麒麟海思Linux（Ubuntu）安装编译安装Nginx

Nginx 的集群安装配置，可从 http://nginx.org/en/download.html 网站，下载最新版本 Nginx。

本文版本是nginx-1.8.1.tar.gz。

1、下载nginx-1.8.1.tar.gz上传至/home/nginx目录下
cd home/nginx
tar xzvf nginx-1.8.1.tar.gz
2、进入 Nginx 解压目录，运行编译安装程序。
cd nginx-1.8.1
./configure --prefix=/home/nignx1.8.1 --with-http_stub_status_module     
#--prefix 为安装目录
make
make install
3、进入Nginx的conf目录，根据需要更改监听端口
cd conf
vi nginx.conf
将其中的listen       80;根据需要自行更改端口
4、进入 Nginx 的 sbin 目录，运行 ./nginx –t。
cd /home/nginx1.8.1/sbin/
./nginx –t
5、打开浏览器访问Nginx地址NginxIp:listenPort,如果出现下面页面说明安装成功。

6、停止或重启Nginx。

停止 Nginx：#./nginx -s stop

Nginx重加载：#./nginx -s reload

Nginx下集群配置

进入Nginx的conf目录，编辑nginx.conf文件，简单配置内容如下：
#user  nobody;
worker_processes  1; #进程个数

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    use epoll; #linux 下采用 epoll
    worker_connections  1024; #并发数
}
