HDP卸载

HDP卸载

删除组件

1. 在ambari ui中将服务关闭

2. 删除service组件，ambari必须保留一个组件，所以留个zookeeper不删即可

3. 在各节点中将ambari服务停止：

   ambari-agent stop
   
   ambari-server stop
   

卸载ambari相关组件

yum remove -y ambari*

yum remove -y smartsense-hst

卸载hdp相关组件

#这个会删除很多hdp依赖的包比如hadoop、hive、spark、tez、livy等，不过有些包可能删的不是很干净，还是要查一下一个个去删除

mysql数据库和用户删除

1. root用户登录mysql，删除hive和ambari数据：

   #取消外键约束
   SET FOREIGN_KEY_CHECKS = 1;
   
   SELECT concat('DROP TABLE IF EXISTS ', table_name, ';') FROM information_schema.tables WHERE table_schema = 'hive';
   SELECT concat('DROP TABLE IF EXISTS ', table_name, ';') FROM information_schema.tables WHERE table_schema = 'ambari';
   #先将上面两条sql查询结果执行，注意调整格式（删除掉||）
   drop database hive;
   drop database ambari; 
   #重置外键约束
   SET FOREIGN_KEY_CHECKS = 1;
   

2. 删除mysql用户：

   drop user hive@'%';
   drop user ambari@'%';
   fulsh privileges;
   

3. 查看是否删除成功：

    SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;
