mysql-8.0.11-winx64环境搭建

1. 搜索mysql

2. 下载，点击

3. 解压后进入bin目录D:programmysql-8.0.11-winx64in

4. 配置 my.imi文件，D:programmysql-8.0.11-winx64

[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=D:\program\mysql-8.0.11-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:\program\mysql-8.0.11-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
[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. 初始化数据库生成Data目录和默认密码

mysqld --initialize --console

6. 添加服务

mysqld -install

如果用非管理员执行命令会提示：Install/Remove of the Service Denied

删除服务：mysqld -remove

7. 启动mysql

net start mysql

停止net stop mysql

8. 登录数据库并修改密码

mysql -u root -p

修改root 密码 set password = 新密码;

如果Navicat连接不上，使用mysql_native_password加密规则更新密码
ALTER USER root@localhost IDENTIFIED WITH mysql_native_password BY 123456; 
FLUSH PRIVILEGES; #刷新权限

9. 如果是mysql升级

ERROR 1449 (HY000): The user specified as a definer (mysql.infoschema@localhost) does not exist

需要mysql_upgrade -u root -p

问题：The server time zone value Öйú±ê׼ʱ¼ä is unrecognized or represents more than one time zone....

show variables like %time_zone%;
set global time_zone=+8:00;

Caused by: com.mysql.cj.exceptions.CJException: null, message from server: "Host 192.168.1.102 is not allowed to connect to this MySQL server"

mysql -u root -p
mysql>use mysql;
mysql>update user set host = % where user = root;
mysql>flush privileges;
重启mysql
