Mysql找回管理員密碼,mysql管理員密碼
我們使用MYSQL的時候有可能因為種種原因忘記ROOT密碼,如果是那樣資料庫可能就廢掉了,但是今天給大家分享下找回ROOT密碼的方法或者說是在不知道root密碼的情況下修改ROOT密碼,但是還是建議大家對root密碼謹慎保管,防止一些不必要的麻煩找回管理員密碼:

[root@localhost~]# service mysqld stop

Shutting down MySQL....[確定]

[root@localhost~]# vim /etc/init.d/mysqld

大約在283行:

      $bindir/mysqld_safe --datadir="$datadir"--pid-file="$mysqld_pid_file_path" $other_args >/dev/null2>&1 &

      wait_for_pid created "$!""$mysqld_pid_file_path"; return_value=$?

更改為

      $bindir/mysqld_safe --skip-grant-tables --skip-networking

--datadir="$datadir"--pid-file="$mysqld_pid_file_path" $other_args >/dev/null2>&1 &

      wait_for_pid created "$!""$mysqld_pid_file_path"; return_value=$?
儲存退出

mysql> use mysql

You canturn off this feature to get a quicker startup with -A

 

Databasechanged

修改root密碼

mysql> update user setpassword=password('123456')  whereuser='root';

QueryOK, 3 rows affected (0.00 sec)

Rowsmatched: 3  Changed: 3  Warnings: 0

然後將服務再次停掉,然後再將摻數改回重啟mysql即可。
