Prepare LAMP Environment
LAMP is a model of web service solution stacks, including four oopen source components: Linux, Apache, MySQL, and PHP.
Linux installation is not included since different distributions are almost the same in regard to the installation process. This article provides both ways to deploy the stack for Debian-based and Red Hat-based distributions.
Installation
Install apache
on Debian
# apt-get install apache2
# systemctl enable apache2.service
# systemctl start apache2.service
on CentOS
# yum install httpd
# systemctl enable httpd.service
# systemctl start httpd.service
On CentOS, by default the corresponding port 80 (http) and 443 (https) are closed, you should open them in firewall.
# firewall-cmd --permanent --zone=public --add-service=http
# firewall-cmd --permanent --zone=public --add-service=https
# firewall-cmd --reload
To test Apache, open http://your_ip_address in the browser.
Install mysql
on Debian
# apt-get install mysql-server
# systemctl enable mysql.service
# systemctl start mysql.service
on CentOS
# yum install mariadb-server mariadb
# systemctl enable mariadb.service
# systemctl start mariadb.service
Config Security Settings
# mysql_secure_installation
Install PHP
on Debian
# apt-get install php5
# systemctl restart apache2.service
on CentOS
# yum install php
# systemctl restart httpd.service
To test PHP, first create a .php file.
# vim /var/www/html/info.php
Then paste code as follows as save.
<?php
phpinfo();
?>
Now open http://your_ip_address/info.php in the browser to check php info.
Install MySQL Support in PHP
on Debian
# apt-get install php5-mysql
# systemctl restart apache2.service
on CentOS
# yum install php-mysql
# systemctl restart httpd.service
Create WordPress Database
Login to MySQL
# mysql -u root -p
Create Database
CREATE DATABASE database_name;
Create User
CREATE USER user_name@localhost IDENTIFIED BY 'password';
Grant privileges to new user
GRANT ALL PRIVILEGES ON database_name.* TO user_name@localhost;
Frefresh privileges
FLUSH PRIVILEGES;
Logout
exit
Restart services
on Debian
# systemctl restart apache2.service
# systemctl restart mysql.service
on CentOS
# systemctl restart httpd.service
# systemctl restart mariadb.service
Install WordPress
Download WordPress
# wget http://wordpress.org/latest.zip
Unzip to /var/www/html/
# unzip -q latest.zip -d /var/www/html/
Change ownership
on Debian
# chown -R www-data.www-data /var/www/html/wordpress
on CentOS
# chown -R apache:apache /var/www/html/wordpress
Set permission
# chmod -R 755 /var/www/html/wordpress
On CentOS, also turn off SELinux to get wordpress wizard run properly
Temporarily turn off
# setenforce 0
Permanently turn off
Edit /etc/sysconfig/selinux and update entry as follows
SELINUX=disabled
Open http://localhost/wordpress/ in the browser and finish setup wizard
Revert permission
chown -R root.root /var/www/html/wordpress
