OpenStackrocky版安装步骤参考官网步骤

1、OpenStackrocky 版安装步骤，参考官步骤Centos建议最低配置：控制节点：1个处理器，4 GB内存和5 GB存储计算节点：1个处理器，2 GB内存和10 GB存储，环境准备：以下区分数据库密码和openstack户密码，可替换密码 描述RABBIT_PASS RabbitMQ户openstack的密码123456 数据库root的密码KEYSTONE_DBPASS keystone的数据库密码GLANCE_DBPASS glance的数据库密码NOVA_DBPASS nova的数据库密码PLACEMENT_DBPASS placement的数据库密码NEUTRON_DBPASS

2、neutron的数据库密码DASH_DBPASS DASH的数据库密码CINDER_DBPASS cinder的数据库密码ADMIN_PASS admin户密码myuser_PASS myuser户密码GLANCE_PASS glance户的密码NOVA_PASS nova户的密码PLACEMENT_PASS placement户的密码NEUTRON_PASS neutron户的密码METADATA_SECRET 元数据代理的密码CINDER_PASS cinder户的密码1.1络环境1.1.1控制节点配置第个接作为管理接：IP地址：1络掩码：默认关：提供程序接使特殊配置，但未分配IP地址。将

3、第个接配置为提供程序接：替换INTERFACE_NAME为实际的接名称。例如， eth1或ens224。vi /etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAMEDEVICE=INTERFACE_NAMETYPE=EthernetONBOOT=“yes”BOOTPROTO=“none”将控制节点的主机名设置为controller。hostnamectlset-hostname controllervi /etc/hosts 件增加以下内容：#controller1 controller#compute1 compute#block1 block

4、11.1.2计算节点配置第个接作为管理接：IP地址：1络掩码：默认关：提供程序接使特殊配置，但未分配IP地址。将第个接配置为提供程序接：替换INTERFACE_NAME为实际的接名称。例如， eth1vi /etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAMETYPE=EthernetNAME=INTERFACE_NAMEDEVICE=INTERFACE_NAMEONBOOT=yesBOOTPROTO=noneIPADDR=1PREFIX=24GATEWAY=将计算节点的主机名设置为compute。 hostnamectl set-hostnam

5、e computevi /etc/hosts 件增加以下内容：#controller1 controller#compute1 compute#block1 block1.1.3块存储节点（可选）如果要部署块存储服务，请配置个额外的存储节点配置IP地址IP地址： 1络掩码:默认关： 同上编辑/etc/hosts件1.2 NTP络时间协议1.2.1控制节点安装chrony服务yum -y install chrony编辑修改配置件，替换NTP_SERVER为合适的更准确NTP服务器的主机名或IP地址（）（）vi /etc/chrony.confserver NTP_SERVER iburstal

6、low /24配置开机动运chrony，并重启服务systemctl enable chronyd.servicesystemctl start chronyd.service1.2.2其他节点yum -y install chrony修改配置件vi /etc/chronyserver controller iburst注释掉pooloffline iburst配置开机动运chrony，并重启服务systemctl enable chronyd.servicesystemctl start chronyd.service1.2.3验证在控制节点上运此命令：chronyc sources210

7、Number of sources = 1MS Name/IP address Stratum Poll Reach LastRx Last sample* 2 6 177 46 +17us -23us +/- 68ms在所有其他节点上运相同的命令：chronyc sources210 Number of sources = 1MS Name/IP address Stratum Poll Reach LastRx Last sample* controller 3 9 377 421 +15us -87us +/- 15msCentOS extras默认包含存储库，因此只需安装软件包即可启O

8、penStack存储库yum -y install centos-release-openstack-rocky升级所有节点上的包：yum -y upgrade安装OpenStack客户端：yum -y install python-openstackclientCentOS SELinux。安装openstack-selinuxOpenStackselinuxfirewalld）yum -y install openstack-selinux笔者这没有安装openstack-selinux，直接关闭了所有节点的selinux和firewalld#systemctl disable firew

9、alldvim /etc/sysconfig/selinuxeSELINUX=disabled建议重启所有节点以适以上配置#reboot1.4安装SQL数据库（控制节点）yum -y install mariadb mariadb-server python2-PyMySQL创建和编辑/etc/f.d/f （这个件本不存在）vi /etc/f.d/fmysqldbind-address = 1 (控制节点ip)default-storage-engine = innodbinnodb_file_per_table = onmax_connections = 4096collation-serv

10、er = utf8_general_cicharacter-set-server = utf8启动数据库服务并配置开机启动systemctl enable mariadb.servicesystemctl start mariadb.service运mysql_secure_installation 脚本来保护数据库服务mysql_secure_installation也可以输以下命令动配置数据库密码为123456echo -e “nYn123456n123456nYnnnYnYn” | mysql_secure_installation1.5消息队列（控制节点）yum -y install

11、rabbitmq-server启动消息队列服务并将其配置为开机启动：systemctl enable rabbitmq-server.servicesystemctl start rabbitmq-server.service1.6 memcached 缓存yum -y install memcached python-memcached修改配置件（更改现有 OPTIONS=-l ,:1）vi /etc/sysconfig/memcachedOPTIONS=-l ,:1,controller启动Memcached服务并将其配置为开机启动：systemctl enable memcached.s

12、ervicesystemctl start memcached.service，安装openstack服务1，keystone 认证服务（控制节点）1.1在安装和配置keystone之前，必须先创建keystone数据库mysql-u root -pMariaDB (none) CREATE DATABASE keystone;对keystone数据库配置的适当访问权限（替换KEYSTONE_DBPASS为合适的密码）MariaDB (none) GRANT ALL PRIVILEGES ON keystone.* TO keystonelocalhost IDENTIFIED BYKEYST

13、ONE_DBPASS;MariaDB (none) GRANT ALL PRIVILEGES ON keystone.* TO keystone% IDENTIFIED BYKEYSTONE_DBPASS;退出数据库访问客户端exit安装软件包yum -y install openstack-keystone httpd mod_wsgi修改keystone配置件（替换KEYSTONE_DBPASS为合适的密码）vi /etc/keystone/keystone.confdatabaseconnection = mysql+pymysql:/keystone:KEYSTONE_DBPASSco

14、ntroller/keystone#注释掉或删除connection该database部分中的任何其他选项tokenprovider = fernet填充数据库：su -s /bin/sh -c “keystone-manage db_sync” keystone建议进keystone数据库查看是否成功成表初始化Fernet密钥存储库：keystone-manage fernet_setup -keystone-user keystone -keystone-group keystonekeystone-manage credential_setup -keystone-user keysto

15、ne -keystone-group keystone1.2配置Apache HTTP服务器（控制节点）vi /etc/httpd/conf/httpd.confServerName controller:80创建/usr/share/keystone/wsgi-keystone.conf件的链接：ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/启动Apache HTTP服务并将其配置为开机启动：systemctl enable httpd.servicesystemctl start httpd.service1.

16、3创建openstack域，项，（控制节点）（虽然之前引导时keystone-manage bootstrap步骤中已存在“默认”域，但创建新域的正式法是）（#openstack domain create -description “An Example Domain” example ）创建service 项：openstack project create -domain default -description “Service Project” service-+| Field | Value |-+| description | Service Project | domain_i
