CentOS7.2部署OpenStack（一）—环境准备

本篇文章介绍CentOS7.2部署OpenStack，具体如下：

1、系统环境

# uname -r

3.10.0-327.el7.x86_64

# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

2、服务器部署

3、基础环境准备

3.1、配置hosts

# cat /etc/hosts

192.168.56.108 controller

192.168.56.109 compute

3.2、配置时间同步

[root@controller ~]# yum install -y ntp

[root@controller ~]# vim /etc/ntp.conf

15 restrict -6 ::1

16 restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

27 restrict 0.centos.pool.ntp.org nomodify notrap noquery

28 restrict 1.centos.pool.ntp.org nomodify notrap noquery

29 restrict 2.centos.pool.ntp.org nomodify notrap noquery

30 restrict 3.centos.pool.ntp.org nomodify notrap noquery

31 server 127.127.1.0

32 fudge 127.127.1.0 stratum 10

[root@controller ~]# systemctl enable ntpd

[root@controller ~]# systemctl start ntpd

在控制节点和计算节点配置定时任务

[root@compute ~]# crontab -l */5 * * * * /usr/sbin/ntpdate 192.168.56.108 >/dev/null 2>&1

3.3、关闭防火墙

# systemctl stop firewalld

3.4、关闭selinux

# SELINUX=disabled /etc/selinux/config //需要重启

3.5、安装基础包

[root@controller ~]# yum install -yhttp://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-7.noarch.rpm

[root@controller ~]# yum install -y centos-release-openstack-liberty

[root@controller ~]# yum install -y python-openstackclient

3.6、安装mysql

[root@controller ~]# yum install -y mariadb mariadb-server MySQL-python

[root@controller ~]# vim /etc/my.cnf

在mysqld模块添加如下几行：

default-storage-engine = innodb

innodb_file_per_table

collation-server = utf8_general_ci 

init-connect = 'SET NAMES utf8'

character-set-server = utf8

[root@controller ~]# systemctl enable mariadb.service

[root@controller ~]# systemctl start mariadb.service

[root@controller ~]# mysql_secure_installation

3.7、安装rabbitmq

[root@controller ~]# yum install -y rabbitmq-server

[root@controller ~]# systemctl enable rabbitmq-server.service

[root@controller ~]# systemctl start rabbitmq-server.service

[root@controller ~]# rabbitmqctl add_user openstack openstack

Creating user "openstack" ...

...done.

[root@controller ~]# rabbitmqctl set_permissions openstack '.*' '.*' '.*'

Setting permissions for user "openstack" in vhost "/"...

...done.

[root@controller ~]# rabbitmqctl set_user_tags openstack administrator

[root@controller ~]# rabbitmq-plugins enable rabbitmq_management

[root@controller ~]# systemctl restart rabbitmq-server.service

在浏览器中输入http://192.168.56.108:15672，默认账户和密码为guest

登录后将前面创建的openstack用户加入到admin中，结果如下图：
