centos-release-openstack-rocky.noarch 1-1.el7.centos extras
centos-release-openstack-stein.noarch 1-1.el7.centos extras
centos-release-openstack-train.noarch 1-1.el7.centos extras
yum install centos-release-openstack-ocata #旧版本安装,需要yum源支持
yum install –y centos-release-openstack-queens.noarch
yum install -y https://rdoproject.org/repos/rdo-release.rpm

yum install -y python-openstackclient
yum install -y openstack-selinux
可以单独安装至其他服务器， openstack 的各组件都要使用数据库保存数据， 除了nova 使用
API 与其他组件进行调用之外

cd /usr/local/src
安装erlang
wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
安装rpm仓库
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
安装erlang
yum -y install erlang
安装RabbitMQ
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.6/rabbitmq-server-3.6.6-1.el6.noarch.rpm
yum -y install rabbitmq-server-3.6.6-1.el6.noarch.rpm
启动rabbitmq服务:
service rabbitmq-server start
[root@linux-host5 ~]# service rabbitmq-server start
Starting rabbitmq-server (via systemctl): [ OK ]
安装插件
启动web管理界面
rabbitmq-plugins enable rabbitmq-management
增加访问用户，默认用户guest只能本地访问。
rabbitmqctl add_user admin passwd
设置角色：
rabbitmqctl set_user_tags admin administrator
设置默认vhost（"/"）访问权限
rabbitmqctl set_permissions -p "/" admin "." "." ".*"
浏览器访问：http://IP:15672
用户名admin，密码passwd进行登录
最好登录console的时候，删除默认账户guest
yum install memcached -y
yum install python-memcached –y
