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

5 rowsin set (0.01 sec)
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。
