1.先停止数据库服务器
service mysqld stop
2.vim /etc/my.cnf
3.配置文件添加skip-grant-tables
[root@VM_0_8_centos ~]# vim /etc/my.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-grant-tables 此处！！！！！！ # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0
4.重启数据库
systemctl restart mysql
5.登录数据库
mysql -uroot -p
如果询问密码，直接空密码登录
6.set password for root@localhost = password('123456');括号里面的密码你自己修改。
7.mysql -uroot -p123456 登录成功
PS：下面看下Mysql初始化root密码和允许远程访问
mysql默认root用户没有密码，输入mysql –u root 进入mysql
1、初始化root密码
进入mysql数据库
mysql>update user set password=PASSWORD(‘123456') where User='root';
2、允许mysql远程访问,可以使用以下三种方式:
a、改表。
mysql -u root –p mysql>use mysql; mysql>update user set host = '%' where user = 'root'; mysql>select host, user from user;
b、授权。
例如，你想root使用123456从任何主机连接到mysql服务器。
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
如果你想允许用户jack从ip为10.10.50.127的主机连接到mysql服务器，并使用654321作为密码
mysql>GRANT ALL PRIVILEGES ON *.* TO 'jack'@'10.10.50.127' IDENTIFIED BY '654321' WITH GRANT OPTION; mysql>FLUSH RIVILEGES
c:在安装mysql的机器上运行：
//进入MySQL服务器 d:\mysql\bin\>mysql -h localhost -u root //赋予任何主机访问数据的权限 mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION //使修改生效 mysql>FLUSH PRIVILEGES //退出MySQL服务器 mysql>EXIT
