<div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">The Log File Navigator, lnav, is an enhanced log file viewer that takes advantage of any semantic information that can be gleaned from the files being viewed, such as timestamps and log levels. </span></span></div>
<div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span></div>
<div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Using this extra semantic information, lnav can do things like interleaving messages from different files, generate histograms of messages over time, and providing hotkeys for navigating through the file. It is hoped that these features will allow the user to quickly and efficiently zero in on problems.</span></span></div>

<b><u><span style="color: #0b5394;">lnav – Features</span></u></b></div>
<div style="color: #333333;">
<ul style="text-align: left;">
<li>Single log view: all log file contents are merged into a single view based on message timestamps. No need to manually correlate timestamps across multiple windows or figure out the order in which to view rotated log files.</li>
<li>Automatic format detection for several common log files. It also detects gzip/bzi2 files and decompress them automatically on the fly.</li>
<li>Filters: display only lines that match or do not match a set of regular expressions. Filter by error level.</li>
<li>Timeline view: shows a histogram of messages over time. The number of warnings and errors are highlighted in the display so that you can easily see where problems have occurred.</li>
<li>Query logs using SQL: log files are directly used as the backing for SQLite virtual tables.</li>
<li>Automatic data extraction: built-in log message parser can automatically discover and extract interesting data from plainly formatted log messages.</li>
<li>Live operation: Search as you type. New log lines are automatically loaded and searched as they are added; filters apply to lines as they are loaded; and, SQL queries are checked for correctness as you type.</li>
<li>Syntax highlighting with configurable colourizing</li>
<li>Tab completion</li>
<li>Sessions</li>
<li>Supports Linux and Mac</li>
</ul>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><b><u>System Requirements</u></b></span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Make sure that you complete the following tasks before you start the installation process:</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">1. Setup Hostname</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">This hostname cannot be the same as any domain that is on your server (for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname).</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">You can use the following command for hostname setup eg. srv1.hackthesec.co.in</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">hostname srv1.example.com</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">2. Setup Server IP addresses</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information.</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">3. Software Requirements</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">You must have a clean/fresh installation of supported operating systems:</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">CentOS 6, RedHat 6 or CloudLinux 6, MINIMAL installation and English version only!</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">CentOS 7 is NOT supported.</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">4. Hardware Requirements</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">32 bit operating systems require a minimum of 512 MB RAM</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">64 bit operating systems require a minimum of 1024 MB RAM (recommended)</span></span><br />
<br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Recommended System: 4 GB+ RAM so you would have the full functionality such as Anti-virus scan of emails.</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Follow steps below to setup CentOS Web Panel on your server:</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Step 1 – Login to your server as root or as user with sudo privilege:</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Step 2 – Go to /usr/local/src directory and download CWP installer package there:</span></span><br />
<pre style="background: rgb(68, 68, 68); border-radius: 3px; border: 1px solid rgb(221, 221, 221); color: white; font-family: "Courier 10 Pitch", Courier, monospace; font-size: 15px; font-stretch: inherit; line-height: 19px; margin-bottom: 30px; margin-top: 30px; max-width: 100%; overflow-x: auto; overflow-y: hidden; padding: 18px 20px; vertical-align: baseline; word-wrap: normal;">cd /usr/local/src
wget http://centos-webpanel.com/cwp-latest</pre>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Step 3 – Once downloaded, issue one simple command below to start the installer:</span></span><br />
<pre style="background: rgb(68, 68, 68); border-radius: 3px; border: 1px solid rgb(221, 221, 221); color: white; font-family: "Courier 10 Pitch", Courier, monospace; font-size: 15px; font-stretch: inherit; line-height: 19px; margin-bottom: 30px; margin-top: 30px; max-width: 100%; overflow-x: auto; overflow-y: hidden; padding: 18px 20px; vertical-align: baseline; word-wrap: normal;">sh cwp-latest</pre>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">The whole process is fully automatic.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgSopw4SkzWe3Riuuzsz4sTRkinxzg3T2tQJHOss3rsWUG3oT5LWdHnoBx1yCMmgmt9eruHb3iFQ7nbCgv_j8iVsv1vTy0KbZfEg82frn6Rbs6sekewbh_4CQgOxRPaJRDr5LaIYF9p_-Ct/s1600/cwp-install-process.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgSopw4SkzWe3Riuuzsz4sTRkinxzg3T2tQJHOss3rsWUG3oT5LWdHnoBx1yCMmgmt9eruHb3iFQ7nbCgv_j8iVsv1vTy0KbZfEg82frn6Rbs6sekewbh_4CQgOxRPaJRDr5LaIYF9p_-Ct/s1600/cwp-install-process.jpg" /></a></div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">The CWP installation progress will take some times because several software will be compiled from source (especially PHP) for improved performance, security and flexibility. In my case it is almost like installing WHM/cPanel.Once the process is done, you’ll see something like this:</span></span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;"><br /></span></span>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px;">Step 4 – Now hit Enter on your keyboard and your server should reboot automatically.

<div>
<div>
<span style="font-family: Open Sans;"><span style="font-size: 14px;">The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors.</span></span></div>
<div>
<span style="font-family: Open Sans;"><span style="font-size: 14px;"><br /></span></span></div>
<div>
<span style="font-family: Open Sans;"><span style="font-size: 14px;">The modules can be downloaded from metacpan.org as well as mirrored sites worldwide.CPAN can denote either the archive network itself, or the Perl program that acts as an interface to the network and as an automated software installer (somewhat like a package manager). Most software on CPAN is free and open source software.</span></span></div>

This is very simple for one module with no dependencies. Typically, Perl modules will be dependent on several other modules. Chasing all these dependencies one-by-one can be very painful and annoying task. I recommend the CPAN method of installation as shown below. Use the manual method only if the server is not connected to the Internet.</div>

To install Perl modules using CPAN, make sure the cpan command is working. You should have the CPAN perl module installed before you can install any other Perl modules using CPAN. In this example, CPAN module is not installed.</div>

Select the global configuration directory [/etc/automysqlbackup]:
Select directory for the executable [/usr/local/bin]:

<div>
Next, we have to configure AutoMySQLBackup. Open its configuration file located in the directory we set when we ran the installation script.</div>
