Bat批處理命令實現一鍵安裝mysql環境

安裝mysql文件包
下載mysql-8.0.15-winx64.zip，地址是https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.15-winx64.zip

寫bat文件
把文件夾解壓縮到D盤（或解壓到其他位置），在目錄下新建初始化數據庫.bat、初始化密碼.bat和setpwd.sql

初始化數據庫.bat內代碼的內容爲

@ECHO ON
@echo 設置環境變量
@SET sqlpath=%~dp0
@setx /M PATH "%sqlpath%bin;%path%"
@echo 初始化數據庫配置文件
@del %sqlpath%\my.ini
@echo [mysqld]>>%sqlpath%\my.ini
@echo port=3306>>%sqlpath%\my.ini
@echo basedir=%sqlpath%>>%sqlpath%\my.ini
@echo datadir=%sqlpath%\data>>%sqlpath%\my.ini
@echo max_connections=200>>%sqlpath%\my.ini
@echo max_connect_errors=10>>%sqlpath%\my.ini
@echo character-set-server=utf8mb4>>%sqlpath%\my.ini
@echo default-storage-engine=INNODB>>%sqlpath%\my.ini
@echo default_authentication_plugin=mysql_native_password>>%sqlpath%\my.ini
@echo [mysql]>>%sqlpath%\my.ini
@echo default-character-set=utf8mb4>>%sqlpath%\my.ini
@echo [client]>>%sqlpath%\my.ini
@echo default-character-set=utf8mb4>>%sqlpath%\my.ini
@echo port=3306>>%sqlpath%\my.ini
@%sqlpath%\bin\mysqld.exe --initialize-insecure --lower-case-table-names=1 --user=mysql --console
@echo 開始安裝數據庫
@%sqlpath%\bin\mysqld.exe --install
@net start mysql
@pause

初始化密碼.bat內代碼的內容爲　　

@ECHO ON
@echo 初始化密碼
@SET sqlpath=%~dp0
@%sqlpath%\bin\mysql.exe -uroot < %sqlpath%\setpwd.sql
@pause

setpwd.sql內容爲

use mysql;
select Host, User from user;
update user set authentication_string='' where user='root'; 
update user set host='%' where user='root';
flush privileges;
alter user 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
flush privileges;
exitru

如需重新初始化，新建重新初始化數據庫.bat，內容爲

@ECHO ON
@echo 重新初始化
@SET sqlpath=%~dp0
net stop mysql
mysqld --remove
rmdir /s/q %sqlpath%\data
del %sqlpath%\my.ini
