The problem is that you are running NPM as sudo, so you will only be able to access it using:
问题是您以 sudo 身份运行 NPM，因此您只能使用以下方式访问它：
sudo pm2 start server.js
Install without sudo, you may even install without the -gflag and call it directly from node_modulesdirectory. This may be useful if you do not have root (admin) privileges in the machine you're working on.
无需 sudo 安装，您甚至可以在没有-g标志的情况下安装并直接从node_modules目录中调用它。如果您在正在使用的机器上没有 root（管理员）权限，这可能很有用。
npm install pm2
./node_modules/.bin/pm2 start server.js

Your script needs to do some thing that requires root privilege? (ie: you're getting an error on using port 80)
你的脚本需要做一些需要 root 权限的事情吗？（即：您在使用端口 80 时遇到错误）
[wrong] - trying to run w/ sudo
[错误] - 尝试使用 sudo 运行
[correct] - login as root "sudo su" then do pm2 start app.js --name "whatever" --watch
[正确] - 以 root 身份登录“sudo su”然后执行 pm2 start app.js --name "whatever" --watch
that does it, no need to configure any bashrc or profile files.
这样做，无需配置任何 bashrc 或配置文件。
extra: worried about your app doing crazy shit? (ie, since it's executed as root, the script can use nodejs's exec and do some crazy stuff.)
额外：担心你的应用做疯狂的事？（即，由于它以 root 身份执行，脚本可以使用 nodejs 的 exec 并做一些疯狂的事情。）
hence. do this: do the root-stuff first with your script, then lower your privilege after some timeout:
因此。这样做：首先用你的脚本做root-stuff，然后在一些超时后降低你的权限：
// i use port 80 first.. at this point the script's uid is ROOT.
// 我首先使用端口 80.. 此时脚本的 uid 是 ROOT。
app.listen(80);
应用程序听（80）；
// after 2 seconds we switch to uid AZUREUSER, which obviously isn't root anymore.
// 2 秒后我们切换到 uid AZUREUSER，这显然不再是 root。
setTimeout(function(){
设置超时（功能（）{
process.setuid("azureuser");
process.setuid("azureuser");
}, 2000);
}, 2000);
