0-862，机器名controller，3块网卡都是bridge模式，静态IP地址分别设置为：

name ip address memo
ens33 inet 172.18.22.231 Management & API Networking
ens37 inet 10.0.0.1 VM Network
ens38 inet 192.168.1.231 Access to Internet 
[tony@controller ~]$ cat /etc/hostname
controller[tony@controller ~]$ cat /etc/redhat-release

compute虚拟机

3: ens37: inet 10.0.0.2/8 ...
4: ens38: inet 192.168.1.232/24 ...

DNS域名解析

在两台虚拟机上都是用/etc/hosts域名解析机制。

controller虚拟机

[tony@controller ~]$ cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.18.22.231 controller
172.18.22.232 compute

# 确认能ping通
[tony@controller ~]$ ping compute

PING compute (172.18.22.232) 56(84) bytes of data.
64 bytes from compute (172.18.22.232): icmp_seq=1 ttl=64 time=0.346 ms
64 bytes from compute (172.18.22.232): icmp_seq=2 ttl=64 time=0.234 ms
64 bytes from compute (172.18.22.232): icmp_seq=3 ttl=64 time=0.292 ms

compute虚拟机

[tony@compute ~]$ cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.18.22.231 controller
172.18.22.232 compute

# 确认能ping通
[tony@compute ~]$ ping controller

PING controller (172.18.22.231) 56(84) bytes of data.
64 bytes from controller (172.18.22.231): icmp_seq=1 ttl=64 time=0.416 ms

64 bytes from controller (172.18.22.231): icmp_seq=3 ttl=64 time=0.253 ms

时间同步

controller机器使用Internet时间服务更新机器时钟。compute机器则向controller请求时间服务。

controller虚拟机

  • 原始的/etc/chrony.conf文件。
[tony@controller ~]$ cat /etc/chrony.conf | grep -v ^# | grep -v ^$

  • 修改后的/etc/chrony.conf文件
[tony@controller ~]$ cat /etc/chrony.conf | grep -v ^# | grep -v ^$

  • 重启NTP服务
[tony@controller ~]$ sudo systemctl enable chronyd.service
[tony@controller ~]$ sudo systemctl restart chronyd.service
  • 检查chronyd的源
[tony@controller ~]$ sudo chronyc sources

YUM 仓库源

在controller机器与compute机器上安装需要的包。两台机器上安装的包是一样的，命令参考如下：

yum install centos-release-openstack-rocky -y
yum upgrade -y
yum install python-openstackclient -y
yum install openstack-selinux -y

controller虚拟机

[tony@controller ~]$ sudo yum install -y centos-release-openstack-rocky# 这条命令会升级Centos，所以执行完毕后，重启一下机器
[tony@controller ~]$ sudo yum update -y
[tony@controller ~]$ sudo reboot# 升级完后内核版本从3.10.0-862变成了3.10.0-957
[tony@controller ~]$ uname -a
Linux controller 3.10.0-957.10.1.el7.x86_64 #1 SMP Mon Mar 18 15:06:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux# 继续安装需要用的包
[tony@controller ~]$ sudo yum install -y python-openstackclient
[tony@controller ~]$ sudo yum install -y openstack-selinux

compute虚拟机

[tony@compute ~]$ sudo yum install -y centos-release-openstack-rocky# 这条命令会升级Centos，所以执行完毕后，重启一下机器
[tony@compute ~]$ sudo yum update -y
[tony@compute ~]$ sudo yum reboot# 升级完后内核版本从3.10.0-862变成了3.10.0-957
[tony@compute ~]$ uname -a
Linux compute 3.10.0-957.10.1.el7.x86_64 #1 SMP Mon Mar 18 15:06:45 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux# 继续安装需要用的包
[tony@compute ~]$ sudo yum install -y python-openstackclient
[tony@compute ~]$ sudo yum install -y openstack-selinux

MySQL数据库 (controller-only)

只需要在controller机器上安装MySQL数据库。无需在compute机器上安装。

controller虚拟机

  • 安装数据库
[tony@controller ~]$ sudo yum install -y mariadb mariadb-server python2-PyMySQL
  • 创建配置文件
[tony@controller ~]$ sudo vim  /etc/my.cnf.d/openstack.cnf

插入如下配置

[mysqld]
bind-address = 172.18.22.231
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

  • 启动mariadb服务
# 检查mariadb服务，此时没有启动
[tony@controller ~]$ sudo systemctl status mariadb.service

  • 初始化MySQL数据库密码
[tony@controller ~]$ mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
 
In order to log into MariaDB to secure it, we’ll need the current
password for the root user. If you’ve just installed MariaDB, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here. <just press Enter>
 
Enter current password for root (enter for none):
OK, successfully used password, moving on…
 
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
 
Set root password? [Y/n] Y
New password: 输入密码
Re-enter new password: 输入密码
Password updated successfully!
Reloading privilege tables…
… Success!
 
 
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
 
Remove anonymous users? [Y/n] Y
… Success!
 
Normally, root should only be allowed to connect from ‘localhost’. This
ensures that someone cannot guess at the root password from the network.
 
Disallow root login remotely? [Y/n] Y
… Success!
 
By default, MariaDB comes with a database named ‘test’ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
 
Remove test database and access to it? [Y/n] Y

  • Dropping test database…
    … Success!
  • Removing privileges on test database…
    … Success!
     
    Reloading the privilege tables will ensure that all changes made so far
    will take effect immediately.
     
    Reload privilege tables now? [Y/n] Y
    … Success!
     
    Cleaning up…
     
    All done! If you’ve completed all of the above steps, your MariaDB
    installation should now be secure.
     
    Thanks for using MariaDB!
