How can I set environment variables in my Linux service for Asterisk even though it doesn't have a real user?
提问by domino
I have created a linux service that runs as a deamon (and gets started from /etc/init.d/X). I need to set some environment variables that can be accessed by the application.
我创建了一个作为守护进程运行的 linux 服务（并从 /etc/init.d/X 启动）。我需要设置一些应用程序可以访问的环境变量。
Here's the scenario. The application is a bunch of Perl AGI scripts that depend on (and therefore need to run as) asterisk user but asterisk doesn't have a shell. Ideally I'd just set this in /home/asterisk/.bashrcbut that doesn't exist for asterisk.
这是场景。该应用程序是一堆 Perl AGI 脚本，它们依赖于（因此需要作为）asterisk 用户运行，但 asterisk 没有 shell。理想情况下，我只是将它设置在/home/asterisk/.bashrc 中，但对于星号来说不存在。
How can I set environment variables for my app in the asterisk user's running environment so that my app can use them?
如何在星号用户的运行环境中为我的应用设置环境变量，以便我的应用可以使用它们？

Either set them in the startup script (/etc/init.d/yourdaemon), or put a line in that file that looks like:
要么在启动脚本 ( /etc/init.d/yourdaemon) 中设置它们，要么在该文件中放置一行，如下所示：
. /etc/yourdaemon.env
and put the environment variables in that file, using the syntax export VAR=value. On Red Hat-like systems, I believe the correct place for such a file is /etc/sysconfig. Debian/Ubuntu seems to have /etc/defaultfor this purpose.
并使用语法将环境变量放入该文件中export VAR=value。在类似 Red Hat 的系统上，我相信这样一个文件的正确位置是/etc/sysconfig. Debian/Ubuntu 似乎有/etc/default这个目的。

If your distro of choice is now using systemd try systemctl edit --full asterisk.serviceand consider EnvironmentFileand Environment
如果您选择的发行版现在正在使用 systemd，请尝试systemctl edit --full asterisk.service考虑EnvironmentFile并Environment
These files normally live here: /etc/systemd/system/myservice.servicee.g cron.service
这些文件通常位于此处：/etc/systemd/system/myservice.service例如cron.service
