[Configure applications] deploying (32-bit) V2 system environment in LVS + keepalived Server Load balancer CentOS5.6 environment: CentOS5.632-bit (minimum installation) if you try to compile in 64-Bit mode, an error will occur, the system prompts that some kernel library files cannot be found. The file name contains 64 characters, so it is difficult to modify the original installation package one by one bec
Web server.(2) The Load Balancer (control side) failure can cause the entire database system to be paralyzed.Third, database split (distributed)By a certain condition, the data stored in the same database is distributed to multiple databases, distributed storage, routing rules to access a specific database, so that each access is not a single server, but the n server, which can reduce the

Abstract: rhel5.8, mysql, keepalived, and haproxy are used to build a cluster with high availability and load balancing. mysql
: This article describes how to use Nginx server load balancer to build a high-performance. NETweb application 2. if you are interested in PHP tutorials, refer to it. In this article, we use Nginx server load balancer to build high performance. in NETweb Application 1, we have a preliminary understanding of Nginx. next
there is a machine down, it is only one of the db n one of the data can not access it, which we can accept, at least more than before the segmentation of the situation is much better, not the entire DB can not access. In general applications, such machine failure caused by the data is not accessible is acceptable, assuming our system is a high-concurrency e-commerce site? The economic losses caused by single-node machine outages are very serious. In other words, there is still a problem with ou
Server Load balancer distributes the load evenly to each node in the cluster to improve overall performance. Oracle RAC provides two methods to achieve load balancing. The following is a detailed introduction. For more information, see

Network Server Load balancer allocates incoming network communication between one or more virtual IP addresses (cluster IP addresses) assigned to the Network Server Load balancer cluster, resulting in changeable performance. Then, the host in the cluster simultaneously r

is not a test. Of course, there is always a solution to the problem. We introduce the concept of clustering , which I call group, that is, each node of the library we introduce multiple machines, each machine holds the same data, in general, many of these machines load, when there is a downtime situation, The load balancer allocates the
group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer distributes the load to the machine that is down when there is an outage. This solves the problem of fault tolerance.As shown, t

In this example, I will configure a cloud service Travelweb, which has two VMs, which together provide HTTP services1. Create the first VM TRAVELWEB01, specify the cloud service name as Travelweb when you create it, add an HTTP endpoint2. Create a second VM TRAVELWEB02, using the existing cloud service TravelwebAt this point, both VMs are under the same cloud service and TRAVELWEB02 cannot use public ports 80 and 223. Modify the TRAVELWEB01 endpoint to create a
Before a project needs to configure load balancing on Apache, because of the variety of things, time is tight, there is no time to get.Today, the time to test a piece, at least can be a proxy.You will now configure how the reverse proxy and load balancer are described separately.1. Reverse ProxySteps:(1) Open the reverse proxy module in Apache configuration file
