Hey,
So to do the reinstall of xe-linux-distribution you need this link.
http://e584a326fabd876c3b87-5cc4f7b75bc093abc6d4ecc36a7bc696.r2.cf1.rackcdn.com/xs-tools-6.2.0.zip
Unzip it, there is a linux folder and the binary installers are in there.
Installing Ioncube Zend Extension for PHP
A lot of customers note that sometimes, the exact version of ioncube is not available for their specific version of PHP in their repository for their OS.
This isn’t really a big deal, and is actually something that can be manually installed.
cd ~ _php=$(php -r "echo PHP_MAJOR_VERSION.'.'.PHP_MINOR_VERSION;"); echo $_php wget http://downloads3.ioncube.com/loader_downloads/ioncube_loaders_lin_x86-64.tar.gz tar -zxf ioncube_loaders_lin_x86-64.tar.gz ioncube/ioncube_loader_lin_$_php.so chown -R root. ioncube \mv ioncube/ioncube_loader_lin_$_php.so /usr/lib64/php/modules/ echo "zend_extension=/usr/lib64/php/modules/ioncube_loader_lin_$_php.so" > /etc/php.d/01a-ioncube-loader.ini
Thanks to Alex Drapkin for this.
How To Enable GZIP Compression/mod_deflate in Apache
This is something quite easy to do.
Check that the deflate module is installed
# apachectl -M | grep deflate deflate_module (shared) Syntax OK
Check the content encoding is enabled by using curl on the site
# curl -I -H 'Accept-Encoding: gzip,deflate' http://somewebsite.com/ HTTP/1.1 200 OK Date: Fri, 23 Jan 2017 11:02:16 GMT Server: Apache X-Pingback: http://somewebsite.com/somesite.php X-Powered-By: rabbits Connection: close Content-Type: text/html; charset=UTF-8
Create a file called /etc/httpd/conf.d/deflate.conf
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
DeflateCompressionLevel 8
</ifmodule>
Restart apache2
/etc/init.d/httpd reload Reloading httpd:
retest the gzip content-encoding directive with curl using Accept-Encoding: gzip directive.
# curl -I -H 'Accept-Encoding: gzip,deflate' http://somesite.com/ HTTP/1.1 200 OK Date: Fri, 25 Sep 2015 00:04:26 GMT Server: Apache X-Pingback: http://somesite.com/somesite.php X-Powered-By: muppets Vary: Accept-Encoding Content-Encoding: gzip <---- this line indicates that compression is active Content-Length: 20 Connection: close Content-Type: text/html; charset=UTF-8

Converting a Website from mod_php 5.6.29 to php56u-fpm-httpd
So a customer wanted us to convert their PHP site to use the php-fpm. The reason was, that php-fpm can run as it’s own user and group, and isn’t limited in it’s execution in the same way that apache is on the filesystem with the regular version of php.
This is how I achieved it.
yum install php-fpm.x86_64 php56u-fpm-httpd.noarch # for some reason if you get a weird error install them seperately yum install php-fpm.x86_64 yum install php56u-fpm-httpd.noarch
Then you will need to run the following:
systemctl enable php-fpm systemctl enable httpd systemctl start php-fpm # check the status systemctl status php-fpm
If necessary like it was for me change /etc/php-fpm.d/www.conf to reflect the following
listen = /var/run/php-fpm/default.sock listen.owner = apache listen.group = apache listen.mode = 0660 # Also make sure you set the correct execution group, the listen socket perms are different # as I have found out from experience ; Unix user/group of processes ; Note: The user is mandatory. If the group is not set, the default user's group ; will be used. user = sftpusercangohere group = apache
If necessary, you will want to use a Custom user/group for php-fpm. This is one of the advantages of using FPM.
Also, you can use EVENT MPM instead of PREFORK MPM, it’s more efficient with fpm, and certainly worth considering. This step is optional, and not required for fpm to work
# Comment out this line #LoadModule mpm_prefork_module modules/mod_mpm_prefork.so #Uncomment the following LoadModule mpm_event_module modules/mod_mpm_event.so
Edit your httpd.conf file in /etc/htpd/conf.d/* or /etc/httpd/httpd.conf and ensure in side the Virtualhost directive you have the following set:
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/vhosts/yourwebsite.com/html/$1
Where html is the documentroot of the site.
This article is kind of complete but still a bit drafty.
Checking Webserver Logs and generating hit counts
So, I’ve been meaning to do this for a while. I’m sure your all familiar with this crappy oneliner where you’ll check the hits using wc -l against a webserver log for a given hour and use for i in seq or similar to get the last 10 minutes data, or the last 59 minutes. But getting hours and days is a bit harder. You need some additional nesting, and, it isn’t difficult for you to do at all!
for i in 0{1..9}; do echo "16/Jan/2017:06:$i"; grep "16/Jan/2017:06:$i" /var/log/httpd/soemsite.com-access_log | wc -l ; done
I improved this one, quite significantly by adding an additional for j, for the hour, and adding an additional 0 in front of {1..9}, this properly is matching the Apache2 log format and allows me to increment through all the hours of the day. to present ;-D All that is missing is some error checking when the last date in the file is, im thinking a tail and grep for the timecode from the log should be sufficient.
Here is the proud oneliner I made for this!
for j in 0{1..9}; do for i in 0{1..9} {10..59}; do echo "16/Jan/2017:$j:$i"; grep "16/Jan/2017:06:$i" /var/log/httpd/website.com-access_log | wc -l ; done; done
Tracing Down Network and Process Traffic Using Netfilter
Every now and then at Rackspace, as with any hosting provider. We do occasionally have issues where customers have left themselves open to attack. In such cases sometimes customers find their server is sending spam email, and is prone to other malware occurring on the Rackspace Network.
Due to AUP and other obligations, it can become a critical issue for both the uptime, and reputation of your site. In many cases, customers do not necessarily have forensic experience, and will struggle very hard to remove the malware. In some cases, the malware keeps on coming back, or, like in my customers case, you could see lots of extra network traffic still using tcpdump locally on the box.
Enter, netfilter, part of the Linux Kernel, and it is able, if you ask it, to track down where packets are coming from, on a process level. This is really handy if you have an active malware or spam process on your system, since you can find out exactly where it is, before doing more investigation. Such a method, also allows you to trace down any potential false positives, since the packet address is always included, you get a really nice overview.
To give you an idea, I needed to install a kernel with debuginfo, just to do this troubleshooting, however this depends on your distribution.
Updating your Kernel may be necessary to use netfilter debug
$yum history info 18

You could use a similar process using netfilter.ip.local_in, I suspect.
The Script
#! /usr/bin/env stap
# Print a trace of threads sending IP packets (UDP or TCP) to a given
# destination port and/or address. Default is unfiltered.
global the_dport = 0 # override with -G the_dport=53
global the_daddr = "" # override with -G the_daddr=127.0.0.1
probe netfilter.ip.local_out {
if ((the_dport == 0 || the_dport == dport) &&
(the_daddr == "" || the_daddr == daddr))
printf("%s[%d] sent packet to %s:%d\n", execname(), tid(), daddr, dport)
}
Executing the Script
[root@pirax-test-new hacked]# chmod +x dns_probe.sh [root@pirax-test-new hacked]# ./dns_probe.sh Missing separate debuginfos, use: debuginfo-install kernel-3.10.0-514.2.2.el7.x86_64 swapper/3[0] sent packet to 78.136.44.6:0 sshd[25421] sent packet to 134.1.1.1:55336 sshd[25421] sent packet to 134.1.1.1:55336 swapper/3[0] sent packet to 78.136.44.6:0
I was a little bit concerned about the above output, it looks like swapper with pid 3, is doing something it wouldn’t normally do. Upon further inspection though, we find it is just the outgoing cloud monitoring call;

Upgrading PHP 5.3.29 to PHP 7 on Centos 6.8 Using Rackspace IUS Repo
These instructions only apply in specific cases. Specifically CentOS machines, running in the Rackspace Cloud, IUS the Rackspace provided repo, provides several things not usually available within the CentOS repo, without you manually compiling more recent versions. One of them is the latest version of PHP7.0 and PHP7.1.
I wanted to quickly document the process, since it is a relatively simple process, and, can actually be done without any maintenance window, if you know what your doing, with very minimal, (if any) disruption to running sites. an apachectl graceful, actually, should be enough. Since apachectl gracefully restarts apache httpd, the downtime you’ll see will be super minimal. Expect nobody to notice you upgraded to PHP7 if you do this right.
If you do this incorrectly, you will break the PHP installation, and worse, break all of the sites using mod_php. Lets take a look at the steps:
Step 1. Check available PHP modules provided by presently configured REPO

As we can see php7 is there. Great. But what about the php packages they have already? That’s coming up next.

Step 3. Run a mock yum replace

Naturally, if you are satisfied that you do not need php53u-zts, the only php module which is not supported by PHP7, then you can proceed.
If you are wondering what ZTS is, The php-zts package contains a module for use with the Apache HTTP
Server which can operate under a threaded server processing model. (source pbone.net CentOS REPO)
ZTS is not required for MPM prefork, and is generally only used with MPM worker, afaik. So as long as your using prefork apache httpd your fine;
# apachectl -l Compiled in modules: core.c prefork.c http_core.c mod_so.c
In our case prefork is being used, not worker. So I don’t think ZTS being missing is going to affect us. So we can proceed with typing ‘y’.
And’ thats pretty much how you upgrade to php7, it’s really easy with Rackspace IUS.
