Compare the speed of the following two scripts: Windows 7 uses localhost to connect to local MySQL at a very slow speed. Windows 7 uses 127.0.0.1 to connect to local MySQL, and the speed is normal. The My.ini is configured in bind-address=127.0.0.1 Connect local mysql with localhost: slow speed Analy
It is necessary to note that the SQL Server failover cluster (SQL Server Failover Cluster) We build is an availability cluster, not a load-balanced cluster, which is designed to ensure continuity and availability of services, not to improve service performance. SQL Server always lacks its own products in a load-balance
Most enterprises in the early IT infrastructure will consider a mix of infrastructure services and domain control roles such as DHCP deployment. This will not only save costs but also simplify management. But as the size of the enterprise expands and the IT infrastructure becomes more and more sophisticated, the mix of deployments can be limited in terms of rights management and usability. Separating the role server is definitely the best choice. Le
, ensure that the update of the operating system of the node is consistent, the newly installed system is either updated to the latest, or temporarily not updated.3, configure the Management Network and heartbeat network in each node, although an available network can build clusters, but best practice is still separate.4. Configure the shared storage disk in each

Failover cluster (WSFC)The SQL Server failover cluster is WSFC-based, so we need to set up a WSFC in two nodes beforehand, where WSFC is just a container, where multiple roles can be placed for failover of those roles. In order to build a WSFC, in addition to the need for a domain environment, but also in the node, storage, network and other aspects to prepare.Cluster1, add failover clustering
Due to the recent long hours of overtime, prepared documents are not timely issued, but also hope forgive me! Recently I will personally before the server, Dell workstations and other devices, the new into hyperspace oxygen workstation for daily testing, after installing the Windows Server 2012R2 operating system found whether I use a USB external wireless card o
Windows cluster requires that all versions of Windows in the same cluster be the same, which is a problem when we want to upgrade Windows (for example, from Windows 2008 R2 to Windows 2012
Demand:Remotely installs Vcredist 2008, 2010, 2012, and 20,134 versions on Windows Server R2.First in the official documents of the ansible to find out if there is a suitable module directly can be used.The first thing to find is the Win_package module: http://docs.ansible.com/ansible/win_package_module.html , and see
will only register the cluster's MAC address. In this way, when the router sends packets destined for the cluster Mac to the switch, the switch will only be forwarded to the hub via this port, not to the other ports, and the hub to all servers. As for the problem of inability to communicate between two nodes after multicast, it is possible after Windows Server 2008. However, it is recommended that you use

With regard to the virtualized network of Windows Server, the previous configuration changes that occurred at the operating system level were described. Some of these configurations are implemented through widgets provided by Windows Server, such as the configuration of NIC
Recently changed a new server, because the memory is 8G, so changed Windows Server 2008 R2 This system, although a little strange, but familiar with the feeling performance is very good, but after configuring the PHP environment but found the problem, access to HTML fast, an
shown, on the physical host's operating system level, the merged NIC Group behaves as a network card and is connected to one another. The functionality of the NIC group is actually provided by Windows R2, and SCVMM can make full calls to all the resources and features of Windows R
Virtualization can be relatively familiar with computational abstractions, perhaps with the experience of using a single machine such as Virtual PC or virtual box. The first impression of using these virtualization software is that our CPUs can run multiple sets of different operating systems at the same time, and that the application runs in parallel. The abstraction of computation allows the operating system on the same set of hardware devices to be isolated from one another, as if a body had
The introduction of Windows Server 2012 is called "Cloud operating System", presumably this operating system in the virtualization domain, at the network and storage level, in the access and security level will have a strong function. Today to introduce the network card aggr

Today, we are going to introduce NLB, Network Load BalancingNetwork Load Balancing, referred to as NLB, allows you to propagate incoming requests to up to 32 servers, which means you can use up to 32 servers to share external network request services. Network Load Balancing ensures that even under heavy loads they can respond in a very fast time.Network Load Bala
