amabari-server start错误：Table 'ambari.metainfo' doesn't exist

最近在搭建Amabari大数据集群，过程中也是几经挫折，这里主要来讲一下amabari-start过程中的Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'ambari.metainfo' doesn't exist错误。错误日志如下：

an unexpected error occured during starting Ambari Server.

按照网上大部分的教程来看都是遗漏了一个步骤：创建amabari的元数据库-ambari.metainfo。

所以，解决方案如下：

1.解决数据库连接问题：

ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java-5.1.43-bin.jar

 

2.创建元数据库：

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| ambari             |
| hive               |
| mysql              |
| oozie              |
| performance_schema |
| sys                |
+--------------------+
7 rows in set (0.00 sec)

mysql> use ambari;
Database changed
mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| ambari             |
| hive               |
| mysql              |
| oozie              |
| performance_schema |
| sys                |
+--------------------+
7 rows in set (0.00 sec)

mysql> show tables;
Empty set (0.00 sec)

mysql> source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
Query OK, 0 rows affected (0.00 sec)

 

 

现在重新执行：amabari-server restart应该就能成功启动了。

如果还有其他问题请一定要看日志！Amabari-server start错误：Table 'ambari.metainfo' doesn't exist
