一、简介
Nginx（发音同engine x）是一款由俄罗斯程序员Igor Sysoev所开发轻量级的网页服务器、反向代理服务器以及电子邮件（IMAP/POP3）代理服务器。起初是供俄国大型的门户网站及搜索引擎Rambler（俄语：Рамблер）使用。此软件BSD-like协议下发行，可以在UNIX、GNU/Linux、BSD、Mac OS X、Solaris，以及Microsoft Windows等操作系统中运行。
二、特点
Nginx是一款面向性能设计的HTTP服务器，相较于Apache、lighttpd具有占有内存少，稳定性高等优势。与旧版本（<=2.2）的Apache不同，nginx不采用每客户机一线程的设计模型，而是充分使用异步逻辑，削减了上下文调度开销，所以并发服务能力更强。整体采用模块化设计，有丰富的模块库和第三方模块库，配置灵活。 在Linux操作系统下，nginx使用epoll事件模型，得益于此，nginx在Linux操作系统下效率相当高。同时Nginx在OpenBSD或FreeBSD操作系统上采用类似于epoll的高效事件模型kqueue。
-
可大量平行处理
Nginx在官方测试的结果中，能够支持五万个平行连接，而在实际的运作中，是可以支持二万至四万个平行链接。
-
nginx 的模块
整体采用模块化设计是nginx的一个重大特点，甚至http服务器核心功能也是一个模块。要注意的是：nginx的模块是静态的，添加和删除模块都要对nginx进行重新编译，这一点与Apache的动态模块完全不同。
-
与PHP的集成
自PHP-5.3.3起，PHP-FPM加入到了PHP核心，编译时加上--enable-fpm即可提供支持。 PHP-FPM以守护进程在后台运行，Nginx响应请求后，自行处理静态请求，PHP请求则经过fastcgi_pass交由PHP-FPM处理，处理完毕后返回。 Nginx和PHP-FPM的组合，是一种稳定、高效的PHP运行方式，效率要比传统的Apache和mod_php高出不少。
PHP-FPM不支持Windows平台，由于没有fastcgi进程管理器管理php-cgi.exe，因此一旦php-cgi.exe崩溃退出，前端将失去响应，这时Nginx会返回"
你正在访问的页面暂时不可用,请稍后再试"。
的错误信息。 因此在Windows上用Nginx和php-cgi.exe组合来运行PHP的方式并不可靠，稳定性有待提高。

七、安装memcached
1、系统环境
-
OS :Centos6.5 x86_64
-
memcached：memcached-1.4.17
-
己安装的包组
|
1
2
|
# yum groupinstall "Development Tools" "Server Platform Deveopment" -y
#yum install -y libevent-devel
|
2、安装过程
-
下载memcached
|
1
|
[root@slave download]# wget http:
//www.memcached.org/files/memcached-1.4.17.tar.gz

Memcached启动参数说明：
-d 选项是启动一个守护进程，
-m 是分配给Memcache使用的内存数量，单位是MB，默认64MB
-M return error on memory exhausted (rather than removing items)
-u 是运行Memcache的用户，如果当前为root 的话，需要使用此参数指定用户。
-l 是监听的服务器IP地址，默认为所有网卡。
-p 是设置Memcache的TCP监听的端口，最好是1024以上的端口
-c 选项是最大运行的并发连接数，默认是1024
-P 是设置保存Memcache的pid文件
-f <factor> chunk size growth factor (default: 1.25)

安装完成的时候会生成一个memcache.so模块的路径，记得把这个路径记下来写到php的配置文件中，编辑/etc/php.ini，在“动态模块”相关的位置添加如下一行来载入memcache扩展：extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/memcache.so然后就可以写一个测试页面，来测试php是否能与后端缓存服务器联系了.

-
测试结果
-
在Mamcached服务器上查看一下此条请求是否记录了
八、性能监控
-
安装memadin

[root@essun download]# http:
//www.junopen.com/memadmin/memadmin-1.0.12.tar.gz
[root@essun download]# tar xf memadmin-
1.0
.
12
.tar.gz
[root@essun download]# cd memadmin
[root@essun memadmin]# ls
apps images index.php LICENSE.txt views
config.php
include
langs README.txt
[root@essun download]# mv memadmin /usr/html/
|
此memadin目录也要放在nginx的站点目录下
-
配置并测试
-
点“开始管理”
这样就可以对memcached进行监控了
