adduser saul sudo # adds saul to the sudo group
sudo usermod -a -G www-data saul # add saul to the www-data group
Setting up Authentication Keys
ssh-keygen -b 4096 # create the keyfile - do this on the client (watch you don't overwrite your existing one if you have done this before!)
ssh-copy-id saul@LINODE_IP # uploads the public key to linode
Configure SSH
sudo nano /etc/ssh/sshd_config
# Modify these lines to look like this:
PermitRootLogin no # this stops root from logging in
PasswordAuthentication no # this stops anyone from logging in without authentication keys
sudo service ssh restart # reboots ssh and applies changes

KeepAlive Off # keepalive allows fast connections to those who are already connected but may hold up other clients
# Append these lines to the end of the file:
<IfModule mpm_prefork_module>
StartServers 4
MinSpareServers 20
MaxSpareServers 40
MaxClients 200
MaxRequestsPerChild 4500
</IfModule>
sudo service apache2 restart # restart apache to apply changes
Configure Virtual Hosts For Apache
sudo a2dissite *default # Disable the default Apache virtual host
cd /var/www/html
sudo mkdir example.com
sudo mkdir example.com/public_html
sudo mkdir example.com/log
sudo mkdir example.com/backups
sudo nano /etc/apache2/sites-available/example.com.conf
# domain: example.com

ErrorLog /var/www/html/example.com/log/error.log
CustomLog /var/www/html/example.com/log/access.log combined
</VirtualHost>
sudo a2ensite example.com.conf # adds a link in the correct location to the configuration file
sudo service apache2 restart
# Rince and repeat for any other websites to host.
# Optional:
#sudo nano /etc/hosts # This is to test the virtual hosts and is done on the local computer
# Append a line like this
IP.ADRRESS.OF.THE.LINODE example.com
Install And COnfigure MySQL
sudo apt-get install mysql-server
sudo mysql_secure_installation # set a unique password, remove anonymous user accounts, disable remote root login, and remove the test database
sudo nano /etc/mysql/my.cnf # for optimising mysql
max_allowed_packet = 1M
