Second, install mysql database

I am here to use zip file installation, which is free to install and configure the contents of a little more

1. Unzip the installation file

• Note: Unzip the path which do not appear in Chinese! ! !
  

2. Configure mysql

• Double-click to enter to see the bindirectory
  

• New dataFolder
• And then create a text file, rename it my.ini(note that your computer may not display filename extension, my.inifile not on the datafolder)
  
• Use a text editor to open my.inithe file, copy the following text into the configuration my.inifile

• Modify the contents of your computer's configuration (be sure to remove all Chinese text row content)
  

• Save and close the editor

[mysqld]
# 设置服务端使用的字符集为utf-8
character-set-server=utf8
# 绑定IPv4地址
bind-address = 0.0.0.0
# 设置mysql的端口号
port = 3306
# 设置mysql的安装目录(能看到bin即可)
basedir=D:\Applocations\64_mysql\mysql-5.7.28-winx64
# 设置mysql数据库的数据的存放目录(能看到my.ini文件的目录)
datadir=D:\Applocations\64_mysql\mysql-5.7.28-winx64\data
# 允许最大连接数
max_connections=2000
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 设置mysql以及数据库的默认编码
[mysql]
default-character-set=utf8
[mysql.server]
default-character-set=utf8
# 设置客户端默认字符集
[client]
default-character-set=utf8

3. Install mysql

• Enter the bin/directory
• In the address bar cmdand press Enter cmd to open a command line terminal
  

Chinese path can not contain the address, if not pay attention to the front, can be cut at the installation files to mysql path plain English

• The installation commands in cmd terminal

# 安装命令
mysqld --install
# 卸载命令
mysqld --remove

Tip a successful installation

4. Initialize mysql

• Continue initialization command in Terminal (you can initialize several times, but each must empty datafolder)

# mysql数据库初始化
mysqld --initialize --user=root --console

• After execution is completed, it will give the mysql rootuser is assigned a random password, as
  

5. landing mysql

• In the Terminal Services start mysql command

# 启动mysql服务
net start mysql
# 停止mysql服务
net stop mysql

• Use the command mysql connection

  注:这个密码就是前面初始化mysql生成的随机密码

mysql -uroot -p密码
mysql -uroot -p

6.修改mysql的密码

默认随机密码也可以使用，但是太难记了，可以设置一个简单的密码

• 执行下面的命令设置mysql的密码

# 设置mysql的密码
set password = password('密码');
# 退出mysql数据库 
exit

7.配置mysql的环境变量

• 以此'此电脑'-->'属性'-->'高级系统设置'-->'环境变量'
  

• 在系统变量下新建系统变量

变量名:MYSQL_HOME
变量值:D:\Applocations\64_mysql\mysql-5.7.28-winx64(能看到bin目录的mysql解压路径)

• 在path下新增环境变量

%MYSQL_HOME%\bin

重新随意打开cmd终端，使用命令加修改的密码，就可以直接连接mysql了

三、mysql数据库添加用户

root用户是mysql数据库的超级用户，权限比较高，使用起来不安全，推荐新建用户，当然不新建也可以的

在终端里使用以下命令新建用户并授予权限

# 格式说明
grant 权限 on 数据库.表 to 用户名@连接的ip地址 identified by'密码';
# 实例，给密码是1234的test用户所有数据库的所有表的所有权限
grant all on *.* to test@'%' identified by'1234';

到此为止mysql安装完成，可以使用navicat连接数据库了
