Server :: How To Achieve High Availability Website?
Apr 7, 2011I have 2 web servers running apache hosted at 2 data centres on 2 different IP ranges.The 2 servers are an exact clone of each other hosting www.example.com.What I am trying to achieve automatic failover. Say my first data centre gets wiped out, how would customers reach my website on my second server in the second data centre by still typing www.example.com?The aim is for the customer not to notice any difference.

Aug 19, 2015I work for a data center where we use a whole lot of VMware's "Fault Tolerant" Solution. As a personal project, I want to piece together an alternative solution out of open source software.
Here's my punchlist:
*Configure Debian (or build from scratch) to be as slimmed down as possible so that I may call it "Just Enough OS" or "baremetal"
*Install and configure Xen with XenMotion
*Prove that both the physical and virtual fail-overs work as intended
*Prove the automatic repair of failed virtual machines.

View 3 Replies View RelatedFedora Servers :: Squid 3.1.1 Proxy Server Will Not FTP
May 11, 2010I have 4 servers running squid/3.1.1 proxy server. Since the latest version I can no longer FTP. I have posted this problem in multiple places but have received almost no response. I've found several other post to this problem throughout the Internet which have also gone unanswered. So, once again, I thought I'd give it a try. As I said "I have 4 servers running the newest version of Squid". When I try to access an ftp, any ftp, I receive an error (check attached image). This was never a problem until just recently. Squid should work perfectly find with ftp, it is not a strictly http proxy.
I turned my firewall off just to make sure, still had the same issue. If I jump directly on the server itself with no proxy settings set in the browser it will work fine. As soon as I set the browser setting to access the Squid software I get the same error. I've included my squid config (which is unchanged from the default settings), maybe somebody better versed than myself can point out an obvious flaw. Everything else seem to work just fine, it's only FTP that's a problem.
Fedora Servers :: Reverse The Proxy With Squid?
Mar 14, 2011I have a reverse proxy set up with squid. I'm going to try and explain what it's doing and I apologize for it being confusing, I'll do the best I can to describe my problem. First, it's for our phone system. We run a ShoreTel Voip system. The owner has decided he wants me to setup MCM (Mobile Call Manager), which from what I can see is an under developed, and almost impossible to get help with Shoretel software. But he's convinced he needs it for his Iphone. It's supposed to, in a nutshell, turn his Iphone into his work phone with all the advantages and doodads that come with it. Apparently, "they have an app for that". On the server side, I need to setup a reverse proxy back into the network on our phone server. Simple enough, I did this with squid. I used the following lines:
Code:
http_port 80 accel defaultsite=172.17.137.7
cache_peer http://172.17.137.7 parent 80 0 no-query originserver name=myAccel
acl our_sites dstdomain http://172.17.137.7
[code]....
Code:
always_direct allow all It most definitely is allowing traffic back to the phone server, the problem is, it hands out my internal server address to the outside client. So for instance, if I connect to the outside routable address with my phone, it will immediately change the url to http://172.17.137.7 which is the inside nat address of my phone server. Which of course doesn't work, since I couldn't browse to that address from the outside. It does however work from the inside of the network, obviously because 172.17.137.7 is accessible from the inside.

View 1 Replies View RelatedUbuntu Servers :: Squid Proxy Very Slow For Web In Default Config?
Jan 10, 2010I just set up squid for the first time. I have zero experience with proxy servers. I used this guide:[URL](I also looked at a few other guides such as this one:ttp://ubuntuforums.org/showthread.php?t=320733. However, I wanted to most barebones config to start with and the link I used was the simplest.)So now that I have it set up, I'm testing it with FoxyProxy. It is not working well. I went to speedtest.net. The download and ping tests were just as fast as without the proxy, but the upload test fails completely.Furthermore, many web pages load very slowly or not at all. So performance is very mixed, but mostly poor.

Oct 15, 2010I am trying to setup a High-Availability HTTP Load Balancer With HAProxy & Heartbeat using the below links.
I have all RHEL 5.4 servers hosted on VMWare.
[url]
[url]
This is the scenario, as given in the links as wells as my setup.
Load Balancer 1
Load Balancer 2
Web Server 1
Web Server 2
I have followed all the steps mentioned in the links religiously except the 2.2 here, in which it is asking to configure the vhosts. I could not really understand , what is to be placed in /etc/httpd/conf.d/vhosts.conf file and in which Web Server.
Due to this step only, I think I am failing in Failover test given in Point 4.1 here. I am able to open the webpage by [url] which gives the content of Web Server 1 (http1.example.com). But, when I try to shutdown the http service (to check failover), it does not shows the contents of Web Server 2 (http2.example.com)
Although, I am able to succeed in Failover Test 4.2, in which shared IP 192.168.0.120 switches when I try to start/stop the any of the Load Balancers.
Fedora Servers :: Configure Evolution-mail Clients Through SQUID Proxy?
Jul 27, 2011I have configured router(192.168.1.2) to serve only one machine with IP - '192.168.1.6' and set up SQUID proxy on '192.168.1.6'. I have defined some rules(ACL) regarding connections to internet on SQUID proxy.
I changed the Gateway of rest of machine (192.168.1.60 - 192.168.1.69) from '192.168.1.2' to '192.168.1.6'.
The policies which I defined in SQUID is working properly but 'Linux Evolution mail' client is not fetching mails.
Is I have to do any other settings on 'Linux System' or 'Evolution mail client'.

Aug 19, 2010I have a firewall / proxy that has an extremely high load, but I can't figure out what's using it. No real cpu usage, the disks are sleeping except for a little log activity, it's on gigabit ethernet and not close to maxing out... Command link stuff runs fast, nothing seems slow, yet the load is sky-high. IME this kind of load is associated with a lot of disk I/O, but that's not the case here.
