docker mysql 5.7以上支援中文編碼問題
問題在部署時一直報錯：
django.db.utils.OperationalError: (1067, "Invalid default value for 'project_name'")
查了下就是不支援中文輸入和讀取

圖上的第一個 connection 就是我們通過workbench等客戶端連線的時候指定的編碼。
外部訪問資料亂碼的問題就出在這個connection連線層上
1.先解決外部訪問資料亂碼的問題
SET NAMES 'utf8';它相當於下面的三句指令：
SET character_set_client = utf8;
SET character_set_results = utf8;
SET character_set_connection = utf8;
進入mysql docker 容器修改配置my.cnf
docker 裡面安裝vim，：
apt-get update
apt-get install vim接下來編輯my.cnf，在mysqld下面黏貼幾個玩意
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci重啟docker的mysql容器，解決 :
docker restart mysql
