Question

我在我的Red Hat Enterprise 6.3上安装了Jenkins。 jenkins通过侦听端口public void paintComponent(Graphics g) { initgr(); showGrid(g); if(ready) { drawLine(g, (int) points.get(points.size() - 2).getX(), (int) points.get(points.size() - 2).getY(), (int) points.get(points.size() - 1).getX(), (int) points.get(points.size() - 1).getY()); } }来运行。

但是，我无法通过网络浏览器或cURL连接到Jenkins。 HTTP连接的TCP连接是＆＃34; ESTABLIASHED＆＃34;，但HTTP GET请求永远等待，Web浏览器继续加载。

[root@linux]# service jenkins status
jenkins (pid  7526) is running...

JENKINS_PORT="8080"
JENKINS_LISTEN_ADDRESS="0.0.0.0"

nmap扫描也很好看：

 [root@linux]# netstat -an | grep 8080
    tcp        0      0 :::8080                     :::*                        LISTEN

这是一个网络问题。 jenkins的默认http连接超时为10秒，但请求'/ pluginManager / plugins'的成本超过10秒，因为响应大约为500KB，非常大。

var pluginManagerErrorTimeoutMillis = 10 * 1000;
...
exports.availablePlugins = function(handler) {
jenkins.get('/pluginManager/plugins', function(response) {
    if(response.status !== 'ok') {
        handler.call({ isError: true, errorMessage: response.message });
        return;
    }

    handler.call({ isError: false }, response.data);
}, {
    timeout: pluginManagerErrorTimeoutMillis,
    error: function(xhr, textStatus, errorThrown) {
        handler.call({ isError: true, errorMessage: errorThrown });
    }
});
};

您可以通过浏览器的开发人员工具更改pluginManagerErrorTimeoutMillis。
