windows同时安装 5.7 8.0 mysql

电脑配置升级了，想着自己电脑当地安装数据库，重新学习一下MySQL，下面记载了当地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

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

复制代码

(2)创建data文件夹，初始化数据目录：留意有两种选项

• --initialize：默认的安全安装模式，会天生随机初始的root暗码，这种情况下，暗码被标记为过期，第一次登岸进去后需要设置新的暗码
  
• --initialize-insecure：不安全的安装模式，不会root天生暗码
  
• --user：指定用户
  

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

复制代码

(3)首次启动：

1. ## 启动MySQL
2. PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqld --console
3. ...

(4)查找暗码及修改暗码：

• 随机暗码在data目录下的hqiogwdt0114.err文件中：wD2q)XQF%*nz
  1. 2020-01-06T12:04:46.034179Z 1 [Note] A temporary password is generated for root@localhost: wD2q)XQF%*nz

  复制代码
• 使用初始暗码登岸MySQL，重新设置新的暗码：
  1. PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysql -u root -p
  2. Enter password: ************
  3. Welcome to the MySQL monitor.  Commands end with ; or \g.

  22. mysql> exit
  23. Bye
  24. PS D:\Program\mysql\mysql-5.7.24-winx64\bin>

• 使用mysqladmin关闭和重新启动MySQL：
  1. PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqladmin -u root shutdown
  2. mysqladmin: connect to server at 'localhost' failed
  3. error: 'Access denied for user 'root'@'localhost' (using password: NO)'
  4. ## 需要密码
  5. PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqladmin -u root shutdown -p
  6. Enter password: ******
  8. ## 重新启动 --console 会输出日志
  9. PS D:\Program\mysql\mysql-5.7.24-winx64\bin> .\mysqld --console

  复制代码

二.安装8.0版本

(1)在解压目录创建配置文件 - my.ini

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

复制代码

(2)创建data文件夹，初始化数据目录：留意有两种选项

• --initialize：默认的安全安装模式，会天生随机初始的root暗码，这种情况下，暗码被标记为过期，第一次登岸进去后需要设置新的暗码
  
• --initialize-insecure：不安全的安装模式，不会root天生暗码，默认为空暗码
  
• --user：指定用户
  
• 参考官网的文档 - 2.10.1 Initializing the Data Directory
  

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

复制代码

(3)首次启动：

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

复制代码

(4)初次登岸及修改暗码：

• 查察data目录下的hqiogwdt0114.err文件：提示现在使用默认的空暗码
  1. 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.

  复制代码

　　启动8.0 服务　　mysqld install MySQL80 --defaults-file="D:\DevelopTool\MySQL\mysql-5.7.42\my.ini"　　开启服务(管理员打开的cmd窗口开启服务)　　mysqld --install mysql88 --defaults-file="E:\mysql-8.0.39-winx64\mysql-8.0.39-winx64\my.ini"  

• 使用空暗码登岸MySQL，重新设置新的暗码：
  

  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。
  

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