Linux environment to install and configure Nginx reverse proxy server

First installed Nginx tossing most of the day beginning when installed the wrong version of the problem has been wrong version also cut can not
later be forced to reinstall the system to finally give I installed a

Linux distributions: CentOS 7

First install the build tools and libraries:

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

Then install pcre library allows Nginx Rewrite support functions:

cd /usr/local/src/ #移动到指定目录
wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz #下载PCRE安装包
tar zxvf pcre-8.35.tar.gz #解压安装包
然后进入安装包目录
./configure #编译安装
make && make install #编译安装

Finally, install Nginx:

wget http://nginx.org/download/nginx-1.6.2.tar.gz #下载Nginx压缩包
tar xzf nginx-1.6.2.tar.gz #解压Nginx源码包
cd nginx-1.6.2 #然后进入解压出的目录
./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35 #编译安装
make #编译安装
make install #编译安装

After installing View Nginx version

/usr/local/webserver/nginx/sbin/nginx -v #查看Nginx版本

Successful installation

Then is configured on the server:

Create Nginx running user www

/usr/sbin/groupadd www
/usr/sbin/useradd -g www www

Will replace /conf/nginx.conf profile for the following:

For example, to configure the number of CPU cores and domain name according to their actual situation

user www www; # 定义Nginx运行的用户和组

worker_processes 1; # 启动进程数 设置值和CPU核心数一致

error_log /usr/local/webserver/nginx/logs/nginx_error.log info; # 全局错误日志的位置和日志级别
#错误日志等级：[debug | info | notice | warn | error | crit]

pid /usr/local/webserver/nginx/nginx.pid; # pid文件位置

worker_rlimit_nofile 65535; # 一个Nginx进程打开的最大文件描述符数目

#工作模式及连接数上限
events
{
  use epoll; # epoll是多路复用IO的一种方式 可大大提高Nginx性能
  worker_connections 65535; # 单个后台进程的最大并发连接数(最大连接数=连接数*进程数)
  multi_accept on; # 尽可能多的接受请求
}

# 设定http服务器 利用其反向代理功能提供负载均衡支持
http
{
  include mime.types; # 设定mine类型 类型由mine.type文件定义
  default_type application/octet-stream; # 默认数据流类型
  log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
               '$status $body_bytes_sent "$http_referer" '
               '"$http_user_agent" $http_x_forwarded_for';

       }

    access_log off;
  }
}

Configuration profiles nginx.conf finished checking the correctness:

/usr/local/webserver/nginx/sbin/nginx -t

Profiles normal

Some common commands:

/usr/local/webserver/nginx/sbin/nginx                      # 启动服务器
/usr/local/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件
/usr/local/webserver/nginx/sbin/nginx -s reopen            # 重启 Nginx
/usr/local/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx

View process:

ps -ef | grep nginx #查看Nginx进程

Conclusion:

This configuration file name I toss most of the day also tried ip domain hosts have also tried to set off in the browser but is not accessible through the domain name
last used ip access success is a success but certainly can not do so otherwise the domain name white bought a
preliminary estimate of the problem may be configured domain name is not mapped successfully led the hour is late tomorrow look and see
