CentOS 7 LAMP Installation from scratch

SSH Remotely (Go ahead and type yes, and then enter your root password.)

• ssh root@123.45.67.890

Change root password

• passwd

Create new root-level superuser

• adduser demo
• passwd demo

Allow this user to run everything that root can

• visudo

Look for the first line below after comment, and add the 2nd line

# User privilege specification
root ALL=(ALL) ALL
demo ALL=(ALL) ALL 

Change SSH port, and disable remote root login

• sudo vi /etc/ssh/sshd_config

Find the following sections and change the information where applicable (add the last line):

Port 12345
PermitRootLogin no
AllowUsers demo

Reload SSH

• systemctl reload sshd.service

Edit "/etc/selinux/config" and change the SELINUX line to "SELINUX=disabled"

New syntax for remote SSH (test this works before disconnecting from root session and rebooting!)

• ssh -p 12345 demo@123.45.67.890

Reboot server to completely turn off SELinux. It will take a while to relabel all files.

Install Apache, PHP, MySQL (MariaDB)

• sudo yum install httpd mariadb-server mariadb php php-mysql

Start services and enable for auto-start

• sudo systemctl start httpd
• sudo systemctl enable httpd.service
• sudo systemctl start mariadb
• sudo systemctl enable mariadb.service

Root for Apache is /var/www/html, so you can test by creating a test file in there with this content

• <?php phpinfo();

Secure MariaDB

• sudo mysql_secure_installation

Add common PHP extensions, then restart Apache

• sudo yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel
• sudo systemctl restart httpd.service

Install FTP server (VSFTPD)

• sudo yum install vsftpd ftp -y
• sudo vi /etc/vsftpd/vsftpd.conf

Find and change this line from YES to NO

• anonymous_enable=NO

Enable auto-start and start 

• sudo systemctl enable vsftpd
• sudo systemctl start vsftpd
