安装mysql

tar -xf mysql-8.0.28-1.el7.aarch64.rpm-bundle.tar

rpm -ivh mysql-community-common-8.0.28-1.el7.aarch64.rpm 

rpm -ivh mysql-community-client-plugins-8.0.28-1.el7.aarch64.rpm 

rpm -ivh mysql-community-libs-8.0.28-1.el7.aarch64.rpm 

rpm -ivh mysql-community-client-8.0.28-1.el7.aarch64.rpm 

rpm -ivh mysql-community-icu-data-files-8.0.28-1.el7.aarch64.rpm 

rpm -ivh mysql-community-server-8.0.28-1.el7.aarch64.rpm

初始化启动mysql

mysqld --initialize --console

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

systemctl start mysqld

# 查看初始密码
cat /var/log/mysqld.log |grep root

# 登录修改密码
mysql -uroot -pArqnZ/GjV2eW
alter user 'root'@'localhost' identified by '123456';

设置远程登录

默认是不能远程登录，只能使用localhost或者127.0.0.1。这个必须设置一下

mysql -u root -p123456

use mysql;

select host, user from user;

update user set host = ‘%’ where user = ‘root’;
此时，root用户的权限已经允许非localhost登录

# 刷新设置，即可远程登录
FLUSH PRIVILEGES;
