Nginx 0.7.x + PHP 5.2.6 (FastCGI) + MySQL 5.1 in 128M Small memory VPS Server Configuration Optimization Large | Medium | Small [2008-10-28 16:55 | by Zhang Banquet] [Article Zhang Banquet this version: v1.0 last modified: 2008.10.28 reproduced Please specify the original link: http://blog.zyan.cc/post/375/]
The VPS (full name Virtual private server) is the use of the latest virtualization technology to create multiple isolated virtual private hosts on a single physical server. They share hardware, software licenses, and management resources with maximum efficiency. For its users and applications, each VPS platform runs and manages exactly the same as a standalone host, since 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 The most important indicator is the size of the memory, multiple VPS server can share a CPU, but cannot share the same block of memory. The larger the memory, the more expensive the price.
Below, take the VPS of my blog as an example, introduced in 128M memory to Nginx 0.7.x + PHP 5.2.6 (FastCGI) + MySQL 5.1 optimization.
As for Nginx + PHP + MySQL installation configuration, see: "Nginx 0.7.x + php 5.2.6 (FastCGI) build 10 times times more than Apache Web Server (4th edition)"
Optimized effect:
1 Nginx processes that provide HTTP services occupy 11M of physical memory, 5 php-cgi processes each occupy 8M or so of physical memory, 1 MySQL servers occupy 7M of physical memory, plus two memory-intensive nginx and php-cgi parent process, Nginx + PHP + The MySQL series consumes only 47.7% of the 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 of memory VPS has enough. Overall, after optimized, 128M memory VPS running Nginx + PHP + MySQL effect is good. Of course, it would be much better if you had money to buy a VPS with bigger memory.
the optimizations are as follows:
one, the increase of 256M swap swap files
1. Create and activate swap swap files
cd/var/
DD If=/dev/zero of=swapfile bs=1024 count=262144
/sbin/mkswap Swapfile
/sbin/swapon Swapfile
2, add to the Fstab file to let the system boot automatically start
Vi/etc/fstab
Add the following at the end:
Reference/var/swapfile swap defaults 0 0

Second, the Nginx 0.7.19 main configuration file (nginx.conf) optimization

third, the configuration optimization of PHP 5.2.6 (FastCGI)
1, php.ini configuration file on the Eacelerator optimization. Use only 1M of shared memory, delete all script caches that are inaccessible in the last 3,600 seconds, and use disk-assisted caching.

2, php-fpm.conf Configuration optimization
Modify the two items, one is to modify the following line, the number of php-cgi processes started from the original 128 changed to 5:
Reference <value name= "Max_children" >5</value>
The second is to modify the following line to change the TCP mode to UNIX socket mode:
Reference <value name= "Listen_address" >/tmp/php-cgi.sock</value>
iv. MySQL 5.1.26 configuration Optimization
1. Using the following parameters to compile the installed MySQL 5.1 default support 4 storage engines: CSV, Mrg_myisam, memory, MYISAM, does not support InnoDB storage engine. The MyISAM storage engine is recommended here because memory is limited and InnoDB consumes large memory.
./configure--prefix=/usr/local/webserver/mysql/--enable-assembler--with-extra-charsets=complex-- Enable-thread-safe-client--with-big-tables--with-readline--with-ssl--with-embedded-server--enable-local-infile
Make && make install
