這篇文章主要介紹了OpenStack云平臺Train版搭建與基礎環境準備的方法是什么的相關知識,內容詳細易懂,操作簡單快捷,具有一定借鑒價值,相信大家閱讀完這篇OpenStack云平臺Train版搭建與基礎環境準備的方法是什么文章都會有所收獲,下面我們一起來看看吧。
OpenStack是由美國國家航空航天局NASA)與Rackspace公司合作研發并發起的,以Apache許可證授權的自由軟件和開放源代碼的云計算技術解決方案,其是一個項目也是一個軟件,主要用于實現云項目,以云項目操作系統而存在。作用: 用于部署公有云、私有云,并實現對云項目管理。
開發語言: Python
名稱 | IP地址 | 主機名稱 | 備注 |
控制節點 | 192.168.124.88 | controller | 最小4G,開啟虛擬化 |
計算節點 | 192.168.124.89 | computel | 最小2G,開啟虛擬化 |
[root@localhost ~]# setenforce 0 [root@localhost ~]# vi /etc/selinux/config [root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@localhost ~]# systemctl stop firewalld [root@localhost ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# hostnamectl set-hostname computer
[root@computer ~]# yum install -y chrony
[root@controller ~]# yum install -y chrony
controller修改時間同步服務器配置:
[root@controller ~]# vi /etc/chrony.conf
computer修改時間同步服務器配置:
[root@computer ~]# vi /etc/chrony.conf
兩個節點都重啟時間同步服務器
[root@controller ~]# systemctl restart chronyd
查看一下已經同步好了
[root@controller ~]# chronyc sources 210 Number of sources = 1 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^* 203.107.6.88 2 6 17 50 +2663us[+4287us] +/- 30ms [root@controller ~]# date Tue Feb 7 10:06:43 EST 2023
[root@controller ~]# vi /etc/hosts
[root@computer ~]# vi /etc/hosts
[root@controller ~]# yum install centos-release-openstack-train -y
[root@computer ~]# yum install centos-release-openstack-train -y
先安裝源
[root@controller ~]# yum install python-openstackclient -y
[root@computer ~]# yum install centos-release-openstack-train -y
繼續安裝
[root@controller ~]# yum install openstack-selinux -y
[root@computer ~]# yum install openstack-selinux -y
[root@controller ~]# yum install mariadb mariadb-server python2-PyMySQL -y
創建配置并修改IP
[root@controller ~]# vi /etc/my.cnf.d/openstack.cnf
[mysqld] bind-address = 192.168.124.88 default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8 ~
重啟數據庫
[root@controller ~]# systemctl enable mariadb.service[root@controller ~]# systemctl start mariadb.service
初始化數據庫
[root@controller ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] n ... skipping. By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
輸入密碼(這里輸入123密碼)
[root@controller ~]# yum install rabbitmq-server -y
重啟
[root@controller ~]# systemctl enable rabbitmq-server.service
[root@controller ~]# systemctl start rabbitmq-server.service
增加用戶
[root@controller ~]# rabbitmqctl add_user openstack 123Creating user "openstack"
開放權限
[root@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"Setting permissions for user "openstack" in vhost "/"
#下面引住的不需要做
(這里不需要做)查看消息隊列有的服務
[root@controller ~]# rabbitmq-plugins list
(這里不需要做)打開這兩個服務開啟圖像化界面
[root@controller ~]# rabbitmq-plugins enable rabbitmq_management rabbitmq_management_agent
(這里不需要做)查看端口
[root@controller ~]# ss -tln State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:25672 *:* LISTEN 0 128 192.168.124.88:3306 *:* LISTEN 0 128 *:4369 *:* LISTEN 0 128 *:22 *:* LISTEN 0 128 *:15672 *:* LISTEN 0 100 127.0.0.1:25 *:* LISTEN 0 128 :::5672 :::* LISTEN 0 128 :::22 :::* LISTEN 0 100 ::1:25 :::*
(這里不需要做)通過15672端口可以登錄消息隊列用戶:guest 密碼:guest
[root@controller ~]# yum install memcached python-memcached -y
[root@controller ~]# vi /etc/sysconfig/memcached
修改配置文件
PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="1024" OPTIONS="-l 127.0.0.1,::1,controller" ~
[root@controller ~]# systemctl enable memcached.service [root@controller ~]# systemctl start memcached.service
查看一下配置
[root@controller ~]# cat /etc/sysconfig/memcached PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="1024" OPTIONS="-l 127.0.0.1,::1,controller"
下面我們開始安裝部署組件,下一篇開始安裝Keystone
ldentity 身份認證
代號: Keystone
為OpenStack中其它服務提供身份驗證、服務注冊、服務令牌等功能。
