Install WordPress with Nginx on Ubuntu

Harry Naruto — Tue, 12 Jan 2021 07:36:03 +0000

WordPress is one of the most popular and open source content management system (CMS) with a whopping 60% of market share as compared with other CMS like Drupal or Joomla.

WordPress can be used to develop any kind of website, be it for a blog, a small business or for a large enterprise. With its free and premium plugins and themes, a WordPress site can be extended quickly to offer advanced functionalities.

Update your Ubuntu 18.04

Before you start installing NGINX, it is always recommended to upgrade your Ubuntu 18.04 to the latest. The following apt-get commands will do it for you.

# apt-get update 
# apt-get upgrade

The first command will update the list of available packages and their versions and the second one will actually install the newer versions of the packages that you have. Once you are done with upgrading the system, check the release version of your Ubuntu system with the following command.


# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.2 LTS
Release:        18.04
Codename:       bionic

Install WordPress with NGINX on Ubuntu

Step 1: Install NGINX

NGINX is available in the default repositories of Ubuntu and can be installed with a single line command as shown below.

# apt-get install nginx

Once NGINX has been installed, it will run automatically. You can verify that by the following systemctl command.


 # systemctl status nginx
 ● nginx.service - A high-performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: active (running) since Tue 2019-02-12 09:12:08 UTC; 11s ago
     Docs: man:nginx(8)
  Process: 17726 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
  Process: 17714 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
 Main PID: 17729 (nginx)
    Tasks: 2 (limit: 1152)
   CGroup: /system.slice/nginx.service
           ├─17729 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
           └─17732 nginx: worker process

The output of the above command verifies that NGINX is loaded and active with PID of 17729.

Step 2: Install MariaDB

MariaDB is available in the default repository of Ubuntu. It is also possible to install it from the separate MariaDB repository. But we will stick to install it from default repository of Ubuntu. Issue the following commands from the terminal to install it and optionally you can run mysql_secure_installation to make it secure.


# apt-get install mariadb-server 
# systemctl enable mariadb.service
# mysql_secure_installation

The default password for MariaDB root user is blank. To update the password of the root user, get the MySQL prompt and update the password by issuing following command from MySQL shell.


$ mysql -u root -p
MariaDB [(none)]> use mysql;
MariaDB [mysql]> update user SET PASSWORD=PASSWORD("Passw0rd!") WHERE USER='root';

The installation of MariaDB is complete in your Ubuntu 18.04 system. Now proceed with installing PHP in the next step.

Step 3: Install PHP


# apt-get install php7.2 php7.2-cli php7.2-fpm php7.2-mysql php7.2-json php7.2-opcache php7.2-mbstring php7.2-xml php7.2-gd php7.2-curl

Apart from installing php7.2, the above apt-get command also installs few other packages as well like MySQL, XML, Curl and GD packages and makes sure that your WordPress site can interact with the database, support for XMLRPC, and also to crop and resize images automatically.

Further, the php-fpm (Fast process manager) package is needed by NGINX to process PHP pages of your WordPress installation. Remember that FPM service will run automatically once the installation of PHP is over.

Step 4: Create WordPress Database

Once the MariaDB is installed and configured in your server, create a user and a database especially for WordPress installation. To do that, log in to the MariaDB server using mysql -u root -p command and complete the steps as described below.


$ mysql -u root -p
Enter password:

MariaDB [mysql]> CREATE DATABASE wordpress_db;
Query OK, 1 row affected (0.00 sec)

MariaDB [mysql]> GRANT ALL ON wordpress_db.* TO 'wpuser'@'localhost' IDENTIFIED BY 'Passw0rd!' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

MariaDB [mysql]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

MariaDB [mysql]> exit

Step 5: Configure NGINX for WordPress

Let us now proceed with configuring NGINX server blocks to serve your WordPress domain. To start with, create the root folder for your WordPress installation.


# mkdir -p /var/www/html/wordpress/public_html

To create NGINX server block for your WordPress domain, navigate to the /etc/nginx/sites-available folder. This is the default location for NGINX server blocks. Use your favorite editor to create a configuration file for NGINX server block and edit it like below.



# cd /etc/nginx/sites-available
# cat wordpress.conf
server {
            listen 80;
            root /var/www/html/wordpress/public_html;
            index index.php index.html;
            server_name SUBDOMAIN.DOMAIN.TLD;

        access_log /var/log/nginx/SUBDOMAIN.access.log;
            error_log /var/log/nginx/SUBDOMAIN.error.log;

            location / {
                         try_files $uri $uri/ =404;
            }

            location ~ \.php$ {
                         include snippets/fastcgi-php.conf;
                         fastcgi_pass unix:/run/php/php7.2-fpm.sock;
            }

            location ~ /\.ht {
                         deny all;
            }

            location = /favicon.ico {
                         log_not_found off;
                         access_log off;
            }

            location = /robots.txt {
                         allow all;
                         log_not_found off;
                         access_log off;
           }

            location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
                         expires max;
                         log_not_found off;
           }
}

Check the correctness of above configuration file using:


# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

To activate the server block create a symbolic link of the above configuration file inside /etc/nginx/sites-enabled folder.


# cd /etc/nginx/sites-enabled
# ln -s ../sites-available/wordpress.conf .

Reload NGINX to apply the new WordPress domain settings.


# systemctl reload nginx

Step 6: Download and Configure WordPress

In this step, download the archived WordPress file using wget and unzip it to the root of the WordPress installation that we have created in the previous step. To accomplish it run the following commands from the terminal.


# cd /var/www/html/wordpress/public_html
# wget https://wordpress.org/latest.tar.gz
# tar -zxvf latest.tar.gz
# mv wordpress/* .
# rm -rf wordpress

Change the ownership and apply correct permissions to the extracted WordPress files and folders. To do that, use the following command from the terminal.


# cd /var/www/html/wordpress/public_html
# mv wp-config-sample.php wp-config.php
# vi wp-config.php
 ...
 ...
 define('DB_NAME', 'wordpress_db');
 define('DB_USER', 'wpuser');
 define('DB_PASSWORD', 'Passw0rd!');
 ...
 ...

You are now ready to install your WordPress site using your favorite browser.

Step 7: Install WordPress

To complete the installation of WordPress, point your favorite web browser to SUBDOMAIN.DOMAIN.TLD and follow the steps as described below.

The installer will prompt you to choose a language. Choose a language and click ‘Continue’.

Now provide the site information like site title, username, password, email and click on ‘Install WordPress’ button.

You are done with installing WordPress site. Click ‘Log In’ to login to Dashboard and proceed with configuring plugins and themes for your site.

Provide the user name and password that we have entered previously to login for the first time.

Congratulations! Your WordPress website is installed and ready for you to customize according to your requirements.

Conclusion

WordPress is the most popular CMS and we learned how to install it with NGINX on a Ubuntu server. You can now proceed further to create your website with it.

How to add code highlighting and CodePen to your Dev.to posts.

Harry Naruto — Mon, 04 Jan 2021 07:13:00 +0000

This is very simple

const turorialFunction = (name) => {
  console.log(`Hello ${name}`)
}

How to do it

Dev.tos posts are based on Markdown. Within Markdown we can use identation or so called Code Blocks to specify sections of code. The later ones are indicated using

```. Read more about this in this cheatsheet.

Using the three variant we can also specify a language for the code block. A lot of tooling build on top of Markdown utilized this characteristic to implement richer features. But the simplest of them is code highlighting. The above nicely colored code snippet is achieved by starting the code block with``

javascript.

The full example for the above would be:

Windows 8 vs. Windows 7 – Speed And Performance Testing

Harry Naruto — Mon, 04 Jan 2021 05:49:17 +0000

Released on the 26th of October 2012, Windows 8 was Microsoft’s response to the increase in the huge popularity of operating systems in a short period of time.

We have heard much about the new user interface, including that it is disappointing.

At this point we feel that initial reactions with regards to its usability and user experience where the user interface is concerned has been extensively covered.

Therefore, we decided to take on another perspective that can be a source of bad user experience.

I am speaking about speed and performance

Windows 8 vs. Windows 7 – The Experiments

To obtain an unbiased view, together with my colleagues we conducted a number of speed and performance tests so as to compare Windows 8 with Windows 7. For this purpose we have carried out tests such as boot up and shutdown times, file copying, browsing, gaming and similar synthetic benchmarks on two identically machines. To ensure fairness, we also ensured that both versions of Windows were identically configured.

1. Startup Time

Windows 8 Starts Up faster than Windows 7. Windows 8 took 18 seconds while windows 7 took 27 seconds. Calculated diff1erence is 8 seconds.

2. Shutdown Time

A similar improvement is seen when measuring shutdown time. Windows 8 took 8 seconds versus the 12 seconds in windows 7. Calculated difference is 4 seconds.

3. Wake-up From Sleep

Windows 8 shows a marked improvement here as well. However we still thought 10 seconds was too long. We then tested Windows 8 using our SSD and the exact same 10 second window was repeated. While windows 7 took 13 seconds.

4. 3D Graphics Performance

3Dmark 11 is used primarily to measure 3D graphics performance – meaning graphics card drivers play a vital role here. Still, the performance was very similar on both operating systems, though the more mature Windows 7 was slightly faster.

5. Multimedia Performance

Multimedia performance is said to be another of the strengths of Windows 8, and as you can see when testing with PCmark 7, it was 9% faster than its predecessor.

6. Different Browsers with Windows 7 and Windows 8

As you can see, the desktop version of the IE10 browsers on Windows 8 delivered virtually the same performance as IE9 on Windows 7. Chrome works better in Windows 8 incomparison with Firefox runing on indentical Windows 8 computer. Also both Mozilla Firefox and Google Chrome perform faster in Windows 8 than Windows 7. Internet Explorer works very slow in all version of windows.

7.Gaming Performance

By testing these two performance intensive games on both systems we noticed that both operating systems provide similar performance with a very slight edge to Windows 7’s advantage:

Looking at the gaming performance for Battlefield 3, it can be observed that both operating systems provide similar performance with a very slight leading edge for Windows 7.

8. Windows 8 vs. Windows 7 – Conclusion

Microsoft seemed to hit full stride with Windows 7, developing a fast and efficient operating system. Thankfully it seems Windows 8 continues to build on that pattern as we found it to be on par with and occasionally faster than Windows 7. The improvements that have been made to startup and shutdown times are self-evident, and no doubt a major focus on the new OS’ development. This will particularly benefit laptop and tablet users.

At the end we concluded that Windows 8 is faster than Windows 7 in some aspects such as startup time, shut down time, wake up from sleep, multimedia performance, web browsers performance, transferring large file and Microsoft excel performance but it is slower in 3D graphic performance and high resolution gaming performance. Battery life improved enough to be noticeable. Moreover Windows 8 is significantly more secure than Windows 7 and it is basically designed to take advantage of touch screens while Windows 7 is only for desktops. One last word of advice – if you are running Windows 7 on your current PC, then there is no urgency to upgrade the hardware just to run Windows 8…just yet!
