encounter the same problem, look through the MySQL official document and find

lower_case_table_names can only be configured when initializing the server. Changing the lower_case_table_names setting after the server is initialized is prohibited.

Don't count on it. Change it

after an attempt, it is valid to modify my.cnf
and then initialize the database only after the installation is complete and before initializing the database.

if you don't care about data, delete data directly
1 stop MySQL
2 delete MySQL data / var/lib/mysql
3 modify the lower_case_table_names = 1
4 start mysql
4 get

speaking, I am a member of the docker Party. Give me a piece of my own advice:

use docker mysql image

configuration and startup are simple, and you can start as many as you want. Please refer to my blog post:
Docker about the use of mysql images
