环境准备

控制节点

hostname：linux-node1.oldboyedu.com

ip地址：192.168.1.31

计算节点：

hostname：linux-node2.oldboyedu.com

ip地址：192.168.1.32

先配置控制节点192.168.1.31

vi /etc/sysconfig/network-scripts/ifcfg-ens33

BOOTPROTO=static

DEVICE=ens33

NM_CONTROLLLER=yes

IPADDR=192.168.1.31

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

重启网卡使设置生效

nmcli connection down ens33

nmcli connection up ens33

修改主机名

需要修改两处：一处是/etc/hostname，另一处是/etc/hosts

[root@localhost ~]# vi /etc/hostname

linux-node1

[root@localhost ~]# systemctlrestart NetworkManager

[root@localhost ~]# hostname

linux-node1

[root@localhost ~]# vi /etc/hosts

192.168.1.31   linux-node1      linux-node1.oldboyedu.com

192.168.1.32   linux-node2      linux-node2.oldboyedu.com

将上面两个文件修改完后，并不能立刻生效。如果要立刻生效的话，可以用 hostname your-hostname 作临时修改，它只是临时地修改主机名，系统重启后会恢复原样的。

hostname linux-node1

设置DNS服务器的IP

[root@linux-node1 ~]# vi/etc/resolv.conf

vi /etc/resolv.conf

nameserver 223.6.6.6

安装时间同步

yuminstall chrony

[root@localhost ~]# vi /etc/chrony.conf

allow 192.168.0.0/16

设置开机自启动

[root@localhost ~]# systemctl enablechronyd.service

启动chronyd

[root@localhost ~]#systemctlstart chronyd.service

[root@localhost ~]#timedatectl set-timezone Asia/Shanghai

[root@localhost ~]#date

关闭 selinux(centos7.3需要改2个地方/etc/sysconfig/selinux和/etc/selinux/config )
sed -i ‘s#SELINUX=enforcing#SELINUX=disabled#g‘/etc/sysconfig/selinux

sed -i‘s#SELINUX=enforcing#SELINUX=disabled#g‘ /etc/selinux/config
setenforce 0

getenforce可查看selinux的状态

关闭 iptables
systemctl stop firewalld.service
systemctl disable firewalld.service

[root@localhost ~]# cat /etc/redhat-release

解决：

http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

[root@linux-node1 ~]#rpm -ivhepel-release-7-11.noarch.rpm

/etc/yum.repos.d/下生成epel-testing.repo和epel.repo

https://buildlogs.centos.org/centos/7/cloud/x86_64/openstack-liberty/centos-release-openstack-liberty-1-3.el7.noarch.rpm

[root@linux-node1 ~]# rpm -ivhcentos-release-openstack-liberty-1-3.el7.noarch.rpm

/etc/yum.repos.d/下生成CentOS-OpenStack-liberty.repo

[root@linux-node1 ~]# yum clean all

[root@linux-node1 ~]# yum clean metadata

之后运行yum makecache生成缓存

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

MySQL

[root@localhost yum.repos.d]#yum install mariadbmariadb-server MySQL-python -y

[root@localhost yum.repos.d]# cp /usr/share/mariadb/my-medium.cnf /etc/my.cnf

[root@localhostyum.repos.d]# vi /etc/my.cnf

[mysqld]

安装RabbitMQ

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

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

Createdsymlink from/etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to/usr/lib/systemd/system/rabbitmq-server.service.

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

[root@localhost~]# netstat-ntlp

5672是rabbitmq端口号

新建Rabbitmq用户并授权

[root@localhost~]#  rabbitmqctl add_user openstack openstack

Creatinguser "openstack" ...

[root@localhost~]#rabbitmqctl set_permissions openstack".*" ".*" ".*"

Settingpermissions for user "openstack" in vhost "/" ...

启用Rabbitmq的web管理插件

[root@localhost~]#rabbitmq-plugins list

[root@localhost~]# rabbitmq-pluginsenable rabbitmq_management

Thefollowing plugins have been enabled:

  mochiweb

  webmachine

  rabbitmq_web_dispatch

  amqp_client

  rabbitmq_management_agent

  rabbitmq_management

Applyingplugin configuration to rabbit@localhost... started 6 plugins.

重启Rabbitmq

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

查看Rabbit的端口，其中5672是服务端口，15672是web管理端口，25672是做集群的端口

[root@localhost~]# netstat-lntup |grep 5672

tcp        0     0 0.0.0.0:15672          0.0.0.0:*               LISTEN      6984/beam

登陆http://192.168.1.31:15672 （用户名：guest密码：guest）

http://192.168.1.31:15672/#/users

点openstack

点update this user

密码中输入：openstack，Tags: administrator

再登陆http://192.168.1.31:15672（用户名：openstack密码：openstack）

现在已经有了2个用户可以登陆
