Mysql makes use of storage engines for storage as well as efficient management of data within the database. One such is InnoDB storage engine which further makes use of ibdata1 file for the purpose of data storage. But if this particular file gets damaged due to any reasons, you lose access to all your database records and errors including ‘Timeout error occurred trying to start MySQL Daemon’ appears on the screen.
Lets assume a situation practically where you faced unexpected system shutdown and when tried to recover InnoDB database after this:
“Timeout error occurred trying to start MySQL Daemon. Starting MySQL: [FAILED]"
Below mentioned entries are encountered in the Application Event Log of Mysql:
“100317 21:53:25 mysqld started
100317 21:53:25 InnoDB: Error: page 1 log sequence number 0 69585642
InnoDB: is in the future! Current system log sequence number 0 15520.
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files. See
InnoDB: for more information.
InnoDB: Database page corruption on disk or a failed
InnoDB: file read of page 2.
InnoDB: You may have to recover from a backup.
100317 21:53:25 InnoDB: Page dump in ASCII and hex (16384 bytes)"
The foremost reason behind the above encountered Mysql error is the ‘ibdata1’ file corruption occurred due to reasons like virus attack, OS malfunction, sudden PC shutdown or any kind of user errors.
In order to fix the timeout error occurred trying to start mysql daemon starting mysql failed server, then use an updated backup to restore the lost or inaccessible data. In case of inavailability of backup, make use of mysql inbuilt commands freely provided to repair the corrupt or damaged ibdata1 file.In other case, the beneficial option would be to go for mysql repair tool which is especially meant to repair almost every corrrupted object of Mysql database after which you can have access to your database records with ease.
