mysql重設密碼

wulilideMacBook-Pro:bin wulili$ mysql start

ERROR 1045 (28000): Access denied for user 'wulili'@'localhost' (using Macpassword: NO) woo​​oal-fulBookoo su - root

1、吧mysql服務關閉

2、

 啟動mysqld_safe ，跳過啟動授權表。啟動時加上skip-grant-tables參數目的是在啟動mysql時不啟動grant-tables，授權表。這樣就可以修改root的密碼了。

# mysqld_safe --skip-grant-tables &

# mysqld_safe --skip-grant-tables &
