APP
一、MySQL的下載
下載地址：https://dev.mysql.com/downloads/mysql/
?下載的文件：
二、MySQL安裝和配置
?解壓，zip格式解壓縮之后其實MySQL就可以使用了，但是要進行環(huán)境變量配置
我的電腦->屬性->高級系統(tǒng)設置->環(huán)境變量，選擇Path,在其后面添加: 你的mysql bin文件夾的路徑 ：D:installmysql-8.0.26-winx64in
?配置完環(huán)境變量之后，在D:installmysql-8.0.26-winx64目錄下新增加一個配置文件my.ini ，同時在bin的同級目錄下創(chuàng)建一個data文件夾（用于存放數據庫數據）
[client] # 設置mysql客戶端默認字符集 default-character-set=utf8 [mysqld] # 設置3306端口 port = 3306 # 設置mysql的安裝目錄 basedir=D:installmysql-8.0.26-winx64 # 設置 mysql數據庫的數據的存放目錄，MySQL 8+ 不需要以下配置，系統(tǒng)自己生成即可，否則有可能報錯 datadir=D:installmysql-8.0.26-winx64data # 允許最大連接數 max_connections=200 # 服務端使用的字符集默認為8比特編碼的latin1字符集 character-set-server=utf8 # 創(chuàng)建新表時將使用的默認存儲引擎 default-storage-engine=INNODB
?以管理員身份打開 cmd 命令行工具，即我們在Windows10系統(tǒng)的搜索框中直接輸入命令CMD。在命令提示符上單擊右鍵，選擇管理員身份運行。切換目錄：D:installmysql-8.0.26-winx64in
初始化數據庫：
mysqld --initialize --console
執(zhí)行完成后，會輸出 root 用戶的初始默認密碼，如：
D:installmysql-8.0.26-winx64in>mysqld --initialize --console 2021-10-03T15:13:48.329496Z 0 [System] [MY-013169] [Server] D:installmysql-8.0.26-winx64inmysqld.exe (mysqld 8.0.26) initializing of server in progress as process 5380 2021-10-03T15:13:48.330236Z 0 [Warning] [MY-013242] [Server] --character-set-server: 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release.

MPs)*UFna2dw就是初始密碼，后續(xù)登錄需要用到，你也可以在登陸后修改密碼。
輸入以下安裝命令：
mysqld install
啟動輸入以下命令即可：
net start mysql
結果如下：
D:installmysql-8.0.26-winx64in>mysqld install Service successfully installed. D:installmysql-8.0.26-winx64in>net start mysql MySQL 服務正在啟動 . MySQL 服務已經啟動成功。 D:installmysql-8.0.26-winx64in>
?修改密碼：alter user user() identified by '密碼';
mysql> alter user user() identified by '123456'; Query OK, 0 rows affected (0.02 sec)
在cmd中訪問MySQL服務：
