Breuchte mal Hilfe bei mysql =)

[Tyjo]

Hallo zusammen... wie ihr seht bin ich noch Neu hier aber bisher konnte mir noch niemand in anderen Foren so wirklich helfen...
breuchte am besten ne fertig optimierte config für mysql aber irgendwie wissen in den anderen Foren nichtmals was mein Problem ist=)

Also ich fang mal an... Wir betreiben mehrere Gameserver für Trackmania...
Dort wird ein programm namens Aseco verwendet damit werden alle Rekorde etc in mysql abgespeichert und es spielen durchschnittlich ca 150man auf den servern
"Aseco" verwendet unter anderem php dateien und somit halt viel mit mysql...

Eckdaten: AMD 2.6 ghz , 2gb ddr2 ram

Also hier einmal meine ausgabe aus der tuning-primer.sh

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10 sec.
You have 0 out of 2915667 that take longer than 10 sec. to complete
Your long_query_time may be too high, I typically set this under 5 sec.

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery
See http://dev.mysql.com/doc/refman/5.0/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 1
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 8
Historic max_used_connections = 9
The number of used connections is 9% of the configured maximum.
You are using less than 10% of your configured max_connections.
Lowering max_connections could help to avoid an over-allocation of memory
See "MEMORY USAGE" section to make sure you are not over-allocating

./tuning-primer.sh: line 350: bc: command not found

Max memory limit seem to be within acceptable norms

KEY BUFFER
./tuning-primer.sh: line 668: bc: command not found
./tuning-primer.sh: line 669: bc: command not found
./tuning-primer.sh: line 350: bc: command not found
Current MyISAM index space =  M
./tuning-primer.sh: line 350: bc: command not found
Current key_buffer_size =  M
Key cache miss rate is 1 : 3700
Key buffer free ratio =  %
./tuning-primer.sh: line 706: [: -le: unary operator expected
./tuning-primer.sh: line 710: [: -le: unary operator expected
Your key_buffer_size seems to be fine

QUERY CACHE
./tuning-primer.sh: line 741: bc: command not found
./tuning-primer.sh: line 742: bc: command not found
Query cache is enabled
./tuning-primer.sh: line 350: bc: command not found

./tuning-primer.sh: line 756: bc: command not found
./tuning-primer.sh: line 757: [: -gt: unary operator expected
./tuning-primer.sh: line 764: [: -le: unary operator expected
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
./tuning-primer.sh: line 350: bc: command not found
Current sort_buffer_size =  M
./tuning-primer.sh: line 350: bc: command not found
Current read_rnd_buffer_size =  K
Sort buffer seems to be fine

JOINS
./tuning-primer.sh: line 350: bc: command not found
Current join_buffer_size =  K
You have had 34080 queries where a join could not use an index properly
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.
If you are unable to optimize your queries you may want to increase your
join_buffer_size to accommodate larger joins in one pass.

Note! This script will still suggest raising the join_buffer_size when
ANY joins not using indexes are found.

OPEN FILES LIMIT
Current open_files_limit = 1024 files
The open_files_limit should typically be set to at least 2x-3x
that of table_cache if you have heavy MyISAM usage.
Your open_files_limit value seems to be fine

TABLE CACHE
Current table_cache value = 64 tables
You have a total of 266 tables
You have 64 open tables.
Current table_cache hit rate is 2%, while 100% of your table cache is in use
You should probably increase your table_cache

TEMP TABLES
./tuning-primer.sh: line 350: bc: command not found
Current max_heap_table_size =  M
./tuning-primer.sh: line 350: bc: command not found
Current tmp_table_size =  M
Of 4733 temp tables, 27% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Perhaps you should increase your tmp_table_size and/or max_heap_table_size
to reduce the number of disk-based temporary tables
Note! BLOB and TEXT columns are not allow in memory tables.
If you are using these columns raising these values might not impact your
ratio of on disk temp tables.

TABLE SCANS
./tuning-primer.sh: line 350: bc: command not found
Current read_buffer_size =  K
Current table scan ratio = 22165 : 1
You have a high ratio of sequential access requests to SELECTs
You may benefit from raising read_buffer_size and/or improving your use of indexes.

TABLE LOCKING
Current Lock Wait ratio = 1 : 2010
You may benefit from selective use of InnoDB.
If you have long running SELECT's against MyISAM tables and perform
frequent updates consider setting 'low_priority_updates=1'
If you have a high concurrency of inserts on Dynamic row-length tables
consider setting 'concurrent_insert=2'.

Verstehen tuh ich da nicht viel raus vorallem sehr oft "command not found"

< my.cnf is die standart cnf... kann sie leider net dazu posten is zu lang fürs forum trotz [CODE] >

Is halt die standart cnf.. muss dazu sagen ich arbeite normal nicht mit datenbanken etc....
Mein gebiet sind eher auf gameserver =)

Hoffe unter euch is ein Spezialist der mir paar befehle sagen könnte die ich hinzufügen oder ändern könnte...
Vielleicht hat sogar jemand eine perfekt abgestimmte my.cnf würd mich sehr freuen =)
