2.2.1两个节点都安装:

[root@linux-node1~]# yum install centos-release-openstack-newton –y

                                                                                                       <- openstack N版 仓库 ->

[root@linux-node1~]# yum install python-openstackclient –y    <- openstack客户端 ->

[root@linux-node1~]# yum install openstack-selinux –y  

<-如果没有关闭selinux安装这个包会自动设置selinux支持openstack ->

 

2.2.2在node1上安装:

[root@linux-node1 ~]# yum install mariadbmariadb-server python2-PyMySQL –y

<-安装数据库->

[root@linux-node1 ~]# vim/etc/my.cnf.d/openstack.cnf  <-编辑数据库配置文件->

[mysqld]

bind-address = 192.168.56.11              <-监听地址 ->

default-storage-engine = innodb             <-默认引擎 ->

innodb_file_per_table

max_connections = 4096                 <-最大连接数->

collation-server = utf8_general_ci           <-核对字符集 ->

character-set-server = utf8              <-字符集 ->

[root@linux-node1 ~]# yum installrabbitmq-server    <-安装rabbitMQ消息队列->

[root@linux-node1 ~]#  yum install memcached python-memcached <-安装缓存 ->

[root@linux-node1 ~]# yum installopenstack-keystone httpd mod_wsgi –y

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDEDFOR ALL MariaDB

     SERVERS IN PRODUCTION USE!  PLEASEREAD 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, thepassword will be blank,

so you should just press enter here.

 

Enter current password for root (enter fornone):

OK, successfully used password, moving on...

 

Setting the root password ensures thatnobody 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 ananonymous user, allowing anyone

to log into MariaDB without having to have auser 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 toconnect from 'localhost'.  This

ensures that someone cannot guess at theroot password from the network.

 

Disallow root login remotely? [Y/n] y

 ...Success!

 

By default, MariaDB comes with a databasenamed '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 ensurethat 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!

 

2.2配置rabbitMQ消息队列

[root@linux-node1 ~]# systemctl enablerabbitmq-server.service

[root@linux-node1 ~]# systemctl startrabbitmq-server.service  <-启动 ->

[root@linux-node1 ~]# rabbitmqctl add_useropenstack openstack  <-添加用户 ->

Creating user "openstack" ...

[root@linux-node1 ~]# rabbitmqctlset_permissions openstack ".*" ".*" ".*"

Setting permissions for user"openstack" in vhost "/" ...     <-设置权限->

[root@linux-node1 ~]# rabbitmq-pluginsenable rabbitmq_management <-重启 ->

The following plugins have been enabled:

 mochiweb

 webmachine

 rabbitmq_web_dispatch

 amqp_client

 rabbitmq_management_agent

 rabbitmq_management

 

Applying plugin configuration torabbit@linux-node1... started 6 plugins.
