数据库安装
控制节点：
yum install mariadb mariadb-server python2-PyMySQL -y #安装

vi /etc/my.cnf.d/openstack.cnf #配置    在[mysqld]中，设置“bind-address”值为控制节点的管理网络IP地址以是的其他节点可以通过管理网络访问访问数据库。设置其他关键字来设置一些有用的选项和UTF-8编码：

[mysqld]

bind-address = 10.0.0.11

default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

启动数据库服务，并将其配置为开机自启：

systemctl start mariadb
systemctl enable mariadb #启动

mysql_secure_installation #安全初始化 笔记待完善
回车 #当前密码
n #设置root密码吗？
y #移除匿名用户
y #禁止root远程登陆
y #删除test库和访问权限
y #重载权限表

[root@controller ~]# netstat -lntup|grep 3306
tcp 0 0 10.0.0.11:3306 0.0.0.0:* LISTEN 23304/mysqld #验证
