如何配置较新版本的 Supervisor 以在 Ubuntu 中随系统启动?有些发行版的存储库落后了。
当我使用简易安装(主管网站默认推荐)时,我只安装了二进制文件,但它没有被守护进程化。

之前有一篇旧帖子提到创建一个 upstart 或 systemd 脚本,多个人尝试不同的方法来使其工作,但没有明确的答案。

虽然文档确实列出了使用 easy_install 来设置监督器的方法,但它也展示了其他方法,例如使用包。包的局限性在于,你会对落后于监督器开发周期的发行版产生依赖。这是一种解决方法,它依赖于向发行版添加外部存储库。如果你认为这不可行,那么请考虑升级你的发行版。如果你只对 System V init.d 脚本感兴趣,请转到文章底部。有一个链接指向社区支持的脚本列表,适用于包括 Ubuntu 在内的不同发行版。
经过一番研究,我发现了以下步骤:安装 Supervisor,然后将其取消进程化,并在 Ubuntu 12.04 中添加一个默认的 Supervisord.conf 文件,该文件在其存储库中有一个旧版本的 Supervisor。
1.-添加 Supervisor PPA 存储库:
sudo apt-add-repository ppa:schooltool-owners/trunk
如果 apt-add-repository 二进制文件不存在,则从现有文件中添加它。

sudo apt-get install software-properties-common
sudo apt-get install python-software-properties
2.- 使用 apt-get 安装 Supervisor
sudo apt-get install supervisor
3.-检查 init.d 目录中是否有脚本。您应该得到类似这样的内容:
#! /bin/sh
#
# skeleton example file to build /etc/init.d/ scripts.
# This file should be used to construct scripts for /etc/init.d.
