Nginx(“engine x”)是一款是由俄罗斯的程序设计师Igor Sysoev所开发高性能的 Web和 反向代理 服务器,也是一个 IMAP/POP3/SMTP 代理服务器。
在高连接并发的情况下,Nginx是Apache服务器不错的替代品。

Nginx 安装

  • 一、安装编译工具及库文件
    yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel
    
  • 二、安装 PCRE PCRE 作用是让 Nginx 支持 Rewrite 功能。
    1、下载 PCRE 安装包,下载地址:http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
     wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
    

    2、解压安装包:

     tar zxvf pcre-8.35.tar.gz
    

    3、进入安装包目录

     cd pcre-8.35
    

    4、编译安装

     ./configure
     make && make install
    

    5、查看pcre版本

     pcre-config --version
    
  • 三、安装 Nginx
    1、下载 Nginx,下载地址:http://nginx.org/download/nginx-1.6.2.tar.gz
     wget http://nginx.org/download/nginx-1.6.2.tar.gz
    

    2、解压安装包

     tar zxvf nginx-1.6.2.tar.gz
    

    3、进入安装包目录

     cd nginx-1.6.2
    

    4、编译安装

     ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
     make
     make install
    

    5、查看nginx版本

     /usr/local/webserver/nginx/sbin/nginx -v
    

    到此,nginx安装完成。

Nginx 配置

  • 创建 Nginx 运行使用的用户 www
     /usr/sbin/groupadd www 
     /usr/sbin/useradd -g www www
    
  • 配置nginx.conf ,将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容
    cat /usr/local/webserver/nginx/conf/nginx.conf
    
user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll;
  worker_connections 65535;
}
http
{
  include mime.types;
  default_type application/octet-stream;
  log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
               '$status $body_bytes_sent "$http_referer" '
               '"$http_user_agent" $http_x_forwarded_for';
  
#charset gb2312;
     
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 8m;
     
  sendfile on;
  tcp_nopush on;
  keepalive_timeout 60;
  tcp_nodelay on;
  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;
  gzip on; 
  gzip_min_length 1k;
  gzip_buffers 4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_types text/plain application/x-javascript text/css application/xml;
  gzip_vary on;
 
  #limit_zone crawler $binary_remote_addr 10m;
 #下面是server虚拟主机的配置
 server
  {
    listen 80;#监听端口
    server_name localhost;#域名
    index index.html index.htm index.php;
    root /usr/local/webserver/nginx/html;#站点目录
      location ~ .*\.(php|php5)?$
    {
      #fastcgi_pass unix:/tmp/php-cgi.sock;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
    {
      expires 30d;
  # access_log off;
    }
    location ~ .*\.(js|css)?$
    {
      expires 15d;
   # access_log off;
    }
    access_log off;
  }

}
  • 检查配置文件nginx.conf的正确性命令:
     /usr/local/webserver/nginx/sbin/nginx -t
    

Nginx 验证

Nginx 启动命令如下:

 /usr/local/webserver/nginx/sbin/nginx

访问站点: 从浏览器访问我们配置的站点ip

Nginx 相关命令

/usr/local/webserver/nginx/sbin/nginx
/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
