Original Install Apache, PHP and MySQL on CentOS 7 (LAMP)

This tutorial shows how can I install an Apache2 webserver on a CentOS 7.0 server with PHP5 Support (mod_php) and MySQL Support. LAMP is short for Linux, Apache,mysql, PHP.

1 Preliminary Note

The tutorial I use the hostname with the IP address These settings might differ for your, so you has to replace them where appropriate.

I'll add EPEL-7 repo here to install latest phpMyAdmin as follows:


2 Installing MySQL 5

To install MySQL, we do install mariadb like this:

Yum-y Install Mariadb-server mariadb

Then we create the system startup links for MySQL (so, MySQL starts automatically whenever the system boots) and start The MySQL server:

Systemctl Start Mariadb.service
Systemctl Enable Mariadb.service

Set passwords for the MySQL root account:


[Email protected] ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation:line 379:find_mysql_client:command not found

Note:running all PARTS of this SCRIPT are RECOMMENDED for all MariaDB
SERVERS in PRODUCTION use! Please READ each STEP carefully!

In order to log into MariaDB to secure it, we'll need the current
Password for the root user. If you ' ve just installed MariaDB, and
You haven ' t set the root password yet, the password would be blank,
So, should just press ENTER here.

Enter current password to root (enter for none): <--enter
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]
New Password: <--yourmariadbpassword
Re-enter new password: <--yourmariadbpassword
Password Updated successfully!
Reloading privilege tables.
... success!

By default, a MariaDB installation have an anonymous user, allowing anyone
To log into MariaDB without has to has a user account created for
them. This was intended only for testing, and the installation
Go a bit smoother. You should remove them before moving into a
Production environment.

Remove anonymous users? [y/n] <--enter
... success!

Normally, Root should only is allowed to connect from ' localhost '. This
Ensures that someone cannot guess at the root of password from the network.

Disallow Root login remotely? [y/n] <--enter
... success!

By default, MariaDB comes with a database named ' test ' that anyone can
Access. This was also intended only for testing, and should be removed
Before moving into a production environment.

Remove test database and access to it? [y/n] <--enter
-Dropping test database ...
... success!
-Removing privileges on test database ...
... success!

Reloading the privilege tables would ensure that all changes made so far
would take effect immediately.

Reload privilege tables now? [y/n] <--enter
... success!

Cleaning up ...

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

Thanks for using mariadb!
[Email protected] ~]#3 Installing Apache2

CentOS 7.0 ships with Apache 2.4. Apache2 is directly available as a CentOS 7.0 package, therefore we can install it like this:

Yum-y Install httpd

[email protected] ~]# Yum install httpd
Loaded Plugins:fastestmirror, LangPacks
Loading mirror speeds from cached hostfile
Package httpd-2.4.6-17.el7.centos.1.x86_64 already installed and latest version
Nothing to do
[Email protected] ~]#

By default Apache would be installed, If-not then please install it as shown above

Now configure your system to start Apache at boot time ...

Systemctl Start Httpd.service

Systemctl Enable Httpd.service

In the CentOS 7.0 uses firewall-cmd, so I'll customize it to allow external access to port (HTTP) and 443 (HTTPS) .


Now direct your browser to, and you should see the Apache2 placeholder page:

4 Installing PHP5

We can install PHP5 and the Apache PHP5 module as follows:

Yum-y Install PHP

We must restart Apache afterwards:

Systemctl Restart Httpd.service

5 testing php5/getting Details about Your PHP5 installation

The document root of the default Web site is/var/www/html. We are now to create a small PHP file (info.php) in this directory and call it in a browser. The file would display lots of useful details about our PHP installation, such as the installed PHP version.



Now we call that file in a browser (e.g.


As you see, PHP5 is working, and it‘s working through the Apache 2.0 Handler, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don‘t have MySQL support in PHP5 yet.

6 Getting MySQL Support In PHP5

To get MySQL support in PHP, we can install the php-mysql package. It‘s a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:

yum search php

Pick the ones you need and install them like this:

yum -y install php-mysql

In the next step I will install some common PHP modules that are required by CMS Systems like Wordpress, Joomla and Drupal:

yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel

Now restart Apache2:

 systemctl restart httpd.service

Now reload in your browser and scroll down to the modules section again. You should now find lots of new modules like curl etc there.:

7 phpMyAdmin installation

phpMyAdmin is a web interface through which you can manage your MySQL databases.
phpMyAdmin can now be installed as follows:

yum install phpMyAdmin

Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):

vi /etc/httpd/conf.d/phpMyAdmin.conf

Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin

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

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

Next we change the authentication in phpMyAdmin from cookie to http:

vi /etc/phpMyAdmin/

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

Restart Apache:

systemctl restart  httpd.service

Afterwards, you can access phpMyAdmin under
