MySQL安装之CentOS 7下使用rpm包安装8.0版本

  一、删除已有mysql

rpm -qa | grep mysql  查找是否存在已安装的mysql
yum remove mysql-community-common-x.x.xx-1.el7.x86_64  如果找到,则依次卸载全部安装包
find / -name *mysql*  查找mysql的残余文件
rm -rf /usr/lib64/mysql  如果找到,则依次删除所有残余文件

  二、安装mysql服务

  1、下载地址:https://downloads.mysql.com/archives/community/,本文选择8.0.20,依次下载、安装如下文件

rpm -ivh mysql-community-common-8.0.20-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-8.0.20-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.20-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.20-1.el7.x86_64.rpm

  2、启动mysql服务

systemctl start mysqld

  3、查看临时密码

cat /var/log/mysqld.log | grep password

  4、使用临时密码登录

mysql -uroot -p

  5、修改临时密码为自己指定密码

alter user 'root'@'localhost' identified by 'shenL1234!';

  6、创建远程访问用户和密码、并赋予权限

create user 'root'@'%' identified with mysql_native_password by 'shenL1234!';  创建用户并指定密码
grant all privileges on *.* to 'root'@'%' with grant option;  授权
flush privileges;  刷新权限
