Mam wykupiony serwer vps, dopiero co przeżuciem bloga na wordpressie na niego, a codziennie odnotowuje jakąś zwiechę parametry vps procesor 3Ghz ram gwarantowany 1024 MB mam odpalony tylko lighttpd php5 mysql serwer raz dziennie potrafi się powiesić brak pinga, brak usług, trup, w panelu administracyjnego gdzie mogę go zrestartować jest informacje że działa. brak jakichkolwiek informacji które mogłyby mnie naprowadzić na problem z logach co to może być ? dodam że my.conf nie ruszałem php.ini chyba ważna jest memory_limit=256M Czytam po google że może mysql zdziera cały ram i dlatego się wiesza, ale nie było by nić w logu ? Ruch na blogu jest raczej nieduży max userów 20 online jak skonfigurować optymalnie my.conf i php.ini dla parametrów mojego serwera proszę o pomoc -- MYSQL PERFORMANCE TUNING PRIMER -- - By: Matthew Montgomery - MySQL Version 5.1.66-0+squeeze1 i486 Uptime = 0 days 0 hrs 34 min 31 sec Avg. qps = 42 Total Questions = 88364 Threads Connected = 1 Warning: Server has not been running for at least 48hrs.

Current long_query_time = 10.000000 sec. You have 0 out of 88385 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 = 0 Current threads_cached = 0 Current threads_per_sec = 1 Historic threads_per_sec = 0 Your thread_cache_size is fine MAX CONNECTIONS Current max_connections = 151 Current threads_connected = 1 Historic max_used_connections = 4 The number of used connections is 2% 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 = 4 M Current InnoDB data space = 7 M Current InnoDB buffer pool free = 0 % Current innodb_buffer_pool_size = 8 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 : 28 M Configured Max Per-thread Buffers : 405 M Configured Max Global Buffers : 17 M Configured Max Memory Limit : 423 M Physical Memory : 1.50 G Max memory limit seem to be within acceptable norms KEY BUFFER Current MyISAM index space = 11 M Current key_buffer_size = 7 M Key cache miss rate is 1 : 2495 Key buffer free ratio = 88 % Your key_buffer_size seems to be fine QUERY CACHE Query cache is supported but not enabled Perhaps you should set the query_cache_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 = 132.00 K You have had 47 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_open_cache = 64 tables Current table_definition_cache = 256 tables You have a total of 118 tables You have 64 open tables. Current table_cache hit rate is 4% , while 100% of your table cache is in use You should probably increase your table_cache TEMP TABLES Current max_heap_table_size = 16 M Current tmp_table_size = 16 M Of 13759 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 = 128 K Current table scan ratio = 281 : 1 read_buffer_size seems to be fine TABLE LOCKING Current Lock Wait ratio = 1 : 22179 Your table locking seems to be fine
