Nginx 在centos linux 安装、部署完整步骤并测试通过

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/

wgethttp://exim.mirror.fr/pcre/pcre-8.02.tar.gz

tar -zxvf pcre-8.02.tar.gz

cd pcre-8.02

./configure && make && make install

3.安装zlib库

cd /usr/local/

wgethttp://zlib.net/zlib-1.2.8.tar.gz

tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8

./configure

make

make install

4.安装ssl

cd /usr/local/

wgethttp://www.openssl.org/source/openssl-1.0.1c.tar.gz

tar -zxvf openssl-1.0.1c.tar.gz

./config

make

make 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/

wgethttp://nginx.org/download/nginx-1.2.8.tar.gz

tar -zxvf nginx-1.2.8.tar.gz

cd nginx-1.2.8

./configure--prefix=/usr/local/nginx

make

make install

--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。

7.重启

/usr/local/nginx/sbin/nginx –s reload

8.修改配置文件

cd /usr/local/nginx/conf

vi nginx.conf

9.常用配置

#nginx运行用户和组

userwww www;

#启动进程,通常设置成和cpu的数量相等

worker_processes4;

#全局错误日志及PID文件

pid /var/run/nginx.pid;

error_log /var/log/nginx/error.log;

events {

#epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能

use epoll;

#单个后台worker process进程的最大并发链接数

worker_connections10240;

}
