# 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/hosts192.168.56.108 controller192.168.56.109 compute

3.2、配置时间同步

[root@controller ~]# yum install -y ntp[root@controller ~]# vim /etc/ntp.conf15 restrict -6 ::116 restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap27 restrict 0.centos.pool.ntp.org nomodify notrap noquery28 restrict 1.centos.pool.ntp.org nomodify notrap noquery29 restrict 2.centos.pool.ntp.org nomodify notrap noquery30 restrict 3.centos.pool.ntp.org nomodify notrap noquery31 server 127.127.1.032 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 = innodbinnodb_file_per_tablecollation-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 openstackCreating 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：
