作为关系型数据库的一种 ,mysql 因其占用内存小和开源等特性而兴起 . 下面简单介绍下关于 mysql 配置和简单的操作 .
mysql 配置
1. 安装文件的下载
免安装版 下载地址 :http://dev.mysql.com/downloads/file.php?id=452189
下载后是一个压缩文件 , 解压后放在你想放的位置就可以了 . 建议还是靠近根目录比较好 .
2. 配置环境变量
2.1 新建一个 mysqlhome 或者什么的都可以 . 值为上一步的解压缩目录
2.2 将 mysqlhome 放在 Path 目录就好了
这里其实也可以直接将这个 bin 文件放在 path 下面 . 建立一个独立的环境变量来独立操作这样在下次更改安装 mysql 目录时不用去修改 path 了 ,path 里面包含了很多安装软件的目录 . 频繁操作可能带来误操作 . 这样也就相当于我们软件中的解耦 , 独立变化 , 减少修改了 .
3. 启动 mysql 服务
netstart吻钓L服务正在启动-吻sqL服务已经启动成功。",sql启动服务:喇夕SQL腼夕sql一5。6。19一公inx64喃in>生:" />
如图所示 , 在开始的时候因为我安装了一个安装版的 mysql, 我在安装 mysql 服务时提示我已经存在 . 执行 mysqld -remove, 删除已经存在的服务就可以了。第二次执行 mysqld -install ,提示安装成功。然后就是启动服务了!
罗列一下这些命令:
a. 安装服务
mysqld -install
b. 删除服务
mysqld -remove
c. 启动服务
net start mysql
这时候服务启动,整个 mysql 安装配置工作就基本结束了。
常用操作
在安装好 mysql 后,软件默认的 root 用户的密码为空。
1.进入mysql
2.创建数据库
3.创建表格
4.插入数据
5.显示数据库、表信息
总结,mysql的部署和配置和之前简单了解的mongdb还是挺类似的。有了之前在mongdb配置
的经历,这里对于dos界面没有之前陌生了。配置过程还是挺顺利了,还有一些其他的操作关于
权限的问题之后再去了解。还有Navicat Premium客户端,配置了可视化的界面针对的操作。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
