nginx
Nginx is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Igor Sysoev started development of Nginx in 2002, with the first public release in 2004. Nginx now hosts nearly 7.67% (35.5M) of all domains worldwide.
Nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.
Nginx is one of a handful of servers written to address the C10K problem. Unlike traditional servers, Nginx doesn't rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but more importantly, predictable amounts of memory under load.
Even if you don't expect to handle thousands of simultaneous requests, you can still benefit from Nginx's high-performance and small memory footprint. Nginx scales in all directions: from the smallest VPS all the way up to clusters of servers.
Nginx powers several high-visibility sites, such as WordPress, Hulu, Github, Ohloh, SourceForge, WhitePages and TorrentReactor.
一、安装nginx时必须先安装相应的编译工具
yum -y install gcc gcc-c++ autoconf automake
yum -y install zlib zlib-devel mod_ssl openssl openssl-devel pcre-devel
建立nginx 组
groupadd -r nginx
useradd -g nginx -M -s /sbin/nologin -r nginx
id nginx
zlib:nginx提供gzip模块,需要zlib库支持
openssl:nginx提供ssl功能
pcre:支持地址重写rewrite功能
二、下载安装包并解压
wget http://nginx.org/download/nginx-1.8.1.tar.gz
tar -zxvf nginx-1.8.1.tar.gz
三、编译安装
cd nginx-1.8.1
./configure \
--prefix=/etc/nginx \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx.pid \
--lock-path=/var/run/nginx.lock \

--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp \
--http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp \
--http-scgi-temp-path=/var/cache/nginx/scgi_temp \
--user=nginx --group=nginx \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_sub_module \
--with-http_dav_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_stub_status_module \
--with-http_auth_request_module \
--with-threads
四、make && make install
五、nginx启动脚本
官方文档:http://wiki.nginx.org/RedHatNginxInitScript
Should work on RHEL, Fedora, CentOS. Tested on CentOS 5.
Save this file as /etc/init.d/nginx
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
