mysql use method on centos 7

1. 安装

wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

rpm -ivh mysql-community-release-el7-5.noarch.rpm

yum install mysql-server

2.启动服务

systemctl start mysqld

3.默认用户(root)无密码登陆

mysql -u root -p

4.创建个人用户,数据库,密码

create database zhanglinpengdb;

create user 'zhanglinpeng'@'localhost' identified by 'zhanglinpeng'; //最后一个字段为密码,注意

grant all on zhanglinpengdb.* to 'zhanglinpeng' identified by 'zhanglinpeng'; //授权

5.退出mysql

exit;

6,进入数据库

use zhanglinpengdb;

7.重置root用户的密码

sudo systemctl stop mysqld

sudo mysqld_safe --skip-grant-tables &

mysql -u root

use mysql;

update user SET PASSWORD=PASSWORD("password") WHERE USER='root';

flush privileges;

exit;

systemctl start mysqld

8,mysql 5.7安装在windows上,修改密码

以管理员身份运行cmd

在cmd命令行下,运行net stop mysql

转到mysql目录的bin目录下,运行命令mysqld --skip-grant-tables

新开启一个cmd。运行mysql -u root -p

进入到mysql 中后,use mysql ;

update mysql.user set authentication_string=password('123456') where user='root' and Host='localhost';

flush privileges;

exit;

关闭所有mysql进程后,重启Mysql:       net start mysql

9.导入数据库

常用source 命令

进入mysql数据库控制台,

如mysql -u root -p

mysql>use 数据库

然后使用source命令,后面参数为脚本文件(如这里用到的.sql)

mysql>source d:wcnc_db.sql
