mysql大小写敏感

在ubuntu16.04下安装完mysql，默认是大小写敏感的，当连接数据库查询是可能会出现如下错误：

Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table ‘express_console.SYS_USER’ doesn’t exist
Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table ‘express_console.SYS_USER’ doesn’t exist
; bad SQL grammar []; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table ‘express_console.SYS_USER’ doesn’t exist

按照网上的教程是用root帐号登录后，在/etc/my.cnf 中的[mysqld]后添加添加lower_case_table_names=1，重启MYSQL服务，这时已设置成功：不区分表名的大小写。
但是我装的mysql没有/etc/my.cnf这个文件，是在 /etc/mysql/mysql.conf.d/mysqld.cnf 文件中
在[mysqld]中添加lower_case_table_names=1
