Onderwerp: Mysql problemen

Beste,

Ik heb het volgende probleem sinds een korte tijd draai ik een lanparty site op joomla alleen sinds 2 nachten klapt mysql verbinding weg

Code:

Afgelope nacht herhaalde hij dit weet ik hoevaak er voor:
[Warning] IP address '119.161.148.78' could not be resolved: getnameinfo() returned error (code: -3).

En de hele nacht door:
[ERROR] Error in accept: Too many open files

Nu heb ik op internet gelezen dat To many open files dit het oplosde:
open_files_limit=99000
Nu heb ik dit in /etc/my.cnf gezet ( Ik heb het idee dat hij deze niet als cnf gebruikt kan het mis hebben )

Ik heb mysql ook geupdate naar 5.6.14 vervolgens krijg ik dit in de err log:
2013-10-16 07:28:05 7ffa5490b700 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.
2013-10-16 07:28:05 7ffa5490b700 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.
2013-10-16 07:28:05 7ffa5490b700 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

en

2013-10-16 07:27:48 7ffa5490b700 InnoDB: Error: Fetch of persistent statistics requested for table "nodlan_website"."jos_xmap_items" but the required system tables mysql.innodb_table_stats and mysql.innodb_index_stats are not present or have unexpected structure. Using transient stats instead.

2013-10-16 07:27:48 7ffa5490b700 InnoDB: Error: Table "mysql"."innodb_table_stats" not found.

Van het één krijg ik het ander zou iemand mij kunnen helpen deze website draait voor onze inschrijvingen en moet zo snel mogelijk opgelost worden na een reboot van mysql server werkt het weer...

Met ulimit -a kun je zien wat het actuele limit is.

Na het aanpassen natuurlijk wel ff mysql restarten

root@server1:/home/servers# ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 16382
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
root@server1:/home/servers#


Heb geen idee of dit goed of slecht is ?

moet zeggen in mijn /etc/my.cnf staat bijzonder weinig klopt dit ?

voor het probleem :
[Warning] IP address 'xxx.xxx.xxx.xxx' could not be resolved: Name or service not known

Lees ik dat :
skip_name_resolve

Is dit aan te raden ? + hoe weet ik zeker dan directadmin / mysql de config /etc/my.cnf gebruikt ?

zie dan open files - 1024 Heb nu handmatig met command: ulimit -n 99000 heb op 99000 gekregen

root@server1:/home/servers# ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 16382
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 99000
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200

cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
root@server1:/home/servers#

Maargoed lost dit alle problemen op ? en waarom pakt hij het niet uit my.cnf uit de /etc map...

Websites werken verder wel..

Ook door performance_schema=off in my.cnf te zetten krijg ik de zelfde meldingen... mijn idee is dat my.cfg in etc niet de config is..

MySQL draait niet onder de user "root" waarvoor je de ulimit hebt aangepast.
Bekijk dus ook even de ulimit van de mysql-gebruiker.
Wellicht staat dit nog ergens in je init scripts verstopt?

kan ik dat niet gewoon aanpassen in mysql config want als ik my.cnf aanpas in /etc gebeurd er niks na reboot

skip_name_resolve kan je idd veelal zonder problemen toepassen.

Wat dit doet is het IP-adres van de client terugvoeren naar een hostnaam (reverse DNS).
http://www.vionblog.com/skip-name-re...void-problems/

Probleem is alleen dat dit een DNS look-up vereist (voor elke verbinding!) en als er geen word gevonden het enorm traag word.
Als hij bestaat word hij de lokale cache opgeslagen en is de volgende look-up een stuk sneller, bestaat hij niet dan doet hij iedere keer opnieuw proberen zonder lokale cache.

Eerst moet ik uitzoeken waarom als ik wat in /etc/my.cnf zet het bij een restart niet uitvoerd

Heb bijvoorbeeld:
open files op 99000 gezet

maar bij restart:
open files (-n) 1024

Beste ik heb de limit vast weten te krijgen buiten de config om.... dat vind ik nog steeds een raadsel aangezien op een server waar ik geen DA heb draaien de /etc/my.cnf veel groter is dan 3 regels. Heb gister mysql opnieuw gebuild via DA en tot nu toe met succes meldingen in log tot nu toe :
