How To Install Shopware on CentOS 7 – Step by Step

Install Shopware on CentOS 7

Shopware is a free and open source e-commerce application written in PHP. It uses MySQL as the database server to store the data. Shopware is very easy to use and require no coding knowledge to work. It is secure and responsive. The application provides the interface for elements to drag and drop, it also supports design grids. It contains story telling, slide shows, and quick views. In this tutorial we will learn how to Install Shopware on CentOS 7.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root accge of Linount, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Shopware on a CentOS 7 server.

Install Shopware on CentOS 7

Step 1. First let’s start by ensuring your system is up-to-date.

yum clean all
yum -y update

Step 2. Install LAMP server.

A CentOS 7 LAMP stack server is required. If you do not have LAMP installed, you can follow our guide here. Also install required PHP modules:

yum -y install php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp php-soap php-tidy curl curl-devel

Step 3. Installing Shopware on CentOS.

Go to the root directory of your system and download the latest stable version of Shopware:

wget https://codeload.github.com/shopware/shopware/zip/5.5
unzip v5.5.zip -d /var/www/html
cd /var/www/html/shopware-5.5 cp -a * ..

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/

Step 4. Configuring MariaDB for Shopware.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next we will need to log in to the MariaDB console and create a database for the Shopware. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Shopware installation:

CREATE DATABASE shopware;
GRANT ALL PRIVILEGES ON shopware.* TO 'shopware'@'localhost' IDENTIFIED BY 'strong_password';
FLUSH PRIVILEGES;
\q

Step 5. Configuring Apache for Shopware.

We will create Apache virtual host for your Shopware website. First create ‘/etc/httpd/conf.d/vhosts.conf’ file with using a text editor of your choice:

nano /etc/httpd/conf.d/vhosts.conf
IncludeOptional vhosts.d/*.conf

Next, create the virtual host:

mkdir /etc/httpd/vhosts.d/
nano /etc/httpd/vhosts.d/yourdomain.com.conf

Add the following lines:

<VirtualHost YOUR_SERVER_IP:80>
ServerAdmin [email protected]
DocumentRoot /var/www/html
ServerName yourdomain.com
ServerAlias www.yourdomain.com
ErrorLog "/var/log/httpd/yourdomain.com-error_log"
CustomLog "/var/log/httpd/yourdomain.com-access_log" combined

<Directory "/var/www/html/">
DirectoryIndex index.html index.php
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>

Save and close the file. Restart the Apache service for the changes to take effects:

systemctl restart httpd.service

Step 6. Accessing Shopware e-commerce.

Shopware will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com or http://server-ip and complete the required the steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.

Congratulation’s! You have successfully installed Shopware. Thanks for using this tutorial for installing Shopware community edition on CentOS 7 systems. For additional help or useful information, we recommend you to check the official Shopware website.

How To Enable Gzip Compression on Nginx CentOS

Enable Gzip Compression on Nginx CentOS

Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or a reverse proxy. So today we’re going to learn how to setup enable Gzip compression on Nginx on CentOS 6 or 7. Compressing your scripts and images is a good idea to optimize your website’s load times.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. In this post, I will talk about an easy way to enable GZIP compression on nginx servers. It’s really not that difficult. Let’s start with Nginx.

Enable Gzip Compression on Nginx

Step 1. Configure nginx.conf (/etc/nginx/nginx.conf)

gzip on;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_proxied any;
gzip_min_length  1100;
gzip_buffers 16 8k;
gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;
gzip_disable "MSIE [1-6].(?!.*SV1)";
gzip_vary on;

Step 2. Now, you simply need to restart your server.

 service nginx restart

If you wish to test if GZIP is enabled, use this command:

 curl -H "Accept-Encoding: gzip" -I https://wpcademy.com

With that file now in place, restart your server and you will now be serving site assets with gzip compression. Google takes site speed into account when ranking and placing your sites in their search engine so do your users a favor and strive for the fastest site possible, especially for mobile users.

Congratulation’s! You have successfully enable Gzip on Nginx. Thanks for using this tutorial for enable gzip compression Nginx on Linux system. For additional help or useful information, we recommend you to check the official Nginx web site.
