Build a mysql Server Load balancer and a high-availability environment and a mysql Server Load balancer Objective: To use two hosts to achieve Mysql load balancing and redundancy, and achieve dual-master-slave mutual backup; Environment: rhel5.8, mysql-5.0.77, keepalived-1.2

Both LVS and Nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you with the advance test. It is a good habit to

one file. The benefits are simple, possibly as long as there are few configurations. However, as the number of servers increases, it becomes very difficult to monitor log files on each server. 2. Logging to a share this method is still available for each server, but they are stored on a central file server through a sharing mechanism, which makes monitoring logs easier. The problem with this scenario is that if the file server is unavailable, a simpl

there is a machine down, it is only one of the db n one of the data can not access it, which we can accept, at least more than before the segmentation of the situation is much better, not the entire DB can not access. In general applications, such machine failure caused by the data is not accessible is acceptable, assuming our system is a high-concurrency e-commerce site? The economic losses caused by single-node machine outages are very serious. In other words, there is still a problem with ou

We introduce the concept of clustering , which I call group, that is, each node of the library we introduce multiple machines, each machine holds the same data, in general, many of these machines load, when there is a downtime situation, The load balancer allocates the

group, which is the node of each library we introduce multiple machines, each of which holds the same data, and in general the load is distributed by multiple machines, and the load balancer distributes the load to the machine that is down when there is an outage. This solves the problem of fault tolerance.As shown, t

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

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. PHP Load Balancer Instance If you want to use

Hi, today we will learn how to use Weave and Docker to build an Nginx reverse proxy/Load balancer server. Weave can create a virtual network that connects Docker containers to each other, enabling cross-host deployment and Autodiscover. It allows us to focus more on the development of the application rather than on the infrastructure. Weave provides such a great environment as if all its containers belong t

and configure, and is easy to test. It can print errors in logs. It takes a long time to configure and test LVS. LVS is highly dependent on the network.3. It can handle high load pressure and stability. In the case of poor hardware, it can support tens of thousands of concurrent requests, and the load is relatively smaller than LVS.4. nginx can detect internal s
