使用mysql_install_db初始化mysql提示：mysql Plugin ‘InnoDB’ init function returned error的解决方法

mysql Plugin ‘InnoDB’ init function returned error

解决方法：

删除log文件和data的初始化文件

删除的文件如下：aria_log.00000001、aria_log_control、ib_logfile0、ib_logfile1、bi_data、ibdata1

重新运行mysql_install_db --user=mysql --datadir=/data/***/

再启动

注意： 修改数据目录的权限，要不容易出现“Can't create test file /var/lib/mysql/Xiaojia.lower-test“ 这个问题。
