mkdir mysql 40 ll 41 cd my 42 cd mysql/ 43 ll 45 tar -xvf mysql-8.0.19-1.el7.x86_64.rpm-bundle.tar 46 ll 47 rpm -ivh mysql-community-common-8.0.19-1.el7.x86_64.rpm --nodeps --force 48 rpm -ivh mysql-community-libs-8.0.19-1.el7.x86_64.rpm --nodeps --force 49 rpm -ivh mysql-community-client-8.0.19-1.el7.x86_64.rpm --nodeps --force 50 rpm -ivh mysql-community-server-8.0.19-1.el7.x86_64.rpm --nodeps --force 51 rpm -qa | grep mysql 52 mysqld --initialize; 53 chown mysql:mysql /var/lib/mysql -R; 54 systemctl start mysqld.service; 55 systemctl enable mysqld; 56 cat /var/log/mysqld.log | grep password 57 mysql -uroot -p 58 systemctl stop firewalld.service; 59 systemctl disable firewalld.service; 60 systemctl mask firewalld.service; 61 ifconfig
通过 cat /var/log/mysqld.log | grep password 命令查看数据库的密码
通过 mysql -uroot -p 敲回车键进入数据库登陆界面
通过 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root'; 命令来修改密码
通过 exit; 命令退出 MySQL，然后通过新密码再次登陆
.通过以下命令，进行远程访问的授权
create user 'root'@'%' identified with mysql_native_password by 'root'; grant all privileges on *.* to 'root'@'%' with grant option; flush privileges;
通过 ALTER USER 'root'@'localhost' IDENTIFIED BY 'root' PASSWORD EXPIRE NEVER;
命令修改加密规则，MySql8.0 版本 和 5.0 的加密规则不一样，而现在的可视化工具只支持旧的加密方式。
通过 flush privileges; 命令刷新修该后的权限
通过以下命令，关闭 firewall(防火墙）
systemctl stop firewalld.service; systemctl disable firewalld.service; systemctl mask firewalld.service;
