openstack mitaka之二：搭建控制节点数据库和消息队列

1397535668

一：部署mariadb数据库
控制节点（192.168.11.103）：
yum install mariadb mariadb-server python2-PyMySQL -y
编辑：
/etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 控制节点管理网络ip（192.168.11.103）
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
#启服务：
systemctl enable mariadb.service
systemctl start mariadb.service#初始化数据库
#mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the currentpassword for the root user.  If you've just installed MariaDB, andyou haven't set the root password yet, the password will be blank,so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.Set root password? [Y/n] n
... skipping.By default, a MariaDB installation has an anonymous user, allowing anyoneto log into MariaDB without having to have a user account created forthem.  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] n
... skipping.
Normally, root should only be allowed to connect from 'localhost'.  Thisensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] n
... skipping.By default, MariaDB comes with a database named 'test' that anyone canaccess.  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 ensure that 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 MariaDBinstallation should now be secure.
Thanks for using MariaDB!

控制节点（192.168.11.103）：
yum install mongodb-server mongodb -y
编辑：/etc/mongod.conf
bind_ip = 控制节点管理网络ip（192.168.11.103）
smallfiles = true
启动服务：
systemctl enable mongod.service
systemctl start mongod.service三：部署消息队列rabbitmq
(验证方式:http://192.168.11.103:15672/ 用户:guest 密码:guest)
控制节点：
yum install rabbitmq-server -y
启动服务：
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
新建rabbitmq用户密码：
rabbitmqctl add_user openstack（用户名） liuyao(密码)
为新建的用户openstack设定权限：
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
六：部署memcached缓存（为keystone服务缓存tokens）
控制节点：
yum install memcached python-memcached -y
启动服务：
systemctl enable memcached.service
systemctl start memcached.service
