Let’s take a look at the Discuz installation and configuration process in the LNMP environment:
1. Configure nginx

vim /usr/local/nginx/etc/nginx.conf

user nginx;
 worker_processes 1; 
#error_log logs/error.log;
 #error_log logs/error.log notice;
 error_log logs/error.log info;
events {
  worker_connections 1024;
 }
http {
  include    mime.types;
  server_tokens off;
  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"';
  access_log logs/access.log main;
  sendfile    on;
  keepalive_timeout 65;
  client_header_buffer_size 32k;          
  large_client_header_buffers 4 32k;
   #客户请求头缓冲大小 nginx默认会用client_header_buffer_size这个buffer来读取header值，如果header过大，它会使用large_client_header_buffers来读取如果设置过小HTTP头/Cookie过大 会报400 错误 nginx 400 bad request求行如果超过buffer，就会报HTTP 414错误(URI Too Long)nginx接受最长的HTTP头部大小必须比其中一个buffer大，否则就会报400的HTTP错误(Bad Request)。
  client_max_body_size 8m;              #最大上传附件8MB
  client_body_buffer_size 128k;           #缓冲区代理缓冲用户端请求的最大字节数
  keepalive_timeout    60;
  tcp_nopush   on;
  tcp_nodelay  on;
  gzip on; 
  gzip_min_length 1k;
  gzip_buffers   4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  include vh/bbs.yourich.com.cn.conf;
 }
mkdir /usr/local/nginx/etc/vh
 vim /usr/local/nginx/etc/vh/discuz.conf
upstream  bbs.test.com
 {
  server 127.0.0.1;
  check interval=3000 rise=2 fall=5 timeout=1000 type=http;  
   #interval检测间隔时间，单位为毫秒
   #rsie请求2次正常的话，标记此realserver的状态为up
   #fall表示请求5次都失败的情况下，标记此realserver的状态为down
   #timeout为超时时间，单位为毫秒
  check_http_send "GET / HTTP/1.1\r\nHOST:\r\n\r\n";
  check_http_expect_alive http_2xx http_3xx http_4xx;
 }
server {
  listen 80;
  server_name bbs.test.com;
  index index.html index.php;
  root /www/discuz;
  access_log logs/bbs_access.log main;
  error_log logs/bbs_error.log;
  location ~ .*\.(jpg|jpeg|png|gif\js|css)$ {
    root /www/discuz;
    access_log off;
  }
  location / {
    try_files $uri $uri/ /index.php?$args;
  }
  location ~.*\.(php)?$ {
    expires -1s;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    try_files $uri = 404;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME /www/discuz$fastcgi_script_name;
    fastcgi_param QUERY_STRING  $query_string;
    fastcgi_param REQUEST_METHOD $request_method;
    fastcgi_param CONTENT_TYPE  $content_type;
    fastcgi_param CONTENT_LENGTH $content_length;
  }
}
