I am using haproxy for the first time.I downloaded the latest version 1.4.7 and then unpacked it.then opened the terminal and wrote the command
After which an executable haproxy file was created which I copied to /usr/local/sbin. then i wrote $sudo make install. then I make a configuration file in /etc/haproxy.cfg which is as follows
But it's not working it is various kind of errors intially it was showing "cannot bind to socket" so tried changing the port number but didn't help. I also used command like $sudo sysctl net.ipv4.ip_nonlocal_bind=1 But didn't help.
I 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.
I am working on a load balancing project. The type of routing I am implementing is direct routing (LVS-DIR).
The following is a script that sets up the Linux Virtual Server (LVS) or the load balancer:
On both, the LVS and Real Server 1, the firewalls (iptables) are not running.
A few questions I have are: 1) On the LVS, is apache supposed to be running? 2) If so, what would be the ServerName for apache on the LVS? 3) What would be the ServerName for apache on the real server1, is it the server real IP or the VIP?
When I try to access the web content on real server1 in a browser on the LVS, I get Failed to Connect. A connection to the server cannot be established.
The load balancer has two NICS, eth0 and eth1. The real servers will connect to the load balancer via eth1, and the client will connect via eth0.
I have set up one of my linux box as link load balancer for two ADSL connection. After deployment, I have found out that instead of being fast, it has become slow. What I have observed that my request get out to internet but comes back intermittently. Is this a standard scenario ?
My requirement is to route ssh sessions from a single head node to multiple slave nodes. So what i want is, for a client there is just one point of entry (master/head node) to ssh into, it evaluates the load on the slave nodes connected on to internal network and routes the ssh session, kind of a ssh load balancer. Do you have any idea what open source solution i can apply for my problem?
I have tried using LVS piranha, it works well for http and https load balancing but not for ssh load balancing.
I am about to build a server cluster with mysql-cluster and a couple of apache webservers. I have found lots of tutorials regarding the setup of haproxy, but i have the option to get a pretty affordable barracuda load balancer. Now, i am kinda new at this. But my main questions are.. Can the load balancer also serve for the database? Is it a straightforward configuration?
I have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?
how to install stunnel (patch I think ) with haproxy. I guess I would need clear cut instructions because I will be doing this on a production server and dont wanna make any mistakes.
I have 2 services registered one for HAProxy and one for stunnel. When I type service start haproxy or service start stunnel they start and everything works fine. I ran ntsysv and they are set as autostart, and I have init.d scripts that work. I have checked the runlevel and using chkconfig runlevel 3, 4 and 5 are :on. And I also added service haproxy start and service stunnel start to inittab. But when I restart the computer haproxy and stunnel fail to autostart. I am a fedora novice and I have no idea why this isn't working...
We have 2 HTTP Load balancer with HAproxy and heartbeat. There are 4 nodes in this cluster. It's doing round robin load balancing. The HTTP cluster working fine. We are having problem with our portal because it uses SSO. We need sticky connection support in our HAproxy. Also we need load balancing for HTTPS traffic. Here's our HAproxy conf file.
Will squid or HAproxy work to reverse proxy non-http traffic? I have searched and searched for a reverse proxy solution for non-website traffic. TCP but not http, on ports other than 80, 443, 8080, etc. Basically I just need a TCP forwarder that works with multiple TCP servers, WITHOUT webpage caching features. I do not need or want any webpage caching. Can squid work as a reverse proxy for TCP traffic without http? The other program I came across in searching was HAproxy. Both programs are for http but I am curious if they would work for TCP servers that do not serve webpages.
I have suspicious requests in my haproxy logs from multiple sources to the same target. I could deny them in /etc/hosts.deny, but there are too many to keep track of. Is there a way to deny all requests to a specific target either in haproxy or through iptables?
Here's an example of the request: Apr 12 15:11:37 127.0.0.1 haproxy[28672]: 41.105.42.150:27072 [12/Apr/2011:15:11:37.315] web_servers frontend_farm/######## 3/0/1/1/169 404 1073 - - --NI 3/3/2/1/0 0/0 "GET /images/comment_icon.gif HTTP/1.1"
I've commented out my amazon instance id for security purposes. The request is for comment_icon.gif which does not exist. All requests go to that. The source IPs are from different countries as well. Blocking a certain country won't work either. Basically, if there was a way to send all requests for comment_icon.gif to /dev/null or something it would work.
I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.

The wired internet connection for my notebook works fine after starting up Fedora. Webpages load quickly. But if I close the notebook for as little as 10 minutes, webpages won't load at all, even though NetworkManager still shows that there's an internet connection.
Disconnecting and reconnecting doesn't fix the problem, and neither does logging out and logging back in. Restarting the computer does fix the problem. This problem doesn't occur with Windows 7 on the same machine.
I had actually the same problem in 10.10, but I was patiently hoping that 11.04 will fix it for me. At the moment it's facebook(nothing will load) and lifehacker(mainpage will load,but further on no news will load) First of it loads facebook after fresh install, but when i closed firefox, and reopened it, it won't load. I pinged facebook.com and it's working:S Chrome for instance loaded facebook atm, but didnt load lifehacker news aswell. Altho Windows on same machine will do it perfectly. I would like to use 100% ubuntu, but its not possible if some essential webpages won't load
I'm trying to do a implementation of load-balance with fail-over system using (ip route2 + netfilter), anyway after spent many time on it, I can't do it on my own, I think I'm so close about the solution anyway after check each line 30 times I'm really lost on IT.
I am having a problem getting ISP load balancing working. Currently I can get only one side or the other working. I have been researching and reading Forum threads and other related posts on the subject.. I have read Howto's and lartc.org/howto.
I'm a first time poster and new to openSUSE. I've had a small amount of linux experience and even studied UNIX a few years ago - unfortunately, to paraphrase Homer Simpson, "as something new enters my brain something old has to leave". In this case nearly everything I learned about UNIX
Anyhow, ms problem is this. I've installed 11.2 with KDE desktop. Using either Firefox or Konqueror browsers, I am finding it impossible to display any webpages, other than Google. All google websites, such as gmail, calendar and searches work perfectly. Unfortunately, I can't directly enter a url into the address bar nor can I link from a google search.
I've hunted high and low for a solution but have failed to find one.
I have an Airlink101 AWLL3026 and the zd1211rw driver. When I insert the USB card, it is recognized but syslog indicates that the firmware wasn't where is was expected.I am running an updated Linux Mint system (based off of Ubuntu): Linux hoverfly 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux Plugging in the USB Wifi adapter results in the following on syslog:

When i open one of the web browsers i use and try to load a web site it's taking to long to respond and sometimes it doesnt load the website at all. I have tried with firefox,epiphany,opera with all the same results. I am sure that this is not a problem with my internet connection because i don't have these problems with windows.Also the network manager connection settings are correct
I also tried choosing the old kernel(2.6.32.24) to boot from but no success.The problem is the same as if i am using the 2.6.32.25 kernel. The strange thing is that i can download packages from synaptic with full speed. Last think.I have recently downloaded the recommended updates from the update manager but i don't remember what are the things that where updated.
I had Fedora 7 and Windows Vista dual booting on my computer. I just installed Fedora 10. When the live CD asked me where to install it, I chose "Remove all Linux Partitions and create default layout" The installation went perfectly, but now when reboot my computer, it boots directly into Fedora; GRUB does not load to ask me which OS I want to load. I know I did not overwrite Vista because I can still view my Vista files through Fedora. Here is my grub.conf file:
[Code]...
What do I need to do to make GRUB load again upon booting?
I have found that APACHE or 'httpd' is installed in my machine. But the problem is I can start or stop the httpd but whenever I load the url http://localhost in Mozilla it shows a page load error.I have done this ,
$ /etc/init.d/httpd start then this $ /etc/init.d/httpd graceful
I have 3 machine each one is running ftp daemon(example), and have an application daemon which is monitoring load and can communicate with remaining servers. now for every new connection I can check load of each server and I want to redirect that socket connect request to least loaded server. that load balancer daemon should be able to do this at runtime without breaking any existing communication. This should work seamlessly with any application. How I can achieve it using any combination of Advance routing, VLAN, iptables LINUX.
I can't seem to fire up any web pages but I can do everything else on my ubuntu box. This seems to have started within the past day or so. My /etc/reslov.conf file looks solid.Again, I can ssh, vnc and ping to the outside but just can't load any web pages.
