Centos7搭建OpenStack T版本 --上

1. 环境准备(所有节点操作)

主机名	IP
controller	192.168.100.100(仅主机) 192.168.200.X (NAT模式DHCP分配)
compute	192.168.100.200(仅主机) 192.168.200.X (NAT模式DHCP分配)

如果需要搭建存储节点则添加机器并配置网络即可，我的所有密码设置为123

1.1 修改主机名

所有节点都需要操作，且操作方法一样，只写了controller一个节点的结果，其他节点照常执行

IP地址自行配置

[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash

1.2 关闭selinux 以及防火墙

将默认的enforcing改为disabled

[root@controller ~]# cat /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=disabled
[root@controller ~]# setenforce 0
[root@controller ~]# systemctl disable --now firewalld

1.3 修改hosts

[root@controller ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
# 加上controller和compute，如果有其他节点也写进来
192.168.100.100 controller
192.168.100.110 compute

1.4 配置时间同步

controller 操作

[root@controller ~]# yum install chrony -y
[root@controller ~]# vim /etc/chrony.conf 
# controller节点需要改这三个地方
server ntp.aliyun.com iburst   # 中间的ntp服务器可自己改，能同步就行
allow 192.168.100.0/24    #允许192.168.100.0/24 这个网段内的主机与这台服务器同步
local stratum 10  
[root@controller ~]# chronyc sources
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
^* 203.107.6.88                  2   6    17     2   +319us[ +654us] +/-   23ms

compute以及其他节点操作

[root@compute ~]# yum install chrony -y
[root@compute ~]# vim /etc/chrony.conf
# 只需要改动一处地方
server controller iburst
[root@compute ~]# systemctl restart chronyd
[root@compute ~]# chronyc sources
210 Number of sources = 1
MS Name/IP address         Stratum Poll Reach LastRx Last sample               
===============================================================================
^* controller                    3   6     7     1  +6342ns[ -921us] +/-   29ms

1.5 配置OpenStack 软件包

[root@controller ~]# yum install centos-release-openstack-train -y
[root@controller ~]# yum install python2-openstackclient -y

1.6 安装数据库

从这里开始只需要在controller节点上操作，其他节点不需要操作

[root@controller ~]# yum install mariadb mariadb-server python2-PyMySQL
[root@controller ~]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
# 官网有这一条配置，我没有打开，打开之后不方便排错
# 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
[root@controller ~]# systemctl enable --now mariadb

数据库初始化

[root@controller ~]# mysql_secure_installation
Enter current password for root (enter for none): # 直接按回车
Change the root password? [Y/n]  # 是否修改root密码，按Y然后输入密码
Remove anonymous users? [Y/n] # 移除匿名用户，建议移除
Disallow root login remotely? [Y/n] # 是否禁止root远程登录，建议开启，按n
Remove test database and access to it? [Y/n] # 移除测试数据库，建议按Y
Reload privilege tables now? [Y/n] # 重新加载权限，按Y

1.7 安装消息队列

[root@controller ~]#  yum install rabbitmq-server -y
[root@controller ~]# systemctl enable rabbitmq-server.service --now
# 这个地方RABBIT_PASS 设置为你自己的密码，我用的123
# rabbitmqctl add_user openstack RABBIT_PASS
[root@controller ~]# rabbitmqctl add_user openstack 123
[root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

1.8 安装memcached

[root@controller ~]# yum install memcached python-memcached -y
[root@controller ~]# vim /etc/sysconfig/memcached
# 修改这一行，加上controller
OPTIONS="-l 127.0.0.1,::1,controller"
[root@controller ~]# systemctl enable memcached.service --now

1.9 安装etcd

[root@controller ~]# yum install etcd -y
# 直接清空原先的配置，使用这些，注意将192.178.100.100 改为你自己的controller的IP
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://192.168.100.100:2380"
ETCD_LISTEN_CLIENT_URLS="http://192.168.100.100:2379"
ETCD_NAME="controller"
#[Clustering]
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.100.100:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://192.168.100.100:2379"
ETCD_INITIAL_CLUSTER="controller=http://192.168.100.100:2380"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER_STATE="new"
[root@controller ~]# systemctl enable --now etcd

2. 安装Keystone

2.1 数据库操作

我的所有密码为123，之后不写注释了，你需要修改密码的话将123改为你想设的密码就好

[root@controller ~]# mysql -uroot -p123
# -p 后面跟上你的数据库root密码，如果不想这样直接显示登录的话可以直接-p 回车
MariaDB [(none)]> CREATE DATABASE keystone;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '123';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%'IDENTIFIED BY '123';
MariaDB [(none)]> glush privileges;

2.2 安装软件包

[root@controller ~]# yum install openstack-keystone httpd mod_wsgi -y
[root@controller ~]# vim /etc/keystone/keystone.conf
[database]
# 自己注意替换密码，123是你要替换的地方
connection = mysql+pymysql://keystone:123@controller/keystone
[token]
provider = fernet
[root@controller ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
[root@controller ~]#  keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@controller ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone


# 命令比较长，注意自行替换123
[root@controller ~]#  keystone-manage bootstrap --bootstrap-password 123 
  --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
[root@controller ~]# vim /etc/httpd/conf/httpd.conf
ServerName controller
[root@controller ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
[root@controller ~]# systemctl enable --now httpd

2.3 编写admin rc文件

[root@controller ~]# vim admin-login.sh
export OS_USERNAME=admin
export OS_PASSWORD=123
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

2.4 测试keystone是否正常工作

2.4.1 创建domain

[root@controller ~]# openstack domain create --description "An Example Domain" example

+-------------+----------------------------------+
| Field       | Value                            |

  --description "Service Project" service

+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+

| parent_id   | default                          |
| tags        | []                               |
+-------------+----------------------------------+
