AWS OpsWorks 错误：无法重新启动主管服务，因为它不存在

Question

我的 AWS OpsWorks 自定义食谱中有两个食谱

第一个是myserver/recipes/supervisor.rb

 #myserver::supervisor

 supervisor_service "mylistener" do
      command "/usr/bin/php /var/www/listener.php"
      autostart true
      autorestart true
      numprocs 1
      process_name "%(program_name)s-%(process_num)s"
 end

第二个是myserver/recipes/update_code.rb

 #myserver::update_code
 include_recipe "myserver::supervisor"
 execute "update_code" do
     command %Q {
         /usr/local/bin/downloadfile.sh
         /usr/local/bin/changelink.sh
     }
     notifies :restart, "supervisor_service[mylistener]"
 end

supervisor_service 由here 提供。

起初我尝试在运行实例中执行第一个配方。执行成功，supervisor运行顺利。

第二个秘诀基本上是更新主管运行的代码。所以我需要重新启动主管。但是每次执行服务时都会出现此错误。

================================================================================
Error executing action `restart` on resource 'supervisor_service[mylistener]'
================================================================================


RuntimeError
------------
Supervisor service mylistener cannot be restarted because it does not exist


Resource Declaration:
---------------------

9: supervisor_service "mylistener" do
10:     command "/usr/bin/php /var/www/listener.php"
11:     autostart true
12:     autorestart true
13:     numprocs 1
14:     process_name "%(program_name)s-%(process_num)s"
15: end

我做错了什么？

更新

我将include_recipe 'supervisor' 放入文件myserver/recipes/supervisor.rb。

#myserver::supervisor
include_recipe 'supervisor'

supervisor_service "mylistener" do
    command "/usr/bin/php /var/www/listener.php"
    autostart true
    autorestart true
    numprocs 1
    process_name "%(program_name)s-%(process_num)s"
end

但是当我在我的 AWS OpsWorks 中执行 myserver::update_code 时，它仍然在下面返回错误，但有一个新部分 Compiled Resource。

================================================================================

end

更新

我终于用这个手动执行了

execute "supervisor-restart-mylistener" do
    command "supervisorctl restart mylistener:*"
end

但仍在试图弄清楚为什么 notifies 不起作用。

Answer 1

我遇到了同样的错误，但这是由于主管说明书中的错误造成的。 https://github.com/poise/supervisor/issues/43

我恢复到 Supervisor 食谱 0.4.2，它又可以正常工作了。

Answer 2

除非您将这两个配方都包含在 run_list 中或使用 include_recipe，否则此错误是正确的。如果update_code.rb 通知supervisor_service，则supervisor.rb 配方是该配方的“依赖项”。您应该在update_code.rb 的顶部添加以下内容：

include_recipe 'myserver::supervisor'
