WordPress with PHP v. 7.0

By | | Comments 0 Comment

Description

WordPress is a state-of-the-art semantic personal publishing platform with a focus on aesthetics, web standards, and usability.

More simply, WordPress is what you use when you want to work with your blogging software, not fight it.

WWW: http://wordpress.org/.

Requirements

The following applications must be installed, configured and running before installation of WordPress:

  1. Apache HTTP Server
  2. PHP (v. 7.0)
  3. MySQL DB Server
  4. GNUwget

Preparation for Installation

Start PuTTY on a Windows PC, Terminal on a Mac or similar terminal application on a Linux PC.

In this example Terminal on a Mac is used.

Open a remote SSH session to the server with:

Mac:~ user$ ssh user@192.168.1.4 [enter]
N.B.: Replace user@192.168.1.4 with User ID and IP Address on Your server! 
[user@server ~]$

Enable superuser privileges with:

[user@server ~]$ sudo -s [enter]
Password: <-- passwd [enter]
[root@server /usr/home/user]#

N.B.: Enter user password, not the root password!

Warning!

N.B.: Do NOT install WordPress from port if the PHP version installed is > 5.6!

Verify version of PHP installed with:

[root@server /usr/home/user]# php -v <enter>

Prepare MySQL Database

WordPress uses a relational database, such as MySQL, to manage and store site and user information.

Login to the MySQL database with:

[root@server /usr/home/user]# mysql -u root -p <enter>
Enter password: <-- password <enter>
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 422
Server version: 5.7.17-log Source distribution

root@localhost [(none)]>

Create a MySQL wordpress database with:

root@localhost [(none)]> CREATE DATABASE wordpress; &enter>
Query OK, 1 row affected (0,02 sec)

root@localhost [(none)]>

Create a MySQL user account wpadmin that WordPress will use to interact with the wordpress database with:

root@localhost [(none)]> CREATE USER wpadmin@localhost IDENTIFIED BY 'password'; &enter>
Query OK, 0 rows affected (0,44 sec)

root@localhost [(none)]>

 

Grant the WordPress wpadmin user full access to the wordpress database with:

 

root@localhost [(none)]> GRANT ALL PRIVILEGES ON wordpress.* TO wpadmin@localhost; &enter> Query OK, 0 rows affected (0,44 sec) root@localhost [(none)]>

Before this privileges change will go into effect, we must flush the privileges with:

root@localhost [(none)]> FLUSH PRIVILEGES; &enter>
Query OK, 0 rows affected (0,43 sec)

root@localhost [(none)]>

Exit the MySQL prompt with:

root@localhost [(none)]> exit &enter>
Bye
[root@server /usr/home/user]#

Make a copy of the WordPress sample configuration file with:

[root@server /usr/home/user]# cp /usr/local/www/wordpress/wp-config-sample.php /usr/local/www/wordpress/wp-config.php <enter>
