言歸正傳
一，在windows下設置
1，到安裝mysql的目錄，修改my.ini文件，如果沒有，則創建一個
2，在[mysql]的下面加上一句話
lower_case_table_names=1
如圖
3，重啓mysql
二，在linux下設置
1，進入etc下面
cd /etc/
2，編輯my.cnf文件
vi my.cnf
3，同樣在[mysql]下面一句
lower_case_table_names=1
4，完整文件
# For advice on how to change settings please see

[mysqld]
#
# 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
#datadir=/var/lib/mysqldata
socket=/var/lib/mysql/mysql.sock
#socket=/var/lib/mysql/mysql1.sock
server_id = 1
expire_logs_days = 3
max_allowed_packet = 50M
# skip-grant-tables = 1
local-infile=0
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character_set_server=utf8
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
# 0爲區分大小寫，1爲不區分大小寫
lower_case_table_names=1
5，重啓mysql：
systemctl restart mysqld
總結：此時再次進入項目，連接數據庫，就不會報大小寫錯誤了。
