How to install wordpress in linux

WordPress is a powerful, free and open-source, highly pluggable and customizable CMS that is being used by millions around the world to run blogs and fully functional websites.

It is easy to install and learn, especially for persons who do not have prior website design and development knowledge.

Step 1: Install Apache Web Server
   To install apache server follow the instructions below
   $ sudo apt-get install apache2 apache2-utils 
 
   Now we need to check whether it is installed or not
    Go to the browser and type localhost if it is shown like this then no problem your apache is installed successfully
 

NOTE: The default Apache root directory is /var/www/html all your files are stored in the directory.

STEP 2: Install MYSQL Database Server:

   Now we need to install the MYSQL Database Server by running this command

  $ sudo apt-get install mysql-client mysql-server

During the package installation, you will be prompted to set the root user password for mysql .

To open the mysql ,type 

      $ mysql -u root -p in terminal

STEP 3 : Install PHP and Modules

    

       we can install PHP by type the command in terminal

       $ sudo apt-get install php7.0 php7.0-mysql libapache2-mod-php7.0 php7.0-cli php7.0-cgi php7.0-gd  

 OR

   sudo systemctl restart apache2 

for 19.0 and above

To check the PHP is  installed properly , we need to create a info.php file inside /var/www/html. $ sudo vi /var/www/html/info.php

And paste the code below into the file, save it and exit.

   <?php 

    phpinfo();

    ?>  

Then open the browser and type localhost/info.php .If you find a screen like this then no problem
all set is ok.

STEP 4: Install WordPress CMS;

   Download the latest version of wordpress by typing the command below:

$ wget -c http://wordpress.org/latest.tar.gz
$ tar -xzvf latest.tar.gz

Then move the WordPress files from the extracted folder to the Apache default root directory, /var/www/html/:

$ sudo rsync -av wordpress/* /var/www/html/

Next, set the correct permissions on the website directory, that is give ownership of the WordPress files to the web server as follows:

$ sudo chown -R www-data:www-data /var/www/html/
$ sudo chmod -R 755 /var/www/html/

STEP 5: Create WordPress Database

 Type the command 

   $ mysql -u root -p

At the mysql shell, type the following commands, pressing Enter after each line of a mysql command. Remember to use your own, valid values for database_name, databaseuser, and also use a strong and secure password as databaseuser_password

mysql> CREATE DATABASE wp_myblog;
mysql> GRANT ALL PRIVILEGES ON wp_myblog.* TO 'your_username_here'@'localhost' IDENTIFIED BY 'your_chosen_password_here';
mysql> FLUSH PRIVILEGES;
mysql> EXIT;

Go the /var/www/html/ directory and rename existing wp-config-sample.php to wp-config.php

Open the file wp-config.php and change the dbname,dbuser,db_password,and etc

Note: Do not change all the things.

Afterwards restart the server by this command

$ sudo systemctl restart apache2.service 
$ sudo systemctl restart mysql.service 

Open your web browser, then enter your server address: http://server-address to get the welcome page and enter the asked detail.
