[ERROR] [MY-012263] [InnoDB] The Auto-extending innodb_system data file './ibdata1' is of a different sizethan specified in the .cnf file: initial 65536 pages, max 0 (relevant if non-zero) pages!

 实际my.cnf发现里面的innodb_data_file_path = ibdata1:1G:autoextend  设置得太大，我这机器容量小，所以调到12M ，

innodb_data_file_path = ibdata1:12M:autoextend
