环境：win10系统，MySQL5.7.18 “mysql-5.7.18-winx64.msi”
首先是要运行mysql-5.7.18-winx64.msi，选择安装在C盘（可自定义安装）
第一步
打开命令控制台Cmd ，并进入MySQL安装目录bin目录中
C:UsersAdministrator.JX-201906191059>cd "C:Program FilesMySQLMySQL Server 5.7in"
第二步：安装MySQL服务（不进行这步，MySQL不会在服务中）
C:Program FilesMySQLMySQL Server 5.7in>mysqld --install
Service successfully installed.
第三步：初始化数据库，在这之前需要先创建my.ini配置文件,放在MySQL安装目录
#### my.ini文件 start #### 更多配置请百度！！！
[client]
port = 3306
default-character-set=utf8
[mysqld]
skip-grant-tables
port = 3306
character_set_server=utf8
#安装目录
basedir=C:Program FilesMySQLMySQL Server 5.7
#data目录与安装目录分离
datadir=F:MySQLdata
#红色参数解决下面 #错误一
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER
#以下配置，详情可以百度。

myisam_sort_buffer_size = 8M
explicit_defaults_for_timestamp=true
#错误日志文件
log-error=F:/MySQL/log/mysql-err.log
#### my.ini文件 END ####
#错误一

启动MySQL：
恭喜 MySQL服务可以使用了
客户端工具推荐：
好用才是王道……
