Mysql密碼重置

一段時間沒用，又忘記了我的mysql密碼了，怎樣去重置密碼呢？
先mark下以防下次又忘記了
其實感覺mysql的數據庫的加載和oracle的加載有點相似。。。

• Step # 1: Stop the MySQL server process.
• Step # 2: Start the MySQL (mysqld) server/daemon process with the –skip-grant-tables option so that it will not prompt for password.
• Step # 3: Connect to mysql server as the root user.
• Step # 4: Setup new mysql root account password i.e. reset mysql password.
• Step # 5: Exit and restart the MySQL server.

ok，五步，開始！

Step # 1 : 停止sql服務

/etc/init.d/mysql stop

輸出 Stopping MySQL database server: mysqld.

Step # 2: 啓動mysql服務鏡像

mysqld_safe --skip-grant-tables &

輸出
Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe

Step # 3: 以mysql服務的方式去鏈接數據庫

mysql -u root

輸出顯示
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 4.1.15-Debian_1-log
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>

Step # 4: 爲root用戶設置新的密碼

mysql> use mysql;
mysql> update user set password=PASSWORD("你的密碼") where User='root';
mysql> flush privileges;
mysql> quit

Step # 5: 啓動mysql服務

/etc/init.d/mysql stop

Stopping MySQL database server: mysqld
STOPPING server from pid file /var/run/mysqld/mysqld.pid
mysqld_safe[6186]: ended
[1]+ Done mysqld_safe --skip-grant-tables</pre>

Step # 6: 驗證

 /etc/init.d/mysql start
 mysql -u root -p

輸入這條命令按enter鍵後再輸入密碼，就能進去數據庫啦！
