bind-address = 192.168.56.11              <-監(jiān)聽地址 ->

default-storage-engine = innodb             <-默認引擎 ->

innodb_file_per_table

max_connections = 4096                 <-最大連接數(shù)->

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

[root@linux-node1 ~]# yum installrabbitmq-server    <-安裝rabbitMQ消息隊列->

[root@linux-node1 ~]#  yum install memcached python-memcached <-安裝緩存 ->

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

三．數(shù)據(jù)庫環(huán)境及消息隊列環(huán)境配置

2.1數(shù)據(jù)庫配置

[root@linux-node1 ~]# cat/etc/my.cnf.d/openstack.cnf   <-準備環(huán)境時配置的 ->

[mysqld]

bind-address = 192.168.56.11

 

default-storage-engine = innodb

innodb_file_per_table

max_connections = 4096

collation-server = utf8_general_ci

character-set-server = utf8

[root@linux-node1 ~]# systemctl enablemariadb.service   <-允許數(shù)據(jù)庫啟動 ->

[root@linux-node1 ~]# systemctl startmariadb.service   <-啟動數(shù)據(jù)庫 ->

[root@linux-node1 ~]#mysql_secure_installation      <-設(shè)置密碼并配置 ->

 

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消息隊列

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

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

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

Creating user "openstack" ...

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

Setting permissions for user"openstack" in vhost "/" ...     <-設(shè)置權(quán)限->

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

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.
