Varnish HTTP accellerator and Cpanel

[k-planethost]

i had try this appears to work
cd /usr/local/src
wget http://stderr.net/apache/rpaf/downlo...paf-0.6.tar.gz
tar -xzf mod_rpaf-0.6.tar.gz
cd mod_rpaf-*
apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c

2. Once installed, we need to load the module into Apache configuration. Since cPanel already has Include Editor for Apache, we will use that functions. Login to WHM > Service Configuration > Apache Configuration > Include Editor > Pre Main Include > All Versions and paste following text:

LoadModule rpaf_module modules/mod_rpaf-2.0.so
RPAFenable On
RPAFproxy_ips 127.0.0.1 123.124.125.88 # replace the value with your server IP
RPAFsethostname On
RPAFheader X-Real-IP

varnish can be installed on value vps with 1g memory ?
with cashe size about 128M to 256M

Does the Varnish plugin decrease the effectiveness of mod_security (partially or completely)?

[k-planethost]

no mod security rools are doing their job as before

I've been running the Unixy plugin for about three days now. I've noticed the following changes in Munin readings:

• Total threads increased 300%.
• mySQL threads increased 100%.
• Firewall throughput increased 200%.
• Load average is slightly higher, whereas I would have expected it to drop a bit.

Are these results normal? If not, how can I resolve these items?

Thanks,

Mark

Hello fellows

Here is my 2 cents on these plugin:

1-. It works well, and resolve all the complexity involved in varnish integration with cpanel, that includes the management of configuration changes for subdomains, addon domains and so on.

2-. You have to clearly understand the impact of any acceleration server or cache proxy on the web server metrics, that´s something that should be that way, i´m talking about some posts that pretend to make that metric change looks like a fault of the plug-in. the plugin resolve the complexity of varnish integration in a cpanel environment, but it can´t change the law of physics (oh yeah i understand the meaning of that, joe was talking about how a cache or proxy can alter many of the metrics, because is offloading in some areas and making more pressure in others. The effect of varnish can be different depending in how your applications are wrote and what are they doing.)

3-. The plug-in delivers what is offered, you have varnish up and running in seconds, ready to rock&roll, no maintenance required, you just have to decide what to put behind the cache and what to expose directly and how much memory you like to use for the cache. I be-leave these product is a must have for anyone running very active wordpress or joomla (any cms) sites, blogs, portals.

I make a great product for hosting active wordpress sites, varnish (unixy plugin) cpanel server for php in front, one server for mysql and another for static files. 3 machines for a shared enviroment for more active sites, sweet!. It rocks and i can´t colapse the server even making artificial traffic from several nodes. (3 dell poweredge 2950´s with 8 cores, 3 arrays with 7x300gb 15k drives, it`s running over 200.000 visitors a day, load average is under 1.) These is just perfect for a premium shared hosting offer and for all the people with active wordpress blogs and portals. I have these setup running with mod_security with atomic rules on it. Works like a charm.

I think joe do a good job on these, I don´t have to waste time installing varnish any more. I suggest to give these a try.

Best Regards from Chile!

• All software products have defects including this plugin. The installation "leftovers" are harmless but will be fixed in 1.4.5rc2
  

after ONE year, this "leftovers" are still not fixed

could you tell how to completely and properly remove whole cpanel varnish plugin?

after we uninstall "cpanel varnish plugin" from WHM-> Cpanel Varnish->remove cpanel varnish, Service Status still show it is there and up

we also try to run python uninstallvarnish from SSH, same...

is this plugin still being developed? helpdesk support is basically dead

[luigidelgado]

Interesting Unixy has the plugin abandoned... I was about to order it. I need a Varnish installation and tuning ASAP...

Can you provide a ticket so I can review your request / bug report? Plugin support is on best effort unless you choose to select one of our SLA based add-ons. Email sales for the details.

Interesting you're making a baseless comment. Your application for the trial was denied because you opened two accounts in the system and had already requested a trial, which was granted.

Wow!! Super fast answer in the public forum, never by customer service email but thanks for your explanation.
Well I am not aware to have two accounts (why dont you responded this by email asking if I had opened an account a year or X time before ago that may no longer have access to?) I always thought trials were free to try and see if you like it and see if it works for you... maybe its buggy... maybe it doesnt work... who knows... Im a cutomer right?
I dont see the probem with asking for a new trial A YEAR LATER to see if the plug in works for me in another server, you could have ASKED. But never ansered mails. Sorry. Plug in is not abbandoned. Customers are abandoned.

BTW the last trials I could never make them work. Thanks for your kind explanation.

Does anyone know if there is a way to upgrade Varnish to the latest version without messing up the plugin?

The latest plugin was released with Varnish 3.0.2 right around the time that Varnish 3.0.3 came out. I would like to upgrade varnish but don't want to break anything.

My initial support responses from Unixy were similarly paranoid when I tried the plug-in some time ago. After that, the support was very good.

Like you, I tried it some time ago and was not ecstatic about it at that time, so I did not continue with a paid license - however, I would potentially be interested in trialing it again at some future point in time as our needs continue to evolve.

Just my two cents, I am not sure how large the Unixy company is, but sometimes support seems to be really fast and sometimes not. I understand how it is in this economy to be a small business trying to keep up with demand, some days I am right on top of replying to clients sometimes I'm a day or two behind. All in all, I love the plugin, I have setup varnish without it before more than once, and it is easy to setup, but not so easy to administer. This plugin takes the work out of it, and is well worth the time and effort. If you have a need for varnish cache and you use WHM, then this is the way to go, hands down.

FYI, we can't offer free support for the Varnish plugin to subscribers. This is an unsustainable business model. What we do is offer support to subscribers for extra fee in the form of an add-on. So we have an installation add-on, a request-based support add-on, and custom VCL modification add-on. Subscribers that need help outside of the service level agreements are serviced on best effort.

However, we provide free Varnish / VCL support to our VPS, dedicated server, and cluster clients. We don't charge extra for installation, support, maintenance, and/or VCL modifications. We also don't charge for the plugin. Before we released this plugin as well our Varnish load balancer solution we were a fully managed server provider and we still are. That's always been our core competency.
