Symlinks are fully supported only for MyISAM
tables.
对应Innodb引擎数据文件放到其他目录
mysql> SHOW VARIABLES LIKE 'innodb_file_per_table';
+-----------------------+-------+
| Variable_name | Value |
+-----------------------+-------+
| innodb_file_per_table | ON |
+-----------------------+-------+
mysql> CREATE TABLE y666 (c1 INT PRIMARY KEY) TABLESPACE = innodb_file_per_table
DATA DIRECTORY = '/usr/local/mysql/mydata';
建完再目录下(库名test下)
[root@centos_TP test]# dir
y666.ibd
如果在主从环境中建表,必须保证复制的其他数据库路径有,并且不能报错,如:/usr/local/mysql/mydata
否则同步复制会报错!
