一、安装并使用MariaDB作为Ambari、Hive、Hue的存储数据库。
yum install mariadb-server mariadb
启动、查看状态,检查mariadb是否成功安装
systemctl start mariadb systemctl status mariadb
二、配置mariadb
1,首先停止MariaDb 服务的运行
systemctl stop mariadb
2,编辑/etc/my.cnf 在[mysqld]段下,添加如下几行行配置:
transaction-isolation = READ-COMMITTED max_connections = 550 innodb_flush_method = O_DIRECT
保存退出后,配置mariadb服务开机启动,并重新启动MariaDB
systemctl enable mariadb systemctl start mariadb
3,运行mariadb安全配置脚本/usr/bin/mysql_secure_installation ,[email protected],密码这里设为hadoop
/usr/bin/mysql_secure_installation
****授权用户root使用密码passwd从任意主机连接*到mysql服务器
mysql -uroot -p use mysql; GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘****‘ WITH GRANT OPTION; flush privileges;
**** 安装MySQL JDBC Driver 连接 MariaDB
**** 下载、解压缩,复制mysql-connector-java-5.1.46-bin.jar到/usr/share/java/,并重命名:
wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz tar zxvf mysql-connector-java-5.1.46.tar.gz cd mysql-connector-java-5.1.46/ cp mysql-connector-java-5.1.46-bin.jar /usr/share/java/mysql-connector-java.jar
