一段時間沒用，又忘記了我的mysql密碼了，怎樣去重置密碼呢凸椿？
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。翅溺。脑漫。
- 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，五步咙崎，開始优幸！
Step # 1 : 停止sql服務
/etc/init.d/mysql stop
輸出 Stopping MySQL database server: mysqld.
Step # 2: 啟動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: 為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: 啟動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鍵后再輸入密碼，就能進去數據庫啦叙凡！
