这是我采用的解决方案。 AWS AMI 包括用于安装 Python 应用程序的 pip。以下是设置命令:
$ sudo pip install supervisor
$ echo_supervisord_conf
$ sudo su -
$ echo_supervisord_conf > /etc/supervisord.conf
安装 Supervisor 后,您将需要手动构建启动脚本来打开和关闭服务。
这会因您的 Linux 发行版而异,Ubuntu 会在您安装时为您创建一个初始化脚本,而其他发行版(如 AMI)则不会。这里是各种 Linux 发行版初始化脚本的重要资源:
https://github.com/Supervisor/initscripts https://github.com/Supervisor/initscripts
然后,您可以将 Supervisor 添加到 chkconfig,以便在系统重新启动时自动启动。
这是对我有用的一个:
Path
/etc/init.d/supervisord

关闭并保存后,使其可由所有用户执行:
chmod a+x /etc/init.d/supervisord
接下来,您需要通过运行以下命令来确认supervisord进程实际上正在运行:
ps -fe | grep supervisor
如果您没有看到 /usr/bin/supervisord 作为正在运行的进程,那么您需要手动启动它:
sudo service supervisord start
每当服务器重新启动时,Supervisord 都需要启动。这可以类似于使用 chkconfig 重新启动后打开 apache 的方式来完成。
首先将其添加到 chkconfig,您的启动进程列表
sudo chkconfig --add supervisord
然后告诉 chkconfig 在启动后将其打开
sudo chkconfig supervisord on
