在AWS AMI Linux服务器上设置Supervisord

Question

我正在努力让主管努力确保我的队列系统始终在运行.

以下是我采取的步骤,我从各种来源拼凑而成:(以root身份或超级用户身份)

1)$ easy_install主管

2)$ echo_supervisord_conf> /etc/supervisord.conf

3)$ sudo vi supervisord.conf

4)将以下内容粘贴到文件末尾:

command =/usr/bin/php/path/to/AppName/artisan --env = production --timeout = 240 queue:listen

5)$ supervisord -c /etc/supervisord.conf

6)$ supervisorctl

7)主管>状态

主管>

它没有显示任何内容.

Answer 1

这是我选择的解决方案.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,您需要手动构建启动脚本以打开和关闭服务.

这将因您的Linux发行版而异,Ubuntu会在您安装时为您创建一个init脚本,其他发行版(如AMI)则不会.这是各种Linux发行版初始化脚本的绝佳资源:

然后,您可以将管理程序添加到chkconfig以在系统重新引导时自动启动.

这是一个适合我的方法:

路径

/etc/init.d/supervisord

        echo $"Usage: $prog {start|stop|restart|condrestart|try-restart|force-reload|reload}"
        RETVAL=2
    esac

    exit $RETVAL

关闭并保存后,让所有用户都可执行:

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

如果您没有将/ usr/bin/supervisord视为正在运行的进程,则需要手动启动它:

sudo service supervisord start

需要在重新启动服务器的任何时候启动Supervisord.这可以类似于使用chkconfig重启后如何打开apache.

首先将它添加到chkconfig,即启动进程列表

sudo chkconfig --add supervisord

然后告诉chkconfig在启动后将其打开

sudo chkconfig supervisord on

主管不知道您已添加程序。这是在 serverfault 上回答的，请执行以下操作：

supervisorctl reread
supervisorctl update

顺便说一句，使用conf.d语法更容易维护配置文件。换句话说，创建一个名为/etc/supervisor/conf.d/artisan.conf. 其他一切都一样，但更容易对配置文件进行版本控制并将它们同步到设置的机器上。
