nginx的未知的指令「保活」

Question

我使用下面的配置

upstream site { 
    server 127.0.0.1:3000; 
    keepalive 64; 
} 

server { 
    listen 80; 

    error_page 400 404 500 502 503 504 /50x.html; 
    location /50x.html { 
      internal; 
      root /usr/share/nginx/www; 
    } 

    location /static { 
     root /opt/site/static; 
     access_log off; 
     expires max; 
    } 

    location/{ 
     proxy_redirect off; 
     proxy_set_header X-Real-IP   $remote_addr; 
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
     proxy_set_header X-Forwarded-Proto $scheme; 
     proxy_set_header Host     $http_host; 
     proxy_set_header X-NginX-Proxy true; 
     proxy_set_header Connection ""; 
     proxy_http_version 1.1; 
     proxy_pass   http://site; 
     proxy_intercept_errors on; 
    } 
} 

我已經保存它/etc/nginx/sites-available/site.conf和符號鏈接到它的/ etc /啓用站點-/ site.conf，當我重新啓動nginx的它給了我下面的錯誤：

Restarting nginx: [emerg]: unknown directive "keepalive" in /etc/nginx/sites-enabled/site.conf:3

Answer 1

沒有keepalive指令。改爲使用keepalive_timeout。你不能把它放在upsream裏面，在http,server或location裏面使用。

Answer 2

選項「keepalive」由keepalive module提供。而且從1.1.4開始，keepalive功能被包含在主代碼中。
