LEMP stack (minus the PHP)

Today we’re going to be talking about building a LEMP stack! Many of you may be familiar with LAMP stacks (Linux Apache MySQL PHP). A LEMP stack is Linux, Nginx, MySQL and PHP (however we’re substituting PHP with Python because.. well…. Php.

I’m currently using a KVM server with a Linux Mint jumpbox. I SSH in with the -X switch to bring up the virt-manager GUI. However, you do not need this. This config can work whether you’re running a Linux VM on Hyper-V, ESXi, KVM, OpenStack, AWS, Azure, etc. You can even do this on a local Linux install.

The first thing we’re going to do is pick a Linux distro. As I love me some RedHat, we’re going to go with the free developer license for RedHat. You can sign up for this on RedHat’s subscription site and have up to 16 VM’s licensed and subscribed for free. If you do not want to do this, feel free to download CentOS.

The first thing we will install is the epel-release repo. This is due to yum missing some packages. The two ways to do this are;

sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum update

Next, we are going to install Nginx

yum install nginx -y (the -y is so you don’t get prompted to choose yes)

To start Nginx and confirm it’s up, run;

systemctl start nginx
systemctl status nginx
curl privateipaddress

Once that is up, you should be able to go into a web browser, type in your private IP address over port 80, and see the Nginx splashpage.

example;
http://192.168.1.60:80

Up next, we will install MySQL. This varies based on what application you will be working with and the requirements. In our case, we will go with the latest and greatest.

wget https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
rpm -ivh mysql80-community-release-el7-1.noarch.rpm
yum update
yum install mysql-server

To change the MySQL default password, take a look at /var/log/mysqld.log. You will get the default MySQL password. To log into mysql, type:

mysql –u root –p temppassword

After you confirmed you can log in, run through;
mysql_secure_installation

After that, confirm you can log into MySQL with your new password.

Finally, we will install the P in LEMP. It’s typically PHP, but today we will use Python!

We will install development tools so we can compile our install of Python3.6. Do the exact following;
sudo yum groupinstall -y "Development Tools"

Cd /tmp (this is where your installs should go before running. /tmp removes automatically every 10 days so you don’t have files sitting around that you don’t need).

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz

tar –xvf Python-3.6.3.tar.xz
ls Python-3.6.3
./configure
make install

After this, type “which python3”.

Congrats! You have officially compiled your first (maybe your first) application AND built your first LEMP stack. Now go and tell everyone of your god-like status.
