我在我的fedora机器上安装了mysql服务器。现在我想在另一个端口上的同一台机器上运行另一个mysql服务器实例。
为此，我需要创建一个不同的数据目录。 Mysql服务器安装在默认位置/ usr / local / mysql上，默认数据目录位置是/ usr / local / mysql / data
现在我在发出此命令时创建新数据目录
./scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql2
它给了我很多错误，innodb说的是
InnoDB: Error number 17 means 'File exists'.

2014-04-29 10:31:51 32072 [ERROR] InnoDB: The file './mysql/innodb_table_stats.ibd' already exists though the corresponding table did not exist in the InnoDB data dictionary. Have you moved InnoDB .ibd files around without using the SQL commands DISCARD TABLESPACE and IMPORT TABLESPACE, or did mysqld crash in the middle of CREATE TABLE? You can resolve the problem by removing the file './mysql/innodb_table_stats.ibd' under the 'datadir' of MySQL.
ERROR: 1813 Tablespace for table '`mysql`.`innodb_table_stats`' exists. Please DISCARD the tablespace before IMPORT.

我在这里做错了吗？
