How to Install and use Log File Navigator – lnav in Ubuntu and CentOS linux

<h1 class="post-title entry-title" style="background-color: white; border: 0px; color: #155c8e; font-family: "Titillium Web", Arial, sans-serif; font-stretch: inherit; font-variant-numeric: inherit; font-weight: 400; letter-spacing: -1px; line-height: 1.3em; margin: 0px 0px 10px; padding: 0px; vertical-align: baseline; word-wrap: break-word;">
Install and use Log File Navigator – lnav in Ubuntu and CentOS</h1>
<div>
<div>
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. </div>
<div>
 </div>
<div>
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.</div>
<div>
 </div>
<div>
In this article we will show you how to install and use The Log File Navigator, lnav, on <a href="http://www.hackthesec.co.in/search/label/Ubuntu">Ubuntu </a>15.04/15.10/ and <a href="http://www.hackthesec.co.in/search/label/Centos">CentOS 7</a>.x</div>
</div>
<div>
 </div>
<div>
<div>
lnav – Features</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>

System Requirements 
 
Make sure that you complete the following tasks before you start the installation process: 
 
1. Setup Hostname 
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). 
 
You can use the following command for hostname setup eg. srv1.hackthesec.co.in 
 
hostname srv1.example.com 
2. Setup Server IP addresses 
Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information. 
 
3. Software Requirements 
You must have a clean/fresh installation of supported operating systems: 
CentOS 6, RedHat 6 or CloudLinux 6, MINIMAL installation and English version only! 
CentOS 7 is NOT supported. 
 
4. Hardware Requirements 
32 bit operating systems require a minimum of 512 MB RAM 
64 bit operating systems require a minimum of 1024 MB RAM (recommended) 
 
Recommended System: 4 GB+ RAM so you would have the full functionality such as Anti-virus scan of emails.

HOW TO INSTALL CWP 
 
 
Follow steps below to setup CentOS Web Panel on your server: 
 
Step 1 – Login to your server as root or as user with sudo privilege: 
 
Step 2 – Go to /usr/local/src directory and download CWP installer package there: 
<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>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjHCumkp8N-EKNmJ431ei3V3clDBLB5dOiXGEkVukFp8AuA1DkTgPzgkXZu0eo02G_UWvJW2IqvQxdpaWEB_WC9xIoE6NbIIA8-Zk4Vxi1o0pZrdbG3Y3W9hzsvhmTQ_7cyN-eodwOzKZax/s1600/cwp_download.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjHCumkp8N-EKNmJ431ei3V3clDBLB5dOiXGEkVukFp8AuA1DkTgPzgkXZu0eo02G_UWvJW2IqvQxdpaWEB_WC9xIoE6NbIIA8-Zk4Vxi1o0pZrdbG3Y3W9hzsvhmTQ_7cyN-eodwOzKZax/s1600/cwp_download.png" /></a></div>
 
Step 3 – Once downloaded, issue one simple command below to start the installer: 
<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>
The whole process is fully automatic. 
<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>
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: 
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjkppCekvY8ZZ1HJ79of1ohnaCKjLCcLOlyg0DvBBYrku-jq5nDkiw2HerQBKt4yWKg3FsdeQfdVztT3_DhfQLcF1vgZlGQS1zTYyrgiFSWtkZl9RkUA_kTbH5IkuWpuJcCDuhTCcZiC-nA/s1600/cwp-installed.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjkppCekvY8ZZ1HJ79of1ohnaCKjLCcLOlyg0DvBBYrku-jq5nDkiw2HerQBKt4yWKg3FsdeQfdVztT3_DhfQLcF1vgZlGQS1zTYyrgiFSWtkZl9RkUA_kTbH5IkuWpuJcCDuhTCcZiC-nA/s1600/cwp-installed.jpg" /></a></div>
 
Step 4 – Now hit Enter on your keyboard and your server should reboot automatically. Next time you try to login to your server via SSH, the display will be different. You will now see CWP welcome message. 
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjasChe2omZRknNfe_J0yitTgF1TyuoL4Qu90yMEXGfUh1Sj76zAOeh9TKNBkibQymExrUNUXraoajGTKC6lMSqHnH_6UTiBzVrbXm3mAGZYBTfCisNy2p7vY6XgLZPHMSQHeYx69jOTiB5/s1600/cwp-ssh.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjasChe2omZRknNfe_J0yitTgF1TyuoL4Qu90yMEXGfUh1Sj76zAOeh9TKNBkibQymExrUNUXraoajGTKC6lMSqHnH_6UTiBzVrbXm3mAGZYBTfCisNy2p7vY6XgLZPHMSQHeYx69jOTiB5/s1600/cwp-ssh.jpg" /></a></div>
Step 5 – Open up your favorite web browser (Firefox, Chrome, etc) and open your newly installed CWP admin GUI at one of these URLs: 
 
Log in to your CWP server using the link provided by the installer on your server 
CentOS WebPanel Admin GUI at http://SERVER-IP:2030/ 
Username: root 
Password: your root password 
 
- Setup nameservers 
- Setup shared ip (must be your public IP address) 
- Setup at least one hosting package (or edit default package) 
- Setup root email 
& now you are ready to host domains… 
 
For additional configuration instruction, please check our wiki/documentation site.

Atop – monitor system resources in Linux 
Atop is an ASCII full-screen performance monitor for Linux that is capable of reporting the activity of all processes (even if processes have finished during the interval), daily logging of system and process activity for long-term analysis, highlighting overloaded system resources by using colors, etc. At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks (including LVM) and network layers, and for every process (and thread) it shows e.g. the CPU utilization, memory growth, disk utilization, priority, username, state, and exit code. 
In combination with the optional kernel module netatop, it even shows network activity per process/thread. 
 
The command atop has some major advantages compared to other performance monitoring tools: 
 
<ul style="text-align: left;">
<li>Resource consumption by all processes</li>
<li>Utilization of all relevant resources</li>
<li>Permanent logging of resource utilization</li>
<li>Highlight critical resources</li>
<li>Scalable window width</li>
<li>Resource consumption by individual threads</li>
<li>Watch activity only</li>
<li>Watch deviations only</li>
<li>Accumulated process activity per user</li>
<li>Accumulated process activity per program</li>
<li>Network activity per process</li>
</ul>

Cacti allows a user to poll services at predetermined intervals and graph the resulting data. It is generally used to graph time-series data of metrics such as CPU load and network bandwidth utilization. A common usage is to monitor network traffic by polling a network switch or router interface via Simple Network Management Protocol (SNMP). 
 
The front end can handle multiple users, each with their own graph sets, so it is sometimes used by web hosting providers (especially dedicated server,virtual private server, and collocation providers) to display bandwidth statistics for their customers. It can be used to configure the data collection itself, allowing certain setups to be monitored without any manual configuration of RRDtool. Cacti can be extended to monitor any source via shell scripts and executables. 
 
Cacti can use one of two back ends: "cmd.php", a PHP script suitable for smaller installations, or "Spine" (formerly Cactid), a C-based poller which can scale to thousands of hosts.
