依次执行如下命令进行安装

rpm -ivh mysql-community-common-8.0.23-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-libs-8.0.23-1.el7.x86_64.rpm --nodeps --force
rpm -ivh mysql-community-server-8.0.23-1.el7.x86_64.rpm --nodeps --force

执行如下命令初始化数据库:

mysqld --initialize;
chown mysql:mysql /var/lib/mysql -R;
systemctl start mysqld.service;
systemctl  enable mysqld;

可能遇到如下异常
mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决方案:执行如下命令安装 yum install -y libaio

初始化完成以后会生成一个临时密码

使用默认生成的密码，登录数据库修改成新密码

mysql -uroot -p

修改本机root账户登录密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root666';

在这里插入图片描述
设置root账户远程访问

mysql> create user 'root'@'%' identified with mysql_native_password by 'pwd123456';
Query OK, 0 rows affected (0.02 sec)

mysql> grant all privileges on *.* to 'root'@'%' with grant option;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql> exit;
