In Percona 5.7, the temporary password is stored in /var/log/mysqld.log so you can find it by:
grep 'temporary password' /var/log/mysqld.log
After that, you can start mysql
sudo systemctl start mysql
sudo /usr/bin/mysql_secure_installation
and use your temporary password to use.
stop mysql service
systemctl stop mysqld
view mysql status
systemctl status mysqld
using the new amysql 5.7
use mysql;
select user,host from user;
drop user 'root'@'localhost';
CREATE USER 'admin'@'%' IDENTIFIED BY 'you password';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' IDENTIFIED BY 'you password';
FLUSH PRIVILEGES;
