All of our servers will start with this install. This base server is based on Ubuntu 22.04 LTS Server. I don’t explain much in the howto so if you have a question leave a comment or use Google.
Downloading the ISO
Visit the Ubuntu website and download the ubuntu 22.04 server ISO.
The install screens are straight forward. I’m not going to cover them in much detail. Unless you need to customize a setting, just choose the default settings. Boot the install DVD.
Click ‘Reboot’ when it appears.
Reboot the machine when the install finishes.
The OS will boot. Log in. All the commands need to be run as root so lets start a shell with root privilleges.
> sudo bash
Get everything updated and install a couple of items.
> sudo apt update
> sudo apt dist-upgrade
> sudo apt install software-properties-common
Install and enable ssh.
> sudo apt install ssh
> sudo systemctl enable –now ssh
WARNING: My server isn’t directly connected to the internet. The firewall is disabled to help with installation, configuration and testing easier. Once everything is working, turn on the firewall and configure it. I wil remind you to secure your server at the end of this howto.
now reboot the server.
The Second Boot – Installing Additional Packages
We need quite a few other packages. In this howto I’m installing packages regardless if they were already installed by another dependency. This guards against package changes that could cause a package to not be installed. Once again log in to your server.
Let’s add a 3rd party repo for Apache.
> add-apt-repository ppa:ondrej/apache2
Add a 3rd party repo for PHP.
> sudo add-apt-repository ppa:ondrej/php
Now bring everything up to date.
> sudo apt update && sudo apt upgrade
Install the following packages. Multiple lines to make cut and paste easier.
> sudo apt install make screen snmp composer libcurl4 unzip net-tools
> sudo apt install apache2 libapache2-mod-php mysql-server mysql-client
> sudo apt install libapache2-mod-fcgid php8.2-opcache php-apcu
Install some extra PHP libraries.
> sudo apt install php-gd php-snmp php-mbstring php-mysql
> sudo apt install php-odbc php-imap
> sudo apt install php-xmlrpc php8.2-dba
> sudo apt install php-soap php-zip php-intl php-curl
Configure Apache and PHP
Enable the rewrite module.
> sudo a2enmod rewrite actions fcgid alias proxy_fcgi expires headers
> sudo systemctl enable apache2.service
> sudo systemctl restart apache2.service
We need to set the root password in mysql. so type:
> sudo mysql
Set the root password for mysql.
mysql> ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password by ‘my-secret-password’;
> sudo mysql_secure_installation
Installing and Configuring phpMyAdmin
I prefer to phpMyAdmin to manage my MySQL databases.
Now install phpMyAdmin.
> sudo apt install phpmyadmin
> sudo systemctl restart apache2.service
NOTE: You should think about limiting access to phpMyAdmin. This will help secure your server.
Lets install postfix.
> sudo apt install postfix
When prompted select internet site. Next set the mail server name.
I’m using cockpit as my server admin tool. Do the following to set it up.
> sudo apt install cockpit
> sudo systemctl start cockpit
> sudo systemctl enable cockpit.socket
You can now login to https://yourserver.tld:9090 to administer your server.
NOTE: You should limit access to this service.
Getting root’s and other’s mail
You need to get some local system user’s mail. We’ll use postfix’s virtual file to get the emails to the right place.
Add the following to /etc/postfix/virtual
root email@example.com postmaster firstname.lastname@example.org abuse email@example.com
Now add the configuration option to main.cf
> sudo postconf -e “virtual_alias_maps = hash:/etc/postfix/virtual”
Just a couple commands to wrap everything up.
> sudo postmap /etc/postfix/virtual
> sudo systemctl restart postfix
> sudo systemctl enable postfix
Remove Cloud Init
Our server won’t be using cloud-init. To keep from causing you trouble in the future we will remove it now.
> sudo apt remove cloud-init cloud-initramfs-copymods cloud-initramfs-dyn-netconf
You may want to enable the linux firewall.
Set your timezone in /etc/php.ini
That’s it for the basic server setup. This is an example of a standard linux server setup. Be sure to use cockpit to set which services you want to start at boot time. See the other pages for info on configuring servers for virtual webhosting or virtual email hosting. Remember to configure the firewall on the server.
