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
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.

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

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.

The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests.
Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different).
The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.

In Linux, the meaning of CPU load and CPU usage indicates that the Nagios alarm information was viewed yesterday. It was found that the CPU load on one of the servers was too heavy and the machine was CentOS.

When we use the top command to see the system's resource usage, we see load average, as shown in. It represents the average workload of the system at 1, 5, and 15 minutes. So what is load? How does it relate to CPU utilization?Load average: The system average load is the load of the CPU, which contains information that is not CPU usage, but rather statistics on t
What is the difference between the server CPU and the normal CPU? Below we find a professional literature, quickly to increase knowledge. Overall, there are six main differences between the server CPU and the common computer CPU, so let's look at it together.
