Nginx是一款轻量级的网页服务器、反向代理服务器。相较于Apache、lighttpd具有占有内存少，稳定性高等优势。它最常的用途是提供反向代理服务。

# 安装

Nginx的安装依赖于以下三个包，意思就是在安装Nginx之前首先必须安装一下的三个包，注意安装顺序如下：
- SSL功能需要openssl库，直接通过yum安装:
```
yum install openssl
```
  1
- gzip模块需要zlib库，直接通过yum安装:
```
yum install zlib
```
  1
- rewrite模块需要pcre库，直接通过yum安装:
```
 yum install pcre
```

安装Nginx后，安装位置在/etc/nginx/目录下，你可以打开/etc/nginx/conf.d/default.conf查看里面的配置，包括监听端口，域名和nginx访问的根目录；

[root@iZbp156pkpio44mis76wmxZ conf.d]# cat default.conf
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}
