Mysql 8.4数据库安装 新建用户和库表_mysql 8.4创建数据库

1、下载MySQL数据库

yum install -y wget perl net-tools libtirpc
# 安装wget和perl、net-tools、libtirpc
wget https://dev.mysql.com/get/Downloads/MySQL-8.4/mysql-8.4.0-1.el9.x86_64.rpm-bundle.tar
# 下载安装包
tar -xvf mysql-8.4.0-1.el9.x86_64.rpm-bundle.tar
# 解压安装包
rpm -ivh mysql-community-common-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-client-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-client-plugins-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-libs-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-icu-data-files-8.4.0-1.el9.x86_64.rpm
rpm -ivh mysql-community-server-8.4.0-1.el9.x86_64.rpm

2、配置数据库

systemctl start mysqld
# 启动数据库
systemctl enable mysqld
# 设置开机启动
cat /var/log/mysqld.log
# 查看下默认密码

如图：

3、修改默认管理员密码

mysql -uroot -p
# 进入数据库
1
2

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Hadesr^000';
#修改下root初始密码，密码为：Hadesr^000

FLUSH PRIVILEGES;
# 刷新下权限

exit
# 退出

mysql -uroot -pHadesr^000
# 再重新进入，就需要新密码了

4、创建用户和数据库

CREATE USER 'Hadesr'@'localhost' IDENTIFIED BY 'Hadesr^000';
# 创建用户 Hadesr
1
2

如果需要外部远程访问，需要把'Hadesr'@'localhost'改成'Hadesr'@'%'

create database wifite character set utf8 collate utf8_bin;
# 创建 wifite 数据库
GRANT ALL PRIVILEGES ON wifite.* TO 'Hadesr'@'localhost';
# wifite数据库用户赋权

FLUSH PRIVILEGES;
# 刷新下权限

SHOW DATABASES;
# 查看数据库中的所有数据库
----------------------
mysql> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
| wifite             |

wifite.* 为数据库名字，这里只把wifite库授权给Hadesr用户，库名改成*.*，则把所有库都授权给Hadesr用户

6、创建表

1、进入wifite 库

USE wifite;
1

2、创建表

CREATE TABLE `dever` (
`name` text NOT NULL,
`ip` varchar(15) NOT NULL,
`username` text NOT NULL,
`password` text NOT NULL,
`port` char(32)
) ;

3、查询表和表结构

show  tables;
# 查询 wifite 库中表
---------------------

mysql> show  tables;
+--------------------+
| Tables_in_wifite	 |
+--------------------+
| dever              |
+--------------------+

select * from dever;
# 查询 net_dev 表结构

----------------------------------------------------------------------------
mysql> select * from dever;
+------+----------+----------+------------+------+
| name | ip       | username | password   | port |
+------+----------+----------+------------+------+
| Test | 10.1.2.3 | Hadesr   | hadesr.com | 22   |
+------+----------+----------+------------+------+

4、添加数据

1、插入数据

INSERT INTO `dever`(`name`,`ip`,`username`,`password`,`port`) VALUES ('Test','10.1.2.3','Hadesr','123456','22');
1

2、删除信息

delete from dever where name = "Test";
1

3、更新信息

update wifite.dever set password='hadesr.com' where name='Test';
1

4、使用 Navicat Premium 编辑设备信息

MySQL 下插入设备信息命令繁琐，设备多了不方便，可以使用Navicat Premium图形化进行操作
