技術標籤：nginxnginx

1.nginx功能，可以作為HTTP伺服器，也可作為反向代理伺服器，郵件伺服器。支援FastCGI、SSL、Virtual Host、URL Rewrite、Gzip等功能。並且支援很多第三方的模組擴充套件。在使用nginx過程中我們除了要使用nginx自身的功能之外，我們還需要讓它使用起來更加得心應手和舒服，這時我們可以自己配置nginx日誌顯示，實現服務監聽，訪問統計等。一個好的nginx日誌配置方便我們對服務的監控，負載均衡和session共享可以方便我們橫向擴充套件服務，日誌分割使我們更容易區分每天服務的訪問情況。具體配置如下

1.nginx配置日誌為json格式，方便其它服務抓取資料，實現訪問監聽

	#配置日誌為json格式
	log_format main '{
		  "@timestamp":"$time_local",
		  "host":"$server_addr",
		  "clientip":"$remote_addr",
		  "remote_user":"$remote_user",
		  "request":"$request",
		  "http_user_agent":"$http_user_agent",
		  "size":"$body_bytes_sent",
		  "responsetime":"$request_time",
		  "upstreamtime":"$upstream_response_time",
		  "upstreamhost":"$upstream_addr",
		  "http_host":"$host",
		  "url":"$uri",
		  "domain":"$host",
		  "xff":"$http_x_forwarded_for",
		  "referer":"$http_referer",
		  "status":"$status"
		}';
 

2.nginx配置日誌按照天分割，配置在server裡

		 #日誌按照天分割
		if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})")
			{
				set $year $1;
				set $month $2;
				set $day $3;
				set $hour $4;
				set $minutes $5;
				set $seconds $6;
			}
		access_log  logs/nginx_access_$year-$month-$day.log  main;
 

3.nginx配置負載均衡，使用ip_hash實現session共享

	#負載均衡，使用ip_hash實現session共享
	upstream dianyu_net_server {
         server 102.13.22.223:8080;
         server 102.13.22.224:8080;
		 server 102.13.22.225:8080;
         ip_hash;
		}

4.nginx全部配置如下

#配置啟動使用者為root
user  root;
worker_processes  1;


events {
    worker_connections  1024;
}


http {

	#配置日誌為json格式
	log_format main '{
		  "@timestamp":"$time_local",
		  "host":"$server_addr",
		  "clientip":"$remote_addr",
		  "remote_user":"$remote_user",
		  "request":"$request",
		  "http_user_agent":"$http_user_agent",
		  "size":"$body_bytes_sent",
		  "responsetime":"$request_time",
		  "upstreamtime":"$upstream_response_time",
		  "upstreamhost":"$upstream_addr",
		  "http_host":"$host",
		  "url":"$uri",
		  "domain":"$host",
		  "xff":"$http_x_forwarded_for",
		  "referer":"$http_referer",
		  "status":"$status"
		}';
	#不生效
    #access_log  logs/access.log  main;#1、轉發的日誌檢視
	
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
	
	#負載均衡實現session共享,缺少配置流量分配和健康檢查
	upstream dianyu_net_server {
         server 102.13.22.223:8080;
         server 102.13.22.224:8080;
		 server 102.13.22.225:8080;
         ip_hash;
		}

		server {
		  listen 80;
		  server_name 127.0.0.1;



		  location / {

		 #日誌按照天分割
		if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2})")
			{
				set $year $1;

		}
