wget然後進行repo的安裝
rpm -ivh mysql57-community-release-el7-9.noarch.rpm2、安裝mysql使用yum命令即可完成安裝執行完成後會在
/etc/yum.repos.d/目錄下生成兩個repo檔案mysql-community.repomysql-community-source.repo
yum install mysql-server3、啟動msyql：
systemctl start mysqld4、配置mysql
獲取安裝時的臨時密碼：
grep 'temporary password' /var/log/mysqld.log5、登入：
mysql -u root -p登入成功後修改密碼：
這裡的密碼是g6=tz(?qdgy
使用預設的密碼登陸
mysql -uroot -p
alter user 'root'@'localhost' identified by 'root';
如果密碼設定太簡單出現以下的提示
首先，修改validate_password_policy引數的值
mysql> set global validate_password_policy=0;
再修改密碼的長度
set global validate_password_length=1;
再次執行修改密碼就可以了
alter user 'root'@'localhost' identified by 'root';
grant all privileges on *.* to 'root'@'%' identified by 'mypassword' with grant option;
flush privileges;
