简介
Nginx("engine x") 是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru站点开发的，第一个公开版本0.1.0发布于2004年10月4日。其将源代码以类BSD许可证的形式发布，因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。2011年6月1日，nginx 1.0.4发布。
Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件（IMAP/POP3）代理服务器，并在一个BSD-like协议下发行。由俄罗斯的程序设计师Igor Sysoev所开发，供俄国大型的入口网站及搜索引擎Rambler（俄文：Рамблер）使用。其特点是占有内存少，并发能力强，事实上nginx的并发能力确实在同类型的网页服务器中表现较好，中国大陆使用nginx网站用户有：百度、京东、新浪、网易、腾讯、淘宝等。

安装
1、环境
[root@test ~]# lsb_release -a LSB Version: :core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch Distributor ID: EnterpriseEnterpriseServer Description: Enterprise Linux Enterprise Linux Serverrelease 5.8 (Carthage) Release: 5.8 Codename: Carthage
2、安装依赖包
[root@test ~]# yum install autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc –y
3、 安装nginx和相关模块
[root@test ~]# cd /usr/local/src/ [root@test src]# wgethttp://nginx.org/download/nginx-1.8.1.tar.gz [root@test src]# wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz [root@test src]# tar –xzvf nginx-1.8.1.tar.gz [root@test src]# tar –xzvf ngx_cache_purge-2.3.tar.gz [root@test src]# cd nginx-1.8.1 [root@test src]# ./configure --user=www --group=www --prefix=/usr/local/nginx --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module --with-http_gzip_static_module --with-http_sub_module --add-module=../ngx_cache_purge-2.3 [root@test src]# make && make install

4、 Nginx启停
1、 Nginx启停 启动 /usr/local/nginx/nginx 2、停止 信号名 作用描述 TERM, INT 快速关闭程序，中止当前正在处理的请求 QUIT 处理完当前请求后，关闭程序 HUP 重新加载配置，并开启新的工作进程，关闭就的进程，此操作不会中断请求 USR1 重新打开日志文件，用于切换日志，例如每天生成一个新的日志文件 USR2 平滑升级可执行程序 WINCH 从容关闭工作进程 [root@test src]# kill -QUIT `cat/usr/local/nginx/nginx.pid` [root@test src]# kill -HUP `cat /usr/local/nginx/nginx.pid` [root@test src]# kill -WINCH `cat /usr/local/nginx/nginx.pid` 3、强制停止 [root@test src]# kill -9 `cat /usr/local/nginx/nginx.pid`
