View 1 RepliesI 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?

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 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 ?

View 1 Replies View RelatedI 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.

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.
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 installed all of the software I wanted.I now want to clone the installation to 6 other workstations that are 100% identical to the first.I used clonezilla to create the image, but all of the new workstations will not boot. This is due to the fact of the fstab being 100% cloned and other boot volume problems.Does anyone know of a good, easy way to clone opensuse 11.2 that will work?

Now that Ubuntu 10.10 supports all my hardware out of the box,I'm planning on using that, but I'm looking for a good replacement for Windows Journal. I don't need compatibility with Windows, but I do need to be able to save and load the notes. Handwriting recognition isn't needed or really wanted, I just use it to draw graphs, formulas, and musical notation for various classes.I love Tomboy, if there's a version that supports touch, I'd love it, but really any app that allows me to draw sometimes and type sometimes and easily switch between the two.

I have a 10.04 32-bit virtual ubuntu server. I am trying to figure out how to setup load balancing. Here is how I planned out to do it, I need direction for what software I should use.
--Internet(1.2.3.4)
--Router
---Load Balancing Server (192.168.1.30), port 80, public as in port forwarded Load balancer sends traffic to either web server
---Web Server 1 (192.168.1.100)
---Web Server 2 (192.168.1.101)
I heard I should use rsync to keep the files concurrent, at this point rsync is the least of my worries. I need to know what load balancer I should use I have tried and failed with crossroads(xr), and balance. I can't seem to find a modern tutorial for either system. I looked at linux virtual server but that is like 5 years ahead of my current knowledge.
I'm a newbie on Ubuntu, I have a problem with squid proxy. I'd like to configure a system, include:
- a server is named ProxyServer that is installed Squid proxy.
- three servers, are named FTPServer01, FTPServer02, FTPServer03. each server is installed vsftpd.
- Clients are installed Filezilla to up/download resource.
All servers are managed by IP address. When a client request a resource, client connect to ProxyServer, this ProxyServer will switch to one of Ftp servers. I do not know how to configure the squid's config file to setup them.
I am trying to setup a ventrilo server. I want it to load the server automatically on system boot so it is running at all times. I have downloaded the server files and can manually start it, but I do not know where/how to make it start automatically.
View 1 Replies View Relatedhow to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?
I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.
I just upgraded to F15 and it went well. But at the next and each subsequent cold boot the BIOS reports "Your system last boot fail or post interrupted Please enter setup to load default and reboot". The board is an asus P5N-D. I press F1 to blow past the error and all is well until the next cold boot. Restarts are fine, no errors at all.

I wanna get into the world of stereoscopic 3D and I was wondering are there any easy and straightforward solutions. Do I need specific hardware to view the results of my work? I heard that there are screens with which you don't need goggles but that there are problems with that too..
I might start doing something like 3 dimensional charts for example that I could actually see in 3D. I would definitely stay away from modeling characters like in 3D shooters.
I was wondering if there's an easy way to upgrade VIM 6.3 to 7.2? I have CentOS 4.7 and wanted to upgrade my current vim to 7.2 to support other functions that we do. Unfortunately I am running into some conflicts/ dependency errors (i.e. glibc etc) and I am not so sure on how to resolve.
View 2 Replies View RelatedI currently have a VPS(virtual private server) that runs Slackware 12. The image was made way back in 2007, and obviously it hasn't been updated.The version is VERY minimal, it doesn't even have all the packages from A, but I can get any I want and install as I wish.Is there an easy way to update 12 to 12.2? Going to 13 is probably out of the question without a clean install over a network and doing it remotely, which is probably beyond my capabilities.I can't mess with the kernel unfortunately, but I can install practically any packages.
