Hi there, I'm currently involved in a Project that requires high-avaiability and load-balancing for web servers and database servers. In order to have a load-balancing webserver, I use LVS and I use dns round robin. Basically I have the hostname with 2 distinct IP, so I have some load-balancing right from the start, using DNS. Then I have 2 machines (low-end) , that run LVS, and this machines are high-avaiable , using heart-beat. As to storage , I have the machines using an iscsi share , shared by a machine running with a raid 1+0. Regarding the database servers, i use Oracle so perhaps this is off-topic for you :) Best wishes, Bruno Sousa -----Mensagem original----- De: centos-bounces at centos.org [mailto:centos-bounces at centos.org] Em nome de Mace Eliason Enviada: terça-feira, 23 de Maio de 2006 16:52 Para: CentOS mailing list Assunto: [CentOS] Load Balancing Hi, We are starting a new project, and are trying to decide the best way to proceed. We want to setup a LAMP configuration using Centos, something we have been doing in the past with great success. The question is load balancing. We antisipate the potential for the system to receive 500,000 requests/ day with in the next year. We want to plan for that extra load now as we start the project. What would you suggest for setups for multiple servers for redundancy and load balancing? I have setup MySQL replication and that works fine but what about the rest of the system. I know it is quite simple to setup with windows 2003 server. Would a cluster be the way to go? Ideally we would like 2-? severs setup that are all identical and sharing the load as need be, and if one fails users would notice nothing. I have also thought of just looking for a hosting company that offers load balancing servers and not worry about it but we like to have control. Thanks for any suggestions Mace _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos -- No virus found in this incoming message.
