记录:CentOS安装配置MySQL8

rpm -qa|grep mariadb

如果有,卸载

yum rm mariadb

卸载后还需要删除残留文件夹,因为我没有MariaDB,这里不做展示,可以用如下命令搜索

find / -name mysql

MySQL直接用yum安装的话是不行的,启动服务时会提示unit mysqld.service not found,需要先安装MySQL官方的rpm包

Index of /232905https://repo.mysql.com/进去找一个你想要的版本,比如我装的是,包名对应改掉

wget http://repo.mysql.com/mysql80-community-release-el8.rpm
rpm -ivh mysql80-community-release-el8.rpm
yum install mysql mysql-server mysql-devel -y

启动服务

systemctl start mysqld

启动MySQL

mysql

启动成功咋安装完毕

MySQL第一次进入是没有密码的,设置密码

alter user 'root'@'localhost' identified by '新密码';

5.7版本(以用户名为root,密码为admin为例)

grant all privileges on *.* to 'root'@'%' identified by 'admin' with grant option;

flush privileges;

8.0版本

use mysql;
update user set host = '%' where user = 'root';

flush privileges;
