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;
