log cannot be written to the problem that eventually causes the entire application to crash.3. Logging to logging server you can use a logging software, such as a syslog, to write all the logs to a central server. Although this method requires more configuration, he also provides the most robust solution.

Today, every time you make a mobile phone call, read the news on the main portal website, and make an online bank transaction, your access information will go through the Server Load balancer device, it ensures massive network application access in the background. We can see that it is by our side.
Sudden increase in network traffic: the emergence of independent Load
With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load Web Services.Under the idea of Server Load
One, LVS three kinds of packet forwarding methodLVS provides three packet forwarding methods: NAT (Network address mapping), IP tunneling (IP tunneling), direct Routing (straight route)Different forwarding mode determines the network structure of different cluster, and the following three kinds of forwarding methods are respectively started:1. NAT (Network address mapping):The NAT mode can support any operating system, as well as private networks, and requires only one Internet IP address, but t
services. The more famous is www.linux.com and www.real.com.II. system Structure of LVSThe server cluster system with LVS is composed of three parts: the most front-end load Balancing layer (Loader Balancer), the middle server group layer, with server array, the lowest data sharing storage layer, represented by shared storage. All applications are transparent to the user, and the user is only using the hig
Now, basically all enterprises use the network for daily work. In the network operation of an enterprise, the transmission and data sending and receiving processes are not evenly distributed. Then, using Server Load balancer technology can achieve a balanced concept. So how to implement it? If it is not realistic to purchase large load balancing equipment, softwa

Server Load balancer allocates the load to the machine that goes down. In this way,
The Fault Tolerance problem is solved. Therefore, we introduced the concept of cluster and embedded it into our framework to become part of the framework.
As shown in, the entire data layer consists of three clusters: Group1, Group2, and group3. these three clusters are the resu

, improving network flexibility and availability.
Server Load balancer has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the user's waiting for response time. Second, computing of a single heavy load is distributed to multiple nodesPoint devices perform parallel p
