CENTOS7 安装openstack mitaka版本(最新整理完整版附详细截图和操作步骤,添加了cinder和vxlan,附上个节点的配置文件)
实验环境准备:
为了更好的实现分布式mitaka版本的效果。我才有的是VMware的workstations来安装三台虚拟机,分别来模拟openstack的controller节点 compute节点和cinder节点。(我的宿主机配置为 500g 硬盘 16g内存,i5cpu。强烈建议由条件的朋友将内存配置大一点,因为我之前分配的2g太卡。)
注意:要实验kvm虚拟机,在vmware里面启动虚拟机之前开启cpu虚拟化可以在开机之后输入:
egrep -c '(vmx|svm)' /proc/cpuinfo
查看。Vmwar如何开启:
具体配置开始:
Controller节点: 2cpu +4gram+50gdisk+2nic(192.168.1.182(桥接)+192.168.8.183(nat))
compute节点: 2cpu +4gram+50gdisk+2nic(192.168.1.183(桥接)+192.168.8.183(nat))
cinder节点: 1cpu +1gram+10gdisk+20gdisk(次硬盘为安装完成之后添加,不要岁系统添加到lvm,如果手动分区就可以随虚拟机一起安装,安装cinder的磁盘,一点要干净的磁盘,要不然会报错(楼主在这个问题上面哭了半天才发现))+2nic(192.168.1.184(桥接)+192.168.8.184(nat))
现在正是开始:
一. 所有节点都要安装和配置的基础环境
系统安装完成之后,所有节点关掉防火墙,关掉selinux,设置好root密码
systemctl stop firewalld.service
vi /etc/sysconfig/selinux 将enforce改成disabled
设置好root密码:我的root密码统一设置为adm*123,为了方便和不出差错,我将以后的数据库的密码和keystone ,glance,rabbitmq,nova,cinder的密码都设置为adm*123
所有节点添加主机名解析:/etc/hosts
设置主机名:
Controller节点:hostnamectl set-hostname controller
Compute 节点:hostnamectl set-hostname compute
Cinder 节点:hostnamectlset-hostname cinder
3. 登录到每个节点将主机名添加解析:
vi /etc/hosts加入:
添加时间同步:
在controller节点:yum install chrony –y
4. 配置时间同步:
vi /etc/chrony.conf加入:
server time.windows.com iburst
设置开机启动以及启动chronyd
systemctl enable chronyd.service
systemctl start chronyd.service
在compute和cinder节点:
yum install chrony -y
vi /etc/chrony.conf加入:
server controller iburst
设置开机启动以及启动chronyd:
systemctl enable chronyd.service
systemctl start chronyd.service
5.配置openstack mitaka的yum源和安装基础软件包(所有节点都需要)
安装yum源:
yum install centos-release-openstack-mitaka -y
在主机上更新软件包和内核:
yum upgrade
安装OpenStackclient:
yum install python-openstackclient -y
如果你开起了selinux可以安装openstack-selinux,如果关掉了就不要安装。我们这里选择不安装。如果需要在安装直接运行:
yum install openstack-selinux
二.我的计划是在controller节点上面安装mysql,rabbitmq,keystone,glance,nova-api等
1. 下面安装mysql(记住在controller节点上面):
安装mysql:
yum install mariadb mariadb-server python2-PyMySQL -y
配置:
vi/etc/my.cnf 加入:
bind-address= 192.168.1.182
default-storage-engine= innodb
innodb_file_per_table
max_connections= 4096
collation-server= utf8_general_ci
character-set-server= utf8
配置开机启动和启动mysql:
systemctl enable mariadb.service
systemctl start mariadb.service
设置密码:
mysql_secure_installation
按照操作一步一步完成即可,都是傻瓜式的操作,我的设置为amd*123
2 .安装rabbitmq(个个服务之间的节点的通讯服务)
安装软件:
yum install rabbitmq-server
启动服务:
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
创建rabbitmq用户openstack并设置密码为adm*123
rabbitmqctl add_user openstack adm*123
给刚刚创建的openstack用户授权:
rabbitmqctl set_permissions openstack ".*"".*"".*"
安装memcache
安装:
yum install memcached python-memcached
启动服务:
systemctl enable memcached.service
systemctl start memcached.service
4 安装keystone(认证服务)
创建keystone的数据库:
登录数据库:mysql –uroot –padm*123然后执行:
CREATE DATABASE keystone;
授权keystone用户:
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'adm*123';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'adm*123';
生成admin的token的随机码:
openssl rand -hex 10
copy下来这个值,到时候会配置keystone的配置文件里面。
安装keystone的相关软件:
yum install openstack-keystone httpd mod_wsgi -y
修改配置文件:
[DEFAULT]
...
admin_token = 刚刚生成的随机数
数据库连接:
[database]
...
connection = mysql+pymysql://keystone:adm*123@controller/keystone
打开token:
[token]
...
provider = fernet
保存退出之后,同步数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone
初始化fernet key:
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
配置httpd服务:
vi/etc/httpd/conf/httpd.conf
修改ServerName
ServerName controller
在/etc/httpd/conf.d/下增加 wsgi的conf文件:
vi/etc/httpd/conf.d/wsgi-keystone.conf 加入下面内容:
Listen5000
Listen35357
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}
WSGIPassAuthorizationOn
ErrorLogFormat"%{cu}t %M"
ErrorLog/var/log/httpd/keystone-error.log
CustomLog/var/log/httpd/keystone-access.log combined
Requireall granted
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}
WSGIPassAuthorizationOn
ErrorLogFormat"%{cu}t %M"
ErrorLog/var/log/httpd/keystone-error.log
CustomLog/var/log/httpd/keystone-access.log combined
Requireall granted
保存退出。
启动httpd服务:
systemctl enable httpd.service
systemctl start httpd.service
1 创建service和endpoint:
配置授权的token
exportOS_TOKEN=生成的随机数
配置endpoint的url:
exportOS_URL=http://controller:35357/v3
配置api的版本:
exportOS_IDENTITY_API_VERSION=3
创建认证服务:
openstack service create \
--name keystone --description "OpenStack Identity" identity
创建认证服务器的api 的endpoint:
openstack endpoint create --region RegionOne \
identity public http://controller:5000/v3
openstack endpoint create --region RegionOne \
identity internal http://controller:5000/v3
openstack endpoint create --region RegionOne \
identity admin http://controller:35357/v3
创建域,项目,用户,角色:
创建default域:
openstack domain create --description "Default Domain" default
创建admin项目:
openstack project create --domain default \
--description "Admin Project" admin
创建admin用户:
openstack user create --domain default \
--password-prompt admin
提示输入密码,我们都输入adm*123
创建admin的角色:
openstack role create admin
将admin用户添加到admin这个角色和项目里面:
openstack role add --project admin --user admin admin
确认操作:
如果出现以下结果,代表上面的操作没有问题,如果有问题,请返回检查:
取消环境变量;
unset OS_TOKEN OS_URL
执行:admin user,如果有返回这个成功:
openstack --os-auth-url http://controller:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue
如果adm*123 ,看返回结果
我的返回结果:
创建admin 管理用户和demo普通用户的环境脚本:
我的admin脚本内容:
我的demo脚本内容:
直接执行
. admin-openrc
然后运行:
openstack token issue
就可以反正相同结果。
三. 安装glance(镜像服务)
登录数据库创建glance数据库:
mysql -u root –padm*123
创建glance数据库:
CREATE DATABASE glance;
授权:
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY 'adm*123';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY 'adm*123';
退出mysql端。
创建glance的用户,加入到admin组,创建p_w_picpath服务,创建endpoint。
. admin-openrc
创建用户和添加角色:
openstack user create --domain default --password-prompt glance
密码:adm*123
添加角色:
openstack role add --project service --user glance admin
创建服务:
openstack service create --name glance \
--description "OpenStack Image" p_w_picpath
创建endpoint:
openstack endpoint create --region RegionOne \
p_w_picpath public http://controller:9292
openstack endpoint create --region RegionOne \
p_w_picpath internal http://controller:9292
openstack endpoint create --region RegionOne \

这个时候可以通过网络访问openstack了。
注意:现在只是可以通过openstack访问虚拟机了,但是不能安装虚拟机,没有安装cinder,所以我们接下来安装cinder。
九 安装cinder(存储)
在controller节点上执行如下操作:
创建cinder数据库,并授权:
mysql -u root –padm*123
创建数据库:
CREATE DATABASE cinder;
授权:
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
IDENTIFIED BY 'adm*123';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
IDENTIFIED BY 'adm*123';
创建用户,角色,服务,endpoint:
. admin-openrc
用户密码为adm*123:
openstack user create --domain default --password-prompt cinder
openstack role add --project service --user cinder admin
openstack service create --name cinder \
--description "OpenStack Block Storage" volume
openstack service create --name cinderv2 \

systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
创建pv和vg组,这个时候就要用到我们添加的那个干净的磁盘了,可以使用fdisk –l 查看,我这儿使用的sdc(一定要干净的磁盘,我在这里爬坑的时候你们一定在笑)
pvcreate /dev/sdc
创建组:
vgcreate cinder-volumes /dev/sdc
配置lvm的权限:
配置/etc/lvm/lvm.conf,添加
找到devices组添加:
说明:我的是sda,sdb,全部都是lvm卷,所以要全部添加
filter= [ "a/sda/", "a/sdb/","a/sdc/","r/.*/"]
安装软件:
yum install openstack-cinder targetcli python-keystone -y
配置/etc/cinder/cinder.conf
[database]
...
connection = mysql+pymysql://cinder:adm*123@controller/cinder
[DEFAULT]
...
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 192.168.1.184
enabled_backends = lvm
在文档末尾加入:
[lvm]
...
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
[oslo_concurrency]
...
lock_path = /var/lib/cinder/tmp
启动服务:
systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
确认操作:
在controller节点:
. admin-openrc
cinder service-list
看输出结果
我的结果为:
到现在为止,我们可以创建虚拟机。
再次之前我们需要创建vxlan。
步骤如下:
创建provider网络:
neutron--debug net-create --shared provider --router:external True--provider:network_type flat --provider:physical_network provider
创建子网,floatip使用:
neutronsubnet-create provider 192.168.1.0/24 --name public-sub --allocation-poolstart=192.168.1.210,end=192.168.1.220 --dns-nameserver 61.139.2.69 --gateway192.168.1.1
创建vxlan私网:
neutronnet-create private --provider:network_type vxlan --router:external False--shared
创建子网:
neutron subnet-create private --nameinternal-subnet --gateway 192.168.13.1 192.168.13.0/24
由于我做这个时候没有截图,所以截图使用来自网上,请谅解:
创建了网络之后创建路由,虚拟机才可以通网。
在dashboard里面点击项目—网络—路由—新建路由即可。
到此你可以上传你制作好的镜像,创建你的虚拟机了(镜像可以在晚上去下载,也可以自己制作,网上的大神多得很 哈哈)。
最后总结一下自己遇到的问题:
在cinder的时候遇到这种错误(所以服务正常):
2016-10-2712:53:33.077 76504 ERROR cinder.scheduler.flows.create_volume[req-1d9179f3-913c-4e72-a357-437ed4ed3c2d 3da30194de374868990d83f474149ae663ed5b1babb74b3080f90a365efbcb84 - - -] Failed to run taskcinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: Novalid host was found. No weighed hosts available
最后是新加一个干净的磁盘,重新配置解决。
在nova和neutron的时候,出现401的授权错误
查看日志
查看配置文件
删除用户,重新建立
我的属于第三种,没有任何问题,就是删除之后,重新建立解决。
3 在安装虚拟的时候不要使用iso文件去安装,一定要自己制作的镜像(不知道的可以网上找,多得你数不清),我使用centos7dvd版本的iso安装文件去安装,始终没有办法进入系统,安装完成之后重启还是进入安装界面。
附上我的dashboard的几个截图:
最后附上所有节点的配置文件。如有错误请指正交了 [email protected].
