在测试`SForum`程序中使用到的部分关于数据库的操作
|
||
## 安装Mariadb服务器
|
||
```
|
||
apt install mariadb-server-10.6
|
||
```
|
||
## 初始化数据库
|
||
```
|
||
mysql_secure_installation
|
||
```
|
||
## 连接数据库
|
||
```
|
||
mysql -u root -p
|
||
```
|
||
|
||
## 创建数据库
|
||
```
|
||
CREATE DATABASE bbs;
|
||
```
|
||
|
||
## 创建一个本地访问数据库的账户
|
||
### 创建用户
|
||
```
|
||
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
|
||
```
|
||
### 参数：
|
||
`username`：数据库访问的账户；`localhost`：数据库的访问方式,外网访问的时候用%替换localhost即可；`password`：数据库访问密码，此处输入密码明文；
|
||
|
||
## 给测试账户分配权限
|
||
|
||
### 分配所有权限
|
||
|
||
给用户分配所有的权限，并且通过localhost访问
|
||
```
|
||
GRANT ALL ON bbs.* to username@'localhost' IDENTIFIED BY 'password';
|
||
FLUSH privileges;
|
||
```
|
||
### 分配部分权限
|
||
|
||
#### 给账户分配部分的权限，并且通过外网访问
|
||
```
|
||
GRANT insert,delete,select,update ON test.* to username@'%' IDENTIFIED BY 'password';
|
||
FLUSH privileges;
|
||
```
|
||
|
||
#### 或则采用下面的代码，除了操作权限授权外，还赋予授权的权限。
|
||
```
|
||
GRANT ALL ON test.* to username@'%' IDENTIFIED BY 'passowrd' WITH GRANT OPTION;
|
||
FLUSH privileges;
|
||
``` |
