Nginx 安裝配置

Nginx 安裝配置

Nginx("engine x")是一款是由俄羅斯的程式設計師Igor Sysoev所開發高效能的 Web和 反向代理 伺服器,也是一個 IMAP/POP3/SMTP 代理伺服器。

在高連線併發的情況下,Nginx是Apache伺服器不錯的替代品。


Nginx 安裝

系統平臺:CentOS release 6.6 (Final) 64位。

一、安裝編譯工具及庫檔案

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

二、首先要安裝 PCRE

PCRE 作用是讓 Nginx 支援 Rewrite 功能。

1、下載 PCRE 安裝包,下載地址: http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

[[email protected] src]# cd /usr/local/src/
[[email protected] src]# wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

2、解壓安裝包:

[[email protected] src]# tar zxvf pcre-8.35.tar.gz

3、進入安裝包目錄

[[email protected] src]# cd pcre-8.35

4、編譯安裝

[[email protected] pcre-8.35]# ./configure
[[email protected] pcre-8.35]# make && make install

5、檢視pcre版本

[[email protected] pcre-8.35]# pcre-config --version

安裝 Nginx

1、下載 Nginx,下載地址:https://nginx.org/en/download.html

[[email protected] src]# cd /usr/local/src/
[[email protected] src]# wget http://nginx.org/download/nginx-1.6.2.tar.gz

2、解壓安裝包

[[email protected] src]# tar zxvf nginx-1.6.2.tar.gz

3、進入安裝包目錄

[[email protected] src]# cd nginx-1.6.2

4、編譯安裝

[[email protected] nginx-1.6.2]# ./configure --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
[[email protected] nginx-1.6.2]# make
[[email protected] nginx-1.6.2]# make install

5、檢視nginx版本

[[email protected] nginx-1.6.2]# /usr/local/webserver/nginx/sbin/nginx -v

到此,nginx安裝完成。


Nginx 配置

建立 Nginx 執行使用的使用者 www:

[[email protected] conf]# /usr/sbin/groupadd www 
[[email protected] conf]# /usr/sbin/useradd -g www www

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

[[email protected] conf]#  cat /usr/local/webserver/nginx/conf/nginx.conf

user www www;
worker_processes 2; #設定值和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;

  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 $binary_remote_addr 10m;
 #下面是server虛擬主機的配置
 server
  {
    listen 80;#監聽埠
    server_name localhost;#域名
    index index.html index.htm index.php;
    root /usr/local/webserver/nginx/html;#站點目錄
      location ~ .*\.(php|php5)?$
    {
      #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;
  }

}

檢查配置檔案nginx.conf的正確性命令:

[[email protected] conf]# /usr/local/webserver/nginx/sbin/nginx -t

啟動 Nginx

Nginx 啟動命令如下:
