Son bir yıl içinde bozulan ikinci disk

Son bir yıl içinde ikici 1 TB seagate diskimde bozuldu.
Önemli bilgilerimin bir kısmını kayıp etsemde, büyük çoğunluğunu testdisk ile kurtarabildim.
 Testdisk programını yazanlara teşekkür ederim.
Bozuk disklerden veri kurtarma ihtiyacı duyarsanız, testdiski kullanabilirsiniz.

Seagate disklerine 3 yıldan fazla kullanmamak, 3 yılını dolduran diskleri bozulmasa bile yenisi ile değiştirmek gerekiyor!!!!

Diskin verdiği hatalar ve smartctl programının söyledikleri aşağıda;

Windows ve jumbo paket

Bu gün Windows 2012 sunucusunda disk kullanımında performansı artırmak için jumbo paket boyutunu 9014 yapıyor fakat 1500 byte üzerinde paketleri iletmiyor.
Sorun windows ile birlikte gelen standart intel ethernet kartı sürücüsünden kaynaklanıyor. Ethernet kartı Intel® Ethernet Controller X540-AT2  Intel'in sayfasından sürücüyü indirip yükledikten sonra ethernet kartı 10Gbit ve 9000 byte paketleri iletmeye başladı. Buda gösteriyorki, daima ürün üreticisinin sürücülerini kullanmak gerekiyor. Tembellik edip, sürücüyü ürün üreticisinin sürücüsü ile güncellemezsek, sistemden yeterince verim alamayız...

Denenmesi gereken yerli bir ürün!

Her hangi bir güvenlik yazılımına ihtiyacı olan arkadaşlarımız; epati firmasının ürününü denemesini gereken bir ürün olarak düşünüyorum.

nginx kullanıcıları için faydalı bir döküman

Birden fazla bölgede sunucuları olan nginx kullanıcıları için;


https://www.digitalocean.com/community/tutorials/how-to-use-nginx-as-a-global-traffic-director-on-debian-or-ubuntu


To complete this guide, you will need a user with sudo privileges.
 You also need to know how to create servers in different regions.
Assumptions

This article makes a few assumptions for ease of readability.
Your domain is www.example.com
Your primary server is in the US
You want to install a GTD for Europe and Asia
Your server IPs are as follows: US: 1.1.1.1 EU: 1.1.1.2 AS: 1.1.1.3
Subdomains and DNS configuration

Choosing subdomains is all up to you. For this tutorial, let's use eu.example.com for Europe and as.example.com for Asia.

For each of those subdomains, add an A record in your DNS configuration with the IP of the server for that region:
eu.example.com - 1.1.1.2
as.example.com - 1.1.1.3

It should look something like this:


Install Nginx and GeoIP

To have Nginx with a GeoIP module, you have two options: 1) use a precompiled package (only -full and -extra have GeoIP module) or 2) compile your nginx with the --with-http_geoip_module configuration parameter – In this case, you also need geoip-dev libraries.

Let's use the already available repository packages.
sudo apt-get update
sudo apt-get install nginx-full geoip-database

Now both Nginx and GeoIP binaries are available. But there is one more thing: GeoIP's city database includes region information. You need to download and install it manually.
wget -N http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoLiteCity.dat.gz
mv GeoLiteCity.dat /usr/share/GeoIP/
Configure Nginx and your virtual host

Here we are going to tell Nginx where the GeoIP database files are. And in our virtual host, we are going to configure how Nginx will respond to requests based on their geoip information.

Open nginx.conf (default /etc/nginx/nginx.conf) with your preferred editor. Add the line geoip_city /usr/share/GeoIP/GeoLiteCity.dat;. Your nginx.conf will look like this:
http {
  geoip_city /usr/share/GeoIP/GeoLiteCity.dat;
  ...
}

Save it.

Now let's edit your virtual host (default /etc/nginx/sites-available/default). Inside we need to create a map and add the subdomains to the server_name directive.

The map in Nginx allows us to set a variable $closest_server based on the value of $geoip_city_continent_code. You can read more about the Map module on Nginx's documentation.
map $geoip_city_continent_code $closest_server {
  default www.example.com;
  EU      eu.example.com;
  AS      as.example.com;
}

Next we add the location-based subdomains to the $server_name directive:
server {
  server_name example.com
              www.example.com
              eu.example.com
              as.example.com;
  ...
}

The last part of the process is to make a condition in your virtual host that redirects visitors to the closest server. Add the following condition to your configuration:
server {
  ...

  if ($closest_server != $host) {
    rewrite ^ $scheme://$closest_server$request_uri break;
  }

  ...
}

After you're done with all the changes your virtual host file would look like this:
map $geoip_city_continent_code $closest_server {
  default www.example.com;
  EU      eu.example.com;
  AS      as.example.com;
}

server {
  server_name example.com
              www.example.com
              eu.example.com
              as.example.com;

  if ($closest_server != $host) {
    rewrite ^ $scheme://$closest_server$request_uri break;
  }

  ...
}

Repeat this step for each server you want to configure. That way all of your servers will act as a traffic directors.
Run a few tests

After completing all of these steps, the final one is to test what you have done. When working with Nginx, always test new configurations before applying.

Nginx provides an option to test its configuration files, without affecting currently running Nginx. You can do that by running one of these commands:

nginx -t, service nginx configtest or /etc/init.d/nginx configtest

If everything is good - Reload your Nginx configuration:

nginx -s reload, service nginx reload or /etc/init.d/nginx reload

To see your traffic director in action. Open a browser and visit www.example.com:

If you visit the site using a proxy in Europe, you should be redirected to eu.example.com:

If you visit the site using a proxy in Asia, you should be redirected to as.example.com:

And from now on your global visitors will be immediately redirected to a server closest to them, improving their experience on your website.

birazda opencart

 Opencart için
ExcelPort - Product / Category / Customers Excel Export / Import
http://www.opencart.com/index.php?route=extension/extension/info&extension_id=10197 eklentisini kullanıyorsanız, karşılaşacağınız en büyük sorun php ram kullanım sorunudur.

Bu sorunu aşmak için php.ini dosyasını ayarlamanız yetmiyor. Çünkü php dosyaları içinde tanım yapılmış durumda.
 Düzeltmek için;
                       admin/controller/module/excelport.php
                       admin/controller/tool/export.php

dosyaları içinde memory_limit (        ini_set('memory_limit', '1024M'); ) değişkenini bularak artırmanız. Ben 7000M yaptım.


İlave olarak script çalışma süresini artırmak gerekiyor. Malum script yarım saatten fazla sürede çalışmasını tamamlıyor.

Artırmak için de
                           admin/controller/module/excelport.php
                           admin/controller/tool/export.php
dosyaları içinde
max_execution_time değişkenini bularak ayarlamanız gerekli.

Ben süreyi bir saat olarak ayarladım.

admin/controller/tool/export.php:ini_set('max_execution_time', 3600);

timeout

iyi tasarlanmamış php scripti kullanıyorsak ve timeout sorunu ile karşılaşıyorsak;

scriptimizin başına;

ini_set('max_execution_time', 3600);
ini_set('memory_limit', '6000M');

ilave etmemiz çözüm fakat tam çözüm değil. Çünkü firefox'unda timeout değerini artırmamız gerekiyor.

Aksi durumda scriptimiz web sunucusu üzerinde çalışmaya devam eder, fakat firefox timeout düşer.
