初識openstack之4——opsenstack安裝前準備

一、實驗說明

按照官方文檔搭建queens版本openstack，拓撲如下圖所示：

二、實驗目的

準備好openstack元件安裝前所需要的其他軟體，如MariaDB，RabbitMQ等。

三、操作步驟

修改所有節點/etc/hosts檔案

如果hosts檔案中有将主機名解析到127.0.0.1的配置段，将其登出

所有節點關閉NetworkManager

[[email protected] ~]# systemctl stop NetworkManager.service

[[email protected] ~]# systemctl disable NetworkManager.service

所有節點添加openstack需要的yum源

[[email protected] ~]# vim /etc/yum.repo.d/OpenStack-Queens.repo

[OpenStack-Queens]
name=OpenStack-Queens
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-queens/
enable=1
gpgcheck=0
           

安裝NTP服務

controller節點進行以下操作：

1. 安裝并設定允許同步的網段

   [[email protected] ~]# yum install chrony

   [[email protected] ~]# vim /etc/chrony.conf

   allow 172.16.80.0/24
              

2. 啟動NTP服務并同步測試

   [[email protected] ~]# systemctl enable chronyd.service

   [[email protected] ~]# systemctl start chronyd.service

   [[email protected] ~]# chronyc sources

   

其他節點進行以下操作：

1. 安裝NTP并設定向controller進行時間同步

   [[email protected] ~]# yum install chrony

   [[email protected] ~]# vim /etc/chrony.conf

   server controller iburst
              

2. 啟動服務并驗證同步

   [[email protected] ~]# systemctl enable chronyd.service

   [[email protected] ~]# systemctl start chronyd.service

   [[email protected] ~]# chronyc sources

   

安裝資料庫

1. 安裝并編輯配置檔案

   [[email protected] ~]# yum install mariadb mariadb-server python2-PyMySQL

   [[email protected] ~]# vim /etc/my.cnf.d/openstack.cnf

   [mysqld]
   bind-address = 172.16.80.10
   default-storage-engine = innodb
   innodb_file_per_table = on
   max_connections = 4096
   collation-server = utf8_general_ci
   character-set-server = utf8
   skip_name_resolve = 1
              

2. 啟動資料庫

   [[email protected] ~]# systemctl enable mariadb.service

   [[email protected] ~]# systemctl start mariadb.service

安裝消息中間件

1. 安裝rabbitmq中間件

   [[email protected] ~]# yum install rabbitmq-server

2. 加載rabbitmq_management插件啟用圖形界面

   [[email protected] ~]# rabbitmq-plugins enable rabbitmq_management

   [[email protected] ~]# systemctl start rabbitmq-server.service

3. 為openstack建立使用者并授權

   [[email protected] ~]# rabbitmqctl add_user openstack password1!

   [[email protected] ~]# rabbitmqctl set_permissions openstack "." "." ".*"

安裝認證緩存

1. 安裝程式包

   [[email protected] ~]# yum install memcached python-memcached

2. 配置并啟用程式

   [[email protected] ~]# vim /etc/sysconfig/memcached

   

   [[email protected] ~]# systemctl enable memcached.service

   [[email protected] ~]# systemctl start memcached.service

安裝分布式密鑰存儲

1. 下載下傳安裝包

   [[email protected] ~]# yum install etcd

2. 編輯配置檔案并啟動

   [[email protected] ~]# vim /etc/etcd/etcd.conf

   #[Member]
   ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
   ETCD_LISTEN_PEER_URLS="http://172.16.80.10:2380"
   ETCD_LISTEN_CLIENT_URLS="http://172.16.80.10:2379"
   ETCD_NAME="controller"
   #[Clustering]
   ETCD_INITIAL_ADVERTISE_PEER_URLS="http://172.16.80.10:2380"
   ETCD_ADVERTISE_CLIENT_URLS="http://172.16.80.10:2379"
   ETCD_INITIAL_CLUSTER="controller=http://172.16.80.10:2380"
   ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
   ETCD_INITIAL_CLUSTER_STATE="new"
              

   [[email protected] ~]# systemctl enable etcd

   [[email protected] ~]# systemctl start etcd

至此，openstack安裝前準備工作全部完成。
