win10 安装MySQL过程和遇到的坑

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:\Users\Administrator.JX-201906191059>cd "C:\Program Files\MySQL\MySQL Server 5.7\bin"

第二步：安装MySQL服务（不进行这步，MySQL不会在服务中）

C:\Program Files\MySQL\MySQL Server 5.7\bin>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 Files\MySQL\MySQL Server 5.7

datadir=F:\MySQL\data

#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。

key_buffer_size = 16M

max_allowed_packet = 1M

sort_buffer_size = 512K

net_buffer_length = 8K

read_buffer_size = 256K

read_rnd_buffer_size = 512K

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

C:\Program Files\MySQL\MySQL Server 5.7\bin>mysqld --initialize
