如何运行pm2，以便其他服务器用户可以访问该进程? [英] How to run pm2 so other server users are able to access the process?

问题描述

当我使用 pm2 启动Nodejs应用程序时，其他服务器用户将无法访问该进程.

When I start my Nodejs app with pm2, other server users are not able to access the process.

即使我从自定义目录(不是当前用户的~/，默认情况下，pm2在使用什么)启动pm2:

Even if I start pm2 from a custom directory (not current user's ~/, what pm2 is using by default):

HOME=/var/www pm2 start app.js

任何用户都可以访问目录(与~/相比，但是其他服务器用户仍然无法访问该进程.

Directory is accessible by any user (comparing to ~/, but there's still no way other server user is able to access the process.

当其他服务器用户执行pm2 list时，表明他正在运行0个进程-但有(正在由另一个用户启动).当其他用户尝试HOME=/var/www pm2 list时，CLI会引发错误:

When other server user does pm2 list, it shows him 0 processes are running – but there are (started by another user). And when other user tries HOME=/var/www pm2 list, CLI throws an error:

events.js:72
    throw er; // Unhandled 'error' event
          ^
Error: connect EACCES
    at errnoException (net.js:905:11)
    at Object.afterConnect [as oncomplete] (net.js:896:19)

所以我想知道如何确保用户能够访问其他服务器用户运行的pm2进程?还是应该采用不同的方法?

So I am wondering how to make sure users are able to access pm2 processes run by other server users? Or it shall be approached differently?

我想知道为什么每个服务器用户都能使git pull从Git存储库中部署最新的源代码，但之后又不能重新启动pm2进程?只有启动pm2进程的用户才能重新启动它…很奇怪.

I am wondering why every server user is able to make git pull to deploy latest source code from a Git repository, but can't restart pm2 process afterwards? Only the user that started pm2 process is able to restart it… Weird.

推荐答案

这是我们绕过此问题的方式.

Here's how we bypassed this.

只需创建一个组

• 创建一个新组pm2或任何适合您的名称

$ groupadd pm2

将/var/www/文件夹组所有者更改为组pm2

Change the /var/www/ folder group owner to group pm2

$ chgrp -R pm2 /var/www

将另一个用户(例如bob)添加到pm2

Add the other user, let's say bob, to pm2

$ usermod -aG pm2 bob

现在bob可以通过将$ HOME更改为/var/www

Now bob can run pm2 commands by changing $HOME to /var/www

$ env HOME=/var/www pm2 list

或者(更好)创建一个@jcollum建议的别名

Or (better still) create an alias as @jcollum suggested

$ alias pm2='env HOME=/var/www pm2'
