Nginx安装说明

1.介绍

      Nginx 是一个很强大的高性能Web和反向代理服务器，它具有很多非常优越的特性  

2.安装

     2.1 下载

     下载地址:http://nginx.org/en/download.html

      Windows: nginx-1.6.2.zip

      Unix: nginx-1.6.2.tar.gz      

     2.2 解压

         tar zxvf    nginx-1.6.2.tar.gz  [-C {解压目录}]

     2.3 配置

        cd   nginx-1.6.2

       ./configure --prefix={安装目录} --with-http_stub_status_module --without-http_rewrite_module --without-http_gzip_module

       make    

       make install

      2.4 检测

          检查是否安装成功      

          进入安装目录

         ./sbin/nginx -t 

         如果安装成功结果显示如下:

        nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

        nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

      2.5 启动 

           ./sbin/nginx       

          ie 浏览器中输入 http://{目标IP}

        注意，这里nginx监听80端口，所以要在iptables里打开80端口。

        /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

        接着访问这台机器的80的端口，如果请求成功，则说明配置成功。

       为了操作方便，可以自己写一个nginx命令脚本，放到/etc/init.d下，执行方法如下：

启动：service nginx start

停止：service nginx stop

重启：service nginx reconfigure

查看状态：service nginx status

   3.常见问题

   3.1 .安装Nginx时报错 ./configure: error: the HTTP rewrite module requires the PCRE library.

           安装pcre-devel解决问题   yum -y install pcre-devel

  4.配置
