This article shows you how to install\u00a0VnStat<\/strong>\u00a0and\u00a0VnStat PHP<\/strong>\u00a0 in Linux systems.<\/p>\n

VnStat PHP Prerequisites<\/h3>\n

You need to install the following software packages on your system.<\/p>\n

    \n
  1. VnStat<\/strong>\u00a0: A command-line network bandwidth monitoring tool, must be installed, configured and should collect network bandwidth statistics.<\/li>\n
  2. Apache<\/strong>\u00a0: A Web Server to serve web pages.<\/li>\n
  3. PHP 5<\/strong>\u00a0: A server-side scripting language for executing php scripts on the server.<\/li>\n
  4. php-gd extension<\/strong>\u00a0: A GD extension for serving graphic images.<\/li>\n<\/ol>\n

    Step 1: Installing and Configuring VnStat Command Line Tool<\/h3>\n

    VnStat<\/strong>\u00a0is an command line network bandwidth monitoring utility which counts bandwidth (transmit<\/strong>\u00a0and\u00a0received<\/strong>) on network devices and keeps the data in its own database.<\/p>\n

    Vnstat<\/strong>\u00a0is a third party tool and can be installed via\u00a0enabling epel repository<\/a>\u00a0under\u00a0Red Hat<\/strong>\u00a0based systems. Once you\u2019ve enabled, you can install it using\u00a0yum command<\/strong>\u00a0as shown below.<\/p>\n

    On RHEL\/CentOS and Fedora<\/h5>\n
    # yum install vnstat<\/pre>\n
    On Debian\/Ubuntu and Linux Mint<\/h5>\n
    Debian<\/strong>\u00a0user\u2019s simply\u00a0apt-get<\/strong>\u00a0to install<\/p>\n
    $ sudo apt-get install vnstat<\/pre>\n
    As I said\u00a0Vnstat<\/strong>\u00a0maintains its own database to keep all network information. To create new database for network interface called \u201ceth0<\/strong>\u201c, issue the following command. Make sure to replace interface name as per your requirements.<\/p>\n
    # vnstat -i eth0\r\n\r\nError: Unable to read database \"\/var\/lib\/vnstat\/eth0\".\r\nInfo: -> A new database has been created.<\/pre>\n
    If you get above error, don\u2019t worry about such error, because you are executing the command first time. So, its creates new database for\u00a0eth0<\/strong>.<\/p>\n
    Now run following command to update all enabled databases or only specific interface with\u00a0-i<\/strong>\u00a0parameter as shown. It will generate traffic statistics of\u00a0IN<\/strong>\u00a0and\u00a0OUT<\/strong>\u00a0of a\u00a0IN<\/strong>\u00a0and\u00a0OUT<\/strong>\u00a0of a eth0 interface.<\/p>\n
    # vnstat -u -i eth0<\/pre>\n
    Next, add a crontab that runs every\u00a05min<\/strong>\u00a0and update\u00a0eth0<\/strong>\u00a0database to generate traffic statistics.<\/p>\n
    *\/5 * * * * \/usr\/bin\/vnstat -u >\/dev\/null 2>&1<\/pre>\n
    Step 2: Installing Apache, Php and Php-gd Extension<\/h3>\n
    Install the following software packages with the help of package manager tool called \u201cyum<\/strong>\u201d for\u00a0Red Hat<\/strong>\u00a0based systems and \u201capt-get<\/strong>\u201d for\u00a0Debian<\/strong>\u00a0based systems.<\/p>\n
    On RHEL\/CentOS and Fedora<\/h5>\n
    # yum install httpd php php-gd<\/pre>\n
    Turn on\u00a0Apache<\/strong>\u00a0at system start-up and start the service.<\/p>\n
    # chkconfig httpd on\r\n# service httpd start<\/pre>\n
    Run the following \u201ciptables<\/strong>\u201d command to open Apache port \u201c80<\/strong>\u201d on firewall and then restart the service.<\/p>\n
    # iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT\r\n# service iptables restart<\/pre>\n
    On Debian\/Ubuntu and Linux Mint<\/h5>\n
    $ sudo apt-get install apache2 php5 php5-gd<\/pre>\n
    $ sudo \/etc\/init.d\/apache2 start<\/pre>\n
    Open port\u00a080<\/strong>\u00a0for Apache.<\/p>\n
    $ sudo ufw allow 80<\/pre>\n
    Step 3: Downloading VnStat PHP Frontend<\/h3>\n
    Download latest\u00a0VnStat PHP<\/strong>\u00a0source tarball file using \u201cwget command<\/a>\u201d as shown below or visit\u00a0THIS PAGE<\/a>\u00a0to grab latest version.<\/p>\n
    # cd \/tmp\r\n# wget http:\/\/www.sqweek.com\/sqweek\/files\/vnstat_php_frontend-1.5.1.tar.gz<\/pre>\n
    Extract the source tarball file, using \u201ctar command<\/a>\u201d as shown given.<\/p>\n
    # tar xvf vnstat_php_frontend-1.5.1.tar.gz<\/pre>\n
    Step 4: Installing VnStat PHP Frontend<\/h3>\n
    Once extracted, you will see a directory called \u201cvnstat_php_frontend-1.5.1<\/strong>\u201c. Copy the contents of this directory to web server root location as directory\u00a0vnstat<\/strong>\u00a0as shown below.<\/p>\n
    On RHEL\/CentOS and Fedora<\/h5>\n
    # cp -fr vnstat_php_frontend-1.5.1\/ \/var\/www\/html\/vnstat<\/pre>\n
    If\u00a0SELinux<\/strong>\u00a0enabled on your system, run the \u201crestorecon<\/strong>\u201d command to restore files default\u00a0SELinux<\/strong>\u00a0security contexts.<\/p>\n
    # restorecon -Rv \/var\/www\/html\/vnstat\/<\/pre>\n
    On Debian\/Ubuntu and Linux Mint<\/h5>\n
    # cp -fr vnstat_php_frontend-1.5.1\/ \/var\/www\/vnstat<\/pre>\n
    Step 5: Configuring VnStat PHP Frontend<\/h3>\n
    Configure it to match your setup. To do open the following file with\u00a0VI<\/strong>\u00a0editor and change the parameters as shown below.<\/p>\n
    On RHEL\/CentOS and Fedora<\/h5>\n
    # vi \/var\/www\/html\/vnstat\/config.php<\/pre>\n
    On Debian\/Ubuntu and Linux Mint<\/h5>\n
    # vi \/var\/www\/vnstat\/config.php<\/pre>\n
    Set your default\u00a0Lagrange<\/strong>.<\/p>\n
    \/\/ edit these to reflect your particular situation\r\n$locale = 'en_US.UTF-8';\r\n$language = 'en<\/strong>';<\/pre>\n
    Define your network interfaces to be monitored.<\/p>\n
    \/\/ list of network interfaces monitored by vnStat\r\n$iface_list = array('eth0<\/strong>', 'eth1<\/strong>');<\/pre>\n
    You can set custom names for your network interfaces.<\/p>\n
    \/\/ optional names for interfaces\r\n\/\/ if there's no name set for an interface then the interface identifier.\r\n\/\/ will be displayed instead\r\n$iface_title['eth0'] = 'Internal<\/strong>';\r\n$iface_title['eth1'] = 'External<\/strong>';<\/pre>\n
    Save and close the file.<\/p>\n
    Step 6: Access VnStat PHP and View Graphs<\/h3>\n
    Open your favourite browser and navigate to any of the following link. Now you will see a fancy network graphs that shows you a summary of network bandwidth usage in\u00a0hours<\/strong>,\u00a0days<\/strong>\u00a0and\u00a0months<\/strong>.<\/p>\n
    http:\/\/localhost\/vnstat\/\r\nhttp:\/\/your-ip-address\/vnstat\/<\/pre>\n
