Forbidden 403 error when trying to access Apache 2.4.7 web server in browser

When I access Apache web server using localhost from same web server PC, it shows Apache2 Ubuntu default page.

But when I access Apache web server using 192.168.0.2, it is giving 403 Forbidden error (Forbidden You don't have permission to access / on this server).

Web Server details

• Ubuntu 14.04 LTS
• Apache version 2.4.7

Ownership Commands

www-data sudo adduser ftpuser www-data sudo chown -R www-data:ftpuser /var/www sudo chmod -R g+rwX /var/www 

In etc/apache2/apache2.conf file

ServerName 192.168.0.2 <Directory/> AllowOverride All Require all granted </Directory> 

In etc/apache2/port.conf file

NameVirtualHost *:80 Listen *:80 

Virtual Host for one website

<VirtualHost *:80> ServerName mysite DocumentRoot /var/www/mysite <Directory /var/www/mysite> Options None FollowSymLinks AllowOverride None Require all granted </Directory> </VirtualHost> 

What settings do I need to do at which place? Please help...

1. You should configure your /etc/hosts file like that:

127.0.0.1 localhost 127.0.0.1 test-site 127.0.1.1 my-hostname # The following lines are desirable for IPv6 capable hosts. etc... 

Where test-site is the second "localhost". And my-hostname is the "System hostname" defined in /etc/hostname.

2. You should define and enable a Virtual Host (VH):

There is a default HTTP VH. It's placed in /etc/apache2/sites-available/. The filename is 000-default.conf. You have to edit it (you can rename it, if you want, or make some other .conf files, based on it) and after that you have to enable it.

You can enable it manually through creation of "soft, symbolic link":

sudo ln -s /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-enabled/ 

Or you can use Apache2 tool called a2ensite, which make the same:

sudo a2ensite 000-default.conf 

Let's assume there has 3 Virtual Hosts, enabled SSL, and registered private domain (SOS.info for an example):

/etc/apache2/sites-available/http.SOS.info.conf /etc/apache2/sites-available/https.SOS.info.conf 

And one which is created for the purposes of this topic:

/etc/apache2/sites-available/http.test-site.conf 

The content of First 2 VHs is:

$ cat /etc/apache2/sites-available/http.SOS.info.conf

<VirtualHost *:80> ServerName SOS.info ServerAlias ServerAdmin # Redirect Requests to SSL Redirect permanent "/" "" ErrorLog ${APACHE_LOG_DIR}/http.SOS.info.error.log CustomLog ${APACHE_LOG_DIR}/http.SOS.info.access.log combined </VirtualHost> 

^{This one redirects all HTTP requests to HTTPS.}

$ cat /etc/apache2/sites-available/https.SOS.info.conf

<IfModule mod_ssl.c> <VirtualHost _default_:443> ServerName SOS.info ServerAlias ServerAdmin DocumentRoot /var/www/html SSLEngine on SSLCertificateFile /etc/ssl/certs/SOS.info.crt SSLCertificateKeyFile /etc/ssl/private/SOS.info.key SSLCertificateChainFile /etc/ssl/certs/SOS.info.root-bundle.crt #etc.. </VirtualHost> </IfModule> 

^{This is the HTTPS VH.}

The content of these two files can be posted in one file, but in this case their management (a2ensite/a2dissite)will be more difficult.

The third Virtual Host is that, which is created for our purposes:

$ cat /etc/apache2/sites-available/http.test-site.conf

<VirtualHost *:80> ServerName test-site ServerAlias test-site.SOS.info DocumentRoot /var/www/test-site DirectoryIndex index.html ErrorLog ${APACHE_LOG_DIR}/test-site.error.log CustomLog ${APACHE_LOG_DIR}/test-site.access.log combined <Directory /var/www/test-site> # Allow .htaccess AllowOverride All Allow from All </Directory> </VirtualHost> 

3. With this configuration you should access:

 # pointed to the directory of the mine Domain # iin our case: /var/www/html (SOS.info), but you should get an error, because the SSL certificate # which redirects to # you should have valid SSL certificate # which is allied to and redirects to # which is allied to 

On the main example you should access and:

 # pointed to the directory /var/www/test-site # which is allied to 

Try to open the site in the web browser or just try (in the terminal) with next commands:

$ curl -L $ curl -L 

^{Of course, you need to have some index.html pages in their DocumentRoot :)}

I will leave next notes by reason of pedantry :)

4. You need properly configured `/etc/apache2/apache2.conf`.

Ii is good idea to spend some time to improve your server's security. These manuals are about the security configuration: 1st and 2nd. Here you can get free SSL certificate. These sites will help you to check your progress: 1st and 2nd.

According to above security manuals /etc/apache2/apache2.conf file must looks like:

Mutex file:${APACHE_LOCK_DIR} default PidFile ${APACHE_PID_FILE} Timeout 60 #KeepAlive Off KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 5 HostnameLookups Off ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn IncludeOptional mods-enabled/*.load IncludeOptional mods-enabled/*.conf Include ports.conf <Directory /> Options None FollowSymLinks AllowOverride None Require all denied </Directory> <Directory /var/www/> Options None FollowSymLinks AllowOverride None Require all granted </Directory> AccessFileName .htaccess <FilesMatch "^\.ht"> Require all denied </FilesMatch> LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent IncludeOptional conf-enabled/*.conf IncludeOptional sites-enabled/*.conf # Hide Server type in the http error-pages ServerSignature Off ServerTokens Prod # Etag allows remote attackers to obtain sensitive information FileETag None # Disable Trace HTTP Request TraceEnable off # Set cookie with HttpOnly and Secure flag. # a2enmod headers Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure # Clickjacking Attack Header always append X-Frame-Options SAMEORIGIN # CX-XSS Protection Header set X-XSS-Protection "1; mode=block" # Disable HTTP 1.0 Protocol RewriteEngine On RewriteCond %{THE_REQUEST} !HTTP/1.1$ RewriteRule .* - [F] # Change the server banner @ ModSecurity # Send full server signature so ModSecurity can alter it ServerTokens Full # Alter the web server signature sent by Apache <IfModule security2_module> SecServerSignature "Apache 1.3.26" </IfModule> Header set Server "Apache 1.3.26" Header unset X-Powered-By # Hde TCP Timestamp # gksu gedit /etc/sysctl.conf # >> net.ipv4.tcp_timestamps = 0 # Test: sudo hping3 SOS.info -p 443 -S --tcp-timestamp -c 1 # Disable -SSLv2 -SSLv3 and weak Ciphers SSLProtocol all -SSLv2 -SSLv3 SSLHonorCipherOrder on SSLCipherSuite "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA EECDH EDH+aRSA !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS !RC4" 

5. Set up the Firewall.

To allow/deny external access to your web server you can use UFW (Uncomplicated Firewall):

sudo ufw allow http sudo ufw allow https 

To allow only tcp protocol use:

sudo ufw allow http/tcp sudo ufw allow https/tcp 

You can use and the port number directly:

sudo ufw allow 80/tcp sudo ufw allow 443/tcp 

Just in case you can reload the "rules table":

sudo ufw reload 

You can use and UFW's GUI interface, called gufw.

sudo apt update sudo apt install gufw gufw & 

_{Choice the Office profile. It will set: Status:ON, Incoming:Deny and Outgoing:Allow and add your rules.}

6. If you have a router don't forget to forward some ports:

If you have a router and you want your web server to be accessible from Internet, don’t forget to add some port forwarding. Something like this.

Please change the ownership of the directory where you're serving your files from using command:

sudo chown -R www-data:www:data <directory_where_you_serve_files_from> 

I am supposed to link you to this answer where solved my problem.

First of all, add permissions to the folder:

sudo chmod -R 775 /var/www 

Then add this text:

<Directory /var/www/html> AllowOverride All </Directory> 

To the end of this file:

/etc/apache2/sites-available/000-default.conf
