Tags: statement ros process introduced via bug data com makerHere's a quick introduction to how to create a SQL Server AG (always on availability Group) in Ubuntu Step-by-step, as well as a fill method for pits encountered during configuration. There are currently two types of SQL Server AG available on Linux, one high-availability architecture that uses cluster servers to provide business continuity. This structure includes the Read-scale node. Next, we will introduce this method of building A

nodes.Common deployment modes are: Active-passive primary and Standby mode, active-active dual active mode, cluster mode.(2) So how to build a redundant control node? Or what other ways to achieve high-reliability control?Many people may think of implementing active-passive mode, using a heartbeat mechanism or a similar method for backup, and failover to achieve high reliability. OpenStack does not have multiple control nodes, and pacemaker requires

state of each node, taking this node as a perspective to ensure that the node can take corresponding actions in special cases.2.CRMD components (Cluster Resource Manager, cluster resource Manager, also known as pacemaker): to achieve the allocation of resources, each action of resource allocation through the CRM to achieve, is the core of the formation, The CRM on each node maintains a CIB to define resource-specific properties and which resources ar

The target is to deploy MySQL, Coreseek, Redis, MongoDB, NFS, Varnish, and other services for four new servers. The four servers are divided into two groups, using Linux-HA + Pacemaker for High availability (HA, High-Availablility ). The production server does not install gcc or other compilation tools for security reasons. Therefore, all software compilation tasks are completed on a dedicated compilation machine. After compilation is complete, deploy

Build TFSNameserverHA using CentosBackground Tfs requires compiling with gcc 4.1.2. The two solutions 1 are centos5 (with gcc 4.1.2) and 2 is centos6 to reduce gcc to 4.1.2. I am using the first method to successfully run tfs. The problem arises when using HA. The official requirement is to use heartbeat 3.xand centos5 is 2.x. Choose to compile heartbeat 3 in centos5 successfully, but you also need to compile pacemaker. Some problems may occur during
