Installation of Apache MySQL and PHP in centos 7

Linux

LAMP stands for Linux, Apache, MySQL and PHP. Its is used for hosting websites written with PHP programming language and using MySQL as backend database server. This will help you to install LAMP stack (Apache 2.4, MySQL 8 and PHP 7.1/7.2/7.3) on CentOS 7

Step 1 – Prerequisites

Adding EPEL repo here to install required packages

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*
# yum -y install epel-release

Step 2 – Install Apache

# yum -y install httpd*

Now start httpd service and enable on boot using below commands.

# systemctl start httpd
# systemctl enable httpd

Step 3 – Install MySQL Server

First we need to add mysql community repository to install mysql.For reference visit repo.mysql.com repository to download latest rpms for any other OS.

# rpm -Uvh  https://repo.mysql.com/mysql80-community-release-el7-1.noarch.rpm

Default mysql repository is enabled and ready for installation.

# yum -y install mysql-server

Install  1 Package (+3 Dependent packages)

once it is installed start and enable mysql service with below commands.

# systemctl start mysqld
# systemctl enable mysqld

Apply security on newly installed MySQL server. This will also prompt you to change the temporary password with a new password.

# grep "A temporary password" /var/log/mysqld.log

# mysql_secure_installation

Change the password for root?   - y
Remove anonymous users?   - y
Disallow root login remotely?    - y
Remove test database and access to it?    - y
Reload privilege tables now?   - y

Mysql has been installed.Next we will install php

Step 4 – Install PHP

The PHP version that comes with CentOS as default is quite old (PHP 5.4).Here we will install latest versions using Remi repository.

Add the Remi CentOS repository as below

# rpm -Uvh http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Install yum-utils as we need the yum-config-manager utility.

# yum -y install yum-utils

For php 7.0

# yum-config-manager --enable remi-php70

For php 7.1

# yum-config-manager --enable remi-php71

For php 7.2

# yum-config-manager --enable remi-php72

For php 7.3

# yum-config-manager --enable remi-php73

select one of the version from above and enable remi repo and install php

# yum -y install php php-devel php-gd php-bcmath php-pdo php-mcrypt php-tidy php-mysql php-xml php-soap php-imap php-pgsql php-mbstring

After installing php along with modules you must restart Apache service

# systemctl restart httpd

Step 5 - Testing PHP

The document root of the default website is /var/www/html. We will create a small PHP file (info.php) in that directory and call it in a browser to test the PHP installation.
