service MysqLd stop

2.vim /etc/my.cnf

[root@VM_0_8_centos ~]# vim /etc/my.cnf

[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
