【部署思路】

一、配置操作系统+OpenStack运行环境
    二、配置OpenStack平台基础服务（rabbitmq、mariadb、memcache、Apache)
    三、配置OpenStack keystone组件
    四、配置OpenStack Glance组件
    五、配置placement服务
    六、配置OpenStack Nova组件
    七、配置OpenStack Neutron组件
    八、配置OpenStack dashboard组件
    九、配置OpenStack Cinder组件
    十、常用云主机操作

Linux系统：最小化安装CentOS7.6

### 1.2 基础环境配置 ###

配置项（所有节点）：

1.  主机名

hostnamectl set-hostname <主机名>
    bash

1.  防火墙、核心防护

systemctl disable firewalld
    systemctl stop firewalld
    setenforce 0
    vi /etc/selinux/config
    SELINUX=disabled

1.  免交互

*  添加hosts文件

vi /etc/hosts
    192.168.100.100  controller
    192.168.100.101  compute1
    192.168.100.102  compute2
    PS：以上为局域网IP

*  非对称密钥

ssh-keygen -t rsa	
    ssh-copy-id controller
    ssh-copy-id compute1
    ssh-copy-id compute2

1.  基础环境依赖包

yum -y install net-tools bash-completion vim gcc gcc-c++ make pcre  pcre-devel expat-devel cmake  bzip2 
    yum -y install centos-release-openstack-train python-openstackclient openstack-selinux openstack-utils

5、时间同步

*  controller节点配置

yum install chrony -y
    vim /etc/chrony.conf 
    3 #server 0.centos.pool.ntp.org iburst
    4 #server 1.centos.pool.ntp.org iburst
    5 #server 2.centos.pool.ntp.org iburst
    6 #server 3.centos.pool.ntp.org iburst
    7 server ntp.aliyun.com iburst      '  //iburst:一次发8个包而不是一个包  '
    17 rtcsync       '  自动同步时间，比ntpdate方便   '
    27 allow 192.168.100.0/24       
    ' 注释掉3~6行，添加第7行  '

systemctl enable chronyd
    systemctl restart chronyd

*  使用 chronyc sources 命令查询时间同步信息

chronyc sources

**compute1,compute2节点时间同步设置基本相同，只需指明同步源为controller即可。**

yum install chrony -y
    vim /etc/chrony.conf 
    server controller iburst
    systemctl enable chronyd
    systemctl restart chronyd
    chronyc sources

## 二、OpenStack系统环境配置 ##

配置服务（控制节点）：

### 2.1 安装、配置MariaDB ###

1.  安装Mariadb和必要环境

yum -y install mariadb mariadb-server python2-PyMySQL
    #此包用于openstack的控制端连接mysql所需要的模块，如果不安装，则无法连接数据库；此包只安装在控制端

yum -y install libibverbs	  
    '    // A library and drivers for direct userspace use of RDMA (InfiniBand/iWARP/RoCE) hardware  '

1.  添加MySQL子配置文件，增加如下内容

vim /etc/my.cnf.d/openstack.cnf
    [mysqld]
    bind-address = 192.168.100.100
    default-storage-engine = innodb
    innodb_file_per_table = on
    max_connections = 4096
    collation-server = utf8_general_ci
    character-set-server = utf8

1.  开机自启动、开启服务

systemctl enable mariadb
    systemctl start mariadb

1.  执行MariaDB 安全配置脚本交互式地初始化mariadb

mysql_secure_installation
    Enter current password for root (enter for none): 			#回车
    OK, successfully used password, moving on...
    Set root password? [Y/n] Y
    Remove anonymous users? [Y/n] Y
     ... Success!
    Disallow root login remotely? [Y/n] N
     ... skipping.
    Remove test database and access to it? [Y/n] Y 
    Reload privilege tables now? [Y/n] Y

### 2.2 安装，配置RabbitMQ ###

所有创建虚拟机的指令，控制端都会发送到rabbitmq，node节点监听rabbitmq

1.  安装RabbitMQ

yum -y install rabbitmq-server

1.  启动RabbitMQ服务，并设置其开机启动。

systemctl enable rabbitmq-server.service
    systemctl start rabbitmq-server.service

1.  创建MQ(消息队列)用户"openstack",用于controler和node节点连接rabbitmq的认证

rabbitmqctl add_user openstack RABBIT_PASS

1.  配置openstack用户的操作权限(正则，配置读写权限）

rabbitmqctl set_permissions openstack ".*" ".*" ".*"
    '  //Rabbitmq set_permissions [-p <vhost>] <user> <conf> <write> <read>  '

\#可查看25672和5672 两个端口（5672是Rabbitmq默认端口，25672是Rabbit的测试工具CLI的端口）

1.  查看rabbitmq插件列表、开启rabbitmq的web管理界面的插件

rabbitmq-plugins list
    rabbitmq-plugins enable rabbitmq_management
    netstat -anptu | grep 5672

使用192.168.100.100:15672或者20.0.0.100均可访问RabbitMQ  
默认账号密码均为guest

### 2.3 安装memcached ###

*  作用
    
     *  安装memcached是用于存储session信息服务
     *  身份验证机制使用Memcached来缓存令牌 在登录openstack的dashboard时，会产生一些session信息，这些session信息会存放到memcached中
 *  安装Memcached

yum install -y memcached python-memcached
    '   //python-*模块在OpenStack中起到连接数据库的作用  '

*  修改Memcached配置文件

vim /etc/sysconfig/memcached 
    PORT="11211"
    USER="memcached"
    MAXCONN="1024"
    CACHESIZE="64"
    OPTIONS="-l 127.0.0.1,::1,controller"     '  //仅添加controller    '

*  开机自启动

systemctl enable memcached
    systemctl start memcached
    netstat -nautp | grep 11211

### 2.4 安装、配置etcd ###

1.  安装etcd

yum -y install etcd

1.  修改etcd配置文件

vim /etc/etcd/etcd.conf 
    1 #[Member]
    3 ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
    5 ETCD_LISTEN_PEER_URLS="http://192.168.100.100:2380"
    6 ETCD_LISTEN_CLIENT_URLS="http://192.168.100.100:2379"	
    9 ETCD_NAME="controller"	
    19 #[Clustering]
    20 ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.100.100:2380"
    21 ETCD_ADVERTISE_CLIENT_URLS="http://192.168.100.100:2379
    26 ETCD_INITIAL_CLUSTER="controller=http://192.168.100.100:2380"	
    27 ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"		#集群唯一标识
    28 ETCD_INITIAL_CLUSTER_STATE="new"   #初始集群状态，new为静态，若为existing，则表示此ETCD服务将尝试加入已有的集群
    若为DNS，则表示此集群将作为被加入的对象

1.  开机自启动、开启服务，检测端口

systemctl enable etcd.service
    systemctl start etcd.service
    netstat -anutp |grep 2379
    netstat -anutp |grep 2380
