 501 and set passwords:
 502
 503 For 'root' user (ALL privileges, DB admin), paste command with new password:
 504 ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';
 505 FLUSH PRIVILEGES;
 506
 507 For 'mysql_sysadmin' (RELOAD, SHUTDOWN and REPLICATION CLIENT privileges):
 508 CREATE USER 'mysql_sysadmin'@'localhost' IDENTIFIED BY 'sysnewpassword' PASSWORD EXPIRE NEVER;
 509 GRANT RELOAD, SHUTDOWN, REPLICATION CLIENT ON *.* TO 'mysql_sysadmin'@'localhost';
 510 FLUSH PRIVILEGES;
 511
 512
 513 Both into command:
 514 $ mysql -u root -p --ssl-mode=disabled -S $MYSQL_SOCKET
 515
 516 NOTE:

 531 Examine the logs in $MYSQL_ERRLOG for more information. You can
 532 also try to start the mysqld daemon with:
 533
 534 @mysqlsbindir@/mysqld --skip-grant &
 535
 536 You can use the command line tool mysql to connect to the mysql
 537 database and look at the grant tables:
 538
 539 shell> mysql -u root mysql
 540 mysql> show tables
 541
 542 Try 'mysqld --help' if you have problems with paths. Setting on
 543 logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in
 544 /var/log/mysql/@mysqlversion/query.log that may be helpful.
 545 The latest information about MySQL is available on the web at
 546 http://www.mysql.com/.
 547
 548 Please check TLD Linux site for newer versions of this package.
 549
 550 Please consult the MySQL manual section: 'Problems running
 551 mysql_install_db', and the manual section that describes problems on
 552 your OS. Another information source is the MySQL email archive.
