What are the steps for MySQL8.0.32 installation and environment configuration?
一、安装MySQL
下载MySQL的社区版的压缩包:
https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.32-winx64.zip
将压缩包解压到你要安装的目录中
将对应的安装路径添加到环境变量中的path变量中:
xxx\mysql-8.0.32-winx64\bin
此时先看看安装目录mysql-8.0.32-winx64下是否有my.ini文件,即Mysql的配置文件,如果没有,则需要配置。
1)先创建一个my.ini文件
2)添加以下配置
[mysqld] # 设置3306端口 port=3306 # 设置mysql的安装目录加 \data basedir=D:\\software\\mysql-8.0.32-winx64\\data # 设置mysql数据库的数据的存放目录,在安装mysql-5.7.30-winx64.zip版本的时候,此配置不可添加,否则mysql将无法启动。 # datadir=D:\software\mysql-8.0.32-winx64\data # 允许最大连接数 max_connections=200 # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统 max_connect_errors=10 # 服务端使用的字符集默认为UTF8 character-set-server=utf8 # 创建新表时将使用的默认存储引擎 default-storage-engine=INNODB # 默认使用“mysql_native_password”插件认证 default_authentication_plugin=mysql_native_password # 关闭ssl skip_ssl # 配置时区 default-time_zone='+8:00' [mysql] # 设置mysql客户端默认字符集 default-character-set=utf8 [client] # 设置mysql客户端连接服务端时默认使用的端口 port=3306 default-character-set=utf8
5.在搜索框输入cmd,然后以管理员身份运行。
6.然后在命令行中进入到安装目录的bin目录下:
1)先切换D:D:
2)再进入bin目录:cd xxx\mysql-8.0.32-winx64\bin
7.然后下载mysqld:mysqld --install
8.然后初始化mysql,此时会出现:mysqld --initialize --console
此时会出现一个初始密码,需要使用它来修改密码。
9.启动mysql服务:net start mysql
10.进入mysql服务:
1)输入mysql -u root -p
回车
2)将刚刚的初始密码粘贴,然后回车
11.设置密码:ALTER USER'root'@'localhost'IDENTIFIED BY '123456';
12.测试可视化工具navicat
二、错误集
1. 如果操作失误,可以重新安装
在命令行输入:
mysqld remove
即移除mysqld在安装目录中将data文件夹删除即可。
