Question

在尝试实施upload progress module时，以下服务器配置导致打开文件太多错误

2014/11/19 12:10:34 [alert] 31761#0: *1010 socket() failed (24: Too many open files) while connecting to upstream, client: 127.0.0.1, server: xxx, request: "GET /documents/15/edit HTTP/1.0", upstream: "http://127.0.0.1:80/documents/15/edit", host: "127.0.0.1"
2014/11/19 12:10:34 [crit] 31761#0: *1010 open() "/usr/share/nginx/html/50x.html" failed (24: Too many open files), client: 127.0.0.1, server: xxx, request: "GET /documents/15/edit HTTP/1.0", upstream: "http://127.0.0.1:80/documents/15/edit", host: "127.0.0.1"

以下是生成冲突的服务器块的相关部分乘客启用; rails_env开发; root / home / user / app / current / public;

    # redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

    location / {
        # proxy to upstream server
        proxy_pass http://127.0.0.1;
        proxy_redirect default;

        # track uploads in the 'proxied' zone
        # remember connections for 30s after they finished
        track_uploads proxied 30s;
    }

    location ^~ /progress {
        # report uploads tracked in the 'proxied' zone
        report_uploads proxied;
    }

作为nginx的相对n00b，我不理解这会产生太多文件错误。我假设错误页面仅用于500-504服务器错误...

首先检查并增加root shell中的打开文件限制（系统范围内，通常为1024）：

# ulimit -n
# ulimit -n 16384

然后你可以增加nginx的开放文件限制（主要上下文，nginx.conf的顶部）：

worker_rlimit_nofile 16384

然后重启nginx）
