that the domain name blog.s135.com is resolved to an extranet/public virtual ip:61.1.1.3 (VS_SQUID) of the F5 load balancer, there is a server pool (POOL_SQUID) under the virtual IP that contains two real squid servers under the pool ( 192.168.1.11 and 192.168.1.12)?②? If the squid cache misses, the F5 intranet virtual ip:192.168.1.3 (Vs_apache) is requested, and there is a default server pool (Pool_apache

Load balancers are often referred to as four-tier switches or seven-tier switches. The four-layer switch mainly analyzes the IP layer and the TCP/UDP layer to achieve four-layer flow load balancing. In addition to supporting four-tier load balancing, the seven-tier switch also contains information on the analysis application layer, such as HTTP protocol URI or cookie information. First, F5 configuration st

F5 is one of our most popular Server Load balancer products, so here we will introduce its configuration on the actual business platform. Through this case, I hope you will have a clear understanding of the specific use and configuration of this product. For more information, please refer to the following section.I.

Based on the article "Installation and basic configuration of Hadoop2.0" (see http://www.linuxidc.com/Linux/2014-05/101173.htm), this paper continues to introduce hadoop2.0 QJM (Quorum Journal Manager) mode of HA configuration (hadoop2.0 architecture, specific version is hadoop2.2.0).

interrupting the shared access of the previous active node edit store. This prevents any further modifications to the namespace, allowing the new active node to fail over safely. Note: Currently, only manual failover is supported. This means that the HA Namenode cannot automatically detect the failure of the active namenode, but rather by manually initiating the failover. Automatic failure detection and failover will be implemented in future releases

Chd4b1 (hadoop-0.23) for namenode ha installation Configuration Cloudera chd4b1 version already contains namenode ha, the Community also put namenode ha branch HDFS-1623 merge to trunk version, can achieve hot backup of dual namenode, but currently only supports manual switch, does not support automatic switch, switch

operating system hangs, on the one hand may cause the service interruption, on the other hand because the primary node resources can not be freed, and the backup node takes over the resources of the master node, at this time, there are two nodes competing for a resource status.For this problem, you need to enable a module called watchdog in the Linux kernel. Watchdog is a Linux kernel module that determines whether the system is functioning properly by performing a write operation to the/dev/wa

application polls the list. This HA solution is easy to use. First, start a zookeeper cluster and then start the master on different nodes. Note that these nodes must have the same zookeeper configuration (zookeeper URL and directory ).

After configuring multiple dataservers, you need to consider the single point of failure problem of nameserver. This article will introduce how to implement ha for the nameserver of TFS. It is officially recommended to use heartbeat, but the implementation configuration of heartbeat is much more complicated than keepalive, therefore, keepalive is used to implement ha
