Bian Bi is different from his multi-data industry. In his eyes, it is not the same kind of life that only occurs once and there is no clear cause.Blame for the crash event. Researchers from around the world over the past decade have learned that criti

In Dr mode, both the LVS host and the actual server have a NIC connected to the same physical network segment. IP Address Allocation VIP: 10.10.3.170 Rip1: 10.10.3.140 Rip2: 10.10.3.141 1. Install the required dependency package yum install -y wget make kernel-devel gcc gcc-c++ libnl* libpopt* popt-static 2. Create a soft link to prevent the system kernel from being found during later compilation and installation of ipvsadm ln -s /usr/src/kernels/2.6.

Dr images are prone to S-shape, pillow, and local distortion, which interferes with the doctor's image judgment. In addition, in the three-dimensional reconstruction of medical images, uncorrected images can be reconstructed, which may cause interference such as ghosting. Therefore, distortion correction is a problem that must be addressed after Dr images are processed. Figure 1 original target image Fr

When building the Dr mode of The LVS cluster, we need to modify the arp_ignore and arp_announce parameters of the Real Server. The main purpose of modifying these two parameters is to ensure that the request is sent to the VIP on ctor when the client sends a request to the VIP, instead of the VIP on the Real Server. The following describes the meanings of different values of these two parameters. Arp_ignore Parameters: When the target address of t

Configure the LVS Dr cluster on centosI. Environment Three cluster servers: centos 5.5x86 One client operating system: Windows 2008x64Ii.

About LVs DR (Direct Root) mode DR mode requires Director and realserver on the same network segment, the user through the VIP to access our services, Director received the user's request, will be the request of the target Mac to one of the realserver above, So realserver receive the request processing directly after the content returned to the user, no longer walk directorserver.

Ldirectord Introduction: In order to failover the LVS load balancing resources from the main director to the Standby director and automatically remove the nodes from the cluster, we need to use the Ldirectord program, which automatically builds the Ipvs table at startup, It then monitors the health of the cluster nodes and automatically removes them from the Ipvs table when it discovers the failed node. Ldirectord monitoring cluster (real server): The Ldirectord daemon enables monitoring of rea

I read "Work with linux completely" written by Dr. Wang Yin of Tsinghua University-Linux general technology-Linux technology and application information. The following is a detailed description. I think this life is too arrogant and extreme. Any system has merits. Do you have to drop MS to nothing? In the evening, I tried msn space, and I only wanted to find someone to get rid of it. This reminds me of Wang Yin's words: "What Microsoft can do but what
