本地環(huán)境：
python2.7.15
MySQL8.0
MySQL-python 1.2.5
執(zhí)行：
>>> import MySQLdb
>>> conn = MySQLdb.connect(host="localhost",user="root",passwd="123456",db="sunck")
遇到報(bào)錯(cuò)：
_mysql_exceptions.OperationalError: (1251, 'Client does not support authentication protocol requested by server; consider upgrading MySQL client')
解決辦法：
命令行輸入：
mysql -u root -p
輸入密碼
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
mysql> FLUSH PRIVILEGES;
更改密碼后需用flush privileges刷新MySQL的系統(tǒng)權(quán)限相關(guān)表访圃，否則會(huì)出現(xiàn)拒絕訪問岩遗，還有一種方法，就是重新啟動(dòng)mysql服務(wù)器叶雹，來使新設(shè)置生效着憨。
