openstack M版安装 环境准备篇

4532423

环境准备：

• Controller Node: 1 processor, 2.5 GB memory, and 20 GB storage ，3 network interface
  
  
• Compute Node: 1 processor, 2 GB memory, and 20 GB storage，3 network interface
  
• Compute Node: 1 processor, 2 GB memory, and 20 GB storage，3 network interface
  
  
• Object Node: 1 processor, 512 GB memory, and 20 GB storage + 10 GB storage，2 network interface
  
  

controller 和compute节点三个网卡：一个是Management network （10.0.0.0/24），一个是Provider network(192.168.128.0/24)，一个是用来上网安装软件的。
object 节点不需要network网卡。


由于笔记本资源有限，内存分配的比较小。这里准备两个compute节点是为了测试热迁移。
该环境的网络我这里使用的是Self-service network。（linuxbridge + vlan）


一、环境准备

1、配置controller节点。
修改hostname：

1 2	[iyunv@controller ~]# cat /etc/hostname controller

配置网络：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

[iyunv@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=no NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=10.0.0.11 NETMASK=255.255.255.0 [iyunv@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 TYPE=Ethernet BOOTPROTO=none NAME=eth1 DEVICE=eth1 ONBOOT=yes [iyunv@controller ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2 TYPE=Ethernet BOOTPROTO=dhcp DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eth2 DEVICE=eth2 ONBOOT=yes

配置hosts解析

1 2 3 4 5 6 7

[iyunv@controller ~]# cat /etc/hosts 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.11   controller 10.0.0.31   compute1 10.0.0.21   compute2 10.0.0.41   block1

修改完成，重启服务器。
2、配置compute节点
修改hostname

1 2	[iyunv@compute1 ~]# cat /etc/hostname compute1

修改网卡

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

[iyunv@compute1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=static DEFROUTE=no NAME=eth0 DEVICE=eth0 ONBOOT=yes IPADDR=10.0.0.31 NETMASK=255.255.255.0 [iyunv@compute1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 TYPE=Ethernet BOOTPROTO=none NAME=eth1 DEVICE=eth1 ONBOOT=yes [iyunv@compute1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2 TYPE=Ethernet BOOTPROTO=dhcp DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eth2 DEVICE=eth2 ONBOOT=yes

配置hosts解析

1 2 3 4 5 6 7

[iyunv@compute1 ~]# cat /etc/hosts 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.11   controller 10.0.0.31   compute1 10.0.0.21   compute2 10.0.0.41   block1

重启服务器
.......
配置compute2(10.0.0.21)和object1(10.0.0.41)操作类似。
配置重启完服务器后确保各个节点能ping通外网和通过hostname  ping通各个节点。

3、安装时间服务器
安装控制节点

1	[iyunv@controller ~]# yum install chrony

编辑/etc/chrony.conf配置文件，可以不用改，只要添加allow 10.0.0.0/24

1 2 3 4 5 6 7 8 9

[iyunv@controller ~]# cat /etc/chrony.conf # Use public servers from the pool.ntp.org project. # Please consider joining the pool (http://www.pool.ntp.org/join.html). server 0.centos.pool.ntp.org iburst server 1.centos.pool.ntp.org iburst server 2.centos.pool.ntp.org iburst server 3.centos.pool.ntp.org iburst allow 10.0.0.0/24

启动服务，并添加到开机启动

1 2	[iyunv@controller ~]# systemctl enable chronyd.service [iyunv@controller ~]# systemctl start chronyd.service

安装compute节点

1	[iyunv@compute1 ~]# yum install chrony

编辑/etc/chrony.conf配置文件

1	server controller iburst

启动服务，并添加到开机启动

1 2	[iyunv@compute1 ~]# systemctl enable chronyd.service [iyunv@compute1 ~]# systemctl start chronyd.service

其他节点和compute节点一样。

验证，在控制节点执行下面命令。

1 2 3 4 5 6 7 8

[iyunv@controller ~]# chronyc sources 210 Number of sources = 4 MS Name/IP address         Stratum Poll Reach LastRx Last sample =============================================================================== ^* 202.118.1.130                 2   8   377   127   -361us[ -647us] +/- 7821us ^- time7.aliyun.com              2   8   177   128   +855us[ +570us] +/-   29ms ^- news.neu.edu.cn               2   8   377     6   -420us[ -420us] +/- 7927us ^- dns1.synet.edu.cn             2   8   200   17m  -3379us[-3251us] +/-   12ms

在其他节点执行下面命令

1 2 3 4 5

[iyunv@compute1 ~]# chronyc sources 210 Number of sources = 1 MS Name/IP address         Stratum Poll Reach LastRx Last sample =============================================================================== ^* controller                    3   6   377    22    +12us[  -18us] +/- 8716us

在name/ip address 栏显示的是controller

4、配置openstack 软件安装源，我这里用的是centos7

1 2	[iyunv@controller ~]# yum install centos-release-openstack-mitaka [iyunv@controller ~]# yum upgrade

在所有节点执行上面两步操作，重启服务器
安装openstack client

1 2	[iyunv@controller ~]# yum install python-openstackclient [iyunv@controller ~]# yum install openstack-selinux

5、安装配置数据库服务

1	[iyunv@controller ~]# yum install mariadb mariadb-server python2-PyMySQL

编辑/etc/my.cnf，增加下面配置。

1 2 3 4 5 6 7

[iyunv@controller ~]# cat /etc/my.cnf [mysqld] bind-address = 10.0.0.11 default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci character-set-server = utf8

启动服务，并加入开机启动

1 2	[iyunv@controller ~]# systemctl enable mariadb.service [iyunv@controller ~]# systemctl start mariadb.service

数据库安全设置，配置数据密码，其他全部yes

1	[iyunv@controller ~]# mysql_secure_installation

6、安装No sql数据库

1	[iyunv@controller ~]# yum install mongodb-server mongodb

修改配置文件/etc/mongod.conf

1 2	bind_ip = 10.0.0.11 smallfiles = true

启动服务，并加入开机启动

1 2	[iyunv@controller ~]# systemctl enable mongod.service [iyunv@controller ~]# systemctl start mongod.service

7、安装消息队列服务

1	[iyunv@controller ~]# yum install rabbitmq-server

启动服务，并加入开机启动

1 2	[iyunv@controller ~]# systemctl enable rabbitmq-server.service [iyunv@controller ~]# systemctl start rabbitmq-server.service

增加rabbitmq用户，并添加权限

1 2 3 4 5

[iyunv@controller ~]# rabbitmqctl add_user openstack RABBIT_PASS Creating user "openstack" ......done. [iyunv@controller ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*" Setting permissions for user "openstack" in vhost "/" ......done.

8、安装Memcached

1	[iyunv@controller ~]# yum install memcached python-memcached

启动服务，并加入开机启动

1 2	[iyunv@controller ~]# systemctl enable memcached.service [iyunv@controller ~]# systemctl start memcached.service

基础环境安装完成。
