openstack部署
1.基础环境准备
1.1.主机名修改
[root@slave2 ~]# hostnamectl set-hostname controller
[root@slave2 ~]# bash
[root@controller ~]#
# 修改后hostname文件内容对应修改
[root@controller ~]# cat /etc/hostname
controller
1.2.yum源配置
# 切换到yum目录
[root@controller ~]# cd /etc/yum.repos.d/
# 创建备份目录
[root@controller yum.repos.d]# mkdir repo.bak
[root@controller yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo repo.bak
# 把原来的yum文件移到到备份目录
[root@controller yum.repos.d]# mv *.repo repo.bak/
# 下载阿里的yum源
[root@controller yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

# 清理yum
[root@controller yum.repos.d]# yum clean all

Cleaning repos: base extras updates
Cleaning up everything
Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

1.3本地域名的解析
直接通过主机名访问主机，需要将主机名和IP地址进行绑定，绑定工作可以通过本地域名解析来实现。
Linux中的 /etc/hosts 文件可以将一些常用的域名和对应的IP建立对应关系。
# 每一行都表示一个域名到Ip地址的映射关系
# 127.0.0.1表示IPv4的本地IP地址
# ::1表示IPv6的本地IP地址
[root@controller yum.repos.d]# vi /etc/hosts
[root@controller yum.repos.d]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.100.131 controller

二.Openstack基础支持服务
Openstack平台需要借助多种第三方提供的基础服务才能正常运行，数据库、消息队列、时间同步、缓存服务等。
2.1Chrony时间同步服务
同一个系统内的计算机时间必须保持一致才能保证系统工作正常。
Chrony软件是一款开源的自由软件，包括两个核心组件：chronyd（后台守护程序）和chronyc（命令行用户管理工具）。
2.1.1时间同步服务配置
# 安装chrony

3.4初始化mariadb数据库
[root@controller my.cnf.d]# 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.
Enter current password for root (enter for none): #输入当前密码，没有则直接按【Enter】键
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 #是否设置新密码
New password: #输入新密码
Re-enter new password: #确认新密码
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 #是否去掉匿名用户
... 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 #是否禁止root用户远程登录
... 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 #是否去掉测试数据库
- 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 #是否重新加载权限表
... 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!

4.RabbitMQ消息队列服务
消息队列（Message Queue，MQ）是一种应用间的通信方式，消息发送到消息队列后由消息队列来确保消息的可靠传递，即消息发布者和消息使用者之间并不产生直接关系。
OpenStack各个组件之间就是通过消息队列进行相互通信的。其中RabbitMQ是一个开源的、应用广泛的消息服务系统。
通常使用RabbitMQ为OpenStack提供消息队列服务。
# 安装RabbitMQ消息队列
[root@controller my.cnf.d]# yum install -y rabbitmq-server

Memcached的配置文件为/etc/sysconfig/memcached
[root@rabbitmq ~]# vi /etc/sysconfig/memcached
[root@rabbitmq ~]# cat /etc/sysconfig/memcached
PORT="11211" # 服务端口
USER="memcached" # 用户名

６.etcd分布式键值对存储系统
etcd是一个开源项目，它的目标是构建一个高可用的分布式键-值(Key-Value)数据库用于配置共享和服务发现。
这个软件的作用类似于分布式系统中“/etc”目录的功能，即存储大规模分布式系统的配置信息。
6.1安装配置

三、集群配置
1.1克隆计算节点和配置计算节点
# 修改网络配置
[root@controller ~]# cd /etc/sysconfig/network-scripts/
# 生产新的uuid
[root@controller network-scripts]# uuidgen >> ifcfg-ens33
# 修改ifcfg-ens33配置
NAME=ens33
UUID=80d04405-642e-41f6-aa31-a33b79b92ca4 # 将新生成的uuid放这里替换
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.100.132 # 修改网卡地址
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=114.114.114.114
DNS2=8.8.8.8
# 重启网络
[root@controller network-scripts]# systemctl restart network
# 更改计算节点主机名
[root@rabbitmq ~]# hostnamectl set-hostname compute
[root@rabbitmq ~]# bash
1.2域名解析配置
# 修改控制节点本地域名解析
[root@controller ~]# echo '192.168.100.132 compute' >> /etc/hosts
[root@controller ~]# ping compute
PING compute (192.168.100.132) 56(84) bytes of data.

1.3搭建本地软件仓库
不能访问外网的环境，需要搭建本地的YUM源。
没必要在每台机器上都配置同样的软件仓库，可以选择共享的方式为其他主机提供服务。
在控制节点配置YUM源，并搭建文件传输服务器为其他的计算节点提供服务。
1.3.1在控制节点配置YUM源
# 1.上传openStack-train.iso文件到/opt目录下
[root@controller opt]# ls
openStack-train.iso
# 2.将镜像文件挂载到文件夹中，即可访问镜像文件内容
[root@controller opt]# mkdir openstack
# 挂载命令：将镜像文件挂载到/opt/openstack
[root@controller opt]# mount openStack-train.iso openstack/
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller opt]# df -H
Filesystem Size Used Avail Use% Mounted on
devtmpfs 942M 0 942M 0% /dev
tmpfs 954M 0 954M 0% /dev/shm
tmpfs 954M 9.9M 944M 2% /run
tmpfs 954M 0 954M 0% /sys/fs/cgroup
/dev/mapper/centos-root 29G 20G 9.1G 69% /
/dev/sda1 1.1G 196M 868M 19% /boot
tmpfs 191M 0 191M 0% /run/user/0
/dev/loop0 17G 17G 0 100% /opt/openstack
# 3.备份原有的yum的配置文件
[root@controller opt]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# ls
CentOS-Base.repo CentOS-Media.repo CentOS-Storage-common.repo
CentOS-Ceph-Nautilus.repo CentOS-NFS-Ganesha-28.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-OpenStack-train.repo CentOS-x86_64-kernel.repo
CentOS-Debuginfo.repo CentOS-QEMU-EV.repo repo.bak
CentOS-fasttrack.repo CentOS-Sources.repo
# 将阿里源改名，避免覆盖官方源备份
[root@controller yum.repos.d]# mv CentOS-Base.repo CentOS-ALIBABA-Base.repo
# 移动repo文件到备份目录
[root@controller yum.repos.d]# mv -f *.repo repo.bak/
# 4.编写本地YUM源文件，指向本地文件
[root@controller yum.repos.d]# vi OpenStack.repo
[root@controller yum.repos.d]# cat OpenStack.repo
[base]

1.2keystone组件初始化
keystone安装后，需要为keystone初始化密钥库、初始化用户身份认证信息、初始化服务....
# 1.初始化Fernet密钥库
[root@controller ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
# 执行命令后创建/etc/keystone/fernet-keys,并在目录中生成两个fernet密钥，分别用于加密和解密
[root@controller ~]# cd /etc/keystone/fernet-keys
[root@controller fernet-keys]# pwd
/etc/keystone/fernet-keys
[root@controller fernet-keys]# du -sh *
4.0K 0
4.0K 1
[root@controller fernet-keys]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
# 执行命令后创建/etc/keystone/credential-keys目录，生成两个fetnet密钥，用于加密/解密用户凭证
[root@controller fernet-keys]# cd /etc/keystone/credential-keys
[root@controller credential-keys]# pwd
/etc/keystone/credential-keys
[root@controller credential-keys]# du -sh *
4.0K 0
4.0K 1
# 2.初始化用户身份认证信息
# openstack默认有一个admin用户，还没有对应的密码等登录所必须的信息。使用 `keystone-manage bootstrap` 初始化登录凭证。
[root@controller credential-keys]# keystone-manage bootstrap --bootstrap-password 000000 \
> --bootstrap-admin-url http://controller:5000/v3 \
> --bootstrap-internal-url http://controller:5000/v3 \
> --bootstrap-public-url http://controller:5000/v3 \
> --bootstrap-region-id RegionOne
设置区域ID
# 命令执行后，keystone数据库中就已经存放了登录需要的验证信息。
# 3.配置web服务
# （1）给apache增加wsgi支持
# 将wsgi-keystone.conf文件软链接到'/etc/httpd/conf.d/目录'，作为apache的配置文件
[root@controller credential-keys]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
[root@controller credential-keys]# ls /etc/httpd/conf.d/
autoindex.conf README userdir.conf welcome.conf wsgi-keystone.conf
# （2）修改apache服务器配置并启动
[root@controller credential-keys]# vi /etc/httpd/conf/httpd.conf
# 修改为web服务所在的IP地址或域名
96 ServerName controller
# （3）启动apache
[root@controller credential-keys]# systemctl start httpd
[root@controller credential-keys]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
1.3模拟登录验证
通过环境变量可以出传送用户名和密码等凭证给keystone，再由它验证。
# 创建一个文件存储身份凭证
[root@controller credential-keys]# vi admin-login
[root@controller credential-keys]# cat admin-login
export OS_USERNAME=admin
export OS_PASSWORD=000000
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
# 导入环境变量
[root@controller credential-keys]# source admin-login
# 查看现有环境信息
[root@controller credential-keys]# export -p

1.4检测keystone服务
openstack平台所有对组件的操作都需要keystone认证才能进行，能执行openstack管理命令，说明keystone服务正常。
