nginx配置安装

1. 先安装pcre
   pcre作用是让Nginx支持Rewrite功能
   下载地址：https://sourceforge.net/projects/pcre/files/pcre/，选择最新版本进行下载
   下载之后进行解压，并进入到解压目录进行安装
   ./configure    ->   make && make install
   pcre-config --version查看版本，检测是否安装成功
2. 安装Nginx
   下载Nginx，下载地址：http://nginx.org/download/ ，选择最新版本进行下载
   下载之后进行解压，并进入到解压目录进行安装
   ./configure    ->   make && make install  默认安装目录是/usr/local/
    /usr/local/nginx/sbin/nginx -v 查看版本，检测是否安装成功
3. Nginx配置
   创建Nginx运行使用的用户www（名字自己起就行）: groupadd www    ->   useradd -g www-nginx www-nginx
   配置nginx.conf文件，修改成以下内容（在/usr/local/nginx/conf目录下）：

   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/nginx/sbin/nginx -t

4. 配置完后启动Nginx
    /usr/local/nginx/sbin/nginx
5. 最后在浏览器中输入:localhost即可
