mysql5.7.10 zip windows安装

从该网址下载mysql社区版http://dev.mysql.com/downloads/mysql/

将其解压到自己电脑的一个目录，例如笔者的目录为D:\Program Files\mysql-5.7.10-winx64

将该目录添加到系统的环境变量path中

在解压的目录之中复制my-default.ini的内容，新建一个文件，命名为my.ini，将内容粘贴进去，目录结构如下所示：



之后修改my.ini文件，文件内容如下，其中注意的地方已标出：

之后保存文件，打开cmd命令行窗口，注意已管理员身份运行，进入mysql的目录，即D:\Program Files\mysql-5.7.10-winx64

执行以下命令

mysqld  -install

将mysql安装为服务

接着启动服务

net start mysql

此时出错

在网上查看资料，以及参考mysql官方文档点击打开链接，需要初始化手动初始化data文件夹

命令为

mysqld --initialize

之后再执行

net start mysql

服务顺利启动

之后需要修改root的密码

输入命令mysql -u root

报错  说 root@localhost 有密码，需要密码才能登录

问题出在了手动初始化data文件夹To initialize the data directory, invoke mysqld with the --initialize or --initialize-insecure option, depending on whether you want the server to generate a random initial password for the 'root'@'localhost' account.

官方 文档说

To initialize the data directory, invoke mysqld with the --initialize or --initialize-insecure option, depending on whether you want the server to generate a random initial password for the 'root'@'localhost' account.

Regardless of platform, use --initialize for “secure by default” installation (that is, including generation of a random initial root password). In this case, the password is marked as expired and you will need to choose a new one. With the --initialize-insecure
option, no root password is generated; it is assumed that you will assign a password to the account in timely fashion before putting the server into production use.

大概意思是采用 --initialize 和 --initialize-insecure两种方式生成data文件夹，但是--initalize会随机生成一个密码分配给root@localhost，而--initialize-insecure不会生成密码，我使用了--initialize，继续查看文档

Connect to the server:

If you used --initialize but not --initialize-insecure to initialize the data directory, connect to the server as root using the random password that the server generated during the initialization sequence:

shell> mysql -u root -p

Enter password: (enter the random root password here)
Look in the server error log if you do not know this password.

If you used --initialize-insecure to initialize the data directory, connect to the server as root without a password:

shell> mysql -u root --skip-password

可以在error日志文件中找到，到D:\Program Files\mysql-5.7.10-winx64中的data文件夹下，发现一个以自己计算机名称为名，以.err为后缀的文件，打开



发现在第8行有一个临时密码被生成为47rhFKYdyC/k

重新登录

mysql -u root -p

输入密码 47rhFKYdyC/k

顺利登录

修改root密码

set password for root@localhost password("新密码")

或者采用命令

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';修改命令

即可
