Laravel: Can’t create Syslink for Laravel on shared hosting
If you are trying to do a storage link using php artisan storage:link but you got an error like: no such file or directory
one reason for that is a wrong path, so to solve this you can do the link manually, all you have to do is to write this command:
ln -s /home/yourSite/yourLaravelFolder/storage/app/public /home/yourSite/public_html
where the first path is the source folder and the second path is the target which is usually referred to public_html folder. Note that you have to change the path according to your web site
Password protect a folder in xampp
Here is how to protect a folder with username and password in xampp :
- Open the command promote
- Go to your xampp folder and then go to: /apache/bin/
- Run this command :
htpasswd.exe -c -b .htpasswd my_user _name my_password
Don’t forget Change “my_user_name” and “my_password” - A file with the name of .htpasswd will be created at the folder of /apache/bin
- Create a file with the name of : .htaccess at the folder you want to protect ( don’t forget the dot in .htaccess)
- Write the following in the .htaccess file:
AuthType Basic
AuthName “v3d”
AuthUserFile “c:/xampp/apache/bin/.htpasswd”
require valid-user
Note that the path in AuthUserFile line (c:/xampp/apache/bin/.htpasswd) is the path to your xampp folder where the .htpasswd file is created, very important to keep this file away from the httdocs folder.

How to put Magento 2 in maintenance mode
Even I think this should be a simple checkbox in Magento Control Panel but the most simple way I found is to put a file in var folder with the name of: var/.maintenance.flag
If you want to allow an ip or a group of ips you simply write this list of ips in a file: var/.maintenance.ip
Of course if you have access to CLI you can just type:
bin/magento maintenance:enable –ip=1.2.3.4
where –ip=1.2.3.4 is the ip that can access the website normally ..
if you use a shared hosting, to run the above command you have to go to the public_html folder first :
cd public_html
and then run the command using php
php bin/magento maintenance:enable –ip=1.2.3.4
