openstack Mitaka实验环境安装(centos系统)

时间：2022-12-05 08:56:13

本博文仅供参考，具体一定详细学习官方安装文档。

一、 准备工作

博主采用的物理服务器是PowerEdge R420，服务器安装centos 64位系统（安装方法自行百度）。本次只是为了学习openstack安装过程所以采用all in one方式部署，下次正式搭建实验环境的时候会采用两台服务器搭建。由于采用all in one部署的方式，不需要关心管理网还是外网啥的，所以安装起来要简单不少。例外由于国外的源访问比较慢，这里将源替换为阿里云的源

第一步：备份你的原镜像文件，以免出错后可以恢复。

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

第二步：下载新的CentOS-Base.repo 到/etc/yum.repos.d/

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

第三步：运行yum makecache生成缓存

yum clean all

yum update

二、安装过程

1、 安装NTP服务

（all in one的方式其实这一步可以省略，为了学习这里也安装了一把 ）

# yum install chrony

修改/etc/chrony.conf写入

server 202.108.6.95 iburst

allow 10.0.0.0/24 （其他节点所在网段）

http://ntp.org.cn/ 上面有可用的NTP服务器 IP供选择，10.0.0.0/24为其他节点所在网段也就是内部网段。

# systemctl enable chronyd.service

# systemctl start chronyd.service

# chronyc sources

安装完成后可以看到:

openstack Mitaka实验环境安装(centos系统)

NTP服务 在all in one方式时到此就安装完了，对于多台服务器就需要在其他节点安装了，并且把NTP IP改成controller即可。

2、 安装openstack包

这一步需要在所有服务器上面安装。

    # yum install centos-release-openstack-mitaka

    # yum upgrade

    # reboot （如果升级了内核可能需要重启系统）

    # yum install python-openstackclient

    # yum install openstack-selinux （这个如果不安装，后面apache起不来）

3、 SQL数据库安装

  # yum install mariadb mariadb-server python2-PyMySQL （有几个包下载很慢，需要耐心等待）

修改/etc/my.cnf.d/openstack.cnf或者增加下面的内容

    [mysqld]

    bind-address = 0.0.0.0

    default-storage-engine = innodb

    innodb_file_per_table

    max_connections = 4096

    collation-server = utf8_general_ci

    character-set-server = utf8

启动服务，添加开机启动

# systemctl enable mariadb.service

# systemctl start mariadb.service

安装数据库

# mysql_secure_installation（此处按照提示操作即可，需要设置root密码）

由于需要设置的密码比较多，如果是实验环境强烈建议大家都用一样的，这样就不会搞混掉和忘记。

4、 安装消息队列 （message queue）

# yum install rabbitmq-server （下载依赖包很慢。可能会超时）

# systemctl enable rabbitmq-server.service

# systemctl start rabbitmq-server.service

# rabbitmqctl add_user openstack RABBIT_PASS

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

RABBIT_PASS设置成你的密码

5、 Memcached安装

# yum install memcached python-memcached

# systemctl enable memcached.service

# systemctl start memcached.service

到这一步为止，准备工作完成，下面开始安装具体服务了。

6、 Identity 安装

创建keystone数据库

$ mysql -uroot -ppassword

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \

      IDENTIFIED BY 'KEYSTONE_DBPASS';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \

      IDENTIFIED BY 'KEYSTONE_DBPASS';

生成管理员token，记得保存下来，后面要用到。

$ openssl rand -hex 10

安装keystone包

# yum install openstack-keystone httpd mod_wsgi

配置/etc/keystone/keystone.conf

openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token ADMIN_TOKEN

openstack-config --set /etc/keystone/keystone.conf database admin_token connection mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

openstack-config --set /etc/keystone/keystone.conf token provider fernet

更新keystone数据库

su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化Fernet keys

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

配置apache

vim /etc/httpd/conf/httpd.conf

ServerName controller

修改 /etc/httpd/conf.d/wsgi-keystone.conf

Listen 5000

Listen 35357

<VirtualHost *:5000>

    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

    WSGIProcessGroup keystone-public

    WSGIScriptAlias / /usr/bin/keystone-wsgi-public

    WSGIApplicationGroup %{GLOBAL}

    WSGIPassAuthorization On

    ErrorLogFormat "%{cu}t %M"

    ErrorLog /var/log/httpd/keystone-error.log

    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>

        Require all granted

    </Directory>

</VirtualHost>

<VirtualHost *:35357>

    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

    WSGIProcessGroup keystone-admin

    WSGIScriptAlias / /usr/bin/keystone-wsgi-admin

    WSGIApplicationGroup %{GLOBAL}

    WSGIPassAuthorization On

    ErrorLogFormat "%{cu}t %M"

    ErrorLog /var/log/httpd/keystone-error.log

    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>

        Require all granted

    </Directory>

</VirtualHost>

启动服务和加入开机启动

# systemctl enable httpd.service

# systemctl start httpd.service

创建服务实体和API endpoint

$ export OS_TOKEN=184290ef5b56fcb9afc8

$ export OS_URL=http://127.0.0.1:35357/v3

$ export OS_IDENTITY_API_VERSION=3

下面的步骤如果出错，可以使用openstack service list 显示所有的服务，在利用ID和openstack service delete删除之前创建的service entity，并且到keystone数据库中删除相应的endpoint记录即可重新操作

$openstack service create \

        --name keystone --description "OpenStack Identity" identity

$ openstack endpoint create --region RegionOne \

        identity public http://127.0.0.1:5000/v3

$ openstack endpoint create --region RegionOne \

        identity internal http://127.0.0.1:5000/v3

$ openstack endpoint create --region RegionOne \

        identity admin http://127.0.0.1:35357/v3

创建缺省 domain,admin project

$ openstack domain create --description "Default Domain" default

$ openstack project create --domain default --description "Admin Project" admin

$ openstack user create --domain default --password-prompt admin (需要输入密码)

$ openstack role create admin

$ openstack role add --project admin --user admin admin

创建 demo

$ openstack project create --domain default --description "Service Project" service

$ openstack project create --domain default --description "Demo Project" demo

$ openstack user create --domain default --password-prompt demo (需要输入密码)

$ openstack role create user

$ openstack role add --project demo --user demo user

编辑/etc/keystone/keystone-paste.ini

将 admin_token_auth 从[pipeline:public_api], [pipeline:admin_api]和 [pipeline:api_v3] 移除。

$ unset OS_TOKEN OS_URL

$ openstack --os-auth-url http://contorller:35357/v3 \

    --os-project-domain-name default --os-user-domain-name default \

    --os-project-name admin --os-username admin token issue

$ openstack --os-auth-url http://contorller:5000/v3 \

    --os-project-domain-name default --os-user-domain-name default \

    --os-project-name demo --os-username demo token issue

openstack --os-auth-url http://controller:5000/v3 \

    --os-project-domain-name default --os-user-domain-name default \

    --os-project-name demo --os-username demo token issue

创建 admin-openrc文件写入下面的内容，免去后续频繁操作。后面安装其他服务要用到这个脚本。

export OS_PROJECT_DOMAIN_NAME=default

export OS_USER_DOMAIN_NAME=default

export OS_PROJECT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=ADMIN_PASS

export OS_AUTH_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3

export OS_IMAGE_API_VERSION=2

创建好需要加入执行权限

chmod +x admin-openrc

$ . admin-openrc

$ openstack token issue

keystone服务安装完毕下面安装image服务

7、 image服务安装（glance）

同keystone服务，第一步创建数据库

$ mysql -uroot -ppassword

CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \

        IDENTIFIED BY 'GLANCE_DBPASS';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \

        IDENTIFIED BY 'GLANCE_DBPASS';

添加到admin

$ . admin-openrc

$ openstack user create --domain default --password-prompt glance

$ openstack role add --project service --user glance admin

$ openstack service create --name glance --description "OpenStack Image" image

$ openstack endpoint create --region RegionOne image public http://controller:9292

同在控制节点的安装网络配置，将前面的操作再次重新执行一边。

配置计算服务使用网络，配置/etc/nova/nova.conf

openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696

openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:35357

openstack-config --set /etc/nova/nova.conf neutron auth_type password

openstack-config --set /etc/nova/nova.conf neutron project_domain_name default

openstack-config --set /etc/nova/nova.conf neutron user_domain_name default

openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne

openstack-config --set /etc/nova/nova.conf neutron project_name service

openstack-config --set /etc/nova/nova.conf neutron username neutron

openstack-config --set /etc/nova/nova.conf neutron password NEUTRON_PASS

# systemctl restart openstack-nova-compute.service

# systemctl enable neutron-linuxbridge-agent.service

# systemctl start neutron-linuxbridge-agent.service

验证安装服务

在控制节点执行：

$ . admin-openrc

$ neutron ext-list

至此主要模块安装完毕。
