For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3308 socket =/home/mysqlserver/62/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] port = 3308 socket =/home/mysqlserver/62/mysql.sock skip-external-locking key_buffer_size = 512M max_allowed_packet = 16M table_open_cache = 512 sort_buffer_size = 2M read_buffer_size = 2M read_rnd_buffer_size = 16M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size = 256M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 32 #innodb_force_recovery = 3 #innodb_purge_thread = 0 max_connections=50 skip-name-resolve log_bin_trust_function_creators=1 event_scheduler=1 innodb_buffer_pool_size = 3024M expire_logs_days=5 log-error=/home/mysqlserver/62/localhost.err datadir=/home/mysqlserver/62 pid-file=/home/mysqlserver/62/localhost.pid binlog-do-db=game2010002 binlog-do-db=game2010002_1 binlog-do-db=game2010002_2 binlog-do-db=game2010002_3 binlog-do-db=game2010002_4 binlog-do-db=game2010002_5 binlog-do-db=game2010002_6 binlog-do-db=game2010002_7 binlog-do-db=game2010002_8 binlog-do-db=game2010002log binlog-ignore-db=mysql binlog-ignore-db=test # Don't listen on a TCP/IP port at all.

However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3308 #master-port = <port> # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # # binary logging format - mixed recommended #binlog_format=mixed # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir =/home/mysqlserver/62server/mysql #innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend #innodb_log_group_home_dir =/home/mysqlserver/62server/mysql # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 384M #innodb_additional_mem_pool_size = 20M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 256M innodb_log_buffer_size = 64M innodb_flush_log_at_trx_commit = 2 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 256M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout

Thank you for the report. Could you please send us full error log file, including records prior last crash after you tried to start the server.

Thank you for the feedback. I see your error log file is full of entries: 2013-05-25 10:21:50 7fafdda26700 InnoDB: Assertion failure in thread 140393314412288 in file btr0cur.cc line 283 InnoDB: Failing assertion: btr_page_get_next(get_block->frame, mtr) == page_get_page_no(page) which started occurring since April, 20. These assertions look like table corruption. Could you please check which tables affected and which queries cause the assertion. You can try one of three and half following approaches. 1. Turn ON possibility to write core files. This can be done if you add option core to the my.cnf and adjust OS settings, so it allows user which runs mysqld to create core files of unlimited size. 2. Turn ON general query log, wait when crash occur again and send us general log together with error log. Or do research yourself: find time when server crashed and find list of transactions which were executed during that time. 2.5. In addition to 2. Turn ON InnoDB Monitor, so it will write current running transactions into error log file. 3. Run CHECK TABLE on every InnoDB table you have, so we can identify which is corrupted. Note, server will crash if it finds a problem.
