2017最新版windows安装mysql教程

1.首先在mysql官网下载最新版mysql, 附上链接点击打开链接,根据你的系统型号选择对应的包下载,大约300多兆,版本号为5.7.19

下载完之后,解压缩,是一个标准的mysql文件,如图

2.第二步,配置系统环境变量,桌面→我的电脑→右键"属性"→高级系统设置→环境变量→系统变量→新建

变量名可以根据喜好随便取,我这里叫做MYSQL_HOME,变量值是你刚刚下载的mysql文件夹所在的目录,我们指向其中的bin目录,然后一路确定返回

3.我们的mysql文件中没有默认的配置文件,我们新建一个.ini的配置文件,名字为my-default.ini,里边内容如下:

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.6/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.

4.准备安装mysql,通过命令行工具安装

首先以管理员身份启动cmd !!!注意!!!,一定要以管理员身份启动,否则后面会报错,提示权限不够

命令如下: mysqld -install 如果出现以下提示,说明安装成功

然后开始启动服务,命令: net start mysql

这时候报错了,提示无法启动,3534 ,我们通过 mysqld --console命令来查看错误日志

这里提示,mysql文件夹下没有\data这个文件或者路径,这时我们新建一个

我们用命令进入到mysql文件夹的路径,输入以下命令:

  mysqld --initialize-insecure --user=mysql

这时我们再重新启动mysql,发现就能正常启动了

至此.我们安装mysql就成功了
