Source compile php 4.4.2 for Plesk

Work — Mon, 19 May 2008 12:14:43 +0000

I had to figure out how to compile php on a plesk machine and actually get it to work so I took the time to document everything. This guide *should* work, I know it worked on 2 seperate machines. Aside from that do it at your own risk I am not so fond of plesk because it does have so many issues with upgrade. If you have any trouble or dep issues please post thme here so I can work the fixes into the guide.

Ensim X python upgrade problems

Work — Mon, 19 May 2008 12:11:18 +0000

Ensim python upgrade problems:

If you end upgrading python when doing an overall system update you may start to obtain internal server errors on every page within the ensim control panel. To fix this you need to recompile the templates and restart ensim:

cd /usr/lib/ensim/frontend/kidpages/
/usr/bin/kidc -f *
service epld restart

Install yum on RHEL4

Work — Mon, 19 May 2008 12:09:55 +0000

So why do you want to install yum on a rhel box if you already have up2date for RHEL4? Well there are a number of reasons, the main one and the reason I wrote this is that I was installing openvz and it needed yum installed. Trying to just use the yum rpm or source compiling was getting all sorts of python errors. I decided to just grab the centos 4 rpms. Note this is not going to be used for updating, up2date still is used for that.

*NOTE* There was some confusion below, this guide is only to be used on a RHEL4 server - it will break RHEL3.

Just copy/paste the commands

Install openvz

Work — Mon, 19 May 2008 12:09:01 +0000

This is a rather short and simple mostly copy/paste guide on how to install openvz from http://www.openvz.org . I have been working with this product for only a short time but I have found it to be very nice. Since it is based off the same technology that Virtuozzo uses it should be just as stable. The only real downside is that it does not have a fancy gui, I for one can deal with that for a testing enviroment! It also works fine for a production enviroment if you want to host VPS from it. Future guides will cover the actual configuration, this is simply installing it and NOT setting up any VPS. The openvz has a lot of documentation on their website which can also be useful. I am only installing the centos 4 minimal and regular because that is all I would believe most people would want, the website has some more. Hint Hint! Don’t use fedora core!! Also they only have the templates for yum for Centos 4 so using the centos 3 image is hard. They also have images for fedora core with the yum templates if you want to get them. In time I may try to release an image wih cPanel already installed.

Adding a VPS in OpenVZ

Work — Mon, 19 May 2008 12:07:40 +0000

This is another really basic guide that is aimed at getting a very basic VPS online. It is the companion guide to my guide on installing openvz. The below shows the downside to useing openvz instead of paying thousands for a real Virtuozo license. If you can deal with doing a little by shell you can save a lot of cash. This is also an open source project so if you wanted to help contribute you could. I do not go into all of the detauls to configuring it but by the end of the guide you will have a vps with just ssh running.

First off I want to give the link to the official users guide, it is really good and was used extensively in creating a lot of my VPS information.
http://download.openvz.org/doc/OpenVZ-Users-Guide.pdf

cd /etc/sysconfig/vz-scripts
cp ve-vps.basic.conf-sample vps.basic.conf
cp ve-vps.light.conf-sample vps.light.conf

Remove OpenVZ limits

Work — Mon, 19 May 2008 12:06:46 +0000

Below are a quick set of commands which may be useful to those needing to quickly remove some of the more important limits on a VPS. I have found them extremely valuable when deploying OpenVZ in a load balanced or otherwise very busy environment. Note the –save will save them in the configuration file for when you restart it. If you do not supply the argument then when the VPS is restarted the settings will be lost.

Here are some of the links to the latest OpenVZ install files as well as a quick run-down of getting the first VPS up. I got this list when I did a new VPS a few days ago.

Foundry Server Iron Server Load Balancer (SLB)

Work — Mon, 19 May 2008 12:03:47 +0000

I have recently had the pleasure of working with a few of the server irons that ev1 deploys as load balancers within the private racks and in the process of setting them up noticed the lack of easy to read documentation. The foundry website is full of great information but it takes a lot of reading and most of it is targeted at the telnet prompt and not the web interface. I have written this guide targeted at doing an initial setup of the slb as well as some more the more advanced configuration that clients may need. If you have purchased a load balancer inside of a private rack you will be dealing with the same hardware that this guide is targeted towards.
