在AWS AMI Linux服务器上设置Supervisord

问题描述 投票:20回答:2

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)$须藤力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

它没有显示任何内容。

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

主管不知道你已经添加了一个程序。 This is answered on serverfault,执行以下操作:

supervisorctl reread
supervisorctl update

顺便说一句,使用conf.d语法维护配置文件更容易。换句话说,创建一个名为/etc/supervisor/conf.d/artisan.conf的文件。其他一切都是相同的,但是更容易对配置文件进行版本控制并在设置时将它们同步到机器上。
