篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了私有云搭建 OpenStack（centos7.3, centos-release-openstack-liberty） （上篇）相关的知识，希望对你有一定的参考价值。
环境准备
hostname：linux-node1.oldboyedu.com
计算节点：
hostname：linux-node2.oldboyedu.com
ip地址：192.168.1.32
vi /etc/sysconfig/network-scripts/ifcfg-ens33
BOOTPROTO=static
DEVICE=ens33
NM_CONTROLLLER=yes
NETMASK=255.255.255.0
重启网卡使设置生效
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
[[email protected] ~]# vi /etc/hostname
linux-node1
[[email protected] ~]# systemctlrestart NetworkManager
[[email protected] ~]# hostname
linux-node1
[[email protected] ~]# 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。
[[email protected] ~]# vi/etc/resolv.conf
vi /etc/resolv.conf
nameserver 223.6.6.6
安装时间同步
[[email protected] ~]# vi /etc/chrony.conf
[[email protected] ~]# systemctl enablechronyd.service
启动chronyd
[[email protected] ~]#systemctlstart chronyd.service
[[email protected] ~]#timedatectl set-timezone Asia/Shanghai
[[email protected] ~]#date
Thu Nov 2 16:23:07 CST 2017
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
[[email protected] ~]# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
[[email protected] ~]# yum update -y

解决：
http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
[[email protected] ~]#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
[[email protected] ~]# rpm -ivhcentos-release-openstack-liberty-1-3.el7.noarch.rpm
/etc/yum.repos.d/下生成CentOS-OpenStack-liberty.repo

安装RabbitMQ
[[email protected] ~]#yum install rabbitmq-server-y
[[email protected] ~]# 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.
[[email protected]~]#systemctl start rabbitmq-server.service
[[email protected]~]# netstat-ntlp
5672是rabbitmq端口号
新建Rabbitmq用户并授权
[[email protected]~]# rabbitmqctl add_user openstack openstack
Creatinguser "openstack" ...
[[email protected]~]#rabbitmqctl set_permissions openstack".*" ".*" ".*"
Settingpermissions for user "openstack" in vhost "/" ...
启用Rabbitmq的web管理插件
[[email protected]~]#rabbitmq-plugins list
[[email protected]~]# rabbitmq-pluginsenable rabbitmq_management
Thefollowing plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Applyingplugin configuration to [email protected] started 6 plugins.
重启Rabbitmq
[[email protected]~]#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
[[email protected]~]# netstat-lntup |grep 5672
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 6984/beam
tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 6984/beam
tcp6 0 0 :::5672 :::* 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
若想要监控Rabbit，即可使用下图中的API
