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。

首先，我尝试在运行实例中执行第一个配方。执行成功，主管运行顺利。

第二个方法基本上是更新主管运行的代码。所以我需要重新启动主管。但是每次我执行服务时都会遇到这个错误。

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


RuntimeError

Supervisor service mylistener cannot be restarted because it does not exist


Resource Declaration:
---------------------
# In /opt/aws/opsworks/releases/20140116091718_218/site-cookbooks/myserver/recipes/supervisor.rb

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？

的更新

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AWS OpsWorks中执行myserver::update_code时，它仍然会在下面返回错误，但是会有一个新的Compiled Resource部分。

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

end

更新

我终于使用了这个手动执行

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

但仍在试图找出notifies无效的原因。

Answer 1

我得到了同样的错误，但这是由于主管食谱中的一个错误。 https://github.com/poise/supervisor/issues/43

我又回到了主管食谱0.4.2，它再次正常工作。

Answer 2

除非您在run_list中包含这两个配方或使用include_recipe，否则此错误是正确的。如果update_code.rb通知supervisor_service，那么supervisor.rb食谱就是该食谱的“依赖关系”。您应该将以下内容添加到update_code.rb的顶部：

include_recipe 'myserver::supervisor'

AWS OpsWorks错误：无法重新启动Supervisor服务，因为它不存在
