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

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.

Installation Steps
Step 1: Obtain the random patch for Solaris 8.
PRNG is not seeded. The following is my solution.First, you must ensure that all the packages required by openssh are installed.1. Sun's patch 112438-01In fact, this patch is installed and sometimes it is not used because 8 does not have a random number device by default.Install the patch to solve this problem, but it is not recommended to install it because it is useless in actual use.

Compiling and installing MySQL under solrais many of my friends may encounter some problems when compiling mysql under sun. now I will sort out the compilation process as follows, hoping to help you.
Environment:
Sun250 + solaris8
Process:
First install the compilation environment of solaris8, go to http://www.sunfreeware.com/download the ghost software:

2.automake-1.4-sol8-spar
To receive the notification, you need to build the apache2 http server under solaris8. The version is 2.26.
So I went.Http://www.sunfreeware.com/indexsparc8.html, Find the required software,At first I was dizzy. I went to the software installation of mongosolaris10, but I could install it ?...Sweaty! Finally, you have to delete it.
