Tag,

Undzwar beobachte ich schon seit längerem, das mir der Apache sowie der MySQL Server mir den Ram wegfrisst.

Ich hab hier bestimmt 20 - 25 mySQL Prozesse und auch in etwa soviele apache2 Prozesse.

Hier mal die Ausgabe von top

Code:

top - 13:37:56 up 6 days,  3:21,  1 user,  load average: 9.70, 8.11, 8.54

Tasks: 215 total,   1 running, 213 sleeping,   0 stopped,   1 zombie

Cpu(s):  0.0%us,  0.0%sy,  0.0%ni, 74.5%id, 25.5%wa,  0.0%hi,  0.0%si,  0.0%st

Mem:  16406500k total,  9455744k used,  6950756k free,   217140k buffers

Swap:  3997680k total,        0k used,  3997680k free,  8582008k cached

Wie man sieht ist die load sehr hoch.

Und hier mal die config files

apache2.conf

Code:

#

# Based upon the NCSA server configuration files originally by Rob McCool.

#

# This is the main Apache server configuration file.  It contains the

# configuration directives that give the server its instructions.

# See http://httpd.apache.org/docs/2.2/ for detailed information about

# the directives.

#

# Do NOT simply read the instructions in here without understanding

# what they do.  They're here only as hints or reminders.  If you are unsure

# consult the online docs. You have been warned.  

#

# The configuration directives are grouped into three basic sections:

#  1. Directives that control the operation of the Apache server process as a

#     whole (the 'global environment').

#  2. Directives that define the parameters of the 'main' or 'default' server,

#     which responds to requests that aren't handled by a virtual host.

#     These directives also provide default values for the settings

#     of all virtual hosts.

#  3. Settings for virtual hosts, which allow Web requests to be sent to

#     different IP addresses or hostnames and have them handled by the

#     same Apache server process.

#

# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# server will use that explicit path.  If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so "foo.log"

# with ServerRoot set to "/etc/apache2" will be interpreted by the

# server as "/etc/apache2/foo.log".

#

### Section 1: Global Environment

#

# The directives in this section affect the overall operation of Apache,

# such as the number of concurrent requests it can handle or where it

# can find its configuration files.

#

#

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# NOTE!  If you intend to place this on an NFS (or otherwise network)

# mounted filesystem then please read the LockFile documentation (available

# at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>);

# you will save yourself a lot of trouble.

#

# Do NOT add a slash at the end of the directory path.

#

#ServerRoot "/etc/apache2"

#

# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.

#

LockFile ${APACHE_LOCK_DIR}/accept.lock

#

# PidFile: The file in which the server should record its process

# identification number when it starts.

# This needs to be set in /etc/apache2/envvars

#

PidFile ${APACHE_PID_FILE}

#

# Timeout: The number of seconds before receives and sends time out.

#

Timeout 10

#

# KeepAlive: Whether or not to allow persistent connections (more than

# one request per connection). Set to "Off" to deactivate.

#

KeepAlive On

#

# MaxKeepAliveRequests: The maximum number of requests to allow

# during a persistent connection. Set to 0 to allow an unlimited amount.

# We recommend you leave this number high, for maximum performance.

#

MaxKeepAliveRequests 100

#

# KeepAliveTimeout: Number of seconds to wait for the next request from the

# same client on the same connection.

#

KeepAliveTimeout 3

Durch die ganzen Prozesse was mySQL und Apache2 angeht, laden natürlich die Seiten deutlich länger, oder das laden der Seite wird abgebrochen.

mysqltuner hab ich auch schon benutzt und auch die Vars angepasst.

Ich hoffe ihr könnt mir bei dem Problem helfen.

Ich würde am besten mal die komplett Ausgabe von top posten.

Hab noch nen paar Screens von htop beigefügt.

600 MB RAM werden genutzt... das ist nicht wirklich viel für eine gut besuchte Seite, die ich dir einfach mal unterstelle.
Auch sind 25 Threads nicht wirklich viel. Da hatte ich schon deutlich mehr Wink

Würde mir mehr Sorgen über die CPU Auslastung machen, die sieht in meinen Augen min. auf dem einen Screen nicht gut aus.

Ich hab gerade mal eine Seite auf dem Host geladen, hier kannst du mal auf dem Screen sehen, wie die MySQL Prozesse die CPU in die Höhe treiben.

Das sieht echt nicht normal aus... welches CMS nutzt du? Und hast du eine Möglichkeit (z.B. Google Analytics) um die momentane Besucherzahl herauszufinden?

Der jenige nutzt etwas selbst geschriebenes.
Aber es läuft überwiegend webSPELL auf dem Host.
Google Analytics ist zwar vorhanden bei der Seite, aber dadrauf hab ich keinen Zugriff

Hast du Skype? Könnte mal drüberschauen per TeamViewer oder so Wink

Gesund sieht das auf jeden Fall nicht aus, kann dir per Skype dann auch mal nen Screen von meinem Server senden ^^ da läuft sogar noch nen kleiner MC Server und er hat weniger CPU Load!

Schonmal in die php.ini geschaut Wink

?
Die php.ini findest du in /etc/php5/apache2/php.ini
Kannst ja mal schauen auf was das memory_limit gesetzt ist, wenn du meinst das zu viel RAM verwendet wird, kannst du das memory_limit runterschrauben, aber nicht unbedingt empfehlenswert.
Standardmäßig sollten 128M konfiguriert sein.

Hast du einen v oder Dedicated-Server ?

Falls vServer würde ich mich mal erkundigen wie viel CPU Leistung du von deinem Hoster bekommst, insofern keine Vollvirtualisierung kann es sein, das andere vServer auf deinen übergreifen und dir deine Leistung nehmen Wink

Du hast 16GB Arbeitsspeicher, da sind ca. 600MB doch nichts.

Ich bin bereits dabei, ihm zu helfen Wink

wir haben das Problem schon. Es sind Floods aus China. Sind grad dabei, alles zu blocken und dagegen abzusichern.
