MySQL5.7加强了root用户的安全性，因此在第一次安装后会初始化一个随机密码，以下为查看初始随机密码的方式
grep 'temporary password' /var/log/mysqld.log
登录mysql mysql -u root -pSET PASSWORD = PASSWORD('你的密码');
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
flush privileges;
然后退出后即可用新密码登录。
远程连接授权：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你的密码' WITH GRANT OPTION;systemctl start mysqld.service
systemctl stop mysqld.service
systemctl restart mysqld.service
systemctl enable mysqld.servicesystemctl start mariadb.service支持表情数据库
