1.解压

tar -xvf mysql-8.0.28-1.el8.aarch64.rpm-bundle.tar

2.安装必须软件（务必根据顺序)

rpm -ivh mysql-community-common-8.0.28-1.el8.aarch64.rpmrpm -ivh mysql-community-client-plugins-8.0.28-1.el8.aarch64.rpmrpm -ivh mysql-community-libs-8.0.28-1.el8.aarch64.rpmrpm -ivh mysql-community-client-8.0.28-1.el8.aarch64.rpmrpm -ivh mysql-community-icu-data-files-8.0.28-1.el8.aarch64.rpmrpm -ivh mysql-community-server-8.0.28-1.el8.aarch64.rpm

3.修改配置文件

vim /etc/my.cnf

在末尾补一行：

lower_case_table_names=1//1：数据库大小写不敏感//0：数据库大小写敏感

4.初始化数据库

mysqld --initialize --console

5.目录授权

chown -R mysql:mysql /var/lib/mysql/

6.启动mysql服务

systemctl start mysqld

7.编辑下环境变量

vim /etc/profile

末尾加上一行：

export PATH=$PATH:/usr/bin/mysq

8.查看临时密码

cat /var/log/mysqld.log

9.用临时密码登录

mysql -u root -p

10.修改密码

alter USER 'root'@'localhost' IDENTIFIED BY '123456';//红色设置自己的密码

navicat远程连接报错

1251 client does not support authentication protocol requested by server;consider upgrading Mysql client

ERROR 1396 (HY000): Operation ALTER USER failed for ‘root’@’localhost’

先登录mysql

mysql -u root -p//输入密码mysql> use mysql;mysql> select user,host from user;

你可能执行的是:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123';

改成:

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123';

如果还是不行：

尝试一：重置密码为空

先登录MySQL，重置密码为空，并刷新

  1. update user set authentication_string='' where user='root';

  2. flush privileges;

再用上面的方法修改密码

navicat远程连接报错

Authentication plugin ‘caching_sha2_password‘ cannot be loaded…

1、登录Mysql：

mysql -u root -p

2、修改账户密码加密规则并更新用户密码：

//修改加密规则（可以直接复制）

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘password’ PASSWORD EXPIRE NEVER;

//更新一下用户的密码（可以直接复制）

ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’;

3、刷新权限并重置密码

//刷新权限（可以直接复制）

FLUSH PRIVILEGES;

4、重置密码

//此处请自定义密码，红色的root就是博主自定义的密码

alter user ‘root’@’localhost’ identified by ‘root’;

此处将密码改为root

5、重新打开软件，再次连接数据库即可
