我有一个DigitalOcean Droplet，将laravel应用程序投入生产后，我尝试了以下命令：
sudo systemctl重新加载nginx
但是我得到这个错误：
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
我运行sudo nginx -t看看是否有错误，但是conf和语法还可以，之后我就运行了：
sudo nano /var/log/nginx/error.log
我明白了：

不管为什么我不能重新启动Web服务器，我的网站仍然可见，但似乎无法重新启动或重新加载Nginx。
答案 0 :(得分：1)
似乎是<script src="https://bundle.run/lit-element@2.2.1"></script>
<drop-down-menu>
<li>Item 1</li>
<li>Item 2</li>
</drop-down-menu>的问题，由于某种原因它是空的。
第一个检查进程google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['Year', 'Data', 'Id'],
['2004', 400, 'Expenses'],
['2004', 1000, 'Sales'],
['2005', 1170, 'Sales'],
['2005', 460, 'Expenses'],
['2006', 660, 'Sales'],
['2006', 1120, 'Expenses'],
['2007', 1030, 'Sales'],
['2007', 540, 'Expenses']
]);
var options = {
title: 'Company Performance',
curveType: 'function',
legend: {
position: 'bottom'
}
};
// create data view with columns for each id
var view = new google.visualization.DataView(data);
var aggColumns = [];
var viewColumns = [0]; // <-- include x-axis as first column
data.getDistinctValues(2).forEach(function (id, index) {
// add view column for id
viewColumns.push({
calc: function (dt, row) {
if (dt.getValue(row, 2) === id) {
return dt.getValue(row, 1);
}
return null;
},
label: id,
type: 'number'
});
// add agg column for id
aggColumns.push({
aggregation: google.visualization.data.sum,
column: index + 1,
label: id,
type: 'number'
});
});
view.setColumns(viewColumns);
// aggregate data view
var aggData = google.visualization.data.group(
view,
[0],
aggColumns
);
var chart = new google.visualization.LineChart(document.getElementById('curve_chart'));
chart.draw(aggData, options);
});找到nginx的thre根进程（在我的情况下为<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="curve_chart"></div>）
/run/nginx.pid然后杀死它：
ps -ef | grep nginx然后重新启动nginx 7388
root@keybu:/var/www/keybu_production# ps -ef | grep nginx
root 2314 9443 0 21:28 pts/0 00:00:00 grep nginx
root 7388 1 0 2019 ? 00:00:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
nginx 23709 7388 0 Jan15 ? 00:00:04 nginx: worker process
，但尚未对其进行测试
