7 查看已安装资源

rpm -qa | grep mysql

8 初始化

mysqld --initialize 初始化
chown mysql:mysql /var/lib/mysql -R 授权
systemctl start mysqld 开启mysql服务
systemctl status mysqld 查看mysql 状态

cat /var/log/mysqld.log | grep password 查看root初始密码

10 使用root用户登录mysql ,并修改root用户密码

mysql -u root -p #回车之后输入前面的初始密码也就是 Iv7fjuP,ucH+（填自己的密码）

ALTER USER "root"@"localhost" IDENTIFIED BY "自己的密码";
FLUSH PRIVILEGES; #立即生效

再次用户root 用户登录输入自己刚刚修改的密码就可以了

11 远程连接

use mysql;
update user set host = '%' where user ='root'; 
ALTER USER 'root'@'%' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER; #更改加密方式
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '自己的密码'; #更新用户密码 （我这里为root ）
