show variables like ‘character%’;
SET NAMES utf8mb4;
SET CHARACTER SET utf8mb4;
中文乱码永久方案：
vim /etc/my.cnf
[client]
default-character-set=utf8mb4[mysql]
default-character-set=utf8mb4[mysqld]
character-set-client-handshake=FALSE
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
无法输入中文解决方案：
添加环境变量：
env LANG=C.UTF-8
docker exec -it b18f56aa1e15 env LANG=C.UTF-8 /bin/bash
docker-compose.yml
