This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_
read_buffer_
max_used_
max_threads=151
thread_count=1
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went

information that should help you find out what is causing the crash.
Installation of system tables failed! Examine the logs in
/var/lib/mysql for more information.
You can try to start the mysqld daemon with:
shell> /usr/sbin/mysqld --skip-grant &
and use the command line tool /usr/bin/mysql
to connect to the mysql database and look at the grant tables:
shell> /usr/bin/mysql -u root mysql
mysql> show tables
Try 'mysqld --help' if you have problems with paths. Using --log
gives you a log in /var/lib/mysql that may be helpful.
Please consult the MySQL manual section
'Problems running mysql_install_db', and the manual section that
describes problems on your OS. Another information source are the
MySQL email archives available at http://
Please check all of the above before mailing us! And remember, if
you do mail us, you MUST use the /usr/bin/mysqlbug script!
Percona Server is distributed with several useful UDF (User Defined Function) from Maatkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h host.domain password 'new-password'
Alternatively you can run:
/usr/bin/
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!
