windows下mysql默认是不区分大小写的，但是linux会区分大小写，所以当执行的sql语句有大小写区别时需要注意。
那么怎么设置mysql不区分大小写。
1.windows下
到安装mysql的目录，修改my.ini文件
在文件最后一行加上下面一句话
lower_case_table_names=1
lower_case_table_names = 1说明 0：区分大小写，1：不区分大小写
效果如下
[mysqld]
port = 3306  basedir=F:/mysql-5.7.21-winx64
datadir=F:/mysql-5.7.21-winx64/data
max_connections=200  character-set-server=utf8
default-storage-engine=INNODB  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[mysql]
default-character-set=utf8  lower_case_table_names=1
重启mysql
2.linux下
进入etc下面
cd /etc/
编辑my.cnf文件
vi my.cnf
最后一行加上下面一句
lower_case_table_names=1
效果如下

#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pidlower_case_table_names=1
重启mysql：
systemctl restart mysqld
