apache web server üzerinde kullanıcı dizin yapısını aktifleştirmek

Linux üzerinde Apache kullanıyor ve Linux üzerindeki kullanıcılarınıza bir alan açmak istiyorsanız bu işlem için en kolay yöntem userdir eklentisini aktifleştirmek olacaktır. Bunun ne kadar güvenli ve yönetilebilir olduğu tartışılır ancak en kolay yöntem olduğu kesin.

Gerekli modüllerin ve araçların yüklü olduğundan emin olunmalıdır. Aşağıdaki örnek debian tabanlı bir dağıtım da uygulanmıştır. Dağıtımlara göre dizin yapısı vb fark edebilir.

A2enmod ile userdir modülünü aktifleştirelim.

sudo a2enmod userdir

Modül aktifleştirdikten sonra Apache konfigürasyon dosyaları altında userdir modülü ile ilgili konfigürasyon dosyaları oluşturulmuştur. Bu konfigürasyon dosyası içinde gerekli düzenlemeleri yapılması gerekmektedir. 

sudo nano /etc/apache2/mods-enabled/userdir.conf

Temel konfigürasyon dosyası aşağıdaki gibidir. Kullanıcıya açılan dizin ve erişim yetkisi ayarları doğru şekilde ayarlanmalıdır. Yoksa başımıza olmadık işler açabilir. 


        UserDir public_html
        UserDir disabled root
 
        
		AllowOverride All
		Options MultiViews Indexes SymLinksIfOwnerMatch
		
			# Apache < = 2.2:
		        Order allow,deny
		        Allow from all
 
		        # Apache >= 2.4:
		        #Require all granted
		
		
			# Apache < = 2.2:
		        Order deny,allow
		        Deny from all
 
			# Apache >= 2.4:
			#Require all denied

Statik bir alan verecekseniz bu kadar yeterlidir. statik alanmı kaldı diyebilirsiniz. kullanıcıların php kullanmalarını istiyorsanız apachenin php modül konfigürasyon dosyasında gerekli düzenlemeyi yapmanız gerekecektir. 

sudo nano /etc/apache2/mods-available/php5.conf

güvenlik gereği kullanıcı dizinlerinde server-side uygulamalar engellenmiş durumdadır. yapılması gereken “php_admin_value engine Off” satırını pasif ederek sunucu yeni konfigürasyonu ile başlatmaktır.


    
	SetHandler application/x-httpd-php
    
    
	SetHandler application/x-httpd-php-source
    
    # To re-enable php in user directories comment the following lines
    # (from  to .) Do NOT set it to On as it
    # prevents .htaccess files from disabling it.
    
        
    #        php_admin_value engine Off

sunucumuzu yeniden başlattıktan sonra mevcut kullanıcılar için public_html dizinini oluşturmayı unutmayalım..

sudo service apache2 restart
mkdir /home/$USER/public_html

webmin yönetici şifresi resetlemek

bir hata yaptınız ubuntu üzerine webmin yüklediniz ve yönetici şifresi ile sorun yaşıyorsanız aşağıdaki şekilde yönetici şifrenizi resetleyebilirsiniz.

farklı bir dağıtım kullanıyorsanız dizin yapılarında ufak farklılıklar olabilir…

# /usr/share/webmin/changepass.pl /etc/webmin root "yeni şifreniz"

Sonrasında

https://localhost:10000/

Munin

Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort.

Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine “what’s different today” when a performance problem crops up. It makes it easy to see how you’re doing capacity-wise on any resources.

Munin uses the excellent  “‹RRDTool  (written by Tobi Oetiker) and the framework is written in Perl, while plugins may be written in any language. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for data. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).

This site is a wiki as well as a project management tool. We appreciate any contributions to the documentation. While this is the homepage of the Munin project, we will still make all releases through Sourceforge.

Download

All versions are available from  “‹  “‹Sourceforge.

The stable branch is the 2.0.x line, development is happening in 2.1.x.

Munin 2.0 is available in repositories for (at least) the following Linux distributions:  “‹Debian, Ubuntu, Fedora, Red Hat, Red Hat Enterprise Linux, Mandriva, Gentoo and is also available in FreeBSD ports.

5620 SAM Client

Alcatel 5620 SAM clienti kurmanın-çalıştırmanın birden fazla yöntemi var. eğer sunucunuz standart konfigürasyonla kuruldu ise client dosyalarını sam sunucunuz dan edinebilirsiniz.

ssl kullanmıyorsanız :

http://<sam-sunucu-adresi>:8085/client ,

eğer ssl kullanıyorsanız

https://<sam-sunucu-adresi>:8444/client  

adresini tarayınızın adres çubuğuna yazın. karşınıza aşağıdaki şekilde bir sayfa açılacaktır. buradan install or launch linkine tıklayarak SAM clientini  yükleyebilirsiniz.

linux ve windoz işletim sisteminde çalışabilmektedir.

NfSen – Netflow Sensor

NfSen is a graphical web based front end for the  nfdump  netflow tools.

NfSen allows you to:

  • Display your netflow data: Flows, Packets and Bytes using RRD (Round Robin Database).
  • Easily navigate through the netflow data.
  • Process the netflow data within the specified time span.
  • Create history as well as continuous profiles.
  • Set alerts, based on various conditions.
  • Write your own plugins to process netflow data on a regular interval.

Different tasks need different interfaces to your netflow data. NfSen allows you to keep all the convenient advantages of the command line using nfdump directly and gives you also a graphical overview over your netflow data.
NfSen is available at  sourceforge  and distributed under the  BSD license.
