#初始化数据库，初始化失败可能会提示缺少包，缺少下载以下的包
mysqld --initialize;
#下载缺少银河麒麟V10缺少的包并安装（银河麒麟基本都缺这个包，且官方镜像没有）
wget https://mirrors.sohu.com/centos/8/AppStream/aarch64/os/Packages/compat-openssl10-1.0.2o-3.el8.aarch64.rpm
rpm -ivh compat-openssl10-1.0.2o-3.el8.aarch64.rpm
#给对应文件夹授权
chmod -R 777 /var/lib/mysql
#后面就是启动数据库和数据库配置

开启远程登录

1.登录MySQL执行以下命令

mysql>use mysql;#选择MySQL用户表
mysql>update user set host = '%' where user = 'root';#把本地登录localhost改为%
mysql>select host, user, plugin from user;#查询修改是否成功

这里需要修改才可以远程访问

update user set plugin = 'mysql_native_password' where user = 'root';

修改修改后再修改一下密码

mysql> use mysql; #选择用户表
mysql> update user set authentication_string='' where user='root';#将字段置为空
mysql> flush privileges ;
ALTER user 'root'@'%' IDENTIFIED BY '123456';#把root和%的修改密码改为123456
mysql> quit;

执行ALTER user ‘root’@’%’ IDENTIFIED BY '123456’主要是把%的密码改为123456
