mysql常見錯誤，telnet

1.[ERROR] InnoDB: Data file /usr/local/mysql-5.6.30/data3306/ibdata1 is of a different size

[root@localhost mysql]# less /etc/my.cnf |grep innodb_data_file_path
innodb_data_file_path = ibdata1:200M:autoextend
[root@localhost mysql]# ls -lh /var/lib/mysql/ibdata1
-rw-rw---- 1 mysql mysql 18M Nov 12 22:00 /var/lib/mysql/ibdata1
由於參數設置和實際的文件大小不一致，啟動mysql出現了上述的故障
此時我們可以選擇修改my.cnf文件的配置或者直接注釋掉這個參數設置，讓mysql啟動時用默認參數去檢驗
或者My.cnf文件中指定該參數等於實際文件的大小
[root@localhost mysql]# less /etc/my.cnf |grep innodb_data_file_path
innodb_data_file_path = ibdata1:18M:autoextend
