如何在MySQL中复位根用户密码
如果你从未为MySQL设置根用户密码,服务器在以根用户身份进行连接时不需要密码。但是,建议你为每个账户设置密码。 如果你以前设置了根用户密码,但却忘记了该密码,可设置新的密码。下述步骤是针对Windows平台的。在本节后面的内容中,介绍了针对Unix平台的
如果你从未为MySQL设置根用户密码,服务器在以根用户身份进行连接时不需要密码。但是,建议你为每个账户设置密码。
如果你以前设置了根用户密码,但却忘记了该密码,可设置新的密码。下述步骤是针对Windows平台的。在本节后面的内容中,介绍了针对Unix平台的步骤。
在Windows平台下,该步骤是:
以系统管理员身份登录到系统。
如果MySQL服务器正在运行,停止它。对于作为Windows服务运行的服务器,,进入服务管理器:
开始菜单->控制面板->管理工具->服务
然后在列表中找出MySQL服务器,并停止它。
如果服务器不是作为服务而运行的,可能需要使用任务管理器来强制停止它。
创建1个文本文件,并将下述命令置于单一行中:
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPassword');
用任意名称保存该文件。在本例中,该文件为C:mysql-init.txt。
打开控制台窗口,进入DOS命令提示:
开始菜单->运行-> cmd
假定你已将MySQL安装到C:mysql。如果你将MySQL安装到了另一位置,请对下述命令进行相应的调整。
在DOS命令提示符下,执行命令:
C:> C:mysqlbinmysqld-nt --init-file=C:mysql-init.txt
在服务器启动时,执行由“--init-file”选项命名的文件的内容,更改根用户密码。当服务器成功启动后,应删除C:mysql-init.txt。
如果你使用MySQL安装向导安装了MySQL,或许需要指定“--defaults-file”选项:
C:> C:Program FilesMySQLMySQL Server 5.1binmysqld-nt.exe
--defaults-file="C:Program FilesMySQLMySQL Server 5.1my.ini"
--init-file=C:mysql-init.txt
使用服务管理器,可找到恰当的“--defaults-file”设置:
开始菜单->控制面板->管理工具->服务
在列表中找出MySQL服务,右击,并选择“属性”选项。在可执行字段的Path(路径)中包含“--defaults-file”设置。
停止MySQL服务器,然后在正常模式下重启它。如果以服务方式运行服务器,应从Windows服务窗口启动它。如果以手动方式启动了服务器,能够像正常情形下一样使用命令。
应能使用新密码进行连接。
