I. Basic description of Load Balancing
1.1 Why to use Nginx
With this image we can see that nginx performance is significantly better than Apache and lighttpd, so we use Nginx to load balance.
So how do we achieve load balancing? Take a look at the architecture diagram below.
1.2 Load-Balanced architecture diagram
With this architecture diagram, we can see that we are doing load balancing through an Nginx proxy server + two Web servers.

1 IntroductionI have a binary file that is a program that cannot be executed on Ubuntu system and the results obtained by using the file command are:Graphgen:elf 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically linked (uses shared libs), not strippedBased on the above tips, I thought about installing the Soloari SPARC series operating system on Virtual box VMS because the hints above are binaries
Departmental machine upgrades, the elimination of a number of older machines, including the Ultra series of SPARC models, 64M memory, 2.1G hard disk, Solaris 9 has indicated that it does not support 64m memory, installed Solaris 8 and really lazy to play patch, not to mention, so small hard drive , the Solaris 8 has been installed and there is no room for service, and Solaris is not as easy to use as Linux for workstations. When using Gentoo, I have s

Apache|mysql used to microsft things, people also become more and more lazy:-) but still want Microsoft not to fall ~ ~, what new software package to get the first is can't wait to the CD-ROM drive inside a plug, if it can automatically run (Hey, The service is really thoughtful) jump directly to the next step, if not the words to find setup.exe,install.exe ... Anyway it's easy to fix, and then go to brew a cup of tea, slowly sit down to the side of tea and constantly hit enter, and occasionally
If you only know the concept of CPU, then it is impossible to understand the CPU topology. In fact, in the NUMA architecture, the concept of CPU is from big to small: Node, Socket, Core, Logical Processor. With the development of multicore technology, we encapsulate multiple CPUs together, a package commonly referred to as a socket. Where the physical processor is plugged in, it looks like this: Each core

Next, is to format the partition
MKE2FS/DEV/SDA1//Format the first partition (boot partition) into ext2 format, which is also the Linux default format
Mke2fs-j/DEV/SDA4//format the fourth partition (root partition) in ext3 format, remember that because of SPARC's particularity, our Sda3 is whole disk, so do not habitually think of only 3 partitions, so sda3 to the format.

I will upload my new book "self-writing processor" (not published yet). Today is the tenth article. I try to write it every Thursday.
This chapter describes how to implement the openmips processor for teaching. This chapter provides a blueprint for the openmips System for the tutorial version. First, it introduces the design objectives of the system. It details the 5-level pipelines implemented by the ope
The annotations in Java are a magical thing that you don't know yet. You can see the custom annotations (Annotation) for the next hour. Now a lot of Android libraries are implemented using annotations, such as butterknife, we do not want to learn, we learn the note processor, we try to write a simple similar to the butterknife of things to bind the control.What is an annotation processor? The annotation
Java thread exception processor, Java thread processor
Thread. UncaughtExceptionHandler is a static internal interface of the Thread class. This interface has only one method:
Void uncaughtException (Thread t, Throwable e), where t represents the Thread with an exception and the exception thrown by the e-table.
If an unhandled exception is thrown during thread execution, the corresponding unhandled exceptio
