This is a living document which reflects the current process, accumulated and tuned over many years, that I use to set up a Ubuntu 20.04LTS LNMP/LAMP stack from scratch. It might not suit everyone, and probably isn't without its flaws, but it's a good foundation for any new server setup, one that I use for dev and production servers alike.
If you would like a quick, no-fuss, local LNMP stack, check out my ubuntu_lnmp_docker_vagrant repository.
- 1. General Setup
- 2.0 GIT
- 3.0 Setup LAMP/LNMP stack
- 3.1 MariaDB (MySQL)
- 3.2 PHP
- 3.4 Nginx (preferred)
- 3.4.1 Create the default site
- 3.4.2 Create basic username/password to lock the default site down with
- 3.4.3 Replace contents of
/etc/nginx/sites-available/default.confwith the following: - 3.4.4 Enable the default site
- 3.4.5 (Optional) Ensure only files with
.phpextension are ever processed byphp-fpm
- 3.5 Apache
- 3.5.1 Fix the error Apache throws about not having a server name
- 3.5.2 Make sure user is part of the www-data group
- 3.5.3 Modify the default site conf
- 3.5.4 Make sure
index.phpis the first default file - 3.5.5 Add the index file to the default site
- 3.5.6 Make sure apache is aware of the changes
- 3.5.7 Now lock down that file with a .htpasswd
- 3.5.8 Enable a few things
- 3.6 Test installation
- 4. Other Useful Things
- 5. Handy Tips

/usr/sbin/groupadd wheel
Next, give SUDOer access to anyone in the wheel group
/usr/sbin/visudo
Add the following lines
## Allows people in group wheel to run all commands
%wheel ALL=(ALL) ALL
It is a bad idea to allow root to log in, so we're going to create a new super user who can.
/usr/sbin/adduser akearney
/usr/sbin/usermod -a -G wheel akearney
On local machine do the following
mkdir ~/.ssh && cd ~/.ssh
ssh-keygen -t rsa -C "[email protected]" -b 4096
cat ~/.ssh/id_rsa.pub
Copy the public key from above and then, back on the new server
mkdir ~akearney/.ssh
nano ~akearney/.ssh/authorized_keys
Paste the public key and save authorized_keys. Then set permissions correctly
chown -R akearney:akearney ~akearney/.ssh
chmod 700 ~akearney/.ssh
chmod 600 ~akearney/.ssh/authorized_keys
Lets change the default port, allow access for a our new user, turn off root login and disallow login with plain password.
nano /etc/ssh/sshd_config
Add/modify the following:
Port 30194 ## <--- change to a port of your choosing
Protocol 2
PermitRootLogin no
PasswordAuthentication no
UseDNS no
AllowUsers akearney
ufw allow 30194/tcp
ufw allow 80/tcp
ufw allow 443/tcp
ufw show added
ufw enable
service ssh restart
Note: DO NOT log out yet. Instead, start a new terminal window and attempt to log in with the new user. This prevents you from being locked out of your server if something was mis-configured.
ssh -p 30194 [email protected]
Add the following to ~akearney/.bashrc then use source ~akearney/.bashrc to apply changes (once logged in as that user). Can add this to root user .bashrc, but recommend using different colour scheme (see below).
PS1='\[\033[0;35m\]\u@\h\[\033[0;33m\] \w\[\033[00m\]: '
##PS1='\[\033[01;36m\]\u@\h\[\033[0;33m\] \w\[\033[00m\]: ' ## Root user colour scheme

Hub is a wrapper for Git which adds github specific commands (change hub-linux-amd64-2.14.2.tgz to suit distro):
wget https://github.com/github/hub/releases/download/v2.14.2/hub-linux-amd64-2.14.2.tgz && \
tar -zxf hub-linux-amd64-2.14.2.tgz && \
mv hub-linux-amd64-2.14.2/bin/hub /usr/bin/hub && \
chmod 755 /usr/bin/hub && \
rm -R hub-linux-amd64-2.*
gh is GitHub on the command line. It brings pull requests, issues, and other GitHub concepts to the terminal next to where you are already working with git and your code.

Open ~akearney/.bashrc and add

Based on article https://www.micah.soy/posts/setting-up-git-identities/
Clear out anything existing
git config --global --unset user.name
git config --global --unset user.email
git config --global --unset user.signingkey
git config --global user.useConfigOnly true
Generate a new key
gpg --full-gen-key
Choose (1) RSA and RSA (default) key type. Choose key size of 4096 bits. Set the key to not expire (0) unless you want to repeat this step periodically. Finally, set your name and email address. Comment can be left blank.
Output the pubilc key. This will output a sec ID in the format of rsa4096/[serial]:
gpg --list-secret-keys --keyid-format LONG [email protected]
Copy the serial number, then run this command to output the public key:
gpg --armor --export <serial>
Copy the public key block and add it to Github settings.
Now we need to create the identities in git’s global config:
git config --global user.github.name "Alannah Kearney"
git config --global user.github.email "[email protected]"
git config --global user.github.signingkey <key>
Create an alias for setting identity per-repo:
git config --global alias.identity '! git config user.name "$(git config user.$1.name)"; git config user.email "$(git config user.$1.email)"; git config user.signingkey "$(git config user.$1.signingkey)"; :'
For each project, specify the git identity to use:
git identity github
This install uses mariadb-server instead of mysql-server (see, https://mariadb.com/kb/en/installing-mariadb-deb-files/).
NOTE: This only works on LTS releases of Ubuntu. Use the MariaDB repo configurator for other releases: https://mariadb.org/download/?t=repo-config
curl -LsS https://r.mariadb.com/downloads/mariadb_repo_setup -o mariadb_repo_setup
bash mariadb_repo_setup --mariadb-server-version=10.7
apt-get update -y
apt-get install -y mariadb-server mariadb-client
systemctl start mariadb.service && systemctl enable mariadb.service
Next, secure the installation. Suggest setting a root user password when prompted.
/usr/bin/mysql_secure_installation
Open nano /etc/mysql/mariadb.conf.d/50-server.cnf and comment out bind-address and skip-external-locking. Then change/add the following under mysqld:
wait_timeout = 600
max_allowed_packet = 64M
Connect to MySQL as root (mysql -u root -p) and run the following:
CREATE USER 'root'@'localhost' IDENTIFIED BY 'root';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;
CREATE USER 'root'@'%' IDENTIFIED BY 'root';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
Restart MySQL with service mysql restart
apt-get remove --purge '^php*' -yq
add-apt-repository ppa:ondrej/php
apt-get update -yq
apt-get install -y php php-pear php-curl php-dev php-gd php-mbstring php-zip php-mysql php-xml php-json php-pcov php-xml php-intl
Install the PHP7.4 libraries
apt-get install -y php7.4 php-pear php7.4-curl php7.4-dev php7.4-gd php7.4-mbstring php7.4-zip php7.4-mysql php7.4-xml php7.4-json php7.4-pcov
This will most likely install both PHP 7.4 and 8.x (with 8 being the default). To switch to 7.4, update the symlink in /usr/bin like so:
cd /usr/bin
rm php.default
ln -s php7.4 php.default
Verify the correct version with php --version. Output should look like this:
PHP 7.4.22 (cli) (built: Jul 30 2021 13:08:17) ( NTS )

Install some libraries. Note, this assumes PHP8.1. Change php-fpm to php7.4-fpm for 7.4.x

Remove any existing stuff (just in case):
apt-get remove --purge "^certbot*"
For Ubuntu 20.04LTS Focal use snapd:
apt-get install snapd -yq
snap install --classic certbot
ln -s /snap/bin/certbot /usr/bin/certbot
For Ubuntu versions lower than 20.04LTS use the folllowing (see, https://certbot.eff.org/lets-encrypt/ubuntufocal-nginx):
add-apt-repository ppa:certbot/certbot
apt-get update
apt-get install software-properties-common python-certbot-apache python-certbot-nginx
Check that certbox will automatically try to renew certificates.
systemctl status certbot.timer
The command to renew certbot is installed in one of the following locations:
/etc/crontab/
/etc/cron.*/*
systemctl list-timers
If necessary, add the following to the crontab (crontab -e) to trigger a renew action on a regular basis
14 0 * * * certbot renew --quiet --no-self-upgrade
14 11 * * * certbot renew --quiet --no-self-upgrade
Run and enable certificates for selected hosts
