3.1 安装MariaDB数据库

# master

# yum install mariadb mariadb-server mysql-connector-java 启动服务

# systemctl enable mariadb

# systemctl start mariadb 配置MySQL

#mysql_secure_installation

按enter确认后设置数据库root密码，我们这里设置为“bigdata” Remove anonymous users [Y/n] y Disallow root login remotely [Y/n] n

Remove test database and access to it [Y/n] y Reload privilege tables now [Y/n] y 创建ambari数据库 # mysql -uroot -pbigdata

MariaDB [(none)]> create database ambari;

MariaDB [(none)]> grant all privileges on ambari.* to 'ambari'@'localhost' identified by 'bigdata';

MariaDB [(none)]> grant all privileges on ambari.* to 'ambari'@'%' identified by 'bigdata';

MariaDB [(none)]> use ambari;

MariaDB [ambari]> source /var/lib/ambari-server/resources/ MariaDB [ambari]> Bye
