MySQL在windows下相关的安装和配置操作,多个MySQL的安装详细教程

我的博客介绍了大部分安装教程

https://blog.csdn.net/m0_37520980/article/details/80353315

当一台计算机安装多个MySQL的时候就需要一些下面的配置

mysqld --install [服务名] //这里可以设置服务名

重新解释一下安装的操作各个含义

D:\Program Files\mysql-8.0.11>cd bin     //切换到bin目录下

D:\Program Files\mysql-8.0.11\bin>mysqld --remove //我以前安装过mysql，先移除
Service successfully removed.

D:\Program Files\mysql-8.0.11\bin>mysqld --install    //安装mysql，注意这里都是两个小横线
Service successfully installed.
D:\Program Files\mysql-8.0.11\bin>mysqld --install mysql5.6//这里可以设置服务名
设置服务名在一个机器安装多个MySQL服务时可以用到,建议服务名全部用小写,否则服务无法启动


D:\Program Files\mysql-8.0.11\bin>mysqld --initialize --console    //注意这里会生成一个密码
//在mysql5.6版本时,此步骤不能要,否则服务无法启动,

在安装了mysql 8.0.11之后又安装了mysql 5.6,现在我们再装一个MySQL 5.7

记录一下过程

首先去官网下载 ----> 解压配置环境变量 ------> 然后新建data文件夹---->新建my.ini

注意修改一下端口我的修改成如下的样子

[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8

[mysqld]
#设置3308端口,由于以前使用了3306和3307了,现在使用3308
port = 3308

# 设置mysql的安装目录，根据自己目录修改
basedir=D:\Program Files\mysql-5.7.23

# 设置mysql数据库的数据的存放目录
datadir=D:\Program Files\mysql-5.7.23\data

# 允许最大连接数
max_connections=1000

# 服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8

# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
###下面的这些配置我没用####
#忘记密码时使用
#skip-grant-tables
#设置协议认证方式
#default_authentication_plugin=mysql_native_password

然后就是一通安装服务初始化数据库

D:\Program Files\mysql-5.7.23\bin>mysql -h localhost -P3308 -uroot -p
Enter password: ************
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)

发现无法连接!!!

找了一会原因,发现服务有问题

发现5.6和5.7的路径竟然是一样的,果断删除服务

D:\Program Files\mysql-5.7.23\bin>net stop mysql5.7
mysql5.7 服务正在停止.
mysql5.7 服务已成功停止。


D:\Program Files\mysql-5.7.23\bin>mysqld --remove mysql5.7
Service successfully removed.

修改环境变量

path中将5.7的环境变量移到前面,

然后以管理身份重新打开一个命令窗口！！！

安装服务

C:\windows\system32>D:

D:\>cd D:\Program Files\mysql-5.7.23\bin

D:\Program Files\mysql-5.7.23\bin>mysqld --install mysql5.7
Service successfully installed.

查看服务正常

删除5.7路径下data目录中的所有内容（不删除直接启动服务也是可以的）

C:\windows\system32>D:

D:\>cd D:\Program Files\mysql-5.7.23\bin

D:\Program Files\mysql-5.7.23\bin>mysqld --install mysql5.7
Service successfully installed.

//初始化数据库，如果没有删除data文件夹可以不用初始化，直接启动服务即可
D:\Program Files\mysql-5.7.23\bin>mysqld --initialize --console

//指定端口链接数据库

Enter password: ************   //这里是密码，博客中解释过了，如果没有重新初始化就是上一个密码

//修改密码，两步，还有一个刷新权限

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

至此，数据库安装完成。

效果，三个版本的数据库都启动成功，各自占用不同的端口
