查看当前数据库大小写敏感配置：
[root@iZ2zehcucevs54589utu1eZ ~]# mysql -uroot -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 235 Server version: 10.6.4-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement. MariaDB [(none)]> show variables like ‘%case%‘; +-----------------------------------------+-------+ | Variable_name | Value | +-----------------------------------------+-------+ | lower_case_file_system | OFF | | lower_case_table_names | 0 | | simple_password_check_letters_same_case | 1 | +-----------------------------------------+-------+ 3 rows in set (0.001 sec) MariaDB [(none)]>
参数含义：
lower_case_table_names： 此参数不可以动态修改，必须重启数据库
lower_case_table_names = 1 表名存储在磁盘是小写的，但是比较的时候是不区分大小写
lower_case_table_names=0 表名存储为给定的大小和比较是区分大小写的
lower_case_table_names=2, 表名存储为给定的大小写但是比较的时候是小写的
修改方式：
修改/etc/my.cnf，添加如下内容：
[mysqld]
lower_case_table_names=1
添加后重启数据库，并查看修改状态：
