一、每台机器设置固定ip，做免密，每台机器添加hosts文件解析，为每台机器设置主机名，关闭firewalld，selinux

 

vi /etc/hosts

10.2.2.2 controller

10.2.2.3 compute

10.2.2.4 network

 

设置主机名：

hostnamectl set-hostname controller

 

时间同步：

yum install chrony -y

vi /etc/chrony.conf

server controller iburst

allow 10.2.2.0/24

systemctl enable chronyd.service

systemctl start chronyd.service

验证：chronyc sources 在S那一列包含*号，代表同步成功

 

二、openstack准备

生成yum源repo文件：

#yum install centos-release-openstack-rocky -y

#yum upgrade -y

安装openstack客户端，安装好后就可执行openstack命令：

#yum install python-openstackclient -y

 

控制节点部署mariadb数据库：

yum install mariadb mariadb-server python2-PyMySQL -y

vi /etc/my.cnf.d/openstack.cnf

[mysqld]

bind-address = 10.2.2.2

default-storage-engine = innodb

innodb_file_per_table = on

max_connections = 4096

collation-server = utf8_general_ci

character-set-server = utf8

 

systemctl enable mariadb.service

systemctl start mariadb.service

mysql_secure_installation

root

123

 

控制节点部署消息队列：

#yum install rabbitmq-server -y

#systemctl enable rabbitmq-server.service

#systemctl start rabbitmq-server.service

新建rabbitmq用户密码，允许用户进行配置，写入，和读取访问openstack：

#rabbitmqctl add_user openstack 123

#rabbitmqctl set_permissions openstack ".*" ".*" ".*"

启用rabbitmq_management插件实现web管理：

#rabbitmq-plugins enable rabbitmq_management

#systemctl restart rabbitmq-server.service

#rabbitmq-plugins list | grep rabbitmq_management

#lsof -i:15672

http://10.2.2.2:15672/

默认用户和密码都是guest

 

控制节点部署memcached缓存：

#yum install memcached python-memcached -y

#vi /etc/sysconfig/memcached

OPTIONS="-l 127.0.0.1,::1,controller"

 

#systemctl enable memcached.service

#systemctl start memcached.service

 

控制节点部署etcd：

#yum install etcd -y

vi /etc/etcd/etcd.conf

#[Member]

ETCD_DATA_DIR="/var/lib/etcd/default.etcd"

ETCD_LISTEN_PEER_URLS="http://10.2.2.2:2380"

ETCD_LISTEN_CLIENT_URLS="http://10.2.2.2:2379"

ETCD_NAME="controller"

#[Clustering]

ETCD_INITIAL_ADVERTISE_PEER_URLS="http://10.2.2.2:2380"

ETCD_ADVERTISE_CLIENT_URLS="http://10.2.2.2:2379"

ETCD_INITIAL_CLUSTER="controller=http://10.2.2.2:2380"

ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"

ETCD_INITIAL_CLUSTER_STATE="new"

#systemctl enable etcd.service

#systemctl start etcd.service

验证：netstat -anptl|grep etcd
