| | 563 | Examine the logs in /var/log/percona-server for more information. You can |
| | 564 | also try to start the mysqld daemon with: |
| | 565 | |
| | 566 | /usr/sbin/mysqld --skip-grant & |
| | 567 | |
| | 568 | You can use the command line tool mysql to connect to the mysql |
| | 569 | database and look at the grant tables: |
| | 570 | |
| | 571 | shell> mysql -u mysql mysql |
| | 572 | mysql> show tables |
| | 573 | |
| | 574 | Try 'mysqld --help' if you have problems with paths. Setting on |
| | 575 | logging in $MYSQL_DATA_DIR/percona-serverd.conf gives you a log in /var/log/percona-server/query.log that |
| | 576 | may be helpful. The latest information about percona-server is available on the |
| | 577 | web at https://www.percona.com/software/mysql-database/percona-server. |

| | 579 | Please check PLD Linux ftp site for newer versions of this package. |
| | 580 | |
| | 581 | Please consult the percona-server manual section: 'Problems running |
| | 582 | mysql_install_db', and the manual section that describes problems on |
| | 583 | your OS. Another information source is the percona-server email archive. |
