Install Mkcert for SSL on Localhost

Mkcert is a simple tool for generating locally-trusted development SSL/TLS certificates. It requires minimal configuration.

 Prerequisites (Ubuntu / Debian) 

 Make sure you have: 

 

 

 libnss3-tools installed 

 

 

 Homebrew (Linuxbrew) if you want to install via brew 

 

 

 To install on Debian (Ubuntu) use the following commands: 

 sudo apt install libnss3-tools 

 Install  LinuxBrew

 – get the  installer 

 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" 

 Enable it 

 test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)

test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

test -r ~/.bash_profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile

echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile 

 Install mkcert 

 brew install mkcert;

mkcert -install; 

 If at this point you are getting a  mkcert command not found  , or  Warning: /home/linuxbrew/.linuxbrew/bin is not in your PATH.  you many need to fix  the global PATH var to include the mkcert bin folder. Edit your ~/$HOME/.profile file and add the following : 

 if [ -d "/home/linuxbrew/.linuxbrew/bin" ] ; then

 PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"

fi 

 Save the .profile file and from the terminal run  source ~/.profile 

 An alternative way to install Mkcert is the following (not fully tested by me):  

 sudo apt-get update

sudo apt install wget libnss3-tools

set MCVER="v.1.4.1"

wget -O mkcert https://github.com/FiloSottile/mkcert/releases/download/${MCVER}/mkcert-${MCVER}-linux-amd64

chmod +x mkcert

sudo mv mkcert /user/local/bin 

 Why This Matters 

 Using mkcert lets you emulate HTTPS in your local environment, which helps with catching mixed content issues, testing secure cookies, HSTS, etc., before you deploy to production.
