Was stimmt nicht mit meinem my.cnf

[webmaster2208]

Hallo Leute,

in einem anderen Thread hatte ich mir versucht Hilfe zu holen wegen meinem lahmen MySQL. Nachdem ich das ganze versucht habe mit tuning-primer.sh zu "optimieren" ist alles noch viel schlimmer und bitte daher um erneut um Hilfe. Irgendwas muss ich da verbockt haben. Vor meiner "Optimierung" war die Response Zeit unter 2s im Schnitt. Jetzt bin ich bei über 10s. Der Server ist pro Stunde für min. 5 Minuten nicht zu erreichen. Ich beziehe mich da auf die Daten von pingdom.com. Siehe Anlagen.
Mittlerweile werden beim einkaufen über paypal schon nicht mehr die Einträge geschafft. Die fehlen oder sind nur halb. So schlimm ist es schon und daher muss ich euch bitten.....bitte, bitte schaut euch die files an. Ich weiss nicht was das Problem ist.

Hier ist meine my.cnf.

# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.

tuning-primer.sh Auswertung derzeit. Ich weiss Server muss min. 48 Stunden laufen, aber eben musste SQL neustarten. Ging nicht anders.

MySQL Version 5.1.72-2 i486

Uptime = 0 days 2 hrs 0 min 56 sec
Avg. qps = 10
Total Questions = 74057
Threads Connected = 4

Warning: Server has not been running for at least 48hrs.
It may not be safe to use these recommendations

runtime variables effects performance visit:

for info about MySQL's Enterprise Monitoring and Advisory Service

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 78 out of 74078 that take longer than 10.000000 sec. to complete
Your long_query_time seems to be fine

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/5.1/en/point-in-time-recovery.html

WORKER THREADS
Current thread_cache_size = 8
Current threads_cached = 6
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 50
Current threads_connected = 4
Historic max_used_connections = 18
The number of used connections is 36% of the configured maximum.
Your max_connections variable seems to be fine.

INNODB STATUS
Current InnoDB index space = 3 M
Current InnoDB data space = 4 M
Current InnoDB buffer pool free = 0 %
Current innodb_buffer_pool_size = 2 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 159 M
Configured Max Per-thread Buffers : 346 M
Configured Max Global Buffers : 34 M
Configured Max Memory Limit : 381 M
Physical Memory : 6.00 G
Max memory limit seem to be within acceptable norms

KEY BUFFER
Current MyISAM index space = 22 M
Current key_buffer_size = 16 M
Key cache miss rate is 1 : 192980
Key buffer free ratio = 82 %
Your key_buffer_size seems to be too high.
Perhaps you can use these resources elsewhere

QUERY CACHE
Query cache is enabled
Current query_cache_size = 16 M
Current query_cache_used = 2 M
Current query_cache_limit = 1 M
Current Query cache Memory fill ratio = 13.34 %
Current query_cache_min_res_unit = 4 K
Your query_cache_size seems to be too high.
Perhaps you can use these resources elsewhere
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 256 K
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 516.00 K
You have had 1420 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 = 4172 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_open_cache = 2056 tables
Current table_definition_cache = 2056 tables
You have a total of 1238 tables
You have 1308 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 16 M
Of 3719 temp tables, 19% were created on disk
Created disk tmp tables ratio seems fine

TABLE SCANS
Current read_buffer_size = 4 M
Current table scan ratio = 12303 : 1
read_buffer_size seems to be fine

TABLE LOCKING
Current Lock Wait ratio = 1 : 106
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'.

Hilft das auch nicht, solltest du jemanden damit beauftragen, sich um den verwendeten Code zu kümmern, da dann höchst wahrscheinlich damit ein Problem besteht.

 

[webmaster2208]

Jetzt hab ich das mal gemacht. Da sind natürlich einige Werte, deutlich höher als ich das gemacht hatte. Ich hoffe das es mit den timout zusammen was bringt. Ich werde das jetzt erstmal beobachten und dann Feedback geben.

Im Moment bekomme ich noch paar Warnungen, dass ich die Werte nicht so hoch setzen sollte.

SLOW QUERIES
The slow query log is NOT enabled.
Current long_query_time = 10.000000 sec.
You have 0 out of 7752 that take longer than 10.000000 sec. to complete
Your long_query_time seems to be fine

BINARY UPDATE LOG
The binary update log is NOT enabled.
You will not be able to do point in time recovery

Historic threads_per_sec = 0
Your thread_cache_size is fine

MAX CONNECTIONS
Current max_connections = 100
Current threads_connected = 6
Historic max_used_connections = 6
The number of used connections is 6% 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

INNODB STATUS
Current InnoDB index space = 3 M
Current InnoDB data space = 4 M
Current InnoDB buffer pool free = 0 %
Current innodb_buffer_pool_size = 2 M
Depending on how much space your innodb indexes take up it may be safe
to increase this value to up to 2 / 3 of total system memory

MEMORY USAGE
Max Memory Ever Allocated : 288 M
Configured Max Per-thread Buffers : 4.11 G
Configured Max Global Buffers : 34 M
Configured Max Memory Limit : 4.15 G
Physical Memory : 6.00 G
Max memory limit seem to be within acceptable norms

Current Query cache Memory fill ratio = 4.27 %
Current query_cache_min_res_unit = 4 K
Your query_cache_size seems to be too high.
Perhaps you can use these resources elsewhere
MySQL won't cache query results that are larger than query_cache_limit in size

SORT OPERATIONS
Current sort_buffer_size = 2 M
Current read_rnd_buffer_size = 16 M
Sort buffer seems to be fine

JOINS
Current join_buffer_size = 8.00 M
You have had 60 queries where a join could not use an index properly
join_buffer_size >= 4 M
This is not advised
You should enable "log-queries-not-using-indexes"
Then look for non indexed joins in the slow query log.

OPEN FILES LIMIT
Current open_files_limit = 4206 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_open_cache = 2048 tables
Current table_definition_cache = 2048 tables
You have a total of 1238 tables
You have 1247 open tables.
The table_cache value seems to be fine

TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 16 M
Of 709 temp tables, 31% were created on disk
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
Current read_buffer_size = 16 M
Current table scan ratio = 3328 : 1
read_buffer_size is over 8 MB there is probably no need for such a large read_b
ffer

TABLE LOCKING
Current Lock Wait ratio = 1 : 1221
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'.

Das sieht aber nicht nach meinen Einstellungen aus? join_buffer_size ist nicht die von mir angegebene, genauso wenig wie bspw. innodb_buffer_pool_size oder query_cache_size. Das sollte überprüft werden. Zudem kann man noch concurrent_insert=2 unter [mysqld] hinzufügen.

Ich hab mir angeschaut was du verändert hast und hab dann copy Paste gemacht.

Hab jetzt auch mal oben verglichen und das ist genau das was du gepostet hast.
join_buffer_size war vorher 516K und ist jetzt 8M.
Innodb_buffer_pool_size war 2M und du hast auch 2M gelassen.
Query_cache_size hat sich nicht auf 128M verändert. Warum auch immer.

Diese my.cnf befindet sich in /etc. Ich hab noch eine in /etc/mysql soll ich die auch mal komplett ändern?

Concurrent_insert werd ich machen. Ich wusste nicht was es bewirken kann, daher hab ich die Finger von gelassen.

 

[webmaster2208]

Hab jetzt auch die my.cnf in /etc/mysql abgeändert. Nun wurden die Daten übernommen.

Sieht alles bestens aus. Wenn die CPU-Last, die MySQLd verursacht, nun immer noch zu hoch ist, muss an der Anwendung gearbeitet werden und nicht an der my.cnf.
