Linux安装地址：https://www.cnblogs.com/miskis/p/6038645.html 一键安装卸载批处理脚本：https://share.weiyun.com/VwOhWYWV

以管理员运行脚本，按提示操作修改登录密码即可！

一、绿色版安装

1、下载MySQL 8.0.16，地址：http://dev.mysql.com/downloads/mysql/ （选择32位或者64位版本需根据自身PC情况）

2、解压到你自己的磁盘

3. 配置Path路径：系统属性 => 高级 => 高级 => 系统变量 => path后添加 (如：D:Toolsmysql-8.0.16-winx64bin)

4. 在mysql根目录下新建 my.ini，此文件是初始化信息（默认mysql根目录不存此文件）：

# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # These are commonly set, remove the # and set as required. basedir = D:Toolmysql-8.0.20-winx64 datadir = D:Toolmysql-8.0.20-winx64data port = 3306 # server_id = ..... # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES # Windows下忽略大小写 lower_case_table_names=2 [WinMySQLadmin] Server = D:Toolmysql-8.0.20-winx64binmysqld.exe

5. 以管理员身份打开“命令行窗口”，输入命令 mysqld --initialize-insecure --user=mysql

执行这条命令需要花一定的时间(大概几秒，根据电脑情况)，不会有返回结果，但是可以在MySQL的安装目录下看到，原本为空的data文件夹里面有了许多文件和文件夹

6. 输入命令mysqld -install ，当看到Service successfully installed时，表示Mysql服务添加成功

7. 输入命令net start mysql，启动Mysql服务

8.登录mysql后，修改密码（默认密码为空）

（1）以管理员身份打开“命令行窗口”，输入mysql -uroot -p并按下回车键

（2）在弹出Enter password: 时，继续按下回车键，即可登录mysql

（3）输入命令use mysql;

（4）输入命令ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码'; （注意末尾要有分号）

（5）输入命令flush privileges;

（6）输入命令exit;

9.解决远程无法登录错误

//使用root登录mysql mysql -u root -p //切换数据库 mysql>use mysql; //修改数据 mysql>update user set host = '%' where user = 'root'; //查询数据 mysql>select host, user from user; //允许远程使用root账号登录 mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; //刷新权限 mysql>flush privileges;

mysql 8.0.25 版本允许远程登录连接命令：

进入mysql控制台， 1、use mysql; 2、update user set host='%' where user='root'; 3、flush privileges; 4、alter user 'root'@'%' identified by '12345678' password expire never; 5、alter user 'root'@'%' identified with mysql_native_password by '12345678'; 6、flush privileges;

到处安装完成！
