− | + | On Linux machines file permissions is a serious thing, Linux uses a mechanism to control what users can do an what they can not about folders, files and even the execution of applications, this mechanism consist in town set of parameters, the ownership and the permissions. | |
− | + | ==== Files and folders ownership ==== | |
− | + | Ownership have tow parameters the owner and group | |
− | + | The "owner" is who own the file or folder and it is represented by a "user name", in Linux a persons, applications and services use usernames, on most Linux distributions the Apache service runs under the user name "www-data". | |
− | + | The "group" is used to associate users into an logical group, this figure is useful when an administrator needs to grand or deny permissions to several users with one single command and not user by user. | |
− | + | ==== Files and folders permissions ==== | |
− | + | The permissions have three parameters that represents file and folder permissions for the owner, the group and others. the number goes from 0 to 7 and the following list explains what they means: | |
− | * | + | * 4 = permission to read |
+ | * 2 = permission to write | ||
+ | * 1 = permission to execute | ||
+ | * 0 = no permissions at all | ||
− | + | Note: "Others" represents everybody, this parameter is used to grant permission to everyone no matter the user they are or the group they belong to. This parameter should be set with care under certain situations grant incorrect permission to sensitive files and folders can cause security problems. | |

Introduction[edit]
This article provides detailed instructions for configuring a LAMPP server, not only for Joomla! it also should work fine for PHP development in general.
Theses instructions should work fine on any Debian based distribution such as Debian, Ubuntu, LinuxMint, Xubuntu, Kbuntu and others.
NOTE:To complement the security of your computer install a firewall to block external incoming traffic to your web service, you may also have to change some directives on your site configuration file to only serve request to the localhost address.
Installation[edit]
NOTE: You need a stable Internet connection for this tutorial, if you previously tried to install the LAMP stack and failed for any reason visit this page and follow the instruction here to delete any server configuration and start from scratch "How to remove the LAMP stack"
The installation of a LAMPP server on Linux is extremely easy, just follow this instructions:
- Open a terminal and type:
sudo apt-get install apache2 php5-mysql libapache2-mod-php5 mysql-server phpmyadmin php5-curl
- Say yes [Y] when the package manager ask you download and install the packages, this step will take some time depending on your connection speed
- At some point the installer will ask you for the MySQL root password use any password you like, but for this example we are going to use "myadmin"
- The installer will ask for "the web server that should be automatically configured to run phpmyadmin", press [spacebar] to choose "apache2" and press [enter], NOTE: make sure the selection is marked with and asterisk [*]
- The installer will ask for "Configure database for phpmyadmin with dbconfig-common", choose "<yes>" and press [enter]
- The installer will ask for "password of the database's administrative user", use any password you like, but for this example we are going to use "myadmin"
- The installer will ask for "mysql application password for phpmyadmin", use any password you like, but for this example we are going to use "myadmin"
- If no errors have being displayed then the installation is finish
1st test for Apache[edit]
- Open your web browser and type in the address bar "localhost" and press [enter]
- Normally Apache display a test page with some text like this:
It works! This is the default web page for this server. The web server software is running but no content has been added, yet.
1st test for PHP server[edit]
To test if PHP server is working lets create a quick test file using the command line
- Open a terminal and type
echo "<?php phpinfo(); ?>" | sudo tee /var/www/test.php
- Open your web browser and type in the address bar "localhost/test.php" and press [enter]
- The next thing you should see in your browser is a really long page displaying information about the PHP server, if not then something went wrong
- Now that we know the PHP server is working fine we don't need that test file anymore, type the following command in your terminal to delete the file
sudo rm /var/www/test.php
1st test for phpMyAdmin[edit]
- Open your web browser and type in the address bar "localhost/phpmyadmin" and press [enter]
- The next thing you should see is the phpMyadmin login page, if not then something went wrong, most likely you skip or not marked the option "apache2" at the question "web server that should be automatically configured to run phpmyadmin", to fix this problem just purge the installation and start over again the installation steps
- Login to phpmyadmin with the following credentials
- username = root
- password = myadmin
- You should be able to login normally and have no error messages at all
Understanding the folder structure[edit]
There are several folders and files that the LAMP server uses to store the configurations of the LAMP services and to store the files of your hosted websites
Apache default web site folder[edit]
Location: "/var/www/"
Description: by default the Apache server enables a test website and store the website files in that location, so every time you visit the page http://localhost, the browser display the page located at "/var/www/"
With your file browser navigate to "/var/www/" there should be a file called "index.html", change the content of the file for whatever you want and refresh the web page to see the changes.
Apache web sites configuration files[edit]
Location: "/etc/apache2/sites-available/"
Description: You can host multiples sites in the same server, this folder a configuration file for each site.
Apache configuration file[edit]
Location: "/etc/apache2/apache2.conf" Location: "/etc/apache2/envvars"
Description: This files contains very important information about the Apache service.
Apache ports configuration file[edit]
Location: "/etc/apache2/ports.conf"
Description: This files configure what port will Apache server listen to for http requests, by default http request are assigned to the port 80 but you can modify or add more ports.
Apache log files[edit]
Location: "/var/log/apache2/"
Description: That folder contain several files to keep track of several events on your Apache web server, such as errors in the services, errors in code of your site, failed authentication attempts and more, this is a good place to look at when something is not working file or you suspect some is trying to breach your server security
Configuration[edit]
Enabling mod_rewrite[edit]
The mod_rewrite module uses a rule-based rewriting engine, based on a PCRE regular-expression parser, to rewrite requested URLs on the fly. By default, mod_rewrite maps a URL to a filesystem path. However, it can also be used to redirect one URL to another URL, or to invoke an internal proxy fetch.
for more information visit http://httpd.apache.org/docs/current/mod/mod_rewrite.html
- open a terminal and type
sudo a2enmod rewrite
- now that the rewrite module is enabled we need to restart apache
sudo service apache2 restart
- done
Deploying a new site folder structure[edit]
By default the web server is hosting the files in the location "/var/www" but for security reason and for the sake of avoid ownership problems we are going to use another place to host our web site files
Lets create a new folder to store the web files and the log files of the site
- open a terminal and type
mkdir /home/youruser/lamp/ mkdir /home/youruser/lamp/public_html/ mkdir /home/youruser/lamp/logs/
NOTE: You can place your new site folders on any location you desire, this is just an example, replace "youruser" with your actual Linux username
To store the web site files we are going to use the folder "plublic_html" and for our log files we are going to use the folder "logs"
Creating the new site[edit]
To create and enable a new site in your server follow this steps:
NOTE: gedit is a common Linux editor but you can use any other alternative you like such as geany, nano, vim, pico, etc...
- open a terminal an type
sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/mydevsite
NOTE: "mydevsite" is the name of the new site used in this example, you can use any other name you like
- Open the site configuration
sudo gedit /etc/apache2/sites-available/mydevsite
- The content of that file should be something like this
<VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost>
- Make some modifications to make it looks like this, or simply copy and paste it
<VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /home/youruser/lamp/public_html <Directory /> Options FollowSymLinks AllowOverride All </Directory> <Directory /home/youruser/lamp/public_html> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride All Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /home/youruser/lamp/logs/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /home/youruser/lamp/logs/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride All Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost>
NOTE: Replace "youruser" with your current user name
- Save changes
- Now we need to enable the site, in a terminal type
sudo a2ensite mydevsite
- Lets disable the default site, we don't need it anymore
sudo a2dissite default
- Restart Apache to complete the process, in a terminal type
sudo service apache2 restart
- To test out our new site lets create a quick test file, in a terminal type
echo "<?php echo 'Hello world, today is is: '.date('Y/m/d'); ?>" | tee /home/youruser/lamp/public_html/today.php
NOTE: Replace "yourname" with your current user name
- Open your browser an navigate to "localhost/today.php"
- If everything is working ok you should see something like this
Hello world, today is is: 2012/05/05
Enabling additional ports[edit]
Note: If you have no plans to show your local site to another person over Internet just skip this section.
With the last configuration you should be able to access your page and access it from another computer connected to your LAN, if your computer is connected to Internet and also have assigned a Public IP you can access your site using that IP from any web browser, but for some reason some ISPs does not allow HTTP traffic (HTTP = port 80) over dynamic IPs, to solve this you just need to configure Apache to reply requests from a different port, in this case we are going to use the port number 8080 which is easy to remember.
If you are using a router to connect to Internet you should have to configure a port forwarding setting on your router to let other people see your local site, Google "how to do port forwarding" on your current router model. If you don't now what is the difference between a Static IP, Dynamic IP, Private IP and a Public IP we recommend you to do a Wikipedia reading about these topics.
- Open a terminal and type:
sudo gedit /etc/apache2/ports.conf
- Find the line "listen 80" and insert this line underneath
Listen 8080
- Save changes
- Open your new site configuration
sudo gedit /etc/apache2/sites-available/mydevsite
- Find this directive "<VirtualHost *:80>" and make the following modification
<VirtualHost *:80 *:8080>
- Save changes
- Restart Apache to complete the process, in a terminal type
sudo service apache2 restart
- To test your new configuration try to access your site from another computer over Internet, just type your IP in the browser's address bar and press enter, if the request fails try the new alternative port like this xxx.xxx.xxx.xxx:8080
Preventing ownership and permissions problems[edit]
On Linux machines file permissions is a serious thing, Linux uses a mechanism to control what users can do an what they can not about folders, files and even the execution of applications, this mechanism consist in town set of parameters, the ownership and the permissions.
Files and folders ownership[edit]
Ownership have tow parameters the owner and group
The "owner" is who own the file or folder and it is represented by a "user name", in Linux a persons, applications and services use usernames, on most Linux distributions the Apache service runs under the user name "www-data".
The "group" is used to associate users into an logical group, this figure is useful when an administrator needs to grand or deny permissions to several users with one single command and not user by user.
Files and folders permissions[edit]
The permissions have three parameters that represents file and folder permissions for the owner, the group and others. the number goes from 0 to 7 and the following list explains what they means:
- 4 = permission to read
- 2 = permission to write
- 1 = permission to execute
- 0 = no permissions at all
Note: "Others" represents everybody, this parameter is used to grant permission to everyone no matter the user they are or the group they belong to. This parameter should be set with care under certain situations grant incorrect permission to sensitive files and folders can cause security problems.
For example if we got a file with permissions like this "644", it means (owner=read+write)(group=read)(others=read)
To get more information about the Linux file systems and file permissions read this article.
Adding yourself to the Apache group and modifying permissions[edit]
For this example your username will be "youruser", on most Linux distributions the Apache service runs on the user "wwww-data" and the group "www-data", we need to include our user "youruser" in to the "www-data" group to be able to set permissions to the web server files and have no problems when we have to edit them.
- To add "youruser" to the Apache group, open a terminal and type
sudo adduser youruser www-data
- Now we need to change the owner and group of all our web server files to owner "www-data" and group "www-data"
sudo chown -R www-data:www-data /home/youruser/lamp/public_html
- Finally we have to set the correct folder permission so both APahce and our user can edit the files with no problems, on a terminal type
sudo chmod -R 775 /home/youruser/lamp/public_htm
Common problems and confusions[edit]
When Joomla creates files on extension installations or any other operation it uses the default mask 755 for folders and 644 for files, this permissions are correct and secure for production servers but it will give us problems on our local server because our editor will not be able to edit those files and folders. To fix this problems simple run again this tow commands.
sudo chown -R www-data:www-data /home/youruser/lamp/public_html
In the case you manually move files from your personal folders to the server web folder "public_html" those new files most likely will be owned by your username, this can cause problems if the server need to modify or delete information, to prevent this problem every time you move or copy information to your server web folder you ahve to set the correct owner and group for all those new files, open a terminal and run this command.
sudo chmod -R 775 /home/youruser/lamp/public_htm
Note: If your server have too many files this commands could be slow but you can always set a more specific path to apply permission in less files.
Other configurations[edit]
- open a terminal and type
sudo gedit /etc/php5/apache2/php.ini
- Find the line
output_buffering =
- Set the value to "= Off"
- Find the line
post_max_size =
- Set the value to "= 20M"
- Find the line
upload_max_filesize =
- Set the value to "= 20M"
- Save changes
- Type in your terminal
sudo service apache2 restart
Enforcing security[edit]
Since your computer is now running web services, this services are listening for requests and will reply to anyone who have the correct IP and port, in other words other people in your LAN and Internet can access your local site without your permission or they can even try to crack/hack your workstation. To prevent this you just need to install a firewall and "deny" by default any external incoming requests to your computer.
For Linux users there is a nice and simple firewall called "Uncomplicated Firewall" to install the user interface and manage the firewall from your desktop just follow these steps
- open a terminal and type:
sudo apt-get install gufw
Note: you can also install the application from the software center
- Open the application when the installation finishes
- Press the "unlock" button and type your administrative password
- Make sure "status = On" and "Incoming = Deny" leave the rest in their default values
- To test your firewall just try to connect to your local site from a local computer on your LAN or a remote computer over Internet when the firewall status is "Status = On", your shouldn't be able to connect whatsoever
- Now "temporally" change the status of your firewall to "Status = Off" and try to connect again, people should be able to see your local site just fine, remember to set "Status = On" after this test
Note: In this tutorial we are denying any incoming external requests to any port, as a side note you can also Deny all incoming requests and manually allow incoming requests to few specific ports if you wish, but that kind of settings are up to you, since a PC workstation is not a server is ok to deny all incoming traffic by default
