[Full-stack Development Guide] Enable remote login for Mysql8 (docker-compose installation)

1. Log in and configure mysql

1. Login container

docker exec -it 53e85183fdc0 /bin/bash

2. Edit file

vim   /etc/mysql/conf.d/docker.cnf

3. Add skip-grant-tables

skip-grant-tables

4. Restart container

docker-compose -f docker-compose.yml restart

5. Mysql8 adds new users and does not support GRANT ALL PRIVILEGES ON . TO 'root'@'%'

create user 'admin'@'%' identified by '数据库密码';

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%';

flush privileges;

ALTER USER 'admin'@'%' IDENTIFIED WITH mysql_native_password BY '数据库密码';

flush privileges;

2. Solve the group by problem

java.sql.SQLSyntaxErrorException: Expression #14 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'yxkt.provinceDistrict.name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

1. Modify the mysql configuration file /etc/mysql/conf.d/my.cnf

vim  /etc/mysql/conf.d/my.cnf

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

2. Restart mysql

 docker restart [mysql容器名称或ID]
