For its users and applications, each VPS platform runs and manages exactly the same as a stand-alone host, because each VPS can be restarted independently and has its own root access, user, IP address, memory, process, file, application, System function library, and configuration file.
VPS Server is the most important indicator of memory size, multiple VPS servers can share a CPU, but can not share the same block of memory. The greater the memory, the more expensive the price.
Below, take the VPS where my blog is located for example, to introduce the optimization of Nginx 0.7.x + PHP 5.2.6 (FastCGI) + MySQL 5.1 under 128M RAM.
As for Nginx + PHP + MySQL installation configuration, see: "Nginx 0.7.x + php 5.2.6 (FastCGI) to build 10 times times more than Apache Web Server (4th edition)"
Optimized effect:
The 1 Nginx processes that provide HTTP services occupy 11M of physical memory, 5 php-cgi processes each occupy 8M of physical memory, 1 MySQL servers occupy 7M physical memory, plus two memory-intensive Nginx and php-cgi parent processes, Nginx + PHP + The MySQL series takes up only 47.7% of physical memory, or 62M of physical memory (128M * 47.7%≈62m).
In addition, the VPS server system itself and other programs will also use some memory, but 128M memory VPS is sufficient. Overall, after optimized, 128M memory VPS Run Nginx + PHP + MySQL effect is good. Of course, if you have money to buy a larger memory vps, it would be better.
the optimizations are as follows:
One, add 256M swap file
1, create and activate swap file
DD If=/dev/zero of=swapfile bs=1024 count=262144
/sbin/mkswap Swapfile
/sbin/swapon Swapfile
2, add to the Fstab file to allow the system to boot automatically
Add the following at the end:
/var/swapfile Swap Defaults 0 0
Nginx 0.7.19 Main configuration file (nginx.conf) optimization
