Install LAMP On CentOS

Description:

Follow these steps to install the LAMP stack on CentOS 7. LAMP= Linux, Apache, MySQL, and Php.

To Resolve:

1. First MySQL, Open a terminal => type:

   # This will change in the future, just get the latest release for CentOS
   sudo wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
   
   # Extract the rpm
   sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
   
   # Install Mysql
   sudo yum install mysql-server
   
   # Start the service
   systemctl start mysqld
   
   # Initiate the secure install script. Keep in mind it is asking about a database user called root which you don't know the password, so just hit enter. Not your current root password. It will then prompt you to set it.
   sudo mysql_secure_installation
   
   # Now enter whatever lines (one at a time) to create a database and user, in this example, WordPress:
   mysql -u root -p <enterPassword>
   CREATE DATABASE wordpress;
   CREATE USER "wordpressuser"@"localhost" IDENTIFIED BY "password";
   GRANT ALL PRIVILEGES ON wordpress.* TO "wordpressuser"@"localhost" IDENTIFIED BY "password";
   FLUSH PRIVILEGES;
   exit
   
   # Lastly, set Mysql to run on startup
   sudo systemctl enable mysqld
   

   • Useful Commands:

   # Shows databases
   SHOW DATABASES;
   
   # Shows users
   select host, user, password from mysql.user;
   

2. Next, Apache. Open a terminal and type:

   sudo yum install httpd mod_ssl
   
   sudo systemctl start httpd
   
   # Uncomment out and replace "servername" with your server's hostname.
   sudo vi /etc/httpd/conf/httpd.conf
   
   # Restart the service
   sudo systemctl restart httpd
   
   # Add firewall rules
   firewall-cmd –zone=public –add-port=80/tcp –permanent
   
   # Set it to run on startup, you should also be able to use "sudo systemctl enable httpd.service".
   sudo systemctl enable httpd
   

3. Lastly, install PHP:

   # Install php
   sudo yum install php php-mysql php-devel php-gd php-pecl-memcache php-pspell php-snmp php-xmlrpc php-xml
   
   # Restart apache
   sudo systemctl restart httpd
