Linux中安裝Nginx

1、安裝編譯文件及庫文件

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

2、安裝PCRE，Nginx的rewrite的偽靜態匹配規則需要用到正則表達式，PCRE就是起到這個作用。

　　下載地址：wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

　　如果wget沒有安裝的話，需要先安裝wget，yum -y install wget.  wget是Linux環境下的下載工具。wget命令的使用見此文章：http://www.cnblogs.com/cindy-cindy/p/6847502.html

3、解壓pcre安裝包：tar -zxvf pcre-8.35.tar.gz

4、進入安裝目錄，編譯安裝

　　cd pcre-8.35

　　./configure

　　make && make install

5、查看pcre版本

　　pcre-config --version

6、下載Nginx

　　wget http://nginx.org/download/nginx-1.6.2.tar.gz

7、解壓併進入安裝包

8、編譯安裝

　　./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

9、查看Nginx版本

10、Nginx配置

　　　1、創建Nginx 運行使用的用戶

　　　　　/usr/sbin/groupadd www

　　　　　/usr/sbin/useradd -g www www

　　　2、配置nginx.conf ，將/usr/local/webserver/nginx/conf/nginx.conf替換為以下內容

user www www;
worker_processes 2; #設置值和CPU核心數一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日誌位置和日誌級別
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 $binary_remote_addr 10m;
 #下麵是server虛擬主機的配置
 server
  {
    listen 80;#監聽埠
    server_name localhost;#功能變數名稱
    index index.html index.htm index.php;
    root /usr/local/webserver/nginx/html;#站點目錄
      location ~ .*\.(php|php5)?$
    {
      #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;
  }

}

　　　　3、檢查nginx.conf配置文件的正確性

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