·
一：单节点拓扑
外部网络：192.168.1.0/24
内部网络：172.16.1.0/24
二：实验环境准备
2.1：创建虚拟机并安装操作系统
使用CentOS 7.2
安装时传递内核参数 net.ifnames=0 biosdevname=0 ，以使安装后的系统网卡名称标准化（eth*）。
2.2：系统初始环境准备
2.2.1：基本初始化
参见《CentOS系统初始化.md》
2.2.2：配置域名/主机名解析
- 各节点采用内网网段通信，解析主机名为内网地址：
]# vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.1.101 node101.yqc.com node101
172.16.1.102 node102.yqc.com node102
172.16.1.103 node103.yqc.com node103
172.16.1.104 node104.yqc.com node104
2.3：设置虚拟机网络环境
2.3.1：Openstack 控制端网络设置

在每个服务器上ping另外三个服务器的域名和主机名，以node101为例：

2.3.6：手动同步NTP
虽然系统初始化配置时已设置crontab任务计划来自动同步NTP时间，但为了防止计划任务的时长导致服务器之间时间还未同步，在开始安装配置Openstack前手动同步一遍NTP。
另外，因为内网没有NTP服务器，基础服务节点向node101同步时间。
将node101 配置为内网NTP服务端
]# yum install chrony -y
]# vim /etc/chrony.conf
# 配置node101向外网NTP服务器192.168.1.254同步时间；
server 192.168.1.254 iburst
# 允许内网网段172.16.1.0/24向node101同步时间；
allow 172.16.1.0/24
# 启动chronyd服务；
]# systemctl start chronyd
]# systemctl enable chronyd
其他节点配置NTP自动同步任务计划
# 手动同步；
]# ntpdate 172.16.1.101
29 Oct 21:26:20 ntpdate[9636]: step time server 172.16.1.101 offset 4502.960252 sec
# 添加crontab计划任务；
]# echo "*/30 * * * * /usr/sbin/ntpdate 172.16.1.101 && /usr/sbin/hwclock -w" > /var/spool/cron/root
]# crontab -l
*/30 * * * * /usr/sbin/ntpdate 172.16.1.101 && /usr/sbin/hwclock -w
至此，搭建单机Openstack的基础环境准备完毕。
三：Openstack 环境准备
3.1：基础服务节点安装MariaDB
- 为了方便安装，先将node102的网络改为外网，yum安装完成后改回内网网址：
需要先将node102的网卡改为桥接模式；
]# vim /etc/sysconfig/network-scripts/ifcfg-bond0

PREFIX="24"
GATEWAY="192.168.1.1"
DNS1="192.168.1.254"
]# systemctl restart network
3.1.1：安装mariadb-server
]# yum install mariadb mariadb-server -y
3.1.2：编辑主配置文件
]# cp /etc/my.cnf /etc/my.cnf.bak
]# vim /etc/my.cnf
[mysqld]
socket=/var/lib/mysql/mysql.sock
user=mysql
symbolic-links=0

port=3306
socket=/var/lib/mysql/mysql.sock
[mysqld_safe]
log-error=/data/mysql-log/mysqld_safe.log
pid-file=/var/run/mariadb/mariadb.pid
3.1.3：编辑 Openstack自定义配置文件
]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
# 指定监听地址
bind-address = 172.16.1.102
# 默认引擎
default-storage-engine = innodb
# 开启每个表都有独立表空间
innodb_file_per_table = on
# 最大连接数
max_connections = 4096
# 不区分大小写排序
collation-server = utf8_general_ci
# 设置编码
character-set-server = utf8
3.1.4：创建数据目录并授权
]# mkdir -pv /data/{mysql,mysql-log,mysql-binlog}
]# chown mysql:mysql /data/mysql* -R
3.1.5：启动 MariaDB 并验证端口
]# systemctl start mariadb
]# systemctl enable mariadb
]# ss -tnl
3.1.6：初始化安全配置
]# mysql_secure_installation
3.2：基础服务节点安装RabbitMQ
3.2.1：配置 EPEL yum源
安装RabbitMQ需要配置EPEL源。
]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
]# yum clean all
]# yum makecache
3.2.2：安装rabbitmq-server
]# yum install rabbitmq-server httpd -y
3.2.3：启动 RabbitMQ 及 web管理插件
]# systemctl start rabbitmq-server httpd
]# systemctl enable rabbitmq-server httpd
]# rabbitmq-plugins enable rabbitmq_management
]# ss -tnl
]# rabbitmq-plugins list
RabbitMQ在启动并打开web插件后，有三个监听端口：5672、15672、25672；
3.2.4：RabbitMQ 中添加openstack用户并授权
]# rabbitmqctl add_user openstack 123456
]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
RabbitMQ默认有一个guest/guest用户；
3.3：基础服务节点安装Memcached
3.3.1：安装memcached
]# yum install memcached -y
3.3.2：编辑配置文件

[ocata]
name=Openstack-Ocata
baseurl=https://mirrors.aliyun.com/centos-vault/7.4.1708/cloud/x86_64/openstack-ocata/
gpgcheck=0
]# yum clean all
]# yum makecache

四：部署 keystone 认证服务
4.1：keystone 数据库准备
4.1.1：创建数据库并授权 keystone 用户
]# mysql -uroot -p
MariaDB [(none)]> CREATE DATABASE keystone;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '123456';
MariaDB [(none)]> flush privileges;
4.1.2：验证数据库远程连接
- 在控制端 node101 上远程连接数据库：
]# mysql -h172.16.1.102 -ukeystone -p
]# mysql -hnode102 -ukeystone -p
]# mysql -hnode102.yqc.com -ukeystone -p
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| keystone |
+--------------------+
4.2：安装及配置 keystone
4.2.1：控制端安装 keystone
]# yum install openstack-keystone httpd mod_wsgi -y
4.2.2：编辑 keystone 配置文件
- 生成临时token：
]# openssl rand -hex 10
48ed35f5a9afb2b6973c
- 编辑 /etc/keystone/keystone.conf ：
]# vim /etc/keystone/keystone.conf
[DEFAULT]
admin_token = 48ed35f5a9afb2b6973c
[database]
connection = mysql+pymysql://keystone:123456@node102.yqc.com/keystone
[token]
provider = fernet
4.2.3：初始化keystone数据库
- 初始化数据库：
]# su -s /bin/sh -c "keystone-manage db_sync" keystone
- 验证结果：
]# mysql -hnode102 -ukeystone -p
MariaDB [(none)]> use keystone;
MariaDB [keystone]> show tables;
+------------------------+
| Tables_in_keystone |
+------------------------+
| access_token |
| assignment |
| config_register |
| consumer |
| credential |
| endpoint |
| endpoint_group |
| federated_user |
| federation_protocol |
……
keystone的日志文件为：/var/log/keystone/keystone.log；
4.2.4：初始化Fernet key
- 初始化证书：
]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
- 验证：
]# ll /etc/keystone/fernet-keys/
total 8
-rw------- 1 keystone keystone 44 Oct 31 18:51 0
-rw------- 1 keystone keystone 44 Oct 31 18:51 1
官方文档中采用的是自动初始化keystone认证服务的方式，初次安装不要执行这个命令，因为对openstack不熟悉，最好还是手动操作一下；并且这个命令中需要ADMIN_PASS，而到目前为止还都不知道admin的密码是什么；
以下为官方文档自动初始化keystone认证服务命令：
Bootstrap the Identity service
]# keystone-manage bootstrap --bootstrap-password ADMIN_PASS \ --bootstrap-admin-url http://controller:35357/v3/ \ --bootstrap-internal-url http://controller:5000/v3/ \ --bootstrap-public-url http://controller:5000/v3/ \ --bootstrap-region-id RegionOne
4.3：配置 Apache 服务
4.3.1：编辑httpd主配置文件：
]# vim /etc/httpd/conf/httpd.conf
ServerName node101.yqc.com:80
4.3.2：软链接 wsgi-keystone.conf 至 httpd 配置文件目录中：
]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
4.3.3：启动 httpd 并验证：
]# systemctl start httpd
]# systemctl enable httpd
]# ss -tnl | egrep "(5000|80|35357)"
LISTEN 0 511 :::35357 :::*
LISTEN 0 511 :::5000 :::*
LISTEN 0 511 :::80 :::*
4.3.4：设置环境变量
以拥有admin的权限；
]# export OS_TOKEN=48ed35f5a9afb2b6973c
]# export OS_URL=http://node101.yqc.com:35357/v3
]# export OS_IDENTITY_API_VERSION=3
一定要在设置环境变量之后再进行后续操作；

首轮安装没成功，未找到原因，只想着是不是因为安装配置的顺序搞乱导致的，没有仔细检查；
]# neutron agent-list neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead. The server has either erred or is incapable of performing the requested operation.<br /><br /> Neutron server returns request_ids: ['req-6158d463-eb53-43de-9881-c50ed977f72b']第二次同样没成功，这次确信之前的步骤都是正确的，所以仔细查找原因：
neutron日志中找到一条报错：ValueError: Unable to parse connection string: “http://node102.yqc.com:11211”
neutron配置文件中的配置为：memcached_servers = http://node102.yqc.com:11211
改为：memcached_servers = node102.yqc.com:11211，重启neutron控制端；OK！
八：部署 neutron 计算节点
8.1：安装及配置neutron计算服务
8.1.1：安装neutron计算服务
]# yum install openstack-neutron-linuxbridge ebtables ipset -y
8.1.2：编辑neutron计算服务配置文件
计算节点不直接访问数据库，所以没有[database]配置；
]# vim /etc/neutron/neutron.conf
[DEFAULT]
auth_strategy = keystone
transport_url = rabbit://openstack:123456@node102.yqc.com
[keystone_authtoken]
auth_uri = http://node101.yqc.com:5000
auth_url = http://node101.yqc.com:35357
memcached_servers = node102.yqc.com:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = 123456
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
8.1.3：配置 linuxbridge 代理（提供者网络）
]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:bond1
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_security_group = true
[vxlan]
enable_vxlan = false
8.1.4：配置 linuxbridge 代理（自服务网络）
]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:bond1
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
enable_security_group = true
[vxlan]
enable_vxlan = true
local_ip = 192.168.1.103
l2_population = true
8.1.5：配置 nova 调用 neutron
- 编辑nova计算服务配置文件：
]# vim /etc/nova/nova.conf
[neutron]
url = http://node101.yqc.com:9696
auth_url = http://node101.yqc.com:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = 123456
- 重启nova计算服务：
]# systemctl restart openstack-nova-compute.service
8.1.6：启动 neutron 计算服务并设置为开机启动
]# systemctl enable neutron-linuxbridge-agent.service
]# systemctl start neutron-linuxbridge-agent.service
8.1.7：neutron计算服务日志
- 启动neutron计算服务后生成日志文件：
]# ll /var/log/neutron/
total 4
-rw-r--r-- 1 neutron neutron 1667 Nov 5 17:29 linuxbridge-agent.log
- 查看有无报错：
]# tail -f /var/log/neutron/*.log
8.2：验证 neutron 计算节点
8.2.1：neutron 控制端验证计算节点是否注册成功
]# neutron agent-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
