Uzatmayım... Teşekkürler...
MySQL Root Şifresi Sıfırlamak isminde bi arama yapmak hiç aklıma gelmemişti.. Tesadüf eseri http://alicambaz.blogspot.com/2007_09_01_archive.html Linkinde Buldugum bilgiler çok faydalı oldu... Ve Script Çalıştı... Önce Mysql Sunucusunu Durudruyoruz... Kod:
service mysqld stop Kod:
kill -9 pidno Daha sonra Kod:
mysqld --skip-grant-tables --user=root Daha sonra yeni bir konsol açarak Kod:
mysql -u root Daha sonra Kod:
UPDATE mysql.user SET Password=PASSWORD('yenişifreniziyazın') WHERE User='root';
Kod:
FLUSH PRIVILEGES; Script için tekrar teşekkürler... 2 gün sonra denememizi yaparak sonuçları kontrol edeceğiz... |

Merhaba Arkadaşlar;
Ciddi manada problem yaşıyorum. Memory kullamımı %50lerde geziyor ve aşağıda gördüğünüz gibi akıl almaz load averagelarına ulaşıyor... Yapabileceğiniz en iyi öneriyi yaparsanız çok ama çok memnun olurum son durumu size bildiririm. sistem yaklaşık 4 gündür ayakta... Lütfen ne yapabiliyorsak yapalım ![]() Başka önerileriniz varsa lütfen belirtiniz.. Şimdiden çok teşekkürler..

Alıntı:
MySQL en kötü hali ile yani sıfır konfigürasyon ile dahi hiçbir sorun yaşatmaz. Serverınızdaki load (aşırı yük) sorununun kaynağını MySQL de aramanız yanlıştır. Peki sorun ne o zaman? Bu tür aşırı yüklere genellikle 3 şey neden olur. 1. Hatalı, yanlış yazılmış kod. Örneğin sonsuz döngüler, veritabanında yaratılmamış indexler. 2. Saldırılar 3. Donanım sorunları veya yetersizlği: Fanı sorunlu aşırı ısınan makine, bellek yada hard diskinde hata olan makine, yetersiz bellek yada hard disk yada CPU. - Tüm bunları kontrol etmenizin ardından, web serverinizi optimize edin. - Webserver optimizasyonu ardından PHP yi optimize edin, Xcache vb.. kurun - Ardından veritabanını optimize edin.

-- MYSQL PERFORMANCE TUNING PRIMER --
- By: Matthew Montgomery -
MySQL Version 4.1.22-standard-log i686
Uptime = 7 days 18 hrs 3 min 37 sec
Avg. qps = 18
Total Questions = 12396769
Threads Connected = 3
Server has been running for over 48hrs.
It should be safe to follow these recommendations

runtime variables effects performance visit:

SLOW QUERIES
Current long_query_time = 10 sec.
You have 167 out of 12396798 that take longer than 10 sec. to complete
The slow query log is NOT enabled.
Your long_query_time may be too high, I typically set this under 5 sec.
WORKER THREADS
Current thread_cache_size = 128
Current threads_cached = 112
Current threads_per_sec = 0
Historic threads_per_sec = 0
Your thread_cache_size is fine
MAX CONNECTIONS
Current max_connections = 500
Current threads_connected = 2
Historic max_used_connections = 113
The number of used connections is 22% of the configured maximum.
Your max_connections variable seems to be fine.
MEMORY USAGE
Max Memory Ever Allocated : 1 G
Configured Max Per-thread Buffers : 6 G
Configured Max Global Buffers : 298 M
Configured Max Memory Limit : 6 G
Physical Memory : 3.20 G
Max memory limit exceeds 90% of physical memory
KEY BUFFER
Current MyISAM index space = 102 M
Current key_buffer_size = 256 M
Key cache miss rate is 1 : 4169
Key buffer fill ratio = 30.00 %
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 = 32 M
Current query_cache_used = 26 M
Current query_cache_limit = 4 M
Current Query cache Memory fill ratio = 81.78 %
Current query_cache_min_res_unit = 4 K
Query Cache is 7 % fragmented
Run "FLUSH QUERY CACHE" periodically to defragment the query cache memory
If you have many small queries lower 'query_cache_min_res_unit' to reduce fragme ntation.
However, 1666833 queries have been removed from the query cache due to lack of m emory
Perhaps you should raise query_cache_size
MySQL won't cache query results that are larger than query_cache_limit in size
SORT OPERATIONS
Current sort_buffer_size = 2 M
Current record/read_rnd_buffer_size = 7 M
Sort buffer seems to be fine
JOINS
Current join_buffer_size = 132.00 K
You have had 2213 queries where a join could not use an index properly
You have had 38 joins without keys that check for key usage after each row
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 = 6510 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 = 3000 tables
You have a total of 711 tables
You have 930 open tables.
The table_cache value seems to be fine
TEMP TABLES
Current max_heap_table_size = 16 M
Current tmp_table_size = 32 M
Of 1740536 temp tables, 0% were created on disk
Effective in-memory tmp_table_size is limited to max_heap_table_size.
Created disk tmp tables ratio seems fine
TABLE SCANS
Current read_buffer_size = 1 M
Current table scan ratio = 742 : 1
read_buffer_size seems to be fine
TABLE LOCKING
Current Lock Wait ratio = 1 : 1185
You may benefit from selective use of InnoDB.
şuan cpu kullanımı ve load lar gayet iyi load 5 üstüne çok az çıktı(genelde 0 ile 2 arasında). son durumu degerlendirirseniz sevinirim. Yardımlarınız için çok tşk ler. |
