Question

我在socket.io和nginx配置方面遇到了一些问题。

在网站流量增加后，我们发现有时套接字会出现这种错误：错误提供静态/socket.io.js而我们丢失了套接字连接。

点击几次后，F5 socket.io已连接。我们有100-150个用户/选择它并不多，但我们仍然在socket.io中遇到性能问题。

我们阅读了很多关于nginx，fpm性能的文章，但没有任何帮助。

这很棘手，因为任何其他文件（js，css等）永远不会得到500 Bad gateway，只有socket / socket.io.js才能得到它。

如果有人有类似的问题？

我对socket.io的nginx配置如下所示：

server {

           listen 443 ssl;
           ssl_certificate /etc/ssl/ao-certs/socket/bundle.pem;
           ssl_certificate_key /etc/ssl/ao-certs/socket/private.key;
           ssl_ciphers RC4:HIGH:!aNULL:!MD5:!ADH:!kEDH;
           ssl_prefer_server_ciphers on;
           server_name socket.customericare.com;
           location / {
                    proxy_pass http://127.0.0.1:8081; #this is the ip:port where your node app runs root /var/www/yoursitename; expires 30d; #uncomment this is you want to name an index file: #index index.php index.html;
                    proxy_http_version 1.1;
                    proxy_set_header Upgrade $http_upgrade;
                    proxy_set_header Connection "upgrade";
                    proxy_set_header Host $host;
                    access_log off;
            }
    }

nginx app config：

server {
       listen  443 ssl;
       ssl_certificate /etc/ssl/ao-certs/app/bundle.pem;
       sssl_certificate_key /etc/ssl/ao-certs/app/private.key;
       server_name app.customericare.com;
        index index.php index.html index.htm;
access_log off;

  location / {
        root /var/www/vhosts/app.customericare.com/;
        index index.php index.html;
        try_files $uri $uri/ @rewrite;
  }

  # static file 404's aren't logged and expires header is set to maximum age
  location ~* \.(jpg|jpeg|gif|css|png|js|ico|html)$ {
    root /var/www/vhosts/app.customericare.com/;
    access_log off;
    expires max;
    try_files $uri @rewrite;
  }
   location ~ \.php$ {
    # By all means use a different server for the fcgi processes if you need to
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_intercept_errors on;
        fastcgi_param SCRIPT_FILENAME /var/www/vhosts/app.customericare.com/$fastcgi_script_name;
        fastcgi_param   SERVER_NAME     app.customericare.com;
        fastcgi_buffers 8 16k;
        fastcgi_buffer_size 32k;
  }

在node.js（pm2）中，当我重新启动进程时，我有大约20-30MB的内存使用量。几秒后，它增加到~130MB。

socket.io，nginx，错误提供静态，增加流量
