nginx搭建过程

Nginx安装部署

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 代理服务器。 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。 一般我们都需要先装pcre, zlib，前者为了重写rewrite，后者为了gzip压缩。1.选定源码目录选定目录 /usr/local/ cd /usr/local/ 2.安装PCRE库cd /usr/local/wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gztar -zxvf pcre-8.21.tar.gzcd pcre-8.21./configuremakemake install 3.安装zlib库cd /usr/local/ wget http://zlib.net/zlib-1.2.8.tar.gztar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8./configuremakemake install 4.安装ssl cd /usr/local/wget http://www.openssl.org/source/openssl-1.0.1c.tar.gztar -zxvf openssl-1.0.1c.tar.gz./configmakemake install 5.安装nginx Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个，下面是把 Nginx 安装到/usr/local/nginx 目录下的详细步骤： cd /usr/local/wget http://nginx.org/download/nginx-1.2.8.tar.gztar -zxvf nginx-1.2.8.tar.gzcd nginx-1.2.8 ./configure --prefix=/usr/local/nginx makemake install
还要装pcre-devel和zlib-devel --with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源码路径。--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源码路径。 6.启动确保系统的 80 端口没被其他程序占用，/usr/local/nginx/sbin/nginx 检查是否启动成功：netstat -ano|grep 80 有结果输入说明启动成功 打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。下面是nginx的 启动、重启、关闭等脚本注意更改路径#!/bin/sh
