How to Enable exec() in PHP-FPM? 
 
Sometimes the exec() function is not working after turning on the PHP-FPM and in php configuration file we could not find any disable functions. If we turned off the PHP-FPM the exec function is working again. If you are facing such issues, please follow the below steps. 
 
 
 
First, you need to verify the PHP-FPM is enabled on the domain that facing the issue. Please follow the steps. 
 
1) Login to WHM. 
 
2) Navigate to MultiPHP Manager to check whether the domain is using PHP-FPM or not. 
 
3) From that page, you can verify that the domain is using PHP-FPM.

Now you have verified that PHP-FPM is on the server. So you need to follow the steps to enable exec() in PHP-FPM. 
 
1) Login to server via SSH. 
 
2) Check the PHP version of the server using the below command. 
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">#php -v</pre>
3) Then open the PHP-FPM configuration file. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">vi /opt/cpanel/ea-php70/root/etc/php-fpm.d/blah.domain.tld.conf</pre>
<div>
 </div>
4) Then you will find the exec() function in the disabled function list. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">php_admin_value[disable_functions] = passthru,shell_exec,system</pre>
5) Remove that from the above line. 
 
 
6) Then restart PHP-FPM using the below command. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">/scripts/restartsrv_apache_php_fpm</pre>
Now exec() should works. 
 
* You can also do the same by following below steps. 
 
 
1) Create the /var/cpanel/ApachePHPFPM directory using the below command: 
 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">mkdir /var/cpanel/ApachePHPFPM</pre>
<div>
 </div>
2) Create the /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml file 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">touch /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml</pre>
3) Open the file /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml using your text editor (e.g. vi, nano) : 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">vi /var/cpanel/ApachePHPFPM/system_pool_defaults.yaml</pre>
add the function that you want to disable. 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">php_admin_value_disable_functions : passthru,system</pre>
In this example, "passthru,system" are left as disabled functions. No other lines exist before or after this entry in this file. 
 
 
4) Regenerate the PHP-FPM configuration files via: 
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">/scripts/php_fpm_config –rebuild</pre>
Now exec() should works. 
 
 
Thanks

How to Install oVirt on CentOS 7

<div dir="ltr" style="text-align: left;" trbidi="on">
oVirt is an open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible. It was founded by Red Hat as a community project on which Red Hat Enterprise Virtualization is based. It allows centralized management of virtual machines, compute, storage and networking resources, from an easy-to-use web-based front-end with platform independent access. KVM on x86-64 and PPC architecture are the only hypervisors supported, but there is an ongoing effort to support ARM architecture in the future releases. .

Find files containing specific text in Linux</div>
 
Find files containing specific text using grep command 
grep is a command-line utility for searching plain-text data sets for lines that match a regular expression. Its name comes from the ed command g/re/p (globally search a regular expression and print), which has the same effect: doing a global search with the regular expression and printing all matching lines. Grep was originally developed for the Unix operating system, but later available for all Unix-like systems.

Find files containing specific text using grep command examples</div>
<div>
 </div>
<div>
In this example, we will search for 'PULSEAUDIO_SYSTEM_START' in all configuration files located in /etc directory.</div>
<div>
 </div>
<div>
Now there's a small problem, depending on your Linux distro, Find command Syntax can be slightly different.</div>
<div>
 </div>
<div>
*If you know the exact location and directory you're after, then use</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep "PULSEAUDIO_SYSTEM_START" /etc/default/pulseaudio 
PULSEAUDIO_SYSTEM_START=1
</pre>
<div>
*If you know the exact directory with the files containing that specific text, then use</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep "PULSEAUDIO_SYSTEM_START" /etc/default/*
grep: /etc/default/kdm.d: Is a directory
/etc/default/pulseaudio:PULSEAUDIO_SYSTEM_START=1
root@hackthesec:~#
</pre>
<div>
If you don't know the exact location of the file that contains the specific text you’re looking for, then you need to search all sub-directories recursively.</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep -r "PULSEAUDIO_SYSTEM_START" /etc/default/*
/etc/default/pulseaudio:PULSEAUDIO_SYSTEM_START=1
root@hackthesec:~#</pre>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep -R "PULSEAUDIO_SYSTEM_START" /etc/default/*
/etc/default/pulseaudio:PULSEAUDIO_SYSTEM_START=1
root@hackthesec:~#</pre>
</div>
<div>
Now what if you are searching through a massive file and there might be many outputs similar to what you’re looking for.. you might want to use --col flag to color code your output which searching files containing specific strings.</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep --col 'usb 1-1.4' /var/log/messages
Apr 4 09:14:25 kali kernel: [1191164.780496] usb 1-1.4: new low-speed USB device number 21 using ehci-pci
root@hackthesec:~#</pre>
</div>
<div>
Now I want to display all files with colorer output with containing specific text and instead of showing the whole content of the files</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep --col -r 'Linux version 3.14-kali1' /var/log/* | cut -d: -f1
/var/log/dmesg
/var/log/dmesg.0
/var/log/installer/syslog
root@hackthesec:~#</pre>
</div>
<div>
<div>
When you're using grep, depending on the commands used and permission you have on the system, you might see any of the following errors.</div>
<div>
 </div>
<div>
* Input/output error</div>
<div>
* recursive directory loop</div>
<div>
* No such file or directory</div>
<div>
* No such device or address</div>
<div>
* Permission denied</div>
<div>
 </div>
<div>
If you want to hide all errors or warning message spamming your output window(specifically useful when you're trying to use grep on a script) generated by the grep command, append 2>/dev/null to grep command. This will send and hide unwanted output to /dev/null device:</div>
</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep -R "PULSEAUDIO_SYSTEM_START" /etc/* 2>/dev/null 
/etc/default/pulseaudio:PULSEAUDIO_SYSTEM_START=1
/etc/init.d/pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/init.d/pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc0.d/K01pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc0.d/K01pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc1.d/K01pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc1.d/K01pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc2.d/S20pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc2.d/S20pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc3.d/S20pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc3.d/S20pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc4.d/S20pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc4.d/S20pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc5.d/S20pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc5.d/S20pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
/etc/rc6.d/K01pulseaudio:PULSEAUDIO_SYSTEM_START=0
/etc/rc6.d/K01pulseaudio:if [ "$PULSEAUDIO_SYSTEM_START" != "1" ]; then
root@hackthesec:~#</pre>
</div>
<div>
<div>
What if you're not sure about the case of the text you're after? You can use -i to ignore case.</div>
<div>
 </div>
<div>
Below example shows the difference between -i flag. First command didn’t find the text, second command did as we used -i flag to ignore case.</div>
</div>
<div>
<pre style="background: rgb(68, 67, 65); border-radius: 6px; border: 1px solid rgb(227, 227, 227); box-sizing: border-box; clear: none !important; margin-bottom: 10px !important; margin-top: 10px !important; overflow: auto; padding: 10px !important; width: auto !important; word-break: break-all;">root@hackthesec:~# grep -r "pulseaudio_system_start" /etc/default/*
root@hackthesec:~# 
root@hackthesec:~# grep -i -r "pulseaudio_system_start" /etc/default/*
/etc/default/pulseaudio:PULSEAUDIO_SYSTEM_START=1
root@hackthesec:~#</pre>
</div>
<div>
I always prefer using grep command with -r and --col flag in Debian Linux as -r complains less about permissions, files, directory etc. and of course some color helps on the eyes when you’re browsing through many lines.</div>

How to Install and Configure Nextcloud on CentOS 7 / RHEL 7

<div dir="ltr" style="text-align: left;" trbidi="on">
Install and Configure Nextcloud on CentOS / RHEL 7 
 
Nextcloud is functionally very similar to the widely used Dropbox, with the primary functional difference being that Nextcloud is free and open-source, and thereby allowing anyone to install and operate it without charge on a private server.  
 
In contrast to proprietary services like Dropbox, the open architecture allows adding additional functionality to the server in form of so-called applications.

Install Go 1.7 on Ubuntu 16.04 / 14.04 / CentOS 7 / Fedora 24 
 
Go (often referred to as golang) is a free and open source programming language created at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a compiled, statically typed language in the tradition of Algol and C, with garbage collection, limited structural typing, memory safety features and CSP-style concurrent programming features added. 
<div class="separator" style="clear: both; text-align: center;">

The language was announced in November 2009; it is used in some of Google's production systems,as well as by other firms. Two major implementations exist: Google's Go compiler, "gc", is developed as open source software and targets various platforms including Linux, OS X, Windows, various BSD and Unix versions, and since 2015 also mobile devices, including smartphones.A second compiler, gccgo, is a GCC frontend. The "gc" toolchain is self-hosting since version 1.7
