• A registered domain name with working HTTPS (TLS/SSL). HTTP/2 only works alongside HTTPS because most browsers, including Firefox and Chrome, don’t support HTTP/2 in cleartext (non-TLS) mode.

• Also you need at least Apache version 2.4.24

• If you run PHP in Apache via mod_php, you need to switch to FPM. That is not a bad thing. FPM is newer and faster.

Now lets do the configuratoin for HTTP/2

Switching Apache’s PHP Module from MPM Prefork to Event
Run the following commands:

sudo apt-get install php7.2-fpm
sudo a2enmod proxy_fcgi
sudo a2enconf php7.2-fpm
sudo a2dismod php7.2
sudo a2dismod mpm_prefork
sudo a2enmod mpm_event
sudo service apache2 restart

Installing and Enabling HTTP/2 in Apache

Enable the module mod_http2:

sudo a2enmod http2
sudo service apache2 restart

Enable the HTTP/2 protocol by adding the following to /etc/apache2/apache2.conf:

Protocols h2 http/1.1

Verify that HTTP/2 is Working

Cloudflare put together a comprehensive list of ways you can check a website for HTTP/2 support. The easiest to use are probably Chrome Dev Tools (network view, add the Protocol column) or the online test from KeyCDN.

 sudo mv /etc/vsftpd.conf /etc/vsftpd.conf_orig 
 sudo nano /etc/vsftpd.conf

Now paste below code in vsftpd.conf file:

listen_port=4021

listen=NO

listen_ipv6=YES

anonymous_enable=NO

local_enable=YES

write_enable=YES

local_umask=022

dirmessage_enable=YES

use_localtime=YES

xferlog_enable=YES

connect_from_port_20=YES 

connect_from_port_20=NO

chroot_local_user=YES

secure_chroot_dir=/var/run/vsftpd/empty

pam_service_name=vsftpd

rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

ssl_enable=NO

pasv_enable=Yes

pasv_min_port=10000

pasv_max_port=10100

allow_writeable_chroot=YES

Restart VSFTPD service and it will start to listen on port 4021

service vsftpd restart

Now create sftp group:

groupadd sftp

Modify /etc/ssh/sshd_config file to disable users that are part of sftp group to login by a ssh client.

nano /etc/ssh/sshd_config

Add the following line in the end of the file

Match group sftp
ChrootDirectory /home
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftp

Restart the SSH server

service ssh restart

Now let’s create a user and give it a password

useradd myftpuser

passwd  myftpuser

Change a home folder of your “myftpuser” user:

usermod -d /var/www/myftpuser/www myftpuser

Root must be owner of the path /var/www/myftpuser/:

chown root:root /var/www/myftpuser/

Add user to sftp and www-data group:

usermod  myftpuser -G sftp, www-data

Check groups of your newly created user:

groups  myftpuser  

Groups www-data and sftp should be listed.

Make www-data owner of the web folder there all of your files will be stored:

chown www-data:www-data /var/www/myftpuser/www/ 

Last but not least try to ssh into your myftpuser account. You should not be able to login.

The next step is try login to your FTP but don’t forget to use port: 4021 that we specified above.

Also do not forget to allow port 4021 in your firewall. I use ufw firewall so the following command will allow port 4021:

 ufw allow 4021

On an Apache server, it’s possible to password protect a directory using .htaccess and .htpasswd files. However, .htaccess files are not supported on Nginx.

You can still password protect your directories, but you need to use a basic_auth.conf file instead.

Creating the file

1. Log into your server via SSH.
2. Navigate to your user’s directory.
3. Make sure you have a /home/username/nginx/example.com directory.This doesn’t exist by default; you must create it by running the following:

   sudo mkdir -p nginx/example.com

4. In this /home/username/nginx/example.com directory, add a file named ‘basic_auth.conf‘ with the following:

   location / {
           auth_basic "Restricted";
           auth_basic_user_file /home/username/nginx/example.com/.htpasswd;
   }

   * The auth_basic parameter is just the title of the prompt the user sees when visiting this directory.
   * The auth_basic_user_file parameter specifies where the password file is. Note how its path is set to the /nginx directory.

   In this example, the ‘location’ directive password protects the entire domain since it’s pointing to ‘/’.
   If you want a subdirectory to be password protected, change the ‘location’ directive as follows:

   location /subdirectory/

5. Run the following to create the .htpasswd file:

   sudo htpasswd -c /home/username/nginx/example.com/.htpasswd LOGIN

   * LOGIN is the username you want to be used to authenticate in the login prompt.

6. After typing that command, enter a password and confirm it when prompted:

   New password: 
   
   Re-type new password:

   Adding password for user LOGIN

7. Reload the nginx config file.

   sudo service nginx reload

8. In your browser, load the directory your /home/username/nginx/example.com/basic_auth.conf points to. *In the example above, this would be your domain’s root directory since the ‘location’ directive points to /.
9. Enter a user/password when prompted to log in.
   * In this example, your username is LOGIN and the password is the one you created above.

Above we can see the timezone is UTC (Coordinated Universal Time).

UTC is the default time zone. To avoid timezone confusion and the complexities of adjusting clocks for daylight saving time in accordance with regional custom, it is often recommended that all servers use UTC.

If your site or application requires a different system timezone, start by listing the available options:

timedatectl list-timezones
Africa/Abidjan
Africa/Accra
Africa/Addis_Ababa

Now its time to set your time zone. Mine timezone is Europe/Stockholm

sudo timedatectl set-timezone Europe/Stockholm

Now check if the timezone has been set correctly.

We can see the timezone has changed to CET, which correct for Stockholm.

This is how to do it.

sudo apt-get -y purge ubuntu-desktop
sudo apt-get -y purge unity gnome-shell lightdm
sudo apt-get -y remove ubuntu-desktop
sudo apt purge ubuntu-desktop -y && sudo apt autoremove -y && sudo apt autoclean
sudo apt-get -y clean
sudo apt-get -y autoremove
sudo apt-get -f install

However if you need to install it again just run the following command:

Code:

<div id=”search”>
<div class=”button-search”></div>
<?php if ($filter_name) { ?>
<input type=”text” name=”filter_name” value=”<?php echo $filter_name; ?>” />
<?php } else { ?>
<input type=”text” name=”filter_name” value=”<?php echo $text_search; ?>” onclick=”this.value = ”;” onkeydown=”this.style.color = ‘#000000’;” />
<?php } ?>
</div>

Now I will paste this code in my content_top.tpl file located in the same directory as header.tpl

Open up header.php that is located in /catalog/controller/common/ directory
and copy these code lines:

Code:

$this->language->load(‘common/header’);
$this->data[‘text_search’] = $this->language->get(‘text_search’);
if (isset($this->request->get[‘filter_name’])) {
$this->data[‘filter_name’] = $this->request->get[‘filter_name’];
} else {
$this->data[‘filter_name’] = ”;
}

Paste these lines into the file /catalog/controller/common/content_top.php under public function index(). Just paste it below the line 10 or 11.

Copy now language variable for the input search text to the right language file.

Copy variable $_[‘text_search’] = ‘Search’; from /language/-yourlangugage-/common/header.php to /language/-yourlangugage-/yourlanguage.php

The last thing we need to make is to copy js function that will post our search. Your search field is for sure not placed in the #header at this time so we need to copy function from /catalog/view/javascript/common.js and rename it.

Copy and paste this function into the same js file and don’t forget to rename #header according to your div’s/container’s ID (#example) or class (.example).

Code:

$(‘#header input[name=’filter_name’]’).keydown(function(e) {
if (e.keyCode == 13) {
url = $(‘base’).attr(‘href’) + ‘index.php?route=product/search’;
var filter_name = $(‘input[name=’filter_name’]’).attr(‘value’)

if (filter_name) {
url += ‘&filter;_name=’ + encodeURIComponent(filter_name);
}

location = url;
}
});

My div container looks like this <div id=”example”>….search field code…</div> so my javascript function for submitting the search form will look like this:

Code:

$(‘#example input[name=’filter_name’]’).keydown(function(e) {
if (e.keyCode == 13) {
url = $(‘base’).attr(‘href’) + ‘index.php?route=product/search’;
var filter_name = $(‘input[name=’filter_name’]’).attr(‘value’)

if (filter_name) {
url += ‘&filter;_name=’ + encodeURIComponent(filter_name);
}

location = url;
}
});
