Jenkins 服务在节点 js 构建期间完全停止，在 Ubuntu 上使用 nginx 设置获得 502 错误网关

Question

我已经在 Ubuntu VPS 上安装了 Jenkins 并且我正在构建 nodejs，这在某些时候会触发 nginx 中的 502 错误网关并且 Jenkis 服务停止。

构建似乎随机停止，有时在安装 npm 模型时，有时在使用 gulp 等时。

我必须手动重新启动它（sudo service jenkins restart）。

这是构建的控制台输出：

502 Bad Gateway

nginx/1.4.6 (Ubuntu)

问题是，当 Jenkis 失败时，它不会在我的构建日志中记录任何内容，所以我不知道发生了什么。

我在网上看到你应该从 nginx.conf 增加超时，所以我在配置文件中添加了以下内容：

http {

        ##
        # Increased timeout to fix 502 bad gateway error
        ##
        fastcgi_buffers 800 10006k;
        fastcgi_buffer_size 1000k;
        fastcgi_connect_timeout 999999;
        fastcgi_send_timeout 999999;
        fastcgi_read_timeout 999999;


Also, in nginx, sites-available, I have the following configuration:




server {
        listen 80;
        server_name jenkins.domain.com;

        ignore_invalid_headers off;

        location / {
                proxy_set_header        Host $host;
                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_pass              http://127.0.0.1:8080;
                proxy_connect_timeout   999999999999;
                proxy_send_timeout      999999999999;
                proxy_read_timeout      999999999999;
        }
}

你有什么想法？

正如本线程中所解释的，您可以增加内存，/etc/default/jenkins您可以在其中调整以下标志

JAVA_ARGS="-Xmx256m" # Choose your desired memory instead of 256
