How to configure LAMP and Wordpress 4.0 on CentOS 7.0

How to configure LAMP and Wordpress 4.0 on CentOS 7.0 

Lets get started, shall we ;)

Check your IP address:
ip addr

Check available Repos:
yum repolist

If you want to save time, downloading at least 'base' packages, configure local 'base'repo.

First install FTP daemon,
yum -y install vsftpd ftp

Loop mount your DVD ISO to copy packages,

mount -o loop,ro /home/yogesh/Downloads/CentOS7.iso /mnt

To check run,
mount  

Now, create folder,
mkdir -p /var/ftp/pub/Centos7

And copy cd contains to your newly created folder,
rsync -av -P /mnt/* /var/ftp/pub/Centos7/.
restorecon -RFvv /var/ftp/pub/Centos7*

Install createrepo package if not installed,
yum -y install createrepo

Execute createrepo,
createrepo -v /var/ftp/pub/Centos7

Start FTP daemon, and open ftp ports in local host.
systemctl start vsftpd
systemctl enable vsftpd
firewall-cmd --permanent --add-service=vsftp
firewall-cmd --permanent --add-service=ftp

Change default repo,
cd /etc/yum.repos.d/

vim CentOS-Base.repo   <Add following line in 'base' section,

enabled=0

Create local repo,

vim local-base.repo

[localbase]

name=CentOS 7 Local Repo

baseurl=ftp://192.168.1.253/pub/Centos7

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

Lets also install EPEL repo for CentOS 7,

yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-1.noarch.rpm
yum clean all ; yum repolist

Now Let is install LAMP packages. System will not download 'Base' packages present in your DVD.  because of local-repo.

First we will install & configure apache,
yum -y install httpd
systemctl start httpd
systemctl enable httpd
firewall-cmd --permanent --add-service=http
systemctl restart firewalld

We will test with web page later,

Now lets install mariadb database,
yum -y install mariadb-server mariadb
systemctl start mariadb 
systemctl enable mariadb 
mysql_secure_installation 

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!

Remove anonymous users? [Y/n] Y

 ... Success!

Disallow root login remotely? [Y/n] 
 ... Success!

Remove test database and access to it? [Y/n] 
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reload privilege tables now? [Y/n] 
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

After mariadb, we will install php.

yum -y install php php-mysql php-gd php-pear
vim /var/www/html/testphp.php

<?php
phpinfo();
?>

You can install GUI Web based php admin console called 'phpmyadmin',

yum -y install phpmyadmin
vim /etc/httpd/conf.d/phpMyAdmin.conf 

Comment and add following lines:

#<Directory /usr/share/phpMyAdmin/>
#   <IfModule mod_authz_core.c>
#     # Apache 2.4
#     <RequireAny>
#       Require ip 127.0.0.1
#       Require ip ::1
#     </RequireAny>
#   </IfModule>
#   <IfModule !mod_authz_core.c>
#     # Apache 2.2
#     Order Deny,Allow
#     Deny from All
#     Allow from 127.0.0.1
#     Allow from ::1
#   </IfModule>
#</Directory>

<Directory /usr/share/phpMyAdmin/>
        Options none
        AllowOverride Limit
        Require all granted
</Directory>

Now open following file:

vim /etc/phpMyAdmin/config.inc.php 

<And  replace 'cookie' with 'http' in following line>

$cfg['Servers'][$i]['auth_type']     = 'http';    // Authentication method (config, http or cookie based)?

Now restart httpd daemon,
systemctl restart httpd

Now your are ready with LAMP server!! :D

Lets see how do we install Wordpress 4.0 (Latest) in the same,

Lets first add hostname in following hosts file,
vim /etc/hosts
192.168.1.25    centos7.localdomain   centos7   <Change as per your hostname and IP>

Download latest package file from wordpress,
wget http://WordPress.org/latest.zip

Unzip and copy over to http root,
unzip latest.zip 
cp -R wordpress/. /var/www/html/

Also make sure you have taken care of Selinux context(If you are using selinux in enforcing mode)

getsebool -a |grep home
setsebool -P httpd_enable_homedirs on
restorecon -RFvvv /var/www/html/*

Now lets setup mariadb for wordpress database,

mysql -u root -p

Enter password: 
MariaDB [(none)]> create database wpdb;
Query OK, 1 row affected (0.01 sec)

MariaDB [(none)]> GRANT ALL ON wpdb.* TO wpuser@localhost IDENTIFIED BY 'centos';
Query OK, 0 rows affected (0.01 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> exit
Bye

Next we have to get a sample file to configure wordpress. This sample file is already shipped in package. Simply copy it and change values in it,

cd /var/www/html/
cp wp-config-sample.php wp-config.php
vim wp-config.php 

define('DB_NAME', 'wpdb');                    <Wordpress database name>

/** MySQL database username */
define('DB_USER', 'wpuser');                  <Wordpress user name>

/** MySQL database password */
define('DB_PASSWORD', 'centos');        <Wordpress user password>

Rest just keep default values.

Now, you are ready with Word press. Open your system URL in browser, in my case its, http://192.168.1.253

Word press will ask you for basic inputs like Site Title, Username, password, email address, etc. After providing those you can open and start using your wordpress! 

:)

Happy Wordpressing!!!
