# 1.安装Mariadb数据库来存储信息 #

# 2.NoSQL数据库服务 #

# 3.安装并配置(RabbitMQ)消息队列服务器 #

# 4.安装Memcached缓存服务 #

## 1.安装Mariadb数据库来存储信息 ##

\# yum -y install mariadb mariadb-server python2-PyMySQL \#编辑配置文件

#vi /etc/my.cnf
    在[mysqld]下添加如下内容
    bind-address = 192.168.100.10
    default-storage-engine = innodb
    innodb_file_per_table
    max_connections = 4096
    collation-server = utf8_general_ci
    character-set-server = utf8

启动数据库并设置开机自启

#systemctl start mariadb
    #systemctl enable mariadb

### 运行`mysql_secure_installation`脚本,为root用户设置密码 ###

[root@controller ~]# mysql_secure_installation 
    
    Enter current password for root (enter for none):   #这句话直接回车
    
    Set root password? [Y/n]       选择Y，然后设置数据库密码  这里设置000000
    
    Remove anonymous users? [Y/n]     选择Y
    
    Disallow root login remotely? [Y/n]    选择N
    
    Remove test database and access to it? [Y/n]    选择Y
    
    Reload privilege tables now? [Y/n]    选择Y

### 登录数据库验证 ###

[root@controller ~]# mysql -uroot -p000000

## 2.NoSQL数据库服务 ##

### 安装NoSQL ###

#yum -y install mongodb-server mongodb
    
    编辑配置文件
    #vi /etc/mongod.conf
    修改bind_ip = 192.168.100.10     #bind_ip 使用控制节点管理网卡的IP地址
    修改smallfiles = true

保存退出

### 启动并设置开机启动MongoDB ###

#systemctl start mongod
    #systemctl enable mongod

## 3.安装并配置(RabbitMQ)消息队列服务器 ##

#### 安装RabbitMQ服务 ####

#yum -y install rabbitmq-server 
    
    启动并设置开机启动
    #systemctl start rabbitmq-server
    #systemctl enable rabbitmq-server
    
    添加Openstack用户并设置密码
    #rabbitmqctl add_user openstack 000000    #此处六个零为密码，可自行更改
    
    给openstack用户权限 ： 配置 写  读  三个权限
    [root@controller ~]# rabbitmqctl set_permissions openstack '.*' '.*' '.*'
