忘记MySQL(和PHP搭配之最佳组合) ROOT密码是在MySQL(和PHP搭配之最佳组合)使用中很常见的问题,可是有很多朋友并不会重置ROOT密码,那叫苦啊,我有深有感触,特写此文章与大家交流:
1、编辑MySQL(和PHP搭配之最佳组合)配置文件:
windows环境中:%MySQL(和PHP搭配之最佳组合)_installdir%\my.ini //一般在MySQL(和PHP搭配之最佳组合)安装目录下有my.ini即MySQL(和PHP搭配之最佳组合)的配置文件。
linux环境中:/etc/my.cnf
在[MySQL(和PHP搭配之最佳组合)d]配置段添加如下一行:
skip-grant-tables
保存退出编辑。
2、然后重启MySQL(和PHP搭配之最佳组合)服务
windows环境中:
net stop MySQL(和PHP搭配之最佳组合)
net start MySQL(和PHP搭配之最佳组合)
linux环境中:
/etc/init.d/MySQL(和PHP搭配之最佳组合)d restart
3、设置新的ROOT密码
然后再在命令行下执行:
MySQL(和PHP搭配之最佳组合) -uroot -p MySQL(和PHP搭配之最佳组合)
直接回车无需密码即可进入数据库了。
现在我们执行如下语句把root密码更新为 7758521:
update user set password=PASSWORD("123456") where user='root';
quit 退出MySQL(和PHP搭配之最佳组合)。
4、还原配置文件并重启服务
然后修改MySQL(和PHP搭配之最佳组合)配置文件把刚才添加的那一行删除。
再次重起MySQL(和PHP搭配之最佳组合)服务,密码修改完毕。
修改完毕。
用新密码123456试一下吧,又能登入MySQL(和PHP搭配之最佳组合)的感觉就是不一样吧?
