mysql设置不区分大小写

Posted 2021-12-10 feelsku

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

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[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
socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
lower_case_table_names=1

重启mysql：

systemctl restart mysqld
