关于为什么厨师中的这个片段失败的任何想法？

bash "Stopping service" do
  user #{user}
  cwd "~/"
  code <<-EOH
    killall -q java
  EOH
end

您可以定义returns，使用参数接受哪些返回码

bash "Stopping service" do
  user #{user}
  cwd "~/"
  code <<-EOH
    killall -q java
  EOH
  returns [0, 1]
end

这可能意味着killall没有找到任何java要杀死的进程，并以状态码退出1。

状态代码0表示成功，任何其他代码都是某种失败。

如果您省略该-q标志，您将能够在 Chef 失败时看到命令的输出（或者您可以登录到该框并手动尝试），可能类似于：

java: no process killed

如果您绝对希望这在任何情况下都不会失败，exit 0请在脚本末尾添加 a：

code <<-EOH
  killall java
  exit 0
EOH
