I used both pound and nginx as load balancers. With pound I had issues with SSL websites so I moved to nginx. With nginx I have the problem that it does not load balance equally between the backend servers.
I remember hearing something about another load balancing web server but I forgot its name.
Does anyone know other alternatives to nginx/pound?
I have two machines fairly decent which I wish to cluster and run a vm (preferred choice virtualbox) on it, if possible with load balance.

We have a server that needs to be hi availablility.
The problem is, sometimes our internet winks out for a few minutes.
We decided that we wanted to get two seperate lines to our server, and so they would be two different ip addresses.
What out there would allow us to serve apache on www.mywebsite.com on more than one ip, and, if we can, do load balancing?
I have two Red Hat entreprise Linux 5 servers running the same applications, my goal is to load balance the incoming traffic between these two servers without adding an additional hardware as load balancer, the incoming traffic is basically Web traffic and on the servers, Apache and PHP are running. Red Hat solutions that I found are:
1- LVS
2- Piranha
3- Red Hat cluster suite.
Can LVS run on one of the real servers (or both servers, for redundancy issues) and load balance the traffic between its server and the other one? If yes, will LVS has a big impact on the CPU/memory usage? How can I estimate this usage if I know how much traffic is coming and the HW specs?
Can I install Red Hat cluster suite on these two servers, and configure it in a way that the virtual IP is on different server for different request (taking in consideration that the same session will be always served by the same server)?Finally, is there any other/better solution that can fit my requirements to load balance the traffic without additional hardware?
My problem is that I would like to load balance or aggregate 2 separate Internet connections on my laptop. Currently a hard line ISP is not available so I'm using an Sierra Wireless 885 USB air card. Thing is the card is quite slow. I also can tether an iPhone to the laptop. The ideal solution would be to have both connections being utilized to help speed up the overall experience, even if it is only a modest gain in speed.
as I do not know much about iptables and basic TCP/IP routing, I'm finding it difficult to implement those solutions. If someone can point me in the right direction ( a slightly dumb down how:to? or better explained? )
BTW, both phone and aircard get dynamic IP's. Running Ubuntu 10.4
I came across this while trying to find a solution for my load-balancing clustering issue in another thread. Since I perceive this as something on its own, I decided to post a new thread. I came across this site to setup a two-server cluster using Conga - Luci and Ricci.
From my understanding, this is what was done:-
1. Both servers have luci running using a shared storage via GFS to provide a failover
2. Both (and same) servers have ricci agent running for the clustering
I'm aware that Conga clustering aim to achieve High-Availability.
1. Can it also achieve Load-Balancing?
2. If yes, would the guide from the link above be sufficient or would they be additional setup/pre-req to be done? Since I'm new to this area and there was no mention of load-balancing, I'm still wondering if this is what I need to incorporate.
I seem to be having a strange problem configuring Piranha to load balance (Direct route) 2 ports across 2 w2k3 servers in a test environment. What is strange is that 1 of the ports are working fine but the other port doesn't work. I've read many how-to and after many frustrating hours I disabled the firewall, iptables and arptables services and one of the ports are load balanced across the 2 real servers. Here's the environment.
[Code]....
I can telnet from the client to the realserves on both ports and it's works. When I telnet to the VIP only one port gets through and the other gives me "could not open connection to host port 32777 : connect failed. The configuration in Piranha for one port is the same as the other. I can't help but think that some other configuration for port 32777 was missed.
I want to install GTK+. I see there are also numerous dependencies, which i've been slowly tackling, and the Cairo package has been particularly difficult. It claims the following upon ./configure --prefix=/usr configure: WARNING: Could not find libpng in the pkg-config search path checking whether cairo's PNG backend could be enabled... no configure: error: requested PNG backend could not be enabled I've done some searching and found that libpng.pc is in my /usr/lib/pkgconfig/ directory and that the following commands don't do the trick:

I had a dedicated HTPC box running Mythbuntu 11.04 (MythTV 0.24.1, I believe) that was both a master backend and frontend. I was also running a separate box (server 10.04) as a file server, print server, etc. Very recently I decided to try to migrate the backend duties and database from the HTPC box to the server so that I only need to have one machine running 24/7. So, on the server, I installed mythtv-backend-master from the repository, which for 10.04 is version 0.23.0+fixes. You might have seen this one coming... when I try to import the database from the Mythbuntu box into the server's MythTV installation, I get an error message saying the database schema (1264) is newer than expected (1254).
So, I'm wondering about my options at this point. Is it reasonable to install the same version of MythTV on the server? What would be the best way of going about that?
Is there a way to easily revert the database schema to the earlier version that's required?
Will I just need to start over with a new database? (Hopefully not this one.)
Other options I haven't thought of?

I am using Fedora Core 10 and have all of the latest updates installed. When I try to connect from a Windows machine, I am prompted for a username and password. I enter the username and password of the account I created in Fedora Directory Server in OU=People. The credentials are rejected. At the same time in the log file I see this:
[2009/02/24 16:50:16, 3] auth/auth_sam.c:check_sam_security(282)
check_sam_security: Couldn't find user 'Administrator' in passdb.

check_ntlm_password: Authentication for user [Administrator] -> [Administrator] FAILED with error NT_STATUS_NO_SUCH_USER
Administrator is the user I created in Fedora Directory Server. If I perform an ldapsearch it will find the user as uid: Administrator so I know it is able to be looked up in FDS. But I'm guessing that's not the problem.

I am seeing an issue on a few servers where it doesn't appear all NICs in the 802.3ad lag are all operating at the same level. A few of the servers have two bonds each with two NICs in each bond.I have two NFS servers that each has 1 bond with 3 NICs.All are RHEL5 x64 2.6.18.I think the reason why I see one interface dominating RX and another dominating TX is due to the xmit_hash_policy but there are three hosts that use this particular server for network traffic.That's 3 different physical mac addresses.The layer2 algorithm should be fine in that situation I would think.Would I just be better off with balance-rr?

I have an Ubuntu Server 8.04 that is operating fairly high CPU loads - Samba appears the culprit. I have 5 main shares with 17 users. Other packages include Apache (2 Wordpress sites for intranet only), YaCy (minimal indexing 10 pages/minute), and a MySQL business database with no more than 10 concurrent users. This only started in the last 2 weeks - updates are not the culprit.

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.
as soon as mysqld starts it goes 100% cpu. I can stop it, there is no mysql_safe running, and I ran mysqlcheck -A -a -c -o -g --auto-repair -u root -p all is ok, syslog shows nothing important but I can't login to any account with mysql client it just sits there, using php it times out. I don't know how to fix the urgent situation...
Looks like it has been started after a release update to 9.10 or 10.4 (i did it in a row) I don't know if this bug is related [URL]
