ERROR 1396 (HY000): Operation CREATE USER failed for 'root'@'localhost'

安裝ranger時MySQL報錯，查看MySQL數據庫，發現host=localhost這一列被刪除了，插入這一列就好了，具體操作如下：

解決辦法：

進入MySQL數據庫

use mysql:
insert into user(Host,User,Password) values("localhost","%",password("123456"))
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '123456' WITH GRANT OPTION;
flush privileges;

 

 然后重新執行etup.sh 就正常了。
