Hoşuma gidenler

Bir eticaret framework ü olarak ücretsiz ve büyük sistemler için kullanılabilir çok kapsamlı bir fw, ama woocommerce gibi lightweight değildir iyi bir CPU ve Ram ister.

Mükemmel bir mimarisi vardır, php,composer ve diğer frameworkleri katmanlamıştır,  veritabanı mimarisi EAV olduğu için alışana kadar anlamakta zorluk çekebilirsiniz. 

E-ticarete yeni girdiyseniz ve büyük bir sistem düşünüyorsanız hemen başlangıç yapabilirsiniz, Uyarı büyük ölçekte ürününüz yoksa woocommerce ile başlamanızı tavsiye ederim daha az maliyetli olacaktır.

Programcıya verdikleri sınıf ve api lerde eticaret ile ilgili aklınıza gelebilecek herşeyi düşünmüşler mutlaka çoğu olayın Observer patterni var ve işinizi çok kolaylaştırıyor kendinizde Observer pattern eklebiliyorsunuz. 

Çok fazla harici eklentisi var uygun fiyatlara internette bulabilirsiniz.

Temaları çok uygun fiyata ve kaliteli olarak themeforest da satılıyor.  

Hoşuma Gitmeyenler ve artık nefret etme sebeblerim 

Yukarıda dediğim gibi mimari mükemmel ama çok katmanlı mimari olduğu için hata çıkması durumunda çok fazla gezinmek zorunda kalıyorsunuz. Neden bu kadar fazla fw yi depency yaptıkları konusundaki düşüncem ise kullanmak istediği bir fonksiyonu yada sınıfı mesela symfony paketinde bulmuş hemen eklemişler kendilerine uygun şekilde yazmaktansa nasıl olsa symfony yazıyor demişler.

Kendi modülünüzü yapmak için ve yüzde %80 herşey de magento ya bağımlı kalmak çok sıkıcı ama eklenti geliştirme için verdiği api ve arayüz başarılıdır.

Frontend tarafı bence tam baş belası inspector araçı gibi bişey vardı onunla hangi html nerede onları gösteriyordu orası çok hayat kurtaran özellik ama frontend bence çok zaman alan çok uğraştıran bir olay kodlama bilgisi olamayan frontend ci bile çok fazla kodlama öğrenmek zorunda kalabilir, klasör yapılarını zaten bilmek zorunda kalacaksınız.

Öyle durumlar oluyor ki php ve html kodları içiçe olduğundan  javascipt de iş yapmakla bitmiyor php de onu kodlamak return etmek gerekiyor backend ve frontend olarak çalışanlar için tam sıkıntılı bir olay, aslında magento için fullstack yazılımcı olmak şart oluyor.

magento 2 artık jquery ve knockout kullanıyor ama magento 1 prototype.js bağımlıydı mesela  ürün variant ekleme sırasında prototype.js ye  depency eklemek 1 haftadan fazla zamanımı almıştı.

Backend tarafı Magento 1 php nin en zor fw si olan zendi kullanıyordu magento 2 de daha fazla depency geldi yani daha fazla bilgi istiyor.

Kendi içindeki cache sistemini açmazsanız çok çok yavaş o kadar çok katman olduğu çin input/output sayısı çok fazla php nin yorumlaması çok uzun zaman alıyor. Birde javascript bağımlılıklarını da unutmamak gerekiyor.

Debug yaparken insanı kanser ediyor bu süreler “android de debug yap kazancın harcadığın zamana değer :) “

Magento ile çalışan şirketler olaya profesyonel olarak bakmıyor herşeyi hazır sistem,  arayuzü düzenle biter diyor ama çoğu zaman modul/eklenti geliştiriyorsun bu modülleri robot yazmıyor ki arkadaş sen zamanını, deneyimini  satarak para kazanıyorsun. Magento ile uğraşmak yerine java-c# ile falan uğraşın çok çok daha tatmin eder ve iyi maaşlar alırsınız.

Ve son olarak herkes öyle mi bilmiyorum ama böyle bir sistemle bu kadar karmaşa ile uğraşıp gerçekten hakkettiğiniz maaşı veren hiç bir şirket yok, zaten uğraşan şirkette az yazılımcıda az,  siz siz olun sakın profesyonel olarak magento yazılımcısı olmayın.

Magento günün sonunda sizi tatmin etmiyor, yazılımcılık yapmıyorsunuz aslında herşeyin hazırını yapıyorsunuz.

Ben 3 yıldır go ve c# yazıyorum iyi ki artık php ve frameworkleri ile ilgilenmiyorum diyorum ama php de tek sevdiğim şey wordpress kaldı,  WP de bazen eşe dosta eklenti yazarım, WP biraz eğlenceli geliyor çünkü herşey daha terli toplu duruyor.

When you transfer the data the insert records on these specific records are automatically generated and tend to start at 1 and not 0.

This script worked for me:

SET FOREIGN_KEY_CHECKS=0;
UPDATE `store` SET store_id = 0 WHERE code='admin';
UPDATE `store_group` SET group_id = 0 WHERE name='Default';
UPDATE `store_website` SET website_id = 0 WHERE code='admin';
UPDATE `customer_group` SET customer_group_id = 0 WHERE customer_group_code='NOT LOGGED IN';
SET FOREIGN_KEY_CHECKS=1;

Hope it helps.

– Generate SSL Letsencrypt

We will secure our Magento installation using SSL from Letsencrypt. Install the Letsencrypt using the apt command below.

sudo apt install letsencrypt -y

After the installation is complete, stop the nginx service.

systemctl stop nginx

Now generate the SSL certificates for the domain name using certbot command as below.

certbot certonly --standalone -d magento.hakase-labs.pw

Type your email address, accept the Letsencrypt TOS, then type ‘N’ for email sharing.

When it’s complete, you will get the result as below.

The Letsencrypt SSL certificate files have been generated to the ’/etc/letsencrypt/live’ directory.

FOR SSL  Configure Nginx Virtual Host file

upstream fastcgi_backend {
        server  unix:/run/php/php7.1-fpm.sock;
}

server {
    listen 80;
    listen [::]:80;
    server_name www.magento-dev.com;
    return 301 https://$server_name$request_uri;
}

server {

        listen 443 ssl;
        server_name magento-dev.com;

        ssl on;
        ssl_certificate /etc/letsencrypt/live/magento.hakase-labs.pw/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/magento.hakase-labs.pw/privkey.pem;

        set $MAGE_ROOT /var/www/magento2;
        set $MAGE_MODE developer;
        include /var/www/magento2/nginx.conf.sample;
}

location ~ (index|get|static|report|404|503).php$ {

to :

location ~ (index|get|static|report|404|503|phpinfo).php$ {

and place phpinfo.php to the pub subfolder because pub declared as document root at line 21:

root $MAGE_ROOT/pub;

I use my own Nginx config for Magento 2 and it permits phpinfo.php in the root folder.

Create or edit an administrator

Use this command to create a new administrator or to edit an existing administrator. If you’re editing an administrator, only the first name, last name, and password can be edited.

Command usage:

php bin/magento admin:user:create [--<parameter_name>=<value>, ...]

The password must be at least 7 characters in length and must include at least one alphabetic and at least one numeric character.

We recommend a longer, more complex password. Enclose the entire password string in single quotes. For example, --admin-password=''A0b9%t_3g'.

https://devdocs.magento.com/guides/v2.0/install-gde/install/cli/install-cli-subcommands-admin.html#create-or-edit-an-administrator

1. You can reinstall your project

2. By mistake you forget your admin URL; You can see/change admin URL from

   app/etc/env.php at line no 5.

   return array (
   'backend' =>
   array (
   'frontName' => 'admin_q76xvk',
   ),

3. Clean cache/reindexing and delete var/cache , var/page_cache folder.

4. Make change in .htaccess (Just copy this file pub/.htaccess to magento root folder)

• Ubuntu 18.04
• 2GB or more RAM memory
• Root privileges

What we will do

1. Install PHP Composer
2. Download Magento 2
3. Install Magento Components
4. Generate SSL Letsencrypt
5. Configure Nginx Virtual Host for Magento
6. Magento Post-Installation

Step 1 – Install Nginx on Ubuntu 18.04 LTS

In this tutorial, we will be using the Nginx web server for our Magento installation.

Log in to the server, update the repository, and upgrade all packages.

sudo apt update<br>sudo apt upgrade

Now install the Nginx web server using the apt command below.

sudo apt install nginx -y

After the installation is complete, start the Nginx service and enable it to launch every time at system boot.

systemctl start nginx<br>systemctl enable nginx

Nginx web server has been installed, check it using netstat command and make sure the HTTP port 80 is on the ‘LISTEN’ state. Another way is by using curl command as below.

netstat -plntu<br>curl -I localhost

Step 2 – Install and Configure PHP-FPM 7.1

After the Nginx web server installation, we will install PHP 7.1 on the server as Magento does not support PHP 7.2 yet. We will install PHP-FPM with all extensions needed by Magento 2.

List of PHP extensions needed for Magento 2 installation:

• bc-math
• ctype
• curl
• dom
• gd, ImageMagick 6.3.7 (or later) or both
• intl
• mbstring
• mcrypt
• hash
• openssl
• PDO/MySQL
• SimpleXML
• soap
• spl
• libxml
• xsl
• zip
• json
• iconv

For this guide, we will install PHP-FPM packages from the PPA repository. We will be using the ‘ondrej/php’ repository.

Install the ‘software-properties-common’ package and add the ‘ondrej/php’ repository using commands below.

sudo apt install software-properties-common -y<br>
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ondrej/php -y
sudo apt-get update
sudo apt-get install -y php7.1

Now install PHP-FPM 7.1 with all extensions needed.

sudo apt install php7.1-fpm php7.1-mcrypt php7.1-curl php7.1-cli php7.1-mysql php7.1-gd php7.1-xsl php7.1-json php7.1-intl php-pear php7.1-dev php7.1-common php7.1-mbstring php7.1-zip php7.1-soap php7.1-bcmath -y

After the installation is complete, check the PHP version and installed extensions using PHP commands.

php -v<br>php -me

Next, we will configure the php.ini file for the PHP-FPM and PHP-CLI.

Edit the php.ini files using nano

vim /etc/php/7.1/fpm/php.ini<br>vim /etc/php/7.1/cli/php.ini

Change the value of those lines as below.

memory_limit = 512M
max_execution_time = 180
zlib.output_compression = On

Save and exit.

or 

sed -i "s/memory_limit = .*/memory_limit = 512M/" /etc/php/7.1/fpm/php.ini
sed -i "s/upload_max_filesize = .*/upload_max_filesize = 128M/" /etc/php/7.1/fpm/php.ini
sed -i "s/zlib.output_compression = .*/zlib.output_compression = on/" /etc/php/7.1/fpm/php.ini
sed -i "s/max_execution_time = .*/max_execution_time = 18000/" /etc/php/7.1/fpm/php.ini

sed -i "s/memory_limit = .*/memory_limit = 512M/" /etc/php/7.1/cli/php.ini
sed -i "s/upload_max_filesize = .*/upload_max_filesize = 128M/" /etc/php/7.1/cli/php.ini
sed -i "s/zlib.output_compression = .*/zlib.output_compression = on/" /etc/php/7.1/cli/php.ini
sed -i "s/max_execution_time = .*/max_execution_time = 18000/" /etc/php/7.1/cli/php.ini

Now restart the PHP-fpm service and enable it to launch every time at system boot.

systemctl restart php7.1-fpm<br>systemctl enable php7.1-fpm

The PHP-FPM 7.1 installation and configuration has been completed, check the service using netstat command.

netstat -pl | grep php

And you will get the PHP-fpm socks file as below.

WARNING

https://stackoverflow.com/questions/16002268/prevent-nginx-504-gateway-timeout-using-php-set-time-limit

or Step 2.1 – Install and Configure PHP-FPM 7.0

sudo apt install software-properties-common -y<br>sudo add-apt-repository ppa:ondrej/php -y

Now install PHP-FPM 7.0 with all extensions needed.

sudo apt install php7.0-fpm php7.0-mcrypt php7.0-curl php7.0-cli php7.0-mysql php7.0-gd php7.0-xsl php7.0-json php7.0-intl php-pear php7.0-dev php7.0-common php7.0-mbstring php7.0-zip php7.0-soap php7.0-bcmath -y<br>

After the installation is complete, check the PHP version and installed extensions using PHP commands.

php -v<br>php -me

Next, we will configure the php.ini file for the PHP-FPM and PHP-CLI.

Edit the php.ini files using nano

vim /etc/php/7.0/fpm/php.ini<br>vim /etc/php/7.0/cli/php.ini

Change the value of those lines as below.

memory_limit = 512M
max_execution_time = 180
zlib.output_compression = On

Save and exit.

or

sed -i "s/memory_limit = .*/memory_limit = 512M/" /etc/php/7.0/fpm/php.ini
sed -i "s/upload_max_filesize = .*/upload_max_filesize = 128M/" /etc/php/7.0/fpm/php.ini
sed -i "s/zlib.output_compression = .*/zlib.output_compression = on/" /etc/php/7.0/fpm/php.ini
sed -i "s/max_execution_time = .*/max_execution_time = 18000/" /etc/php/7.0/fpm/php.ini

sed -i "s/memory_limit = .*/memory_limit = 512M/" /etc/php/7.0/cli/php.ini
sed -i "s/upload_max_filesize = .*/upload_max_filesize = 128M/" /etc/php/7.0/cli/php.ini
sed -i "s/zlib.output_compression = .*/zlib.output_compression = on/" /etc/php/7.0/cli/php.ini
sed -i "s/max_execution_time = .*/max_execution_time = 18000/" /etc/php/7.0/cli/php.ini

Now restart the PHP-fpm service and enable it to launch every time at system boot.

systemctl restart php7.0-fpm<br>systemctl enable php7.0-fpm

The PHP-FPM 7.0 installation and configuration has been completed, check the service using netstat command.

netstat -pl | grep php

And you will get the PHP-fpm socks file as below.

Step 3 – Install and Configure MySQL Server

The Magento software requires MySQL 5.6.x, and the Magento 2.1.2 or later require the MySQL 5.7.x. In this tutorial, we will install latest MySQL server 5.8 on the Ubuntu 18.04 system.

Install MySQL 5.8 using the apt command below.

sudo apt install mysql-server mysql-client -y

After the installation is complete, start the MySQL service and enable it to launch every time at system boot.

systemctl start mysql<br>systemctl enable mysql

Now we will configure the MySQL root password using ‘mysql_secure_installation’ command.

mysql_secure_installation

In this MySQL 5.8 version, there is a security improvement for the MySQL password policy. You need to choose the password policy – 0 for the LOW policy, 1 for the MEDIUM policy, and 2 for a STRONG password policy.

For this guide, we will be using the ‘MEDIUM’ password policy, and it’s recommended to use the ‘STRONG’ password policy on the

Choose number ‘1’ and press Enter, then type your new MySQL ‘root’ password.

 Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y
 Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y
 Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y
 Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y

The MySQL root password has been set up.

You can increase the value for packet which is larger than Magento default by opening /etc/mysql/mysql.cnf in a text editor and navigate to max_allowed_packet.  

Then, save to mysql.cnf and restart MySQL by entering service mysql restart.

Run the following command at a mysql> prompt to verify your set value:

SHOW VARIABLES LIKE 'max_allowed_packet';

Next, we will create a new database for our Magento installation. We will create a new database named  ‘magentodb’ with user ‘magentouser’ and the password is ‘Magento0463@#’.

Login to the MySQL shell using the root user.

mysql -u root -p

Now run MySQL queries below to create the database and user.

create database magentodb;<br>create user magentouser@localhost identified by 'Magento0463@#';<br>grant all privileges on magentodb.* to magentouser@localhost identified by 'Magento0463@#';<br>flush privileges;

The MySQL server installation and configuration for the Magento installation has been completed.

Step 4 – Install and Configure Magento 2

In this step, we will install Magento 2.2.4 latest version from Github repository. We will install the PHP composer for installing the Magento components, download Magento from Github repository, configure Nginx virtual host for Magento, and install Magento using the web-based post installation.

– Install PHP Composer

Install PHP Composer on ubuntu 18.04 using the apt command below.

sudo apt install composer -y

After the installation is complete, check the composer version installed on the system.

composer -V

The latest version PHP Composer has been installed.

– Download Magento 2

Go to the ’/var/www’ directory and download the Magento archive source code from Github using wget command.

cd /var/www/<br>wget <a href="https://github.com/magento/magento2/archive/2.2.6.tar.gz">https://github.com/magento/magento2/archive/2.2.6.tar.gz</a>

Now extract the Magento archive file and rename the directory to ‘magento2’.

tar -xf 2.2.6.tar.gz;<br>mv magento2-2.2.6/ magento2/;

The Magento source code has been downloaded, and the ’/var/www/magento2’ directory will be the web root for the Magento site.

– Install Magento Components

Install Magento components using the PHP composer. Go to the ‘magento2’ directory and install all the PHP components needed by Magento using the ‘composer’ command.

cd /var/www/magento2;<br>composer install -v;

If you plan to install Sample data – refer to this link for details. As for now Magento 2 is still under development, the best variant is to read the latest documentation at Magento docs.

File permissions

‘Admin’ user is the owner of all magento files on our server, and Apache web server runs on behalf of ‘www-data’ user. Magento 2 documentation describes the access permission settings for files and directories on the principle that the web server runs on behalf of the user which is the owner of all Magento files. Our opinion is: it’s not the best decision, as it can lead to security issues (as the web server has permissions to write and run the code) as well as issues with setting access permissions for third party developers (as you’re not logging in as www-data user). We normally use the following access permissions:

cd /var/www/magento2
find var vendor pub/static pub/media app/etc -type f -exec chmod g+w {} ;
find var vendor pub/static pub/media app/etc -type d -exec chmod g+ws {} ;
chmod u+x bin/magento

If you’re going to install Magento from the web interface, then add write permissions for app/etc/ and vendor/:

chmod -R g+w /var/www/magento2/{app/etc,vendor}

 Configure nginx

1. Run the line to create a new virtual host for your Magento site:

vim /etc/nginx/sites-available/magento

1. Make the following configuration:

upstream fastcgi_backend {
     server  unix:/run/php/php7.1-fpm.sock;
 }

 server {

    listen 80;
    #listen [::]:80;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;
    set $MAGE_ROOT /var/www/magento2;
    #client_max_body_size 200M;
    #set $MAGE_MODE developer;
    include /var/www/magento2/nginx.conf.sample;
 }

1. Match your domain name with the base URL you chose when installing Magento.
2. Save and exit the editor.
3. Activate host by creating a symlink:

ln -s /etc/nginx/sites-available/magento /etc/nginx/sites-enabled

1. Delete the default configuration:
   
   
2. sudo rm -f /etc/nginx/sites-enabled/default
3. Verify if the syntax is correct:
   
   

nginx -t

Run the command to restart nginx:

systemctl restart nginx

Verify the installation

Now try your site’s URL on a web browser to verify the site yourself.
