These instructions follow my attempts for a generally "locked down" instance for running Word Press without losing sleep.

Version I am working with before updates
Linux ip-172-26-9-250 4.9.51-10.52.amzn1.x86_64 #1 SMP Fri Sep 29 01:16:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

sudo yum -y update
sudo yum -y install libselinux libselinux-utils selinux-policy-minimum selinux-policy-mls selinux-policy-targeted policycoreutils fail2ban httpd mysql mysql-server php php-mysql mod_ssl
sudo sed -i 's/selinux=0/selinux=1\ security=selinux\ enforcing=1/' /etc/grub.conf
sudo echo -e "ServerTokens Prod\nServerSignature Off" >> /etc/httpd/conf/httpd.conf
sudo rm -f /etc/httpd/conf.d/welcome.conf
sudo sed -i 's/expose_php\ =\ On/expose_php\ =\ off/' /etc/php.ini
sudo echo "LoadModule ssl_module /usr/lib64/httpd/modules/mod_ssl.so" >> /etc/httpd/conf/httpd.conf
sudo chkconfig fail2ban on
sudo chkconfig mysqld on
sudo chkconfig httpd on
sudo touch /.autorelabel
sudo reboot
  • After logging back in make sure services are started.
sudo service httpd status
sudo service mysqld status
sudo service fail2ban status
  • Prepare MySQL for Word Press by creating a database.
sudo mysql_secure_installation
mysql -uroot -p
  • Grab Word Press and install in the appropriate location
wget https://wordpress.org/latest.tar.gz
mkdir build
cd build
tar -xf ../latest.tar.gz
mv wordpress /var/www/html/wordpress
  • There are many ways to make this work, I prefer vhosts and sub directories. This will get us up and running with a self signed cert for initial configuration. Afterwards the cert should be updated.
