windows同时安装 5.7 8.0 mysql

这篇文章介绍了windows同时安装 5.7 8.0 mysql，分享给大家做个参考，收藏Java资料网收获更多编程知识

电脑配置升级了，想着自己电脑本地安装数据库，重新学习一下MySQL，下面记录了本地Windows安装两个版本MySQL的过程。

一.安装5.7版本

(1)在解压目录创建配置文件 - my.ini

[mysqld]
# set basedir to your installation path
basedir=D:/Program/mysql/mysql-5.7.24-winx64
# set datadir to the location of your data directory
datadir=D:/Program/mysql/mysql-5.7.24-winx64/data

(2)创建data文件夹，初始化数据目录：注意有两种选项

• --initialize：默认的安全安装模式，会生成随机初始的root密码，这种情况下，密码被标记为过期，第一次登陆进去后需要设置新的密码
• --initialize-insecure：不安全的安装模式，不会root生成密码
• --user：指定用户

## 初始化数据目录，使用第一种方式
PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqld --initialize --user=hecg95

(3)首次启动：

## 启动MySQL
PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqld --console

(4)查找密码及修改密码：

• 随机密码在data目录下的hqiogwdt0114.err文件中：wD2q)XQF%*nz

  2020-01-06T12:04:46.034179Z 1 [Note] A temporary password is generated for root@localhost: wD2q)XQF%*nz
  

• 使用初始密码登陆MySQL，重新设置新的密码：

  PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysql -u root -p
  Enter password: ************

  Query OK, 0 rows affected (0.00 sec)
  
  mysql> exit
  Bye
  PS D:\Program\mysql\mysql-5.7.24-winx64\bin>
  

• 使用mysqladmin关闭和重新启动MySQL：

  PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqladmin -u root shutdown
  mysqladmin: connect to server at 'localhost' failed
  error: 'Access denied for user 'root'@'localhost' (using password: NO)'

  ## 重新启动 --console 会输出日志
  PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqld --console

二.安装8.0版本

(1)在解压目录创建配置文件 - my.ini

[mysqld]
# set basedir to your installation path
basedir=D:/Program/mysql/mysql-8.0.18-winx64
# set datadir to the location of your data directory
datadir=D:/Program/mysql/mysql-8.0.18-winx64/data
# 多个MySQL时,修改port,换个端口号
port = 13306

(2)创建data文件夹，初始化数据目录：注意有两种选项

• --initialize：默认的安全安装模式，会生成随机初始的root密码，这种情况下，密码被标记为过期，第一次登陆进去后需要设置新的密码
• --initialize-insecure：不安全的安装模式，不会root生成密码，默认为空密码
• --user：指定用户
• 参考官网的文档 - 2.10.1 Initializing the Data Directory

## 初始化数据目录，使用第二种方初始化自动创建data文件夹
PS D:\Program\mysql\mysql-8.0.18-winx64\bin> .\mysqld --initialize-insecure --user=hecg95

(3)首次启动：

## 启动MySQL
PS D:\Program\mysql\mysql-8.0.18-winx64\bin> .\mysqld --console

(4)初次登陆及修改密码：

• 查看data目录下的hqiogwdt0114.err文件：提示目前使用默认的空密码

  2020-01-06T12:51:51.897459Z 5 [Warning] [MY-010453] [Server] root@localhost is created with an empty password ! Please consider switching off the --initialize-insecure option.

• 使用空密码登陆MySQL，重新设置新的密码：

  在MySQL 8.0中，默认的身份验证插件已从更改 mysql_native_password为 caching_sha2_password，并且 'root'@'localhost'管理帐户caching_sha2_password默认使用。

  PS D:\Program\mysql\mysql-8.0.18-winx64\bin> .\mysql -P 13306  -u root -p
  Enter password:

• 使用mysqladmin关闭和重新启动MySQL：
