Protect .env file in Laravel project in the testing server

March 4, 2019

Problem: In the testing server, the .env file is viewable (e.g ip/laravel_project/.env), people can view all the sensitive data like DB username and password.

The original solution is worked. All you need to do is change the .env file permission to 640. Then generate the Application Encryption Key again:

php artisan key:generate
php artisan config:cache

Solution: Change .env file permission while not affecting Laravel running

sudo chmod 640 .env
php artisan key:generate
php artisan config:cache

Put the hosting directory into /var/www but not /var/www/html, so that user can not access through http://IP/project_name/public/ but to domain name. You can also Restrict directory access in Apache by allow some ip only in order to protect .env file and other sensitive information.

“WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!” occurred when trying to connect server via SSH

March 2, 2019

Problem: Use SSH to connect the server as usual, then occur “WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!“ message

The target server is re-format before, the authentication information has been changed. You have to delete the old authentication information in your computer first.

Solution:

Linux:

ssh-keygen -R (target server IP)

Windows:

Go to the host key directory, in my case the directory is “C:\Users\paulck.ssh”. Find the known_hosts file, delete the line that contains target server IP.

(target server IP) ecdsa-sha2-nistp256 (RSA key)
