Step 4. Configuring MariaDB for Pimcore.

Step 5. Configuring Apache web server for Pimcore.

Step 6. Configuring the ports in firewall for Pimcore.

Step 7. Accessing Pimcore.

Prerequisites

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 account, 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 PimCore CMS on a CentOS 7 server.
Install PimCore 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-xml php-xmlrpc php-mbstring php-mcrypt php-mssql php-snmp curl curl-devel

Step 3. Installing PimCore.

Download the latest stable release of Pimcore to your server:

wget https://www.pimcore.org/download/pimcore-data.zip

Unpack the Pimcore archive to the document root directory on your server:

mkdir /var/www/html/pimcore/
unzip pimcore-data.zip -d /var/www/html/pimcore/

We will need to change some folders permissions:

chown apache:apache -R /var/www/html/pimcore

Step 4. Configuring MariaDB for Pimcore.

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 Pimcore. 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 Pimcore installation:

MariaDB [(none)]> CREATE DATABASE pimcore DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON pimcore.* TO 'pimcore'@'localhost' IDENTIFIED BY 'strong_password';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Step 5. Configuring Apache web server for Pimcore.

We will create Apache virtual host for your Pimcore 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:

ServerAdmin [email protected]
DocumentRoot "/var/www/html/pimcore/"
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/pimcore/">
DirectoryIndex index.html index.php
Options FollowSymLinks
AllowOverride All
Require all granted

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

systemctl restart httpd.service
systemctl enable httpd.service

Step 6. Configuring the ports in firewall for Pimcore.

Modify firewall rules in order to allow access for visitors:

firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --reload

Step 7. Accessing Pimcore.

Pimcore 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.

Change the Default Search URL Slug in WordPress – Easy Guide

Change the Default Search URL Slug

WordPress search URLs are not user friendly. In this article, we will show you how to easily change the default search url slug in WordPress and make it more SEO and user friendly.

Why Change Default Search URL Slug in WordPress

WordPress uses SEO friendly URL structure for all pages on your website. Typical SEO friendly WordPress URLs look like this:

http://example.com/some-page/
http://example.com/2018/03/some-article/
http://example.com/category/some-category/

As you can see, these URLs are quite easy to understand for users as well as search engines.

However, WordPress still uses non-friendly URL for search results page. A typical search URL in WordPress looks like this:

http://example.com/?s=search-term

This URL structure doesn’t match the rest of your website URLs. While some WordPress search plugins improve the search results, most don’t do anything about the search URL itself.

What if you can make your search URL look like:

http://example.com/search/your-search-term/

Let’s take a look at how to make the WordPress search page URL slug more SEO friendly.

Changing Search Page URL Slug in WordPress

For this tutorial you will need to edit your WordPress theme files. If you haven’t done this before, then please take a look at our guide on how to copy and paste code in WordPress.

Method 1. Change WordPress Search URL Slug via Functions File

This method is easier and recommended for most users.

First, you need to copy and paste the following code in your theme’s functions.php file or a site-specific plugin:

function wpb_change_search_url() {
    if ( is_search() && ! empty( $_GET['s'] ) ) {
        wp_redirect( home_url( "/search/" ) . urlencode( get_query_var( 's' ) ) );
        exit();
    }   
}
add_action( 'template_redirect', 'wpb_change_search_url' );

Don’t forget to save your changes.

You can now go to your website and try using the search feature. You will notice that the search URL looks like this:

http://example.com/search/your-search-query/

Method 2. Change Search URL Slug via htaccess File

The .htaccess file is often used to set up redirects and other website configuration tasks. You can also use it to change the default search URL slug in WordPress.

Your .htaccess file is located in your website’s root folder, and you will need to use FTP or File Manager app in cPanel to edit it. Refer to this guide, if you can’t find the .htaccess file.

In your .htaccess file, you need to paste the following code at the bottom:

# Change WordPress search URL
RewriteCond %{QUERY_STRING} \\?s=([^&]+) [NC]
RewriteRule ^$ /search/%1/? [NC,R,L]

Don’t forget to save your changes and upload the .htaccess file back to the server.

You can now go to your website and use the search feature. You will notice the search URL will now look like this:

http://example.com/search/your-search-query/

We hope this tutorial helped you change the default search URL slug in WordPress.
