一段时间没用，又忘记了我的mysql密码了，怎样去重置密码呢？
先mark下以防下次又忘记了
其实感觉mysql的数据库的加载和oracle的加载有点相似。。。

  • 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，开始！

Step # 1 : 停止sql服务

/etc/init.d/mysql stop

输出 Stopping MySQL database server: mysqld.

Step # 2: 启动mysql服务镜像

mysqld_safe --skip-grant-tables &

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

Step # 3: 以mysql服务的方式去链接数据库

mysql -u root

输出显示
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: 为root用户设置新的密码

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

Step # 5: 启动mysql服务

/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

Step # 6: 验证

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

输入这条命令按enter键后再输入密码，就能进去数据库啦！
