安装说明:

操作记录

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;
