CentOS 8搭建 OpenStack(开源U版) 的方法和步骤

OpenStack是一个开源的云计算管理平台项目，是一系列软件开源项目的组合。由NASA(美国国家航空航天局)和Rackspace合作研发并发起，以Apache许可证（Apache软件基金会发布的一个自由软件许可证）授权。 OpenStack为私有云和公有云提供可扩展的弹性的云计算服务。项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台--来自百度百科.（<https://baike.baidu.com/item/OpenStack/342467>）。

一、前期准备

1、准备3台虚拟机（1个控制节点、2个计算节点）

- 首先安装VMware WorkStations（最新版），
- 新增虚拟机，
- 镜像使用CentOS-Stream-8-x86_64-latest-dvd1.iso（下载地址<https://mirrors.tuna.tsinghua.edu.cn/centos/8-stream/isos/x86_64/CentOS-Stream-8-x86_64-latest-dvd1.iso>）
- 安装完成后克隆两台虚拟机(计算节点)。

2、虚拟机的性能要求：

-  内存大于等于8G
-  硬盘200G
-  CPU至少2核，开启vt-x
-  网卡2块，一张网卡用来连接互联网，另外一张网卡用来内部互联。

3、虚拟机操作系统分区结构要求。

- /50G(根分区)
- /boot 500MB(boot-开机引导及内核程序)
- /home
- swap 4G(内存交换分区)

Kdump（kernel dump，内核备份），内存小于2G，则Kdump就不会生效。所以想生效，内存必须大于2G，当安装界面的Kdump不管勾不勾选，都会占用160M内存。
如果勾选了，系统每次启动时，内核会被读到160M内存中，如果系统崩溃，就可以还原内核。如果不勾选，当内核崩溃时，就无法恢复。

二、系统初始化配置

2.1 主机名配置

[root@localhost \~]\# hostnamectl set-hostname controller
[root@localhost \~]\# hostnamectl set-hostname computer1
[root@localhost \~]\# hostnamectl set-hostname computer2

2.2 网络配置

控制节点：

[root@controller \~]\# vim /etc/sysconfig/network-scripts/ifcfg-ens160 注意：此处的“ens160”的编号160要根据自己的网卡编号修改 手动修改以下内容（全部dd删除后，复制以下内容进行粘贴）
TYPE=Ethernet
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.142
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=114.114.114.114

计算节点1：

[root@computer1 \~]\# vim /etc/sysconfig/network-scripts/ifcfg-ens160 注意：此处的“ens160”的编号160要根据自己的网卡编号修改 手动修改以下内容（全部dd删除后，复制以下内容进行粘贴）
TYPE=Ethernet
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.143
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=114.114.114.114

计算节点2：

[root@computer \~]\# vim /etc/sysconfig/network-scripts/ifcfg-ens160 注意：此处的“ens160”的编号160要根据自己的网卡编号修改 手动修改以下内容（全部dd删除后，复制以下内容进行粘贴）
TYPE=Ethernet
NAME=ens160
DEVICE=ens160
ONBOOT=yes
IPADDR=192.168.100.144
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=114.114.114.114

[root@controller ~]# nmcli connection reload #重新加载配置文件
[root@controller ~]# nmcli connection up ens160 #重启网卡
同理在计算节点也使用相同命令，确保配置生效。

2.3 添加hosts文件主机记录

[root@controller \~]\# vim /etc/hosts 手动添加以下内容
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.142 controller
192.168.100.143 computer1
192.168.100.144 computer2
将以上控制节点的配置拷贝到两个计算节点对应的文件夹里。
[root@controller \~]\# scp /etc/hosts root@computer1:/etc
The authenticity of host 'computer1 (192.168.100.143)' can't be established.
ECDSA key fingerprint is SHA256:iRpcQnjcRiW1KLcgFGFqmiP3Yx4Xfa0cGu02seIhf8E.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'computer1,192.168.100.143' (ECDSA) to the list of known hosts.
root@computer1's password:**请输入root密码即可**
hosts 100% 240 49.0KB/s 00:00
[root@controller \~]\#
[root@controller \~]\# scp /etc/hosts root@computer2:/etc
The authenticity of host 'computer2 (192.168.100.144)' can't be established.
ECDSA key fingerprint is SHA256:iRpcQnjcRiW1KLcgFGFqmiP3Yx4Xfa0cGu02seIhf8E.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'computer2,192.168.100.144' (ECDSA) to the list of known hosts.
root@computer2's password: **请输入root密码即可**
hosts 100% 240 53.7KB/s 00:00
[root@controller \~]\#

2.4 关闭所有节点防火墙和SeLinux

永久关闭防火墙，防止开机自启。

[root@controller \~]\# systemctl disable firewalld.service --now
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@computer1 \~]\# systemctl disable firewalld.service --now
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@computer2 \~]\# systemctl disable firewalld.service --now
Removed /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

永久关闭SeLinux，防止开机自启。

[root@controller \~]\# vim /etc/selinux/config
\# This file controls the state of SELinux on the system.
\# SELINUX= can take one of these three values:
\# enforcing - SELinux security policy is enforced.
\# permissive - SELinux prints warnings instead of enforcing.
\# disabled - No SELinux policy is loaded.
SELINUX=enforcing**（将enforcing改为disabled）**
\# SELINUXTYPE= can take one of these three values:
\# targeted - Targeted processes are protected,
\# minimum - Modification of targeted policy. Only selected processes are protected.
\# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@controller \~]\# setenforce 0(这个只是临时关闭SeLinux)
另外两个计算节点也是相同配置。

++++++++++++++++++关闭3台主机并拍摄快照+++++++++++++++++++++

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

2.9. 在controller控制节点上启动数据库

[root@controller \~]\# systemctl enable mariadb.service --now
[root@controller \~]\# mysql_secure_installation（安全加固）
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.
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
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:
Re-enter new password:
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]
... 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]
... 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]
\- 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]
... 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!
[root@controller \~]\# systemctl restart mariadb.service

TIME_ZONE = "Asia/Shanghai" \#\#\#原内容为：TIME_ZONE = "UTC"
原内容OPENSTACK_KEYSTONE_URL = "http://%s/identity/v3" % OPENSTACK_HOST更改为：
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

增加的内容：
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
CACHES = {
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': 'controller:11211',
}
}
