Never use 777 for directories on your live server, but on your own machine, sometimes we need to do more than 775, because 

<pre><code>chmod -R 775 storage
</code></pre>

Means

<pre><code>7 - Owner can write
7 - Group can write
5 - Others cannot write!
</code></pre>

If your webserver is not running as Vagrant, it will not be able to write to it, so you have 2 options:

<pre><code>chmod -R 777 storage
</code></pre>

or change the group to your webserver user, supposing it's <code>www-data</code>:

<pre><code>chown -R vagrant:www-data storage

You need to adjust the permissions of <code>storage</code> and <code>bootstrap/cache</code>.

<ul>
<li><code>cd</code> into your Laravel project. </li>
<li><code>sudo chmod -R 755 storage</code></li>
<li><code>sudo chmod -R 755 bootstrap/cache</code></li>
</ul>

You can try 777 if 755 doesn't work. 777 is not secure though!

Depending on how your web server is setup, you may be able to be more specific with your permissions, and only grant them to your web server user. Google <code>WEB SERVER NAME Laravel file permissions</code> for more information.

At the time of writing, this is for Laravel 5.4

Never set a directory to 777. you should change directory ownership. so set your current user that you are logged in with as owner and the webserver user (www-data, apache, ...) as the group.
You can try this:

<pre><code>sudo chown -R $USER:www-data storage
sudo chown -R $USER:www-data bootstrap/cache
</code></pre>

then to set directory permission try this:

<pre><code>chmod -R 775 storage
chmod -R 775 bootstrap/cache
</code></pre>

Update:

Webserver user and group depend on your webserver and your OS. to figure out what's your web server user and group use the following commands. for nginx use:

<code>ps aux|grep nginx|grep -v grep</code> 

for apache use:

<code>ps aux | egrep '(apache|httpd)'</code>

I wasn't too keen on changing my folder permissions to 777. Here's how I went about fixing this issue.

First, I changed the user who is running the web server on my local machine(I run nginx, but the principles apply everywhere):

<pre><code>$&gt; sudo vim /etc/nginx/nginx.conf
user &lt;my_user&gt; #inside nginx.conf
service nginx reload
</code></pre>

Afterwards, I created another <code>index.php</code> file under the <code>public/</code> folder to find out who was running my php-fpm version and where I would go about changing that:

<pre><code>&lt;?php
phpinfo();
?&gt;
</code></pre>

Reloading the page, I found out that <code>www-data</code> was the user(under the environment section). I also found out I was running php 7.1. I proceeded to change the user:

<pre><code>$&gt; sudo vim /etc/php/7.0/fpm/pool.d/www.conf 
#Look for www-data or the following variables: user, group, listen.user, listen.group.
</code></pre>

Finally, I gave the following permissions to folders:

<pre><code>sudo chmod -R 775 ./storage/
</code></pre>

Now, I made sure that I was the owner of the folders by using a simple:

<pre><code>ls -al
</code></pre>

If you set the server and php-fpm users to yourself and the folders are owned by root for example, then you will keep encountering this issue. This can happen if you did a <code>sudo laravel new &lt;project&gt;</code> as root. In that case, make sure you use a recursive <code>chown</code> command on your project to change the <code>user:group</code> settings. In most default cases, <code>www-data</code> is the main setting for the server and php, in that case it's a matter of making sure the folder isn't out of <code>www-data</code>'s reach.

My project is setup in my home directory. On Ubuntu 16.04 and Laravel 5.5.

For all Centos 7 users on a Laravel context, there is no need to disable Selinux, just run these commands:

semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/laravel/storage(/.*)?" # add a new httpd read write content to sellinux for the specific folder, -m for modify

Lastly, make sure your hosts, ips and virtual hosts are all correctly for remote accessing.

Selinux is intended to restrict access even to root users, so only the necessary stuff might be accessed, at least on a generalist overview, it's extra security, disabling it is not a good practise, there are many links to learn Selinux, but for this case it is not even required.

If you use cmd

<pre><code>sudo chown -R $USER:www-data storage
sudo chown -R $USER:www-data bootstrap/cache
</code></pre>

If you use GUI

First go to the project and right click on the storage and check the properties and go to the Permissions tab 

<a href="https://i.stack.imgur.com/Cb0bm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Cb0bm.png" alt="enter image description here"></a>

Change the permissions using below code

<pre><code>sudo chmod -R 777 storage
</code></pre>

Then your file properties may be

Then check your settings and execute laravel command it will work :)

In my particular case I had a config file generated and cached into the <code>bootstrap/cache/</code> directory so my steps where: 

<ol>
<li>Remove all generated cached files: <code>rm bootstrap/cache/*.php</code></li>
<li>Create a new <code>laravel.log</code> file and apply the update of the permissions on the file using: 

<ul>
<li><code>chmod -R 775 storage</code></li>
</ul></li>
</ol>

In Laravel, you should set ACL on <code>storage</code> and <code>cache</code> directory so that web server user can read/write on the directory. Open a new terminal and run following:

<pre><code>HTTPDUSER=$(ps axo user,comm | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1)

sudo setfacl -dR -m u:"$HTTPDUSER":rwX -m u:$(whoami):rwX bootstrap/cache storage/
sudo setfacl -R -m u:"$HTTPDUSER":rwX -m u:$(whoami):rwX bootstrap/cache storage/
</code></pre>

It might be late but may help someone, changing directory permissions worked for me.
Assuming that your Laravel project is in <code>/var/www/html/</code> directory. Goto this directory.
<pre><code>cd /var/www/html/
</code></pre>
Then change permissions of <code>storage/</code> and <code>bootstrap/cache/</code> directories.
<pre><code>sudo chmod -R 777 storage/
sudo chmod -R 777 bootstrap/cache/
</code></pre>

I stuck on this issue tried different commands but these will help to solve the problem

Hope it's helped others too.

Maximum people's are suggesting to change file permission 777 or 775, which I believe not an appropriate approach to solve this problem. You just need to change the ownership of <code>storage</code> and <code>bootstrap</code> folder.
In below Image you can see all my files/folder are under the root user(except storage and bootstrap, because I changed the ownership ),but I logged in as a administrator(before changing ownership) that's why it always giving permission denied. So I need to change the ownership of this two folder to administrator
<a href="https://i.stack.imgur.com/7L5GQ.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7L5GQ.png" alt="" /></a>
So how I did this,
go to your project directory and run below commands.
<code>sudo chown -R yourusername:www-data storage</code>,
<code>sudo chmod -R ug+w storage</code>,
<code>sudo chown -R yourusername:www-data bootstrap</code>,
<code>sudo chmod -R ug+w bootstrap</code>

I'm pretty new at laravel, in fact and I'm trying to create my very first project. for some reason I keep getting this error (I haven't even started coding yet)

<pre><code>Error in exception handler: The stream or file "/var/www/laravel/app/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied in /var/www/laravel/bootstrap/compiled.php:8423
</code></pre>

I've read this has something to do with permissions but <code>chmod -R 775 storage</code> didn't help at all.
